I bought this car March 2022 with 56.000 miles on it. I have had the car for 1 1/2 years, car gave no warning, motor seized at night on the highway, it had a loud noise and did not even have enough time to get to the shoulder. Hyundai Motors is saying it is not their issue, considering I have found tons of documentation there are many engine issues with these cars. This is dangerous and could have been a fire. My son was driving the vehicle could have been hurt very badly. He was driving 65 MPH and when the engine seized it stop abruptly stalling on the hwy. I have read hundreds of claims of engine fires. Hyundai is not taking responsibility.

After all work performed vehicle engine light was still on and was driving rough at times still stalling on the road. The car would stall constantly with out warning. Sometimes will start up again and sometimes it wont. Then increased oil consumption, progressing to a knocking sound, and the engine seizing and stalling.

I was driving on the interstate and suffered a sudden loss of power with a check engine light. I stalled on the interstate which is dangerous. Waited 2 minutes and started the car again, check engine came on almost immediately. Drove off the interstate and had car towed to dealer. Dealer Tony Hyundai found no oil in the car and the engine failed a bearing clearance test. The dealer serviced the engine under Hyundai CPO warranty but I am concerned that there is no root cause of the engine failure. I am reporting to NHTSA in the hopes that other owners who experience this will also report it and if there is a common problem it will be discovered. Additional documentation is available by request.

What component or system failed or malfunctioned, and is it available for inspection upon request": Faulty piston oil rings resulting in scoring on cylinder walls How was your safety or the safety of others put at risk? Continual operation of the vehicle in this condition could result in a seized connecting rod bearing, which could cause damage to the engine block and eventually stall the vehicle. In limited instances, a connecting rod could puncture the engine block and cause engine oil to leak, which, in the presence of hot surfaces, could increase the risk of a fire. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes it has been diagnosed by an official Hyundai dealership Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not to my knowledge Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" I've had this vehicle taken in for repairs 3 different times all associated with engine issues or oil leakage despite keeping up with routine maintenance on the car The contact stated that their vehicle may be associated with an existing recall, but the VIN does not come up when searched. That might be because the recall investigation only looks at one manufacturing plant.

I was driving on the freeway & the engine just cut off. I lost complete power but luckily, I was able to get to the side of the road without any incident. About a month ago, the same thing happened but I was down the street from my house so it wasn't a big deal. The day after, the front collision light went off twice while I was driving. My particular car VIN number is not on the recall list.

My 2019 Elantra has stalled while in motion 5 separate times since 15 November 2022. My warranty claims are based on a defect in the vehicle-??s material or workmanship that is covered by the Hyundai New Vehicle Limited Warranty period of 5 years from date of original retail delivery and 60,000 miles. Why I believe the problems are the responsibility of the manufacturer: This began 15 November 2022 when the Malfunction Indicator Lamp came on; I brought the car immediately to Bay Hyundai. They replaced the camshaft assembly. Since then, the engine has stalled while in motion 5 separate times. Why I believe I have not contributed to the cause of the problems: I have properly maintained the vehicle as proven by all of the service receipts from Allen Turner Hyundai, Bay Hyundai, Pep Boys, Tuffy, AutoZone and CARFAX. My 2019 Elantra has low mileage: 45,000 miles over 4 years. The motor vehicle defect is not a result from an accident, abuse, neglect, modification or alteration by me. Why the problems represent a substantial impairment to the use, value, or safety of my vehicle: I can-??t even drive it 1 day without the engine stalling without warning while in motion! This jeopardizes my safety and has caused severe anxiety from breaking down in traffic multiple times.

- Panama City, FL, USA

The engine is burning a lot of oil. It only has 125000 miles on it and no leaks. I am worried engine will stall while driving due to low oil.

I was driving home from work at night when my 2019 Hyundai Elantra Sport (just found out has the wrong VIN) lost all power and felt like it wasn-??t running on all cylinders. I switched it to sport mode had a little more power for about 2 mins then my car died completely. I had to pull over thankfully I made it to the bottom of the pass and coasted into a gas station while I waited for a tow truck to have it towed to the dealership. The dealership had my car for almost a week. They ran all kinds of diagnostic testing, one of which came back showing my engine lost almost all compression. Secondly they ran more tests and more tests and just to tell me it was a bad battery. The battery has been replaced. My car is still having idling issues, it-??s shifting hard and the lane Assist which I kept on just the warning turns itself on randomly, same with the front assist. This vehicle has 37,000 miles on it. Maintenance has been done regularly along with the highest quality oil changes, premium gas and air filters. I AM PISSED THAT I AM PAYING SO MUCH MONEY A MONTH AND AM HAVING NOTHING BUT ISSUES.
