2015 Hyundai Accent: engine stalls while driving

Filed Jul 31, 2024 · Engine, Transmission · IA

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.

1 year after purchasing car, I had a check engine sensor show up. I took it in and a diagnostic test showed an o2 sensor needed to be replaced. I replaced it and the part was defective, so I took it back and they replaced it again, after which it appeared to be fine. Then less than 6 months later, it began to run poorly and would not accelerate properly and seemed to not be getting fuel or oxygen or something. I took it in again and ended up having a catalytic converter put it for over $500. It ran fine for maybe a month after and the check engine light comes on again, it was running poorly again, losing power almost stalling out when pushing accelerator, it smelled like burnt oil. I had oil checked and changed 3 times during the time this all was happening too because of the smell of burning oil. Each time the oil change was done the service technician said it appeared not o have been changed because it was black and burnt and low, which is not possible, due to how frequently I was having it checked and changed not knowing what else to do!!! Ultimately, on my way to my parents house the engine blew and smoke poured out from under it and it would not run again and it appeared to be burning. Upon inspection there was a hole melted into the engine block!!!! I am so disappointed in this vehicles performance. I had the vehicle from 2017 to march of 2020, still owe money on it and cannot drive it or afford to get it fixed. This engine failure was not my fault or due to my failure to properly car for the car. This is a hyundai issue and it is time someone be made aware that this happened to what could have been a life long consumer, but never again!!!!

1) 6/8/15: when I stopped at a traffic light, the battery light came on and the car stalled. After I turned it off and turned it on again, the problem disappeared. 2) 7/27/15: a similar situation recurred, again after stopping at a traffic light. This time multiple warning lights came on, including engine oil pressure, parking brake/brake fluid and something else. The car stalled again. And again after turning it off and on the problem disappeared and then I could drive. 3) 9/24/15: I was driving at the speed of 60 MPH. Suddenly multiple warning lights came on and I was afraid that the car can stall. Fortunately, it didn't happen. The lights stayed there for a few seconds and then disappeared. But another weird effect occurred: trip a miles, which was about 50, reset and started from 0. Most likely it is a computer malfunction. With this issue the car is unpredictable, unreliable and dangerous.

On january 30 2015. I was driving at about 65 MPH .upon entering the tappen zee bridge all dash lights came on and I encountered a substantial loss. Of speed/power. Top speed was around 5-10 MPH. After getting to safe place , I contacted hyundai roadside assistance ,they told me it wasn't their problem. After a 3 hour "cooldown" I was able to transport the car to rockland hyundai. After several more hours the service tech told me " the dealer prep button " wasn't pushed. This sounded suspicious , so I contacted several dealers. I was told by all of them there isn't a dealer prep button. However there is a switch. Was also told if this switch wasn't activated the car would not do what it did( go into safe mode) . The switch controls accessories ( power windows, radio, lights...) to this day I have been told what really happened. I also filed a complaint with hyundai, but all I get is them stalling.
