2017 Hyundai Elantra Complaint Log

Identical problem also reported under NHTSA 11632482 to an individual on other side of US and other report numbers for this 2017 Hyundai Elantra. This is a re-occurring hazard. Rear door while unlocked will not open from either inside or outside of vehicle. Very dangerous for passengers. I assume it is the door actuator.

Hi the smart junction box on this vehicle is acting up. When riding in free way all doors locked open automatically and then the headlights just went off, and all the 4 blinkers stopped working creating hazard to all people in the freeway including mine . Mechanic has quoted me 2k to fix the issue and replace the Smart junction box . Please provide me fairness in this matter

Timing chain looseness, Sudden loss of engine power/motive power. Vehicle was sold, unknown if available for inspection. Engine failure on and in the middle of the interstate/highway, and this caused a major crash risk, and safety hazard. This make and model of vehicle has multiple reports of similar incidents. The repairs would’ve cost over 3 times the value of the car. As stated by the vehicle manufacturer, the entire engine would need to be replaced, with a factory built engine in order to comply with NHTSA and safety regulations. I’m no longer in possession of the vehicle. It was sold. While the vehicle was operating, and drivable there would be a chime and a flashing check engine light/indicator on occasion. Although no codes were present at maintenance center, therefore unable to identify the exact cause.

unknown, stalls randomly after driving for about 10 minutes

I am filing a formal complaint regarding my 2017 Hyundai Elantra SE (VIN: [XXX] ). The vehicle is currently experiencing severe safety issues, including unexpected engine stalling and loud mechanical rattling, alongside a P0014 diagnostic code. These symptoms align directly with the defects described in Recall 203 (NHTSA 21V301000) involving improper piston ring heat treatment and Service Campaign 966regarding engine bearing wear. As a consumer, I am extremely concerned about the risk of a crash due to sudden loss of power. I am really concerned for my son and I as I drive my vehicle. I am requesting: 1. An immediate inspection and confirmation of eligibility for an engine replacement at no cost to me. 2. Verification of the lifetime long-block warranty extension associated with the KSDS (Campaign 966) update. 3. Provision of a loaner vehicle or rental reimbursement while my primary vehicle is unsafe to operate. Please assign a case manager to this matter and provide a timeline for resolution.

Motor locked up

My car has been stalling and shaking for months on acceleration. This has put me in unsafe situations where vehicles are going very fast on the highway and I am going 20 miles under the speed limit, or I am accelerating to merge and my car fails to accelerate, or I'm on the regular road and my car slows to a crawl while people are coming in fast behind me. The Error Code is: Cylinder 3 misfire. Took it to the dealer, they said they couldn't find anything wrong with it because the light was not on, they updated the software, as soon as I drove home the problem came back. They still charged me $200 for service, even thought the vehicle is under powertrain warranty which covers the cylinder block head and all internal parts. Online research shows this is a common problem in 2017 Hyundai Elantras. Many tried replacing coils and spark plugs only for the problem to return again a few months later. One successful fix found the computer needed to be replaced with a new one.

VEHICLE PASSENGER DOOR SUDDENLY BECAME UNABLE TO OPEN. MECHANIC SAID THIS IS A COMMON PROBLEM IN MANY MODELS AND YEARS OF HYUNDAIS.

The vehicle has been randomly shaking at idle since around 100,000 miles. There have now been a few instances where the engine will shake when decelerating. There are no warning lights, codes, or diagnostic readings that have given a solution for this. Around 145,000 miles the engine began to shake aggressively while driving, as I stopped and put the car in park the engine light, oil light, and battery light came on and then the entire system failed and the car shut off and could not be turned back on. This happened on a “highway” CA-108. I was stranded in the middle of the road, during school traffic hours. I towed the car to the dealership where they said they couldn’t replicate the concern but replaced the oil control valve. It has been 2 months since the repair, the vehicle is again starting to shake when decelerating. I now pull over when this happens though it typically stops within 45 seconds. I have seen the other Elantra engine recalls and feel as though mine fits the description.

