The vehicle shut down while I was driving approximately 40 mph on a major throughway out of town. I was unfamiliar with the area and had to quickly pull over into a resident's driveway. I immediately shut the vehicle down and tried to restart it. It would not turn over, so I waited a few minutes and tried again. The engine then made a noise that almost sounded like "I quit" and would not make any noise when I turned the key after that. I called a local tow company who towed it to Firestone Complete Auto Care which was the nearest open garage. After they ran their diagnostic, they said that the engine had seized and that there was no oil in the reserve. I never had any engine lights light up on the dashboard until the second the car stopped working, when they ALL came on. My mechanic friend says that these engines have computers that time stamp when the warning lights come on, so it will be interesting to know if they use that information. I have contacted Hyundai customer service and because we are not the original owners of the vehicle, they said the powertrain/engine is not covered under the 5 year/60k mile warranty from Hyundai. We do have an extended warranty through a 3rd party company, but they are giving us a difficult time too. We are still waiting to hear if they will cover the replacement of the engine. This is a HUGE safety risk because my vehicle gave no advanced warning that it was needing service/maintenance and just stopped functioning while I was driving. If I had been on a different street or in the middle of a turn, it could have resulted in injury/death of occupants of the vehicle. My oldest son is also just starting to drive. If he were driving this vehicle when this occurred, he may not have known what to do and could have been stranded in the middle of a busy highway, where an accident could have been imminent.

In May 2023 after washing and vacuuming my car, it would not start. The battery appeared dead. I waited and tried periodically, and after about three tries, It started. This happened a couple more times, but always restarted and appeared to recharge. I did not drive the car from June - October, and asked my son to start it periodically while I was away. He tried in Mid June and battery was dead and had to be jumped. The same thing happened in Aug and Sept. Unfortunately, by the time I returned and could get in into Hyundai, it had been 38 months since my purchase. in October the battery seemed to be okay, but the horn did not work. Also, the windshield washer only trickled out and then nothing came out. I made appointment as I had also had a recall on the safety/theft issues. In November, Hyundai of Bradenton, Florida's Serviceman, Mark told me that I needed a new battery which was no longer under warranty and they replaced the horn as it was covered. He said the windshield washer unit was clogged. I chose not to pay $340 for a battery and $80 to unclog windshield washer unit from them. I just feel something is off. On my drive home, the radio came on without prompt. I turned it off, and it came back on seconds later. I turned it off again, and it stayed off. My car is immaculate, and covered when not in use. There is definitely and issue. My Kona only has 21,000 miles on it. Thank you for helping me with this. Please advise.

Came off the frwy and stopped and once I got back and accelerated the car began to make metal grinding sound from the engine drove immediately to the dealership that was less then quarter of a mile away. I left it over night and was told the next day it was not safe to drive at all and there was no loaner cars or rental service. 5 days later a loaner was provided. There was no warning light or alert sound for me to know there was something wrong. The car could had stopped on the frwy and caused a major accident. The dealership determined the short block needed to replaced and took action to have it covered under warranty.

For the last 2 weeks I-??ve been hearing weird engine noises. Like metal pieces being grinded. The car has issues accelerating. Will not change gears properly causing the car to redline on the tachometer. Just today I hear noises a lot more frequently and as I-??m driving and coming to a slow turn the car stalled out on me. I quickly put the car in park and started the car and it started back up. But now I feel a loss in power In the car. The car stalled on me more than six times. Every time I came to a complete stop the car would stall. So every stop sign and red light the car was stalling. The car is still under warranty but I do hope this can be resolved. I know it-??s the engine that-??s definitely having internal mechanical issues and transmission as well. Also the 2 lower headlights are also out as well. This is with the car having 34705 miles only. Wast expecting to have this many issues. I have a video of the car stalling out as well and another showing a rough idle on the car.

My car has been burning oil and knocking and I repeatedly took it back to the dealer with concern that these symptoms are similar to a recent recall on Hyundai Kona engine due to engine failure. Recently I had an inspection (which passed) and as I was driving away from the dealer the engine light came on and I took the car back and the mechanics told me the car is in engine failure! Engine failure can result in dangerous stalling seizing of engine, oil leaks and fires according to the recall information. It is inconceivable to me that my car (2020 Kona) is not included in this recall when I am having the same issues, and this has gone on for three months during which myself and my family (and other drivers on the road) were in danger.

