Engine started making a noise and then the car died and would not start. We were on the highway service road when the car died in the middle of the road. We took the car to the dealership and they confirmed the vehicle engine has seized up. This is covered under warranty. The manufacturer denied the claim because of a sensor recall in August 9, 2018. We purchased this car used on July 11, 2018 and never received the recall notification for this sensor. The manufacturer is refusing to repair the engine that is under warranty.

The makes a weird shutter noise when accelerating and won't crank over 60. Loses power when turning or when going uphill. Sometimes has problem starting. Enging light came on twice blinking, once I changed the battery it went off and was working fine. Now it's back on again after a few weeks. Plus my oil tank still comes on and I've just received and oil change. I just bought the car in August of this year, dealership sold to me with a faulty battery.

My husband was driving the car on I95 yesterday, no lights on on the dashboard. Suddenly, the engine stalled and he had to pull out before it completely stopped. He could not get the car to start again. The only light on at that moment was a light indicating the key was not inside the car. He went home with a friend to get the other key, but it didn't started as well. The car spent the night at a shoulder on I95. This morning, he called an independent service center and after checking the car, they said the engine stalled because it run out of oil. There was no apparent leak and no lights indicating a problem with the engine oil. It was changed 2,000 miles ago only. The mechanic also mentioned that Hyundai had similar problems with other cars and that we should call them for that. Since there is no recall for the car, they wouldn't help at the dealer, unless we scheduled a service, which is available for April 21 only.

Had cruise control set for 75mph, and while traveling up hill, the car downshifted to maintain speed. After 10-15 seconds I noticed power loss and the check engine began to flash. Disengaged cruise control and pulled off onto the shoulder once I found a safe place to do so. As I was slowing down, there was a very noticeable misfire from the engine and was trying to stall out while still in motion. There was no knocking sound, nor was the car overheating. Once I was fully stopped, the car died and would not start back. Had the car towed back to my house. Replaced spark plugs because cylinders 2 and 4 were not firing properly. Also rotated coil packs around to see if they were failing. Cleared check engine codes but they immediately came back to misfires on cylinders 2 and 4. Did compression tests and found that cylinder 2 had 0psi and cylinder 4 had 20psi. Car was not low on oil and no other warning lamps were on.

Twice in the past two months the vehicle enters a rough low RPM. Will not respond to the accelerator and the engine shuts down. First was in a parking lot the second while driving in school zone traffic. Was able to safely get off the road the second time. The parking lot I waited a few minutes and the engine ran normally. Same for the second time, waited a few minutes and it would not start then a few more minutes it started and ran. Both times all dash warning light lit up but just for a few seconds. If this happens at highway speeds a good outcome seems risky.

Manufacturer Recall Number 209 the federal safety agency Recall Number 21V727000 Incident date: June 15, 2021 While driving on the freeway at approximately 65 MPH, the vehicle stalled with the check engine warning light flashing on the instrument panel, oil could be seen spraying out the back of the car onto traffic which put other drivers/vehicles at risk of an accident. We pulled over into a dirt parking lot, noticed a puddle of oil underneath the car, and then lifted the hood to see oil sprayed all over the engine compartment. I had the vehicle towed to an independent mechanic where the vehicle was diagnosed with engine failure. The vehicle was then towed to a dealer where it remains in their possession as of today which in my opinion is too long to wait without a car, 6 months later from the incident. The manufacturer was notified of the failure June 16th and they informed me that the vehicle did not qualify for any recalls or warranty programs. The vehicle VIN later showed up on the recall campaign in September. Hyundai USA offered to replace the engine at no cost which I am thankful for that so far. However, after the engine replacement, I was told the car would not start, and will require a new battery module and hybrid battery, and that I must pay 40% of the parts and labor at $2776. I believe these parts suddenly failing are directly related to the engine failure incident, and should be part of the recall campaign. My car has yet to be repaired due to backordered parts. I've submitted rental car fee receipts of over $3500 to date without reimbursement because I'm told that it is their policy to only review rental receipts for reimbursement after the repair ticket is closed, with no possibility of interim reimbursement. The Hyundai case manager has told me there is nothing more that they can do, not willing to discuss with another department or Manager, no escalation path forward, and that all I can do is file this complaint with the federal safety agency per the recall campaign notification.

After driving an hour or two, when you stop and fill her up with gas, the car engine will not start after it's full and you're ready to get out on the road again. You have to wait like 20 minutes and maybe more, before the car starts again. Meantime, the gas attendant is already annoyed why you can't move your car?