RAPID LOSS OF POWER FAILURE OF IGNITION COIL. HAPPENED FOR ALL FOUR. SUDDENLY UNABLE TO OPEN FRONT OR REAR DOORS ON PASSENGER SIDE. ACTUATOR FAILURES. BOTH OF THESE CONDITIONS REPORTED TO HYUNDAI, MY COMPLAINT IS THAT HYUNDAI IS WELL AWARE OF THESE PPROBLEMS DEALER CONFIRMED THEY ARE COMMON ACROSS MODELS. THEY ARE EXPENSIVE REPAIRS. WHY ARE THEY NOT RECALLS. COILS HAPPENED ABOUT 2023 WITH 55000 MILES (OUT OF WARRANTY). DOORS ARE CURRENT AND I CANT AFFORD $2000 FOR REPAIR.

IN FRONT OF VEHICLE THERE ARE SIDE MARKER PARK LIGHTS AND IN CENTER THERE ARE 2 PARK LIGHT TURN SIGNAL COMBINATIONS. DRIVERS SIDE PARK LAMP IN CENTER WORKS PASSENGER SIDE DOES NOT INSIDE HEADLIGHT ASSEMBLY ON PASSENGER SIDE THERE IS NOT A POWER FEED WIRE ON ORIGINAL OR REPLACEMENT FOR THE PARK LIGHT CIRCUIT. DRIVERS SIDE DOES HAVE THIS WIRE.

Component or System Involved Engine and internal lubrication system. The engine and related components are available for inspection upon request. Description of the Problem In January 2025, this vehicle experienced a catastrophic engine failure and seized. An independent repair facility inspected the engine and reported metal fragments in the engine oil, indicating internal engine damage. The vehicle was then transferred to a Hyundai-authorized dealership for major engine repairs, which were completed on January 18, 2025. Less than one year later, the vehicle developed excessive oil consumption. In October 2025, the engine stalled and was found to have no oil, despite having received an oil change approximately one month earlier. The vehicle is currently undergoing Phase 2 of Hyundai’s oil consumption testing. The dealership has indicated a full engine replacement will likely be required. Oil consumption has been measured at approximately 1.5 quarts per 1,000 miles. This vehicle is not currently included in Hyundai’s engine recall or warranty extension, despite being the same make, model, and model year as vehicles that are covered and exhibiting the same failure characteristics. Hyundai and NHTSA have documented similar engine defects on other Elantra models due to piston oil ring issues, resulting in excessive oil consumption and engine failure. My vehicle exhibits the same symptoms and failure mode. Safety Risk Excessive oil loss can result in sudden engine stalling or seizure without warning, creating a risk of loss of propulsion while driving, including at highway speeds. Confirmation or Reproduction of the Problem The failure has been confirmed by an independent repair facility and by a Hyundai-authorized dealership through inspection and ongoing oil consumption testing. Inspections by Others The vehicle has been inspected by both an independent repair facility and a Hyundai-authorized dealership.

Air bag light will not turn off so I’m not sure if the air bags work. Oil is going missing from the car causing it to suddenly shut down. It also makes the rpm’s go really high (close to 5,000) when trying to go up hills or accelerate. I don’t see a leak, or puddles under the car, nor black smoke.

My 2017 Elantra with 107,000 miles (it has a 100,000 mile powertrain warranty) on it has just experienced the same issue as all of the other Hyundais that have been recalled. I was driving on Xmas evening 2024 and started hearing my engine making noises I had not heard before when excellerating but then they would go away. On my way home the check engine light went on for a couple of minutes but then went off and I was able to get home although the car did not seem to be riding well. The next day, the check engine light went on again and so I brought it in to my mechanic. He said that there were metal fragments/shavings in my oil that were clogging my engine, etc. He said that I need a new engine and said he had several other Elantras with the same issue and that I should take it to a Hyundai dealer because of all of their recalls/Class Action Lawsuits which extend warrantees, etc. for the same exact issue. I was able to drive the car there but it was not a safe drive. Their assessment was basically that I need most of my powertrain replaced to the tune of $4100.00 but once they get in there, it might be more extensive and end up having to be replaced. However, they did not say anything about the metal fragments and when I brought it up to them, they acted like they didn't see them. However, my mechanic (with no skin in the game) said they were all over the place in my car's oil. So, I am a little wary that they decided to skate that issue, since it is the basis for all of their Class Actions, etc. I'm kind of stuck, Hyundai has my car and it really isn't drivable. I've checked many Elantra forums and have seen that this is happening to Many other 2017 Hyundi Elantra SE even though they have not yet been added to the recalls/Class Actions, etc. I really think that the Hyundai engine issue is more widespread than just the cars on the current list and I hope that this is looked into as it is extremely dangerous and comes on very quickly without warning.

