2019 Hyundai Tucson Engine Problems

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly stalled and was idling roughly. The message “Stop Driving” was displayed. The contact stated that the vehicle failed to accelerate and lost automotive power. The failure had occurred several times. On one occasion, the vehicle had to be towed. The vehicle was able to restart after several failures. The vehicle was taken to the dealer, where it was diagnosed with engine failure due to excessive oil consumption. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 59,000.

While driving at highway speed, the engine suffered a sudden connecting rod bearing failure (Cylinder 3) with no prior warning lamps, messages, or symptoms. The vehicle made a slapping noise, a belt came off, the engine died, and would not restart. The vehicle was towed to an authorized Hyundai dealership. The driver, a [XXX] [XXX] , was able to safely guide the vehicle to a stop without injury. The dealership inspected the engine and confirmed a complete Cylinder 3 connecting rod bearing failure. The technician contacted Hyundai Techline, who confirmed the diagnosis and recommended engine replacement. The estimated repair cost is 6,500. The failed engine is available for inspection at the dealership. This vehicle is a 2019 Tucson with the Nu 2.0L GDI engine, which is covered under the E2 Class Action Settlement for connecting rod bearing defects. Hyundai Service Campaign 966 provides a KSDS software update designed to detect abnormal bearing noise before catastrophic failure occurs. This update was never performed on the vehicle. The 2019 Tucson was not added to Campaign 966 until April 2022, after the vehicle had already been purchased used. The owner was never effectively notified of the campaign and the vehicle was never at a Hyundai dealership where the update could have been performed. Hyundai denied warranty coverage solely because Campaign 966 was not completed, despite confirming the failure is the exact defect type the campaign and settlement were designed to address. The vehicle had only 49,437 miles at the time of failure. The engine failed without any prior warning — the exact scenario Campaign 966 was designed to prevent.

The vehicle has had two catalytic converters replaced in 70,000 miles

Oil extremely hot and burnt to oil stick. Running really hot. Dangerous possible fire hazard

Low oil, burnt oil on dip stick, engine running dangerous hot, lights on on dash, engine knocking

The vehicle has consumed the oil and no light came on. I drove and i checked when the running engine start doing a dry noise and loose the power. The stick was completely dry, i filled with 2 litters and now the stick show in the half. My vehicle has 60k miles and tomorrow will check on the servis. It is unacceptable first how the vehicle consumed the oil and the second the system didn't notify risking an overheat and posing an elevated risk to spop in the middle of the road causing an accident or starting a fire due to overheat.

Purchased this car used 3 years ago. Followed owner's manual for oil and filter changes. On 1/2/26 the engine seized, had it towed to Hyundai dealership and they will not approve a replacement for the engine because they said I hadn't followed maintenance guidelines. I submitted all receipts and they still are denying. I had the KSDS and all Hyundai campaigns addressed which was to extend the warranty and they still deny. NO WARNING LIGHTS whatsoever came on until the engine seized on the parkway. Hyundai knows there is an issue with these engines but still won't step up.

Hello, my 2019 Hyundai Tuscan I have owned for 3 years-4 years. Unfortunately it is a GDI Motor, it uses oil so bad, even though I do change the oil every 3,000 miles, and do every maintenance on the vehicle that is told to me done, ever time I change the oil it is low, even though I top it off through out the 3,000 miles. I have no leaks at all and it is just evaporating, I do not think this is right for a 2019… there is several issues and concerns from other buyers with this issue. There should be a fix to this, asap

Oil component failure causing extreme heating within the engine and catalytic converter which poses risk for engine fire. This oil consumption issue was addressed by the dealership who ran a test to see how much oil was consumed. The test results showed that the vehicle was burning oil at a high rate and would ultimately result in engine failure. The low-oil light has never come on indicating a need for an oil change. Despite this, I have constantly pulled my own dip stick and got changes every 2,000 miles. For this make and model, they required a change every 5,000 miles. When I notified Hyundai Corporate over this concern. They claimed due to it being outside of warranty, that it does not matter what my engine light has been doing since I got the car, nor the issue with the oil consumption, they refuse to address any of these problems as being a manufacturing problem. The maintenence has been kept up since I got the car, so the manufacturer is not acknowledging the constant issue with Hyundai Tuscon engine dangers. If a fire were to occurr, I was told this is not Hyundai's responsibility due to me not being the first owner and it not falling within warranty. After the combustion test, Hyundai claimed that they refilled my oil. When I checked my dip stick after only driving 100 miles, the image attached will show the resulting levels. My oil light is still not coming on despite this. Even when it has been much lower than the pictured level. This, paired with the super heated catalytic converter due to the oil consumption, is going to cause an engine fire and is not fair to the consumer.

