2017 Hyundai Tucson Complaint Log

MY engine check engine light and than a warning light came on saying not to drive it and i took it to be repaired at a shop and a hyndai dealer and they told me my engine needed to be replaced even though i always serviced my car. It has 103,000 miles on it. It is the same problem as the other person that reported this problem. The other models were recalled but not this one. Im sure by now you know there is a problem with this engine too. It should be replaced by the company!!

Excessive oil consumption, Full synthetic Oil last less than 2000 miles. Transmission takes some time to respond when start driving from a stop. Car shake a bit.

Burning oil. More than a quart every couple hundred miles sometimes much more than that. Very bad burning oil smell coming from engine into the inside of my car. I feel sick everytime I drive from breathing in fumes. Need oil consumption test asap

My 2017 Hyundai Tucson has been chonking out and having acceleration problems. I thought it was because of AC running. When I took it in for inspection my mechanic stated it was misfiring. I am meticulous about routine maintenance (I.e. tire rotation and/or replacement, oil change, inspection, etc), as well as whatever if any repairs are needed. I immediately reached out to my local Hyundai dealer but they never responded. It should be corrected by Hyundai and a recall issued. After researching the issue I see I’m not the only one with a problem. The 1.6 L engine should have been recalled because apparently the same turbo engine in the GDI model was. I have all my maintenance records to support my claim. Come Hyundai!!! I thought you stood behind your vehicles?????

Electric,

Every time I get the oil changed I have to add 2-5 quarts of oil in between changes. I had the catalytic converter replaced 3 years ago and now I have to do it again. I’ve had nothing but issues with this car and oil consumption. I shouldn’t need another catalytic converter again after only a few years. I’m doing my 3rd oil consumption test right now.

While driving to work on I-26 in the far left lane at approximately 55 mph, my vehicle suddenly and completely shut off without warning. The engine power was lost instantly, forcing the car to come to an abrupt stop in live interstate traffic. I had no prior indication of a problem—no warning lights, no messages, no abnormal performance. It took three attempts to restart the vehicle. When it finally restarted, the engine made a loud knocking noise, and the car could only move at a dangerously slow crawl. I had to cross multiple lanes of high-speed traffic to reach the right shoulder, nearly causing several accidents in the process. Other drivers had to brake hard and swerve to avoid colliding with me. This situation could have easily resulted in a multi-vehicle crash, severe injury, or death. After pulling over and shutting the vehicle off, I checked the oil dipstick and found it completely dry. The engine had failed with no warning whatsoever. The vehicle was later inspected at an independent service center and I was told the engine must be replaced, and that the vehicle is not safe to drive. I am now left without reliable transportation due to this sudden failure. This incident represents an extreme safety hazard. Losing all engine power in the far left lane of an interstate at highway speeds placed my life, and the lives of countless other motorists, in immediate danger. The outcome could easily have been catastrophic. To reiterate: the engine failed without any warning or indication, creating a life-threatening emergency situation. This is a critical safety defect that requires urgent investigation.

Component/system: Engine / powertrain – excessive engine oil consumption. The original engine is still in the vehicle and is available for inspection upon request. On 11/7/2025 my dealer (Ourisman Hyundai in [XXX] ) added 2 quarts of oil at 90,999 miles after the dipstick showed a very low level. After that visit, we drove approximately 713 miles (mostly highway, including a college visit trip), and the oil level again dropped close to the same low point on the dipstick. On 11/22/2025 at 2:10 PM, with mileage at 91,815, the dipstick again showed a significantly low oil level. I am concerned that this abnormal oil consumption could lead to sudden engine failure or loss of power while driving at highway speeds, putting my family and others on the road at risk. This vehicle is used regularly for my daughter’s college visits and everyday transportation. The dealer has acknowledged the concern, previously performed a combustion chamber cleaning on 8/11/2025 (Invoice #XXX), and has submitted a request to Hyundai for assistance. However, a formal oil consumption test or official diagnosis has NOT yet been completed, so the exact cause is UNKNOWN. The vehicle has been inspected by the dealer, and Hyundai Motor America has opened a case, but there has been no final decision or repair yet. There have been no warning lamps or messages on the dashboard; the only symptom has been repeated, excessive oil loss between visits, verified by multiple dipstick and odometer photos. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Loud knocking in the engine that increases or decreases with the rpm. Metal shavings found in the oil. Appears to be same issues described as active recall for 2017 Tucson’s, but no recall for this vin. No alerts were or have been triggered within the car. This has not been brought to a dealership out of fear of seizing the engine.