Power windows stop working, car cuts off, heated seats stop working intermittently

The door locks are faulty and do not allow the door to open. This is the second time the vehicle has had issues with the doors not unlocking. The first time it was my front passenger side a few years ago and I paid an auto shop to repair it as this was an immediate safety concern in case of a car accident or fire. A few months later Hyundai issues a recall and sent me an email about the faulty door locks and that they could be repaired at a Hyundai. I called to ask for reimbursement since I paid out of pocket and they refused. Now another door lock is broken, this time the rear driver side, and I have the same safety concerns as before since the door does not open from the inside or outside. In both cases, the issue was sudden and no other damage occurred to the vehicle. It's unsafe to have to drive with doors that cannot unlock from either inside or outside.

Ignition coil failure. Causing misfires and rough idle. Misfire initially found in cylinder 2 when check engine light illuminated and check with an OBD II reader. Swapped the cylinder 1 ignition coil with cylinder 2. Check engine light returned the next day with the same signs. Check engine light and rough idle. OND II code scanner now says misfire in cylinder 1. The rough idle makes for slow acceleration until above 20mph.

Car was constantly losing power, called Hyundai dealer about the OBI system thinking that could be the cause they told me no, and then in 2 years ago the car started stalling when you slowed down and on the way home from work it completely died. Car still turns over but car will not go, engine and transmission are completely done. It’s been at my house sitting since. Hyundai dealer is a joke a wouldn’t help when the issue first arised.

My alarm keeps going off and car won’t start

The contact owns a 2017 Hyundai Elantra. The contact stated while driving 60 MPH, the vehicle stalled. The contact was able to veer to the side of the road. The check engine warning light was illuminated. The vehicle failed to restart and was towed to an independent mechanic, where the contact was informed that the engine pin in the crankshaft might have failed. The mechanic informed the contact that the engine needed to be taken apart for a definitive diagnostic test. The dealer was notified of the failure and informed the contact that the VIN was not under recall. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 88,000.

November 1st, 2024 My husband and I were northbound on I71/75 at mile marker 160 while traveling in the high speed lane, doing 65 mph, when the car suddenly lost power, the check engine light immediately came on (NO prior) warnings. The car would not respond, had to coast to the side of road while traffic is whizzing past us at 65+ mph. The car at that point was DOA, lights would come on but motor would not respond . After many discussions with Hyundai corporate and sending them proof of eligibility for remaining factory warranty (window sticker information) that I was told in detail by the dealership representative. I was told emphatically that with it being a lease turn in that I was still eligible for all remaining warranties. Hyundai corporate says that even though I only have 88,000 ( odometer reading at purchase was 24,147) of a 10year/100,000 warranty on the engine. Hyundai corporate says that because I wasn't the original purchased that the warranty is null and void. I feel like there is something very wrong here when these warranties can be voided at the whim of the manufacturer. I have since had to purchase another vehicle in order to make it to the VA medical center for my husband and make it to the hospital for my cancer treatments.

Front doors won't open from outside.

Was driving my car noticed that it was running a little rough and took it in for an oil change thinking maybe it was being a little weird because of that. I religious have my oil changed routinely. The gentleman changing my oil told me there was oil in the engine. Went to Hyundai and they did a diagnostics and told me that something had come off in the engine and clocked the oil gallery not allowing oil to flow through engine and power train. Was told it would be a $9000 engine replacement. I only have 93000 thousand miles on it still owe 3000 on it. Hyundai knows that their engines have been having issues. Salesman at Hyundai was trying to force me to buy a new car because of this issue. he was only going to give me 2500 on my car but told me if it had been in perfect condition then he would've 6000. This is not something I did to my engine it was something that came off in the engine and blocked the flow of oil

The oil level burns down to next to nothing approximately every 2 months, with no oil light warning or engine light. However, the engine light does periodically come on but shuts down itself before able to get it checked. The same issues occured with my son's 2017 hyundai which caused the engine to blow and catch fire. His was recalled and repaired. His was a different model. The oil burn on my car has occurred at least 3 times. The steering feels as though it is grinding at lower speeds an makes parking difficult as well. Both of these issues are most concerning.

