I bought this car from someone recently and was unaware of the engine recall, I did checking and found that there's a recall on the engine, it's knocking, can't be driven, it has 128,000 miles on odometer, does the recall expire because I read that they never expire, I love the car and would really like to have it repaired.

THANK GOD I DIDNT GET HIT Didn't get the chance to pull over the car just shut off. The whole car died I had to have it towed way I tried changing 12 V battery to a brand new one still didn't work. I've had it towed to hyundai dealer. What is wrong with this car? Still don't kno this happened in september of 2022 took it 2 different Hyundai dealerships. As I've been researching this is happening to a lot of people. With the same make a model car. I talk to corporate. They can't help me with anything because it's over a 150000 miles. You would think that they would help with some of the cause being the fact that is happening to all of the hybrid cars

On 04/25/2023 while driving to work my car all of a sudden started flashing -??check engine light-??. The flashing was continuous and my car lost almost all power and would not go above 2 rpm. It was terrifying. I immediately notified Hyundai and had my car towed to dealership. Now Hyundai is telling me I can-??t get rental reimbursement until they approve and engine replacement, which can take up 2 months.

After intermittent starting and car dying for no reason, the engine completely died while driving on highway. I filed a claim with Hyundai as part of Theta Engine settlement. I had the engine replaced at my expense, they will not cover. It is now burning oil at an alarming rate. This is dangerous and has happened to many many HYUNDAI/KIA owners as part of this engine problem.

As i was getting off the interstate, my car literally shut off completely, no warning signs or anything, so my fiance thought it was the alternator, went to get a new alternator, & my car still didnt crank, got a new starter, my car still didnt crank. So i had to tow it to an independent service center and he determined that my motor had seized. Which was weird because i kept my car up. My safety was put at risk because i could have had a wreck getting off the highway with cars coming down a ramp.

Hello, I am the second owner of this car since 6+ years. I had given the car for fluid flush as part of regular service at a local Firestone. The technician was on a test drive after service and the engine hydrolocked. I have been without a car since last 5 days and no one seems to take the responsibility and help me with replacing the defective engine as it has major known issues with engine. Please review and help. Thank you. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I was driving my car at approximately 45 MPH when my car began smoking and overheating and making a knocking sound from the engine. I pulled over and checked but had coolant in the vehicle as I had just got my car serviced 3 weeks prior. I was about to get onto the highway when my car decelerated and the oil lamp and engine light started flickering as my car lost power and started smoking profusely.

Engine suddenly shutdown while driving in the middle of the road. Luckily, I was not on the highway. Had it towed to my mechanic and he told me that there was a class action lawsuit on these engines and that they were known to fail after 100,000 miles. I never got any notification about this problem. I am checking with the Hyundai dealership about replacing the engine.

3 Months post oil change June 2022, oil plug fell out on highway and motor seized. Dealership advised motor no longer manufactured and recommended used motor supplier. Purchased a used motor with 80K on engine, had it installed in June of 2022. Dealership did oil change in December 2022, in February 2023 noticed oil smell and oil on the ground in driveway. Added 4.25 quarts of oil and started motor, attempted to locate the leak when noticed leak below motor. Turned off motor and found oil dripping from under car near the oil drain plug. Reached under car and touched oil drain plug with finger and plug fell out draining all oil to the ground. Had vehicle towed to the dealership, new oil change completed. Demanded the dealership install new oil drain plug, torque to manufacture specifications and apply lock tight to plug. Dealership stated they no longer remove the oil drain plug due to customer complaints and stated they only pump out the oil. When i asked them if that was a manufacture recommendation or their own they stated they started doing it due to multiple complaints from customers. Two engines 8 months apart, oil drain plug coming lose and falling out not a coincidence.

gasoline engine. yes, it is available. This vehicle has broken down and left me stranded at the side of the road more than a few times. It has failed on the Interstates, as well as local highways. The dealer refuses to replace the faulty engine. No warning lights have come on with regard to the gasoline engine. Ever since I purchased the vehicle, it sounds like there are marbles in the gas engine when its running at low rpm. The oil leaks are extreme and getting worse. It is smoking badly. I just do not have any more money to pour into this vehicle. I want a new engine from Hyundai.