NHTSA Complaint – 2017 Hyundai Tucson Oil Consumption, Engine Defect, and Branded Title I am filing this complaint regarding my 2017 Hyundai Tucson, which suffers from abnormal oil consumption and engine problems. In addition, Hyundai Motor Company internally “branded” the title without disclosure, which voided my eligibility for warranty coverage. These issues create both serious safety risks and consumer protection concerns. 1.Oil Consumption and Engine Issues •This Tucson has had oil consumption problems since the first owner, which I only discovered a year after purchasing the vehicle. •The vehicle burns oil excessively between service intervals, often requiring top-offs after just a few hundred miles. •Critically, the low oil pressure warning light provides no early warning. It only activates once oil levels are already dangerously low, leaving no safe margin to protect the engine. •On multiple occasions, I was unaware the engine oil had dropped to unsafe levels until the vehicle was already at risk of engine damage. •The engine makes knocking/tapping noises, hesitates under acceleration, and has rough idling when oil levels drop — all signs of internal engine damage that could lead to sudden failure while driving. 2.Hyundai’s Branded Title Practice •Roughly one year after purchasing from CarMax, I learned that Hyundai had internally branded the title in their own system due to oil consumption reported by the first owner. •This branding was never disclosed to me or to CarMax, and the official state-issued title and Carfax report both showed “clean.” •Hyundai uses this internal branding to void the extended engine warranty that should have applied to my vehicle. •Despite repeated requests, Hyundai has refused to provide documentation of when or why this branding occurred. 3.Warranty and Safety Concerns •Hyundai has issued Technical Service Bulletins (TSBs) and extended warranties for engine failures caused by piston rings and bearings

excessive OIL CONSUMPTION no leaks its buring oil

This unresolved issue has created serious safety risks. On two separate occasions, my vehicle lost power while crossing the Leo Frigo Bridge in Green Bay—an extremely dangerous scenario for both my family and other drivers. Most recently, within just ~40 miles of picking up the vehicle from service, the issue recurred. The service department reported finding oil on the ignition coils—symptoms consistent with known and documented warranty concerns such as: Valve cover gasket leaks Spark plug tube seal failure High-pressure fuel pump gasket leaks The vehicle has been brought multiple times to a certified Hyundai dealership for recurring problems including power loss, poor engine performance, and excessive oil consumption. Despite these repeated service visits, the underlying issue has not been properly addressed. I have now been informed that I am responsible for diagnostic charges—even though the vehicle is covered under the TXXM Engine Warranty Extension / Powertrain Limited Warranty due to known oil consumption-related defects.

The contact owns a 2017 Hyundai Tucson. The contact stated that while attempting to accelerate, the transmission failed. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired, but the failure reoccurred. The contact stated that while driving approximately 25-30 MPH, the vehicle was making an abnormal rattling and knocking sound that was coming from the engine while accelerating. The transmission was shaking continuously while driving at 10 MPH. The vehicle was taken to the local dealer, where it was diagnosed with camshaft and engine failure and needed a cam finish over an advanced timing system overhaul. The contact was informed that the camshaft, CVT, timing chain and tensioner, front valve cover and valve cover gasket, turbocharger, turbocharger gasket, and turbocharger lines needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 92,000.

The vacuum pump cap was diagnosed as the issue. All the lights came on the dash. I lost power steering and speedometer. There has been recalls for other years.

