NHTSA Safety Complaint â 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…

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…

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…

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 manufacturerâs 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…

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.

I had bought my car in May of 2025 and within 12 hours of owning it. The check engine light came on. They replaced the sensor well. A couple days later, the check engine light came on again, and they had to rebuild my whole engine had the car for a month at this time. When they rebuilt the engine, they had the car for over a month. And ever since I got it back, it's always something the same thing has to get repaired. Well, I took it to the shop. Yesterday because it was misfiring, and I needed to have some spark plugs replaced, and they said that the Ignition coil needed to be replaced, but there was a recall on that not too long ago. And they fixed that on the recall. There's no reason…