Driving 55 miles an hour on [XXX] engine shut off and seized I filed a complaint with Hyundai corporation Claim number [XXX] They said they were going to make a decision October 25th still didn't hear anything called them back now they said October 30th The vehicle is sitting at Webb Hyundai Merrillville Indiana.

The rear door no longer open and the front doors need to be tugged several times before opening. This is a huge safety problem and I’ve seen many others with my type of vehicle and year with the same problem. The actual door problem is unknown. I just know they will not open and it all happened at once. I haven’t gotten into an accident or no force to prevent the door from opening has not happened. So I’m not sure of the actual problem.

When my car was stolen and crashed the whole front end was smashed in but the air bags did deploy. I saw there's several recalls on these cars, one was the airbags. I never got any recall for it and it shows there are no recalls. The brakes have problems, being that it takes forever to slow down. I have to leave about 3 car lengths ahead of me because I can't stop, it takes a while to slow it down. And the steering wheel feels stuck. I had a friend drive it and he said the same thing. It's difficult to handle and not lose control. I'm to the place I'm scared to get on the highway anymore because not being able to stop quickly and swerving all over cause it's hard to control the vehicle. I have had zero recalls tho even with me experiencing this. And the paint is coming off, but at least that won't kill me.

All four engine coils blew before 60,000 miles. The car was being used and maintained properly and there were no associated engine or spark plug defects noted. However, all four original engine coils failed and had to be replaced.

Loosing power steering assist while driving.

Hyundai claims its engines have a 100,000-mile warranty, but my Elantra 2017 engine blew up/ broke down just after 890200. Therefore, I called the Hyundai corporate office to fix my car. I also approached local Hyundai dealers at Jaining Road Hartford, Connecticut, but they refused to resolve my problem and denied replacing my car engine. I have no choice but to fix my car. I filed my complaint to Hyundai case no. [XXX], but Hyundai is not ready to resolve this issue. I have spent $4000.00 from my pocket to put my car on the road. I am requesting for the reimbursement. I have all the repaired bills and invoices. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2017 Hyundai Elantra SE sedan. Car starting stalling around turns and the next day engine had rattle and loud noises coming from engine. No lights to indicate problems prior to stalling out or engine issues.

My steering wheel locks up on me and the my check engine light flashes on as it does. I also have a steering wheel light with an explanation point beside it flashes when and before my steering wheel locks up! I can be sitting at a red light and my steering wheel locks up on me. My traction control light is also on and will not turn off. It turned on when my steering wheel locked up and my steering wheel icon came on.

The car engine is consuming too much oil causing the oil to run out of the car too soon. The car engine starts knocking & the car keeps cutting off.

I was told by the mechanic about the following. My car has shown engine oil burning issue, and it made the timing chain placing in the faulty function frequently. I changed the timing chain last year and was advised that I would need to check engine oil level because of engine oil burning issue. I was advised to check it at every 2500 miles. Recently my car showed check engine light on again, so I visited the repair shop and found out that the engine oil was totally gone before 2000 miles. The synthetic engine oil change should be at every 5000 miles. The rapid engine oil consumption made my car getting check engine sign on and I was told that it eventually would stop my car. And I was told that it is very hard to fix it because it is due to faulty engine issue.

Altimax RT43 205/55R16 The sidewall in the front passenger side tire has developed a very significant bulge. I have photos to confirm. I'm extremely concerned about an imminent blowout, regardless of speed, and the loss of control, significant damage to the front-right part of the car, wheel rim, and potentially causing accidents with other drivers. It hasn't yet been verified both 3rd parties (insurance, manufacturer, etc). I noticed it approximately 8/28/24 when a low-tire-pressure indicator came on on my dash. The tread is in good condition, and the tires have less than 20,000 miles on them.

The vehicle has about 136,000 miles and was driving when the engine just started knocking. There were no engine warning lights or any other indications there might be an issue. We Towed the vehicle to the dealer, and they advised that it needs a new engine. We are the original owners and maintained the vehicle with regular service and oil changes.

The engine failed without warning! The car stalled and could not be started again. There were no warning lights or indicators that the engine was having problems. The car had fresh oil and luckily I was just completing the safety check after an oil change. Had I been on the road, this could've been dangerous. The Hyundai dealership noted a seized engine with no further explanation without an extra $1000 charge. It will cost $10,000 to replace the engine that was well taken care of and only had 106, 748 miles on it.