The controls (buttons) on the right side of my steering wheel progressed from slow to respond to completely unresponsive, and then the driver airbag light started coming on. At first it was intermittent, then constant. I didn't expect those two issues to be related but did come to learn it was the clock switch. According to my Hyundai dealer, this is a known issue in several other years/models of Hyundais and they have extended those warranties, "but it hasn't reached the Tucson yet". I was told that either 1 - my airbag wouldn't deploy or 2 - it would deploy randomly when I was driving the vehicle. I spent nearly $1000 in diagnostics and repairs.

My 2017 Hyundai Tucson 1.6 liter is experiencing severe engine issues that closely mirror those subject to recent class action lawsuits. The engine exhibits excessive oil consumption. I have experienced a sudden loss of power on roadways in traffic as well as on the highway. This issue happened just today. Unfortunately due to a loss of smell, I have been unable to smell if there has been burning oil, however in between my last two oil changes (I only bought the car in October) I had to go it to get it refilled or refill it myself. I use full synthetic oil as well. I brought it into a reputable mechanic and I have been told if I continue to drive the vehicle the excessive oil consumption will lead to premature engine failure, potentially causing a dangerous stall or accident, putting myself and other motorists or pedestrians at risk. The mechanic received codes P0420, P0300, P0302, P0303, and P0304. They were able to conclude oil consumption based on the low amount of oil in the vehicle, the spark plugs being oil fouled, the misfiring on three cylinders, and the P0420 code. I called customer service, the Hyundai dealership in Clive, IA, and the contact for the class action lawsuit and litigation II. I was informed my VIN number was not part of the current recalls or class action, however the symptoms are identical to those widely reported. In the litigation my make and model are mentioned, Hyundai Tucson 2017, however it is listed as the 2.0 liter engine. My engine is mentioned, the 1.6 liter, in at least one other vehicle. I believe this vehicle was only excluded by a lack of representation at the time of the litigations. From my call with the dealership, and in research I am not the only one experiencing this problem. While I was lucky enough not to have been harmed, this has the potential to cause great harm. As someone who works for a DOT, safety first is in everything I do. I believed this necessary to report for the safety of all those involved.

The engine blew. It had to be replaced at my costs because hyduadai does not warrant when a car changes hands. It has 81250 in miles. This is happening to lots of people. It’s a 1.6 L engine. The 2.0 has a recall. But the 1.6 needs to be recalled also. Something needs to be done.

The vehicle has a transmission (powertrain) malfunction that first appeared in July 2025, a few weeks after I purchased the vehicle and after the warranty had expired. At the time the issue began, the vehicle had well under 80,000 miles. The transmission slips, fails to properly engage, and cannot provide sufficient power, particularly when accelerating or driving uphill. The vehicle struggles to move forward and behaves unpredictably during normal driving conditions. This defect has put my safety and the safety of others at risk. On one occasion, the transmission failed while I was driving and I became stuck in the middle of an intersection, unable to accelerate, creating a serious traffic hazard. The issue has been reproduced consistently and has persisted despite repeated transmission fluid services. Multiple mechanics have inspected the vehicle and have indicated that the problem is not due to lack of maintenance, but instead is likely caused by the transmission not being properly filled with transmission fluid at the time of manufacture. Despite servicing, the problem continues, indicating an internal or manufacturing-related defect. I have also been in contact with multiple owners of the same make and model vehicle who report the same transmission failure, suggesting this is a widespread issue rather than an isolated incident.

Seat belt is coming a part driver side burning oil to the point needs a new catalytic converter

My car has been consuming large amounts of oil and as a result has had two catalytic converters replaced. Twice now we have been disabled on the highway due to aggressively poor engine performance.

The car has issues with major oil consumption, and a chatter engine noise, also has issues with acceleration. Oil will run dry if not topped off every 3 weeks.

On [July 4, 2025], while driving, my vehicle experienced a sudden loss of power followed by smoke and flames coming from the engine compartment. The fire required emergency response and caused significant damage to the vehicle. Thankfully, no one was injured, but the incident posed a serious risk to my safety and others on the road. I had not received any prior warning signs such as engine knocking or warning lights. The fire appears to be directly related to the known defect outlined in Recall 209. I am requesting that NHTSA investigate this incident and ensure Hyundai is held accountable for the full scope of this defect, including fire risk. I am also seeking assistance in ensuring Hyundai provides appropriate compensation or resolution for the damages caused.

