1 Engine And Engine Cooling problem

Failure Date: 08/06/2025

My 2015 Hyundai Accent started having problems with oil consumption around 65000 miles. I got it checked regularly and the mechanic noticed it after it was having issues accelerating and losing power then cutting off completely. I had to constantly check oil each week or sooner. A couple months later it started losing power on high way and there was a clicking/ticking coming from engine. I pulled over and cut it off. Then drove it slowly (under 30 mph) to car store down the road to add oil but it was fine. Was able to get back home on back roads going slowly. Mechanic told me there oil consumption was a problem with these types of cars and likely causing engine problems. The whole time I had problems the check engine, battery, and oil light would constantly come on and go off. When they hooked it up to see why check engine light was on there were about 15 different codes. One of them being the variable valve solenoid which I ended up replacing both first but still had problems. It would accelerate but there was still a ticking noise upon accelerating. I didn’t drive it for a few weeks then the day I was going to take it back to shop, my husband, his friend, and I were on highway a couple minutes from home and hit a bump and heard a loud thud when the ticking stopped but the car beside us was waving to get our attention that the car was on fire. There was smoke coming through a. C. And you could see it in the rear. My husband quickly pulled over and when I went to get out of passengers side, flames shot up my side of the door so I quickly jumped across out his side. We were able to all get out ok. Luckily there was a firetruck coming down the highway before I could even get ahold of dispatch on 911. The cars front end was engulfed in flames which they were able to put out quickly. The hood was roasted. I’m not sure if they determined the cause and my car is still sitting in the lot where they towed it. Unfortunately I had a lapse in insurance because I was out of work.

2 Engine And Engine Cooling problem

Failure Date: 07/29/2024

My 2015 Hyundai Accent started having issues with oil consumption at about 80,000 miles or so. I was having to check and add oil to the vehicle regularly in addition to oil changes. The oil consumption issue got worse as the vehicle got higher in miles, having to check and add oil every 600-1000 miles approximately. I was not aware of the known issue with Hyundai motors and the oil consumption so I was not tracking milage or dates of adding oil unfortunately. At about 100,135 miles, the vehicle suddenly broke down on my way to work. There was no warning other than the oil consumption problem. The car rpms got very high and the car started decelerating until it wouldn't go forward anymore and was stalled on the side of the road. I had the vehicle towed to a Hyundai dealership and at this time it waiting for the diagnosis, however, they are sure that the head gasket has to be removed (for $500) to get that diagnosis. When the car died, there were no warning lights on at all, however, previously, there had been lights for low oil occasionally, but not always, when the oil was low. Many times when I checked and the oil was low, there was no light that indicated that it was low.

3 Engine And Engine Cooling problem

Failure Date: 03/15/2024

On 15 Mar 2024 the engine in my 2015 Hyundai Accent suddenly failed while traveling on I-80 w near milesburg, PA. While attempting to accelerate, the vehicle completely stopped. It was able to be coasted to the side of the roadway, but was unable to be driven after that. It was towed back to south williamsport to steve shannon's garage (where it still sits). After inspection by the mechanics it was noted that there was a hole through the engine (not from puncture) to where they were able to watch the pistons moving from underneath. There were no warnings or issues prior to this event. This event put my brother, sister in law and two toddler nephews in danger as they sat on the side of I-80 waiting an hour for me to get there to pick them up, as they were borrowing my vehicle to take a family trip to the pittsburgh zoo. I believe the speed limit in that area is 65mph. Therefore, traffic (to include semi-trucks) were traveling at least 65mph passing the vehicle and my family on the side of the road. Psp was able to come out and stage with their lights activated until my arrival.

8 Engine And Engine Cooling problem

Failure Date: 06/11/2021

My check engine light came on and stayed on, while the oil light appeared when my car was in idle and the engine began to knock. My aaa approved mechanic determined that the engine had a rod knock and the oil pressure at idle was only 3 psi. In other words, the the engine had completely failed and would have to be replaced. At 36,000 miles !I had the car towed to the local dealership where they confirmed this diagnosis and noted excessive metal debris in the oil and oil pan. My research revealed that an identical engine manufacturing defect had resulted in a class action suit against Hyundai which was settled in 2018. Hyundai was forced to replace the engines with new ones and cover all the owners costs for 3. 9 million complainants. They also suffered a huge fine by the NHTSA. Because of covid lockdowns, I had driven my car very little in 2020, otherwise this catastrophic failure would have occurred well within the the 5 year warranty period. As it was, the warranty had expired approximately 4 months earlier. The dealership contacted Hyundai n. A. And I was offered a "goodwill offer" which allowed me to pay over $3200 for a reconditioned engine with a warranty of only 1 year or 12,000 miles. It is my contention that no reputable car manufacturer would consider an engine life of only 36,000 miles to be acceptable. There is no question that the engine failure was, in any way, my fault and I have the maintenance records to prove it. My "goodwill offer" expired and I towed my car home. Of course, I was fortunate that my engine did not fail on the freeway, at high speed, or burst into flames as some Hyundai engines have been known to do.
