While driving my car with no warning light or any type of sound just cut off engine while driving. I was on busy highway going slightly uphill and was almost rear ended causing car behind me to swerve to avoid hitting me swerving to other lane and almost colliding into another car. I was able to get to middle divider almost but back end of my car sticking out in #2 lane. I was stuck in car for about 10 minutes then got across Street to sidewalk. There was no warning, no smoke etc prior to engine cutting off. Everything still works lights, a/c, radio etc . Engine tries to turn over but then slowly dies out like a battery issue however I have a 2 year old battery and when I charge it or try to jump start it it doesn't start also everything else powers on. I have had it stall 2 times before on L.A. freeway in which I somehow was able to cross over 4 lanes coasting to side of freeway. And at that time was sideswipped by another vehicle to front of car and car kept going and I really didn't have time to think about that while just trying to maneuver safely to side of freeway. The 1 and 2nd time it stalled it did restart after about 10 min. But this 3rd time it hasn't started again. The most recent incident was4/15/26. Another issue is the massive amounts of oil it consumes. I put in 2 quarts a week . But there is never oil leaking on driveway or anywhere its parked so where is oil going. I've had it checked several times and they said that these cars burn through oil and I also told Hyundai dealer about both issue and nothing was ever done. My s Check engine came on and I took in to shop and picked it up after paying alot of money and light was off but about a week later on. Took it back and pick up and lights off running good another couple thousand again. And on and off just randomly and auto mechanic shop said I would need to take to hyundai dealer to see whats happening. Called and told them never heard back. I have more pic of repairs but couldn't load more

On April 12, 2022. I was driving with my grandson. I heard some loud engine noise in which I thought was coming from an old red truck next to me. I continued driving and continued to hear the noise after I was away from the truck. I realized the noise was coming from my vehicle (2016 Hyundai Sonata). The interior lights started flashing ( oil light, engine and battery lights) and the car started losing power. I was able to pull over to the right lane by the curb. The engine shutdown and wouldn't start back up. The car was towed to Jeff Wyler Superior Hyundai, 238 W. Mitchell Ave., Cincinnati, Ohio 45232. My vehicle is still there. In January of 2022 I had my car at the dealership for losing power. They repaired it, saying it was the cylinders and then in April 2022 the whole engine shuts completely down.

Yesterday, my car’s engine/battery/oil lights came on. I pulled over, checked the oil and it was almost completely dry. I went to start the car again and it would not start. After my mechanic checked the starter and battery, they determined that the engine was locked up. My engine could have caught on fire as there was no warning prior.

The car when driven highway miles will not crank when you stop the engine. The check hybrid system light message comes up. The car will not start for 15 to 45 minutes. The engine light is on once the car starts but the next day there are no lights or diagnostic codes. Stopped in a drive way and had to push it. This is not the first time. Happened 3 other times.

On september 1,2019 my car wouldnt start. I purchased a battery and a it turned over. On september 8th I drove to get a oil change and tune up which seemed abnormal when I got home. There was a ticking noise. I wasnt sure what was causing the ticking noise so I didnt drive the car. On september 9th I got into car and started it when I noticed a knocking noise, the noise accelerated once I pressed on gas pedal so I didnt want to drive it. My check engine light is rapidly blinking.