The engine in my 2017 Hyundai Tucson Limited failed at approximately 111,000 miles. The vehicle began to run roughly, misfiring and losing power with no warning lights or prior indication of an issue. Within days, the vehicle became undriveable and had to be towed to a dealership. The dealership diagnosed the issue as a cylinder misfire due to internal engine damage caused by excessive oil consumption. They confirmed the only solution was a full engine replacement. I was told this issue is not currently covered by recall, despite its similarity to known engine defects Hyundai has recalled in other vehicles. This failure posed a serious safety risk. The vehicle stalled and lost power while driving, making it dangerous to accelerate or keep pace with traffic. Fortunately, the failure did not cause an accident in my case, but it easily could have in different circumstances. There were no dashboard warning lights, oil pressure warnings, or check engine indicators before the symptoms began. The oil level had not been excessively low, and the car had been well maintained. I have opened a case with the manufacturer, but assistance was denied due to mileage and ownership history. This appears to be part of a broader pattern of engine failure in similar Hyundai models. I am reporting this in hopes it contributes to further investigation and potential recall expansion.

My door to drivers side only fully unlocks from the inside. When my door is locked it now requires me to climb through another door of my car and pop open the drivers door. If I were to get in an accident people wouldn’t be able to get me out if I was incapacitated.

limp mode check engine light code p1326

My engine was recalled and they inspected it and said it was fine in 2023. Fast forward to June 2025, My engine failed. I took it back to the dealership and they tested it and said "it was not bad enough to be fixed under the recall." Before I took it the dealership the check engine light was on, reduced power when accelerating, knocking noise from the engine that increases when the rpms increase, and the oil pressure light is flashing. Upon taking it to the dealership the check engine light has been turned off, but all the other issues still remain. All of these issues were components to the recall. I have called Customer Care and they assured me that it would be fixed at no cost under the recall, and then I requested a different dealership due to terrible customer service at the prior dealership. Customer Care then contacted prior dealership, and went based on the incorrect findings of the dealership, they are refusing to fix my engine that is under recall. Because they inspected it in 2023 they marked the recall campaign as closed.

Vehicle Make/Model/Year: Hyundai Tucson 2017 NHTSA: Recall Number 21V727000 Description of Problem: My vehicle is affected by a known safety recall related to the engine (likely recall campaign P1326 or similar, affecting Hyundai engines). I contacted the authorized Hyundai dealership to schedule the recall service. However, the dealership is requiring me to pay out-of-pocket for parts and/or tests — specifically, they mentioned charging for testing engine gaskets/joints — before confirming whether they will replace the engine under the recall. The recall notice clearly states that diagnosis, testing, and any necessary engine replacement should be done at no cost to the consumer. The dealership’s request for payment appears to be in violation of federal recall laws. I am being forced to delay this safety repair because I cannot afford these unexpected charges, which I believe are not allowed under NHTSA recall policies. This compromises my safety and could affect many other consumers in the same situation. Please investigate this dealership’s handling of the recall. I am requesting that Hyundai be held accountable for ensuring proper and legal recall service.

Car cuts off when driving the speed drops down automatically stops the dash lights go out and can’t start it right away

I have a 2017 Hyundai Tucson with approximately 120,000 miles. The vehicle had issues with oil consumption and jerking when put into drive. I took the vehicle to the dealership to be checked and was told it was fine. I recently was driving at 70 mph when the engine light came on and lost power. I had it towed to a mechanic that checked and cylinder #3 had lost compression. After finding this out I did an internet research and found that this is a common issue with this motor and vehicle. My vin is not included in the recall but Hyundai has replaced other engines in “goodwill” when the vin number was not included. One search shows that it usually happens from 120,000 to 150,000 miles. After the mechanic looked at the vehicle, Hyundai instructed me to take it to a dealership. After another tow to the dealership they said it was only the spark plugs but upon futher investigation they found that the cylinder was damaged with scoring to engine. The cost for a used engine with 54,000 miles is 10,000 and is more than the value of the car and the remaining loan amount of 10,000. So far we are out approximately 300.00 in towing fees. The dealership has not yet billed us for the checking they have done. We have contacted Hyundai with a response of no help to replace the engine even though the company has helped others in our situation. We haven’t replaced the motor due to the amount owed, cost of used motor vs the value of the vehicle. The safety of the vehicle is very questionable due to the high incidence of this happening and there could have been catastrophic consequences if I would not have been able to pull off the road.