Power steering is loose or tight. It turns off while driving. Clunky sounds when it's working.

Doors are locking up for what reason I don't know. This is a safety problem and the dealership wants to charge me for their problems with the car.The maker of this know what the is , but charging 1500 dollars to correct their problem with these doors.

The cars just stops running as you are driving. It's happened multiple times. We've changed the crankshaft sensor & cleaned the fuel system. We saw these remedies online as multiple people are having this same problem with their Hyundai.

I've heard that 2017 Hyundai Engines have had some recalls and looking online at others with these vehicles also experiencing same problems. Car only has 82,000 miles and now cutting off in the middle of driving under 1500 RPMs also shaking until it cuts off. Seems these cars engine warranty should cover the attached repairs as we've always done excellent service on these vehicles. I'm trying to see if there is anything I can do as we now have a $3500 repair and have to get a rental car in order to get to work.

While driving on three occasions I was driving and my car completely shut off where I had to pull over once to restart the car. The other two times I was on the freeway and had to put the car in neutral and restart the car. I almost got hit both times on the freeway when this happened.

When car is unlocked the drivers door will not open until you pull 3 times. Now the passenger door will not open at all from the outside. You have to open door inside car and push door open.

Have a raw fuel smell every time I park my car

I'm having issues with my car and I don't feel safe riding in it. While driving it start to coast. If I make a turn it shuts down. I am having some of the same issues some elantra having but because the VIN# doesn't show a recall I'm penalize for having this car.

The contact owns a 2017 Hyundai Elantra. The contact stated while coming to a stop sign, there was a failure with the brake pedal. The contact was unable to depress the brake and instead engaged the parking brake to stop the vehicle. There was no warning light illuminated. The vehicle was taken to the dealer however, the vehicle was not diagnosed or repaired. The dealer stated that after the vehicle was inspected, there were no failures found with the braking system. The contact stated that the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 52,900.

Our Hyundai Elantra Se 2017, engine blown. Started with knocking sound and when we stopped on the side of the highway it powered down. We have been told that unfortunately so many of hyundai's vehicle engines have been super problematic within the last decade. We were stranded on vacation. Had to pay for towing twice and a rental car to get back to North Carolina because we had to get back to work. We also have had to pay to diagnose the vehicle twice. We had the issue diagnosed with an independent service center Tuffys Auto in St. Johns Florida and now it currently is at Hyundai in St. Augustine. We have been without our vehicle for over a month and with the trending problems with these engines we shouldnt have to come out of pocket to fix it. Hyundai corporate has not been helpful at all even though we have had a case manager for over a month and they havent given us any info.

Safety concern is that the car lost power without warning while driving on 4 lane highway. My son was attempting to pass another vehicle and he noticed the hyundai was not accelerating with his foot on gas pedal. he had to coast back across the lanes of traffic to avoid being hit. Confirmed issue:The car had to be towed and Hyundai dealer states the vehicle needs a new engine. Vehicle has been inspected by Hyundai dealer no warning signs at all

The engine of my vehicle malfunctioned. It is available for inspection upon request, it will have to be towed. The problem put myself and others in danger as the car stopped as I was driving in the middle of a 3-lane highway in the far left lane. Others were put in danger as they had to swerve to avoid hitting me. That itself could have caused a chain collision as other vehicles in the middle lane were put in danger. I was also at risk to get rear ended as one might not notice that my speed has stopped increasing. I have already had it towed to a local Hyundai dealership and auto shop; both said it needs a new engine. Towing receipt is shown below. I had no warning lights on my dash prior to the engine failure. A battery light and check engine light appeared after I was able to safely pull to the side of the road and try to start the car again.

My 2017 Hyundai Elentra Sport engine failed with 127,000 miles on it. Hyundai had a class action lawsuit for many models that guaranteed engine replacement and extended the life of the warranty to 15 years/150,000 miles. Unfortunately, it is the same issue with my model. Oil consumption issues resulting in a Blown piston. Oil was changed a week prior. Preston Hyundai confirmed that it was a Rod failure in the second piston. Paid the diagnostic fee and they put in a “Good Will claim and it was denied within 30 minutes. Preston Hyundai still has not sent me a receipt detailing their diagnostic or a copy of the goodwill claim after multiple requests. I want the record of this because the class action lawsuit that ended up protecting owners many years later
