1. The engine failed due to rod knock - rod bearing wear/damage. This vehicle is in the possession of Killeen Hyundai. 2.

On January 29th I was driving my 2012 Hyundai Sonata to my dads and the check engine light was on. We used a scanner to see what codes were present and there were none so we cleared the light. On February 1st we were driving back from getting tires put on the car and getting the inspection done and the engine seized up with no warning while driving. We got the car towed to freysinger Hyundai in mechanicsburg pa and when they looked over the car they stated that it failed the bearing test and due to the engine failure recall on my car Hyundai should replace it. Hyundai is denying the engine replacement because of the previous owner didn’t do the ecm update when that has nothing to do with the bearings and oil in the car.

Original Report: 1/28/22 to HyundaiUSA Problem with car started day after alignment. First noticed (while going up driveway) pressing accelerator did nothing - press again then OK. Got out to open gate, noticed brake lights on. Later (after dark), came out and brake lights on. Driving home noticed ESC light on - ESC off button had no effect. I found this exact description on "CarComplaints.com" from 2019 and it references recall #136. Next day I cranked the car, and the "ESC off" indicator came on. I was then able to turn off with the ESC off button. Update: 1/29/22 Next day same issue with brake light. Able to reset ESC light but it came back on after driving about 15 miles. I noticed that the issue with the sudden deceleration occurred while going 55 mph. It happened about 3 times in the 5 mile return trip. Releasing the accelerator pedal then pressing again provided acceleration. When I got out of the car, the brake light remained on. Update 1/30/22 The ESC light reset itself automatically when I cranked the car. While warming up the car in the garage, the brake light came on and I tapped the brake to turn off. This happened 4 times. I was pulling out of a side road onto a busy road with limited sight of oncoming traffic. As I started out, the acceleration died, and a car came around the curve/hill. I managed to release the accelerator and re-apply and got out of the driver’s way – he was able to slow down enough to avoid an accident. Issue happened several times while driving to my destination. A few minutes after going inside, the car security horn started sounding. I used the remote to turn off. I went back in, and it started blowing again. I pulled the fuse for the horn from under the hood. The ESC light did not come back on during this trip but the brake light did numerous times. My research found that the brake light switch has been blamed for some of these issues. But a faulty brake light switch would prevent engaging gear shift.

About a year ago, my 2012 Hyundai Sonata Hybrid had an error with an alarm that would pop up on the screen but was too fast to catch what it said. It would happen a couple of times a month. One day, I was driving about 60 mph and the alarm came on, the car stalled and it said to not drive the car. I was able to roll to a stop on the side of the road. I turned off the car and had it towed to my house. In looking at it, I turned it on and everything seemed fine. This happened another time about a month later. The second time, I just turned off the car, let it sit for a minute and turned it back on. I took it into a dealer and they said they couldn't figure it out and to bring it back if it kept happening. It hasn't had a problem since then until this morning. Here, nearly a year later, I was in the middle of a busy intersection and it gave the error and alarm and the car stalled. I turned it off, let it sit for a few seconds and then turned it back on and backed up. Fortunately, the cars coming at me noticed I couldn't move and stopped! I would pay to have this fixed if they knew what was going on! Everything I see online about this issue, no one knows what is causing it. I wouldn't feel comfortable selling it to someone else knowing this is such a safety issue. It's just a pile of metal at this point.

While driving the car started smoking white smoke and locked up. I was unable to get off roadway and almosred caused wreck. Had vehicle towed to dealership they said ut had a recall on it for engine failure. Checked the engine and it was locked up. They submitted the engine replace to hyundai and they denied because I didn't have a software update done prior to engine failure. Had no warning at all.