The contact owns a 2017 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the low oil light illuminated, and the vehicle was shaking abnormally. The contact added oil to the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed with oil shavings in the oil pan and engine failure. The contact was informed that the engine needed to be replaced. The dealer was made aware of the failure but provided no assistance. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 101,000.

I was returning home from a 224 mile trip. I was driving 65mph with the AC on low. Vehicle started slowing and losing power. I pulled over at the next possible location when I noticed the engine light was blinking then stayed solid yellow. I tried to rev the engine a few times only to be met with engine shutter and misfire. Had to have the vehicle towed the remaining 65 miles home. Took the vehicle to my mechanic where he stated cylinder 3 and 4 misfiring and told me this is a common problem with this vehicle. After doing my own investigations, I see this vehicle has an extensive history of the same problem from several other people. But yet no recall.... Why?

While driving, the vehicle started knocking and jerking, lost power and began to run roughly. The check engine light initially flashed and then turned solid before the vehicle shut off. The next day, I took the vehicle to the dealership for a diagnostic after experiencing problems with knocking when the check engine light illuminated. The codes were P302 and 304 indicating misfiring. The diagnostic tech wrote the problem up as having oil in the cylinder and suggesting engine/turbo replacement for approximately $15,000.00. The engine has less than 100,000 miles. I asked about the 10/100. After inquiring about the recalls for GDI engines in the 2017 Tucson for rods causing engine fires due to oil leaking into the cylinders, the service agent stated that it was only the 2.0 and not the 1.6 with recalls. I said sir it is the same issue: high oil consumption, sputtering and knocking, check engine light indicating misfire. Now the oil is accumulating in the cylinders. He stated that because I am the secondary owner neither the dealership nor Hyundai will correct the problem. However, if I was the original owner the powertrain warranty would cover the repair. The problem with the 2017 GDI, DCT in the Tucson is a safety issue for all owners. Escalated the issue to Hyundai Motor America, agent Kyrillos, who said that he would contact the dealership to check for prior authorization with the dealership to see if they would cover it under the recall. After numerous calls (on my behalf) and finally speaking with Kyrillos, I was advised that the dealership denied the repair. I requested supervisor contact and have not had any further communication from the company. I did send a follow up email asking when I could expect to hear from them.

It is my belief that the engine is failing or has something wrong, due to an engine recall. I started having issues with acceleration and took it to a local mechanic who advised it was an engine issue and needed to be taken to the Hyundai dealer asap. As of today, May 27, 2025, it was taken to Autonation Hyundai in Columbia, SC who is alleging that all engine recalls related to my vehicle are not covering any engine issues. I have had this car for quite a while and have never had any issues until now. Multiple diagnostics have been performed.

Blind spot warning stopped working due to electric issues. Engine started miss firing causing a turn over issue and loud knocking. Brought to auto shop and was diagnosed that engine is failing.