After two years of driving, car seemed to start having engine noises. Felt like loss of acceleration? The vehicle stalled twice after noticing this when in a slower speed. No engine warning light or oil malfunction light ever came on. Our local mechanic said the car was close to being out of oil. Never any evidence of oil on the ground or any type of odor. Dealer was informed of the issue on Nov 9. They said no appointment available until Dec 1, I said the car does not seem safe to drive. Then they changed appointment to Nov 21. No loaner available. Not sure how long this will take to fix if a lot of people are having this type of issue. The car is two years old and with only 12000 miles. We don't go on extensive trips. Mostly drive around town, some highway driving. The servicing was done at dealer at about 6500 miles, they also did something for a "software" recall. And they indicated the next servicing due as 16000 miles. I'm reading some horror stories online, as when there's a problem Hyundai tries to get out of doing the work under their 10 yr warranty. Never, ever had a car that "might need a new engine" (dealer's words) after 12000 miles. Unsafe! Not sure I even trust a "new engine."

My vehicle has a damaged cylinder bore due to the safety recall about the Hyundai 2020 Kona Piston problem. My engine light keeps going on and off-?? My issue is that Hyundai has caused the defect and my vehicle is on verge of breakdown, the problem I have is that they can only fit my car in for service in a months time-??so I have to drive for another month with a possibility of breakdown.

- Montgomery , AL, USA

This vehicle was under recall by Hyundai ( campaign 203 ) For defective piston oil ring. Since day one of owning the vehicle I would notice oil level low by at least a 1/2 quart ( I would top off). After Several trips to the dealer they installed software to detect vibration and it passed. So they said just run it until it dies only then we can replace the engine. Hyundai has since removed car from recall lookup list. Went to 2nd dealer and I'm going through a oil consumption test. They found it uses.4 to.5 quarts ( 2 more tests due). They say this is normal and they probably will not be able to fix the excessive oil consumption. I have a 2020 Kona with 10,000 miles that can't make it through the oil change cycle with out using oil the oil. I don't know what to do at this point Hyundai is not Honoring the recall. They are trying every trick in the book to avoid their obligations.

Leased 5/24/2020. Poor mileage. Told had to break in. On 3/24, 3/29 and 3/30, 2020, car stalled out in traffic. Called for service and given date 3 weeks later. Called Another dealer and got appt. for next day.Spoke to Hyundai Ca. (Sonia) and got case number(1811 5897). On 4/2/2020Blue Link advised to take to dealership, that there was a problem with Engine Control System.The service report was written up that customer states check engine light on.We told them that the car stalled in traffic(very dangerous), but they wouldn-??t write that up. They state that they repaired the car and no code was found. An recall was mailed to house. Made appt for 11/15/2020. Had engine rings recall, they said they did an Atkinson Engine Insp.On 12/6/2020 we received from Blue Link a notice for a possible condition with Engine Control System. At the same time notice appeared car stalled, again in traffic.Called Hyundai Ca. Talked to a Jordan who started another case number, 1905 7159 and he contacted Centereach Hyundai and we had an appt for 12/8/2020. They had to keep the car which meant we were without a car. On 12/16/2020 Centereach gave us a loaner which we were very appreciative of. The car was finally repaired and given back to us on 12/31/2020. Engine was replaced or rebuilt. We had car in for recall on 11/15/2020 and nothing showed up on Engine. Yet on 12/08/2020 they say the engine noise was caused by faulty bearing and piston slap, did a test and found a passing result. They continued to diagnosis and found scoring on all cylinder walls an indication of piston slap to be confirmed, submitted all proper paper work, photos and video evidence to Hyundai for engine approval. After reading in the newspaper about troubles with Hyundai I felt I should write as we could have numerous times accidents with the stalling of car. Hyundai did not acknowledge and repair car right the first time. It was a dangerous situation.
