Hyundai Motor America (Hyundai) recalled certain 2019-2021 Tucson vehicles on September 4, 2020. On December 30, 2020, Hyundai expanded the recall population, and added certain 2016-2018 Tucson vehicles. The Anti-lock Brake Hydraulic Electronic Control Unit (HECU) could corrode internally and cause an electrical short, possibly resulting in an engine compartment fire.
NHTSA Safety Complaint – 2019 Hyundai Tucson Engine Failure I am reporting a serious engine safety concern involving my 2019 Hyundai Tucson AWD 2.0L (VIN: [XXX]). On XXX, the red engine oil-pressure warning light suddenly illuminated while I was preparing to drive home. Concerned about possible engine failure, I stopped using the vehicle and had it towed to Pohanka Hyundai in [XXX]. On XXX, the dealership provided a diagnostic video indicating that the engine was defective and needed replacement. A written estimate dated XXX quoted $7,823.58 for an engine replacement. Despite this diagnosis, the dealership later declared the vehicle drivable and returned it after adding oil, without providing a satisfactory explanation for reversing its original findings. The engine problems continued, and the vehicle had to be returned to the dealership. This presents a serious potential safety hazard. An unresolved engine or oil-pressure problem could cause sudden engine failure, loss of propulsion, or a breakdown while driving on a highway or in heavy traffic, increasing the risk of a collision and injuries to occupants and other motorists. I am particularly concerned that a vehicle initially diagnosed as needing engine replacement was subsequently declared safe to drive without documented evidence that the underlying problem had been corrected. I request that NHTSA investigate whether this engine failure represents a broader safety defect affecting 2019 Hyundai Tucson vehicles and whether additional safety measures, including a recall investigation, are warranted. Vehicle: 2019 Hyundai Tucson AWD 2.0L VIN: [XXX] Mileage at diagnosis: Approximately 87,656 miles Incident Date: XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the highway 65 mph in our 2019 Hyundai Tucson AWD, the vehicle suddenly experienced a severe power loss, loud engine knocking, engine light flashing, and the car in limp mode. This caused a terrifying hazard. We exited to safety, the car was towed and is at a Hyundai dealership. It pulled a diagnostic engine trouble code P1326 (Knock Sensor Detection System). The dealership confirmed the code, but is refusing to replace the engine under the Hyundai Engine II Class Action Settlement without an out-of-pocket 'combustion cleaning' fee, which, as seniors, we cannot afford on a fixed income. The dealership service manager told us that he requested Goodwill from Hyundai Corporate for the combustion engine cleaning. And because of a past denial, corporate denied it a 2nd time. So, we contacted our Hyundai Corporate case manager, who said our request for “the engine replacement” was still pending and in review by their team. She saw no denials, except for a loaner, which would be approved, upon repair approval. We added the dealership service manager on this call to discuss confusion about goodwill be denied by Corporate for the “combustion cleaning”. He said this case manager would not see the combustion cleaning requirement, because it was instructed by another department. His then pivoted the topic & said we received an estimate for combustion cleaning. My response “we never received an estimate & have no estimate in my email”. His response “I hate to use this word, but you’re a liar”. My husband then took the call saying “we did not receive an estimate in writing, although we had asked the tech for an estimate but nothing was final.” The service manager cut him off and said “we are done come pick up your car” & hung up. This dealership phone interaction needed to be included in this incident because now we are being put in grave danger as he is expecting us to pick up our un-drivable, unsafe & hazardous car with no concern for safety.

While driving at highway speeds, my 2019 Hyundai Tucson SE suddenly loses acceleration and drops into a 30 mph 'limp mode' while the engine overheats. This creates an immediate highway safety hazard with an imminent risk of a rear-end collision. The vehicle also suffers from excessive oil consumption, requiring manual top-offs twice a week. The servicing dealership diagnosed a fuel system failure, quoting $5,847 to replace the fuel pump, fuel injectors, and oil gasket. Hyundai Corporate (Case #43358088) officially denied warranty coverage on October 12, 2026, falsely claiming wear and tear despite active TXXM 150,000-mile extended warranty framework protections. Furthermore, there is a data discrepancy: the dealership pulled diagnostic trouble code P0172, but corporate claims the vehicle threw code P0173 and is withholding the physical diagnostic printout behind a fee paywall.

I have had 2 catalytic converters the original and a 2nd one. Now I need a 3rd due to excessive oil consumption. Corporate did a good will for a combustion cleaning and that did nothing. The dealership checked my oil and said there was excessive oil consumption and submitted for an engine replacement and it was rejected. Absolutely ridiculous.

The new 2019 Hyundai Tucson equipped with the Nu2.0L GDI engine, I purchased in 1/2020 as the original owner to this day has been diagnosed with a burnt exhaust valve due to heavy oil consumption that has been an uncorrected documented manufacturer’s defect within Hyundai motor corporation. The excessive engine oil consumption has poisoned and destroyed the first catalytic converter, has fouled the combustion chamber which has consequently choked and burnt the exhaust valve with the excess oil ash and carbon buildup. The car was approved for a second catalytic converter install last week which my car currently sits at 125,000 miles and the dealership through the authority of approval with Hyundai motor America has replaced under warranty however subsequently running the excess consumption test, the car now has a burnt exhaust valve which Hyundai motor America is extending a “good faith” proposal which they are willing to replace 60% of the burnt valve and I’m responsible for the 40% even though I have complied fully with the dealership’s recommended preventive maintenance schedule which has been solely performed at the same dealership since the day I bought the car and drove off the lot up until the 100K mile warranty. And now discovering my particular motor has been extended to the 15/150,000 warranty due to the lawsuit settlement. I have continued with my diligence with keeping up with the oil, instead of ignoring the issue that the car burns excessive oil to potentially has the engine fail while driving to be fully covered on the rod bearing failure settlement. Help in my concerns would be greatly appreciated through NHTSA.