1)Component that failed: Engine 2)Driving 75 miles on the interstate in traffic and suddenly losing speed was very dangerous. 3)Yes, the issue is still occurring, even worse now as my vehicle shakes just starting the engine. 4) The mechanic has inspected, diagnosed and attempted to repair. However due to the condition of the engine, and the cost of replacing it; fixing may not be an option. 5)The engine light began flashing and then went off; then back to steady on. I purchased this 2017 Hyundai Tucson used just 4 years ago. Everything seemed to be working just fine, I've had regular oil changes. On Saturday, May 10, 2025, as I was driving on the Interstate with my cruise control set, I began to lose power and my speed slowed. I took my car off of cruise control and pushed on the gas pedal to gain speed and my car started to shake and it struggled to pick up speed. My mechanic has changed the spark plugs and performed a BG upper engine induction cleaning; did compression testing and leak down testing. He found that cylinder 4 has no compression. In addition to that, he noticed there was oil on the spark plug. I had my oil changed 3 months ago, and less than 3,000 miles - my engine is burning up the oil to the point where the oil level is extremely low. I have now found out that this is a known issue with this type of vehicle. I'm told it's $10,000 to replace the engine. I have no warranty coverage since I'm not the original owner. I was not aware of the class action lawsuit that was settled last year. I'm extremely upset that Hyundai has not recalled ALL the engines for this make and model of vehicle as it seems EVERYONE has had engine problems.

Oil consumption issues upon oil change no oil registered at all. It was confirmed no leaking and was advised to contact due to recall on this motor using oil. Also advised to request request a motor replacement due to this vehicle already showing signs of this issue to assure it doesn’t lock up.

The power steering of the vehicle suddenly stopped working. We had the car towed, and after inspection we were told that the steering column had failed. We were expected to purchase a new original part from Hyundai, which we did. After waiting a week, we were told that the replacement that was sent did not work and was defective. This has happened again and again, and we are currently waiting for our 4th part from Hyundai. Hyundai corporate told our auto shop that they "opened a case" to see why these parts are defective. I'm hoping that they eventually get to the bottom of this and can fix our Tuscan. We were lucky that our steering column failed on the driveway at our home, but I would imagine it could case quite a bad accident if power steering went out suddenly on someone else.

My car became disabled due to engine failure on the highway. My vehicle is no longer drivable. My warning lights did not come on prior to the incident.

I was driving home from the store a short distance from my home. The check engine light came on, the car ran rough, lost power and would not accelerate. I was able to get home. My husband checked the oil; it was 2 quarts low. He previously changed the oil 3000 miles prior. He connected a code reader and it read "DCT 1326". I drove slowly on the berm of the road & able to get home. Had I been on an interstate, my life could have been endangered. Top speed a rough 30-40 mph. After my internet search it appears that oil consumption and engine loss is a common problem. My car has less than 60K miles. No prior history and oil changed every 5K miles.I am very upset about the lack of responsibility on Hyundai's part. This is our 3rd Hyundai and we were loyal customers. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

No compression in one of the cylinders, oil blow by, oil consumption approx 1 quart per 1000 miles. Now has developed a serious miss in cylinders 2 and 4 and is undrivable.

The engine is failing. Our vehicle continues to experience tremendous oil consumption and it's all of a sudden gone into "limp mode" where we lose engine power even after the knock sensor recall update was performed. No check engine lights, no indication of what's happening and it just loses power on the highway as well as city streets. It's a danger to everyone around us and it's a danger for us as we try to drive the vehicle. The dealer / Hyundai had us do 2 oil consumption tests but would not do anything to fix the issue. They informed us they needed to replace the engine after the first oil consumption but then they backed off of that and didn't fix the issue. It’s just gotten worse. We also had a transmission service done and they said the transmission looked fine. We took it in for a diagnostic just after this as the power issue began in "limp mode" where we lose engine power. They are trying to say it needs a new transmission but with the known issues with the Hyundai oil consumption and engine issues where the vehicles go into power loss / limp mode, we’re reporting this issue for our safety and the safety of the community as it’s unsafe to drive this care. We hope you will push Hyundai to do a recall for the engine not just for us but for all Hyundai Owners who are dealing with the same issue.

Sole owner of 2017 Hyundai Tucson with approx 55,700k miles. Check engine light on and car not accelerating properly. Had same acceleration problem a year ago without engine light, Hyundai dealership stated I needed software update on anti judder gds, update was completed by Hyundai and the issue has reoccurred.

