The engine seized up completely and the car would not start. The car ran fine prior to this on the same day and there were no warning lights or warnings when a portable code reader was plugged in to assess the problem. It was towed to a mechanic who said it looked like excessive oil consumption as the oil was changed only 6 weeks prior and the level was assessed to be perfect then. This is a safety risk due to the engine seizing without warning. If this were to happen while driving, it could cause a fire or cause the driver to be stranded on a busy road, causing accidents. The car is being looked at by a hyundai dealer currently.

For the now 2nd time for the SAME problem as before, I was on the highway and the car just cut off mid drive on 8/17/2024 @70mph!! Engine light came on. Later that day while on the street, 35-40 mph, ALL OF A SUDDEN NO ENGINE LIGHT ON... the car cuts off again mid drive!! I purchased the car with roughly 15k miles on it and it's been absolutely nothing but issues back to back. The daytime running lights constantly blow out also. The shop supposedly repaired this issue when I put it in the shop the first time, but it's doing the exact same thing again.

Vehicle started making strange noises and not accelerating properly. On April 1, 2024 Took to dealership where purchase was made and it died upon arrival. Dealership couldn't identify issue but believed oil consumption was excessive and said to take it to a Hyundai dealer. On April 30, Hyundai tech said issue was a valve and would be fixed by May 3. It is now May 15 and my vehicle remains in the shop with no resolve. When I dropped my vehicle to the Hyundai dealership I informed them about the possible oil consumption issue and they have yet to examine that.

My vehicle will randomly stop driving and then might be fine. The check engine light has been in for over a year and the dealership says it leaks oil and builds up sludge when we were only taking it to them. When checking the code for the check engine light it says it-??s the cam shaft sensors. The dealership said it was fine and cannot figure out why there is a light or why it stops driving. Last night it was sputtering when breaking and then when turning.

The piston oil rings may not have been properly heat treated, which resulted in engine damage.

I am experiencing an issue where the O-rings in the engine are not preventing oil from entering the engine stated by a repair shop that took a look into issues where my engine would cut out while driving, lurching when downshifting. I believe this to be related to a current recall that is happening with 2019-22 model elantras. This poses a significant safety hazard to me and other drivers due to the engine cutting out while driving and prevents oil from being distributed in the engine without a warning light telling me that my oil pressure and oil level were low potentially causing a vehicle fire. I received a check engine light and not long after started to see my engine cut out, lurch and have a significant lack of power about 20 miles after the check engine light came on. My car currently is at 67k miles and mostly use it on the highway.

Vehicle stalls when coming to a stop or light. Very reminiscent of recall [XXX], but when I called local dealership and Natl Hyundai Customer Service, I was told that the recall was not specific to my Vin Nbr. The vehicle stalls in traffic which is extremely dangerous and gives no engine light or OBD code. I have taken it to a few local mechanics and they cannot resolve the issue. They have changed parts that could possibly be the issue, but it solves nothing. The vehicle has 109,471 miles 2019 Elantra which is practically new still. I would like my Vin added to that recall so it can get fully checked out by Hyundai. Ive spent a few hundred dollars already and am tapped out, plus the stress of getting into an accident crosses my mind every day and worries me. Thank you.

bought this car for my son's graduation the car had 59000 miles as a used car. The engine seized after one year and 18000 miles. No one is taking responsibility and I still owe 15000 on this car. Many articles have been written about the engines being defective. Hyundai will not help me because they say there is a Korean engine in this car. What the heck does this have to do with it I bought a Hyundai. I have been to the dealership, the car company, the car salesman at the car lot I bought it at. No one will help me. I sit with a dead car and in dept 15000. Where do I go from here.

While driving on the highway, engine light comes on and THEN CAR SHUTS OFF MID DRIVE. Days later, tire pressure light comes on and stays on showing GOOD pressure. The car doesn't properly shift gears. Luckily I didn't have an accident. I have a case opened with Hyundai, but unable to get diagnosis until March. Car hasn't been consistently operable since purchase 3 years ago, as you can tell by my mileage

Car kept stalling. Then wouldn-??t start. Mechanic found a ton of sludge in the engine. Engine is bad now. I kept up on routine maintenance. Lots of engines are being recalled except for my specific one with the same engine problems.

- Pensacola, FL, USA

The vehicle has demonstrated a recurring and dangerous problem of stalling while in operation, without any warning indicators or lights. This fault has not only persisted but has also led to a near-collision incident, underlining its severity. The first occurrence of this issue was when my car stalled unexpectedly during regular driving, with no dashboard warning lights or indicators of a malfunction. After taking the vehicle to an authorized Hyundai dealership, I was informed that the car was burning oil, which had spread throughout the engine. This diagnosis led to costly repairs amounting to $2,500. However, merely two months post-repair, the same problem reoccurred. The car stalled abruptly as I was merging onto a highway, nearly causing a severe accident. This incident was particularly alarming as it happened without any prior warning or indication of engine trouble. I emphasize that I have diligently maintained the vehicle, adhering to the recommended 3,000-mile oil change intervals and ensuring all fluids are regularly checked and replaced as necessary. The recurrence of this issue despite proper maintenance raises significant concerns about the reliability and safety of the 2019 Hyundai Elantra model.

I was going 40MPH when my car started to produce loud noises and stalled. It immediately lost power and I had to pull over on the side of the road. It started back up after 30 minutes and I was able to drive it home, but it continued to make loud noises and I had to drive very slow. Battery is good with 70% charge and the alternator is good.
