2018 Hyundai Tucson

The oil fuel tank has been burning oil too fast in the GDI Engine & the oil has burnt through my alternator and spark plugs that I recently fixed only three weeks ago. This caused the engine to lock up completely while I was driving several times & I lost control while driving - having to restart the car multiple times to move it to a safe area. Now, the engine has locked permanently and I am unable to start the car at all despite replacing several parts and getting an oil change every 3-5000 miles (which continues to leak too quickly and harm other parts in the car).

Knock sensor recall was done in May 2022. Brought vehicle into service for Ac problem and oil change, which was completed. Was on highway going home 65 mph speed limit hit a hill, my engine light started flashing, my transmission downshifted and I lost all accelaration while on hill, speed wouldn’t go any higher then 50 at that point. Got to closest gas station and had car towed back to dealership, I just want to point out that the knock sensor is going to put people in danger in certain situations like myself, I am not to happy.

The engine caught on fire, it was considered totaled loss. I settled with the insurance and not sure if the car is still available for inspection. My safety was put at risk because I was driving the car when it happened. I did not get injured because I was able to get out of the car. There was no recall from what I know. The car was inspected by GEICO which is why it was considered totaled loss. There was no warning before the fire. The car was in great condition.

ENGINE LIGHTS continues to turn on every other day or so I took my car to get its regular Oil change and expressed this to one of the service reps about this issue they told me They couldn’t do anything about it because once they turned on the vehicle the light came off. A few days ago my engine started Blinking and I started panicking since I was on a highway from a road trip my car started making this awful cackling noise and I had To call a tow to then get told That this can take WEEKS TO FIX and NO RENTALS CAN BE PROVIDED WHEN I AM CLEARLY IN A DIFFERENT STATE THEN WHERE I LIVE! Hyundai IS ONCE OF THE WORST AUTO I HAVE EVER DELT WITH! Absolutely not Help I was practically stranded on an issue that Had nothing to do with me! The engine light came Out of no where

Aug 9, 2022 ~1pm. Driving ~60 mph south on highway 18, 30 miles north of Lusk, WY. Heard 30 seconds of slapping noise from engine, follow by oil pressure low light. Accelerator also ceased to function. Pulled to side of road and waited for tow. Towed to Ken Garff Hyundai in Cheyanne, WY. Inspected on Aug 25, 2022 by technician at Ken Garff two weeks after incident. Hyundai authorized engine replacement. Hyundai also stated twice that there was a recall on the car. No recall appears in the NHTSA database. Problem is very similar to Part 573 Safety Recall Report 21V-727, which includes the 2017 Hyundai Tucson.

The vehicle has 81,000 miles with regular oil changes. We purchased as a certified pre owned with 45,000 miles on the vehicle. The car had been running perfectly. Last weekend the car was making an awful noise. Today the mechanic tells us the lower unit is knocking and the motor will need replaced. There is no way this should be happening at this mileage especially since the car has been regularly serviced. Hyundai is not even interested in repairing the vehicle, went straight to trying to get me to trade it in. We could have been stranded or killed on the highway and with all of the other complaints about this motor, I can’t believe there hasn’t been a recall.