While driving under normal conditions, the engine began misfiring and losing power. Inspection revealed that two of the spark plugs had suffered a broken ceramic insulator, which likely occurred during a pre-ignition or detonation. As a result, the ceramic insulators were pushed through the engine causing at least one of the exhaust valves to burn leading to loss of compression resulting in engine failure on the highway. This engine has no current recall, despite numerous similar complaints. Hyundai has issued detonation-related recalls for other engines (like the Theta II), yet the 1.6L Turbo GDI engine in this Tucson is also experiencing similar failures. At the time of this complaint there are 955 complaints in the NTHSA database about this vehicle with more than half citing engine failure issues — many of them sudden and severe failures while driving. This creates both a safety risk and an excessive financial burden. These failures occur without warning and can leave the driver stranded. It is concerning that Hyundai has not acknowledged a defect pattern, despite consistent failure modes being reported across this engine type. I am requesting that NHTSA investigate the 1.6L Gamma II Turbo engine for potential systemic detonation or pre-ignition issues that can lead to severe engine damage. A recall or special service campaign should be considered, and Hyundai should be held accountable to cover these repairs.

My engine needs to be replaced. Out of nowhere it failed. No stuttering, no stalling, no check engine light or any other warnings. Just failed.

While driving down the interstate the vehicle would not accelerate and the RPMs were fluctuating. We were luckily near an exit and were able to pull into a gas station. The check engine light came on. Once we parked the engine stalled and we were not able to restart. We had the vehicle towed to a AAA certified mechanic, they stated there was no oil and that the engine needed to be replaced. We did not receive any low oil indicators for the vehicle. We had the vehicle flat bed towed back to our home town where a 2nd mechanic indicated that there was still some oil in the vehicle but that the engine would need to be replaced. The VIN for this car shows no engine recall but this appears to be the same issue that has resulted in Hyundai engine recall with the 2.0 vehicles.

Car is burning oil. Oil change done at 3k and no oil in vehicle at all. Transmission shakes violently on start up and first movement and slips shifting gears. No response sometimes when pressing gas pedal to go

Engine experienced a catastrophic failure. Driving (normal commute) and clicking noise start coming from the engine. Got louder over a short time, but no dash waring lights came on. Further along the check engine light came, and when it started flashing I pulled over and called for roadside assistance (tow). No other warning lights came on. Engine temp read normal throughout. After the dealer service team reviewed, said the engine block was cracked and metal noted in the oil and filter. I contacted Hyundai USA to see if they would cover engine replacement. After a few days of review and back and forth with the dealer, they declined any claim. Dealer service rep quoted us approx $20k for engine replacement. We opted to sell to salvage company and now need to buy another car. Just over 66,000 miles and complete loss.

Hyundai Tucson 2017 – Known Transmission Defect Ignored I own a 2017 Hyundai Tucson with the dual-clutch transmission. For months I experienced serious hesitation and sputtering when accelerating from a stop or low speed—a clear safety risk when trying to merge into traffic or cross intersections. On July 23, 2025, I dropped my vehicle at Huffines Hyundai in Plano. It sat there for nearly a month until August 21, when they finally admitted they could reproduce the issue. The problem matched exactly what Hyundai itself identified in its own service bulletins regarding this model’s transmission. Despite acknowledging it’s a known defect, Hyundai: Refused to cover the repair, Would not even reimburse my $200 third-party warranty deductible, Has failed to issue a recall, leaving countless owners with the same unsafe problem. This is deplorable customer care. Hyundai and its dealerships know this defect exists, can reproduce it, and yet leave customers to pay out of pocket for a manufacturer-caused safety hazard. Buyers should beware—Hyundai is not standing behind its vehicles.

Car went into limp mode on the highway because of high oil consumption. Car came to a complete stop.

The transmission failed, and it's only at 70k. This was only diagnosed AFTER being told that my dual clutch was faulty. I had that replaced, only to be told that my actuator was faulty and NOT the clutch, after haviing paid for the replacement. Now, the vehicle will barely move with rpms through the roof. So not only was Ithe vehicle misdiagnosed TWICE, the cost of repairs was sky high! This could have been avoided. I contacted the dealerships, at they advised that they did everything as hyundai instructed them. Well, hyundai was wrong, and now my vehicle doesn't even work.
