“Car shut off while on the highway randomly started shaking. All lights turned on check engine,motor oil light battery light. Car shut off to the point where I couldn't accelerate. So imagine being on the highway and your car shuts off randomly while your in motion and cant accelerate to merge to the emergency lane. This happened 4 more times on my way to the dealership less then 800 miles!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!”
NHTSA complaint #11130331, filed 2018-09, 800 miles“I bought a 2018 Hyundai gt sport 3 months ago. Since day one car has been stalling and having a hard time starting. I was on the highway doing 75mph and the car just turned off no warning. I called the dealer in my area let them know about the starting issues and the stalling issues with the car I took it in to them few days later. They kept it for 3 days and told me sorry we do not know what to tell you. Took it home and that day the car stalled on my way home. …”
NHTSA complaint #11185997, filed 2019-03, 87 miles“I was driving on a the interstate going 75 MPH when I heard a loud thumping noise from the front right side, I lost power steering, power brakes and the car shut off. I had to struggle to maneuver and stop the car to the emergency lane. It was then towed to the dealer that discovered the timing chain failed. The timing chain also damaged other internal parts throwing fluid throughout the engine and causing metal shards from other internal components. The car has 32k miles and less than 3 years old.”
NHTSA complaint #11399096, filed 2021-03, 32,000 miles“It uses a lot of oil with no visible leak or reason. I put new oil in all the time. All the time! For two years since buying it used. Warning light does not come on till it's out. Car is hot, of course, and stops running in the middle of the road. I see there is a recall on some elantras for oil piston seals but not this car. Seems it should be.”
NHTSA complaint #11670888, filed 2025-07“I have noticed over the last year or so that the engine was burning oil. This was indicated by Express Oil Change multiple times during oil changes, including today. The oil level today didn't even register on the dipstick, so it seems this is getting worse. I can get oil change records on request from the above company.”