My 2019 Hyundai Tucson, VIN [XXX] , has developed engine knocking, which may indicate internal engine failure. A mechanic has suggested a possible loss of cylinder compression, though the exact cause has not been confirmed. Hyundai vehicles from similar model years have experienced engine failures related to bearing wear and metal debris, leading to stalling, loss of power, and complete engine failure. These failures present a serious safety risk, particularly if the engine fails while driving. I am concerned that this defect could result in sudden loss of power or engine seizure, increasing the risk of an accident. I am submitting this complaint to ensure the issue is properly investigated and addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2019 Hyundai Tucson previously required an engine replacement due to a known defect. After the engine replacement, the check engine light remained on. Recently, the check engine light began flashing, and the vehicle was towed to the dealership. I was informed the vehicle has a radiator/cooling system failure. Given the history of engine defects and warning lights, I am concerned about vehicle safety and reliability.

The engine has begun making a persistent knocking sound, especially during acceleration. A mechanic inspected it and indicated it may be related to cylinder compression issues or internal engine damage, but the exact cause is not yet confirmed. Because this matches symptoms associated with the known connecting rod bearing defect affecting the 2.0L Nu GDI engines, I am requesting a full warranty inspection under the Engine II Settlement and Hyundai’s extended engine warranty program.

[XXX] [XXX] [XXX] [XXX] Vehicle Information: • VIN: [XXX] • Year: 2019 • Make: Hyundai • Model: Tucson • Mileage: 132,303 Problem Description: On Oct 11, 2025, my 2019 Hyundai Tucson entered limp mode on the freeway, losing power suddenly, posing a safety risk. This followed a dealership visit a couple months ago for a recall engine repair (possibly 21V-727). They returned the car with a check engine light, claiming it was a false error needing a reset on my next visit. No reset was done. On Oct 11, the limp mode forced a tow back to the dealership. They now demand $300 for diagnostics and refuse a loaner, claiming it may not be warranty-related. I’ve escalated to Hyundai national team case number : 41621677 with no resolution after four days. This feels like a safety defect tied to the prior recall work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On October 11, 2025, I discovered that my 2019 Tucson had no engine oil. I put three quarts of oil in at that time. Fast forward two weeks, October 25, 2025, and the dipstick read dry again, prompting more oil to be required. Unfortunately, I'm passed the 30 day warranty with the dealership I purchased the vehicle from so now this burden has fallen on my shoulders.

Oil consumption

Car is burning oil quickly. Had 2 oil changes within 3 months. Way before it was needed. No oil leaks detected. Oil gets dark fast and is burning off quickly. Take to Pep Boyz and other repair shops. Not yet taken to dealership.

My engine has an oil consumption problem that I've been dealing with Hyundai on. The vehicle is a 2019 Hyundai tucson. Last Friday [XXX] my car lost power on the freeway on a bridge and I began to slow down and couldn't pull over due to no shoulder. I had myself and my family in the car with me, (wife, [XXX] , [XXX] ) My car has failed two oil consumption tests and had a combustion chamber cleaning to try to resolve this issue. Now after losing power, the dealer has gone back on their word of engine replacement because Hyundai denied the claim. They are telling me the oil consumption lead to the catalytic converter getting plugged and losing power. The engine light for that has been on throughout all of the oil consumption testing (months) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car has had an oil consumption problem for over a year that Hyundai refuses to acknowledge. I passed the oil consumption test because the oil burns rapidly when I have about 1,000 miles left before my next oil change. They have replaced my exhaust, catalytic converter, spark plugs, and oil release valve over the course of many visits. Every time I have the oil problem, they find something different to “fix” and I have to pay out of pocket. None of these have fixed the actual problem. The hyundai representative I have been in contact with (after they reassigned my case to someone 3 different times - so it’s never the same person that is familiar with my case), told me there is nothing they can do to help me because the dealerships are independently owned. I am now out of warranty, although I originally brought my car there while it was still covered under warranty.

I am submitting this complaint regarding excessive and abnormal oil consumption in my 2019 Hyundai Tucson. Despite regular maintenance and oil changes performed according to manufacturer recommendations, my vehicle consumes oil at an excessive rate, requiring frequent oil top-offs between oil change intervals. I have experienced low oil levels with little to no warning, which poses a serious safety concern due to the risk of engine failure while driving. The vehicle does not show visible oil leaks, suggesting internal oil consumption. This issue appears to be consistent with numerous consumer complaints involving Hyundai vehicles of similar model years and engines. The dealerships have been unhelpful and dismissive, often stating that the oil consumption is “within normal limits” or requiring lengthy oil consumption tests without offering a permanent solution. I feel I am being given the runaround rather than receiving a meaningful repair or accountability for what appears to be a known defect. Excessive oil consumption can lead to engine damage, stalling, or sudden engine failure, which is a significant safety hazard for myself, passengers, and other drivers. Hyundai dealerships have failed to adequately address or correct the issue, despite the widespread nature of similar complaints and known engine issues associated with Hyundai vehicles. I am requesting that NHTSA investigate this matter further, as this defect affects vehicle safety and reliability and appears to be part of a broader pattern with Hyundai engines.
