2022 Hyundai Sonata

Shifter system malfunction service immediately was displayed on my dash 10+ times which caused me to not be able to shift my car out of drive or whatever gear I was in when this occurred. I was at an intersection and when I was coming to a stop the car displayed this error code and wouldn’t allow me to go until I turned the car off and on twice till it was able to reset back to park then allowing me to start and shift to drive to actually go. This jeopardizes my safety and the safety of others considering my car could give out or not change gears at any given point. This is extremely concerning. The problem has not been reproduced by the dealership but has been in 2 times for this issue within a month. I took pictures and showed it to the dealership and they said Hyundai won’t cover it. They felt bad and believed me so much to the point their service department is covering the cost of the Transmission shifter module (TCM) in hopes this will resolve the issue. Only a Hyundai dealership has worked on my vehicle.

When driving down a hill, I downshifted to slow my descent and to not have to use the brakes as much. I downshifted once or twice making sure the engine didn't go far above 3000 RPM. The gear indicator showed 2nd gear but I knew that wasn't accurate because the car had yet to change gear and the RPM was too low for 2nd gear, I was still in 3rd or 4th gear. About a second or two goes by until the car slams into gear incredibly hard, physically jolting me and the car. The engine revved up loudly to about 4-5K RPM. Had a car been closer behind me, they could have run into me. There were absolutely no warning lights or indicators before or after the incident. The transmission had been shifting noticeably more rough for a few weeks after and perhaps a bit before the incident. The transmission always felt rough up until 4th gear when travelling at slow speeds. but this was something else. It hasn't happened again to the same degree but there have been automatic shifts on its own that are uncomfortable feeling. I have not had the car inspected yet because it is difficult to find a dealership appointment that isn't 2+ months in the future. I had scheduled a full thorough inspection with all of my complaints but had to cancel to due personal reasons.

On multiple occasions, the car has intermittent acceleration issues and hesitates when the automatic transmission is shifting to the next gear. Without warning, the car completely turned off - engine failed - while driving and in the middle of making a turn, and luckily oncoming traffic stopped in time before we were in an accident. The local dealer has been unable to replicate the problem; however, there is an open recall on the same make and model but my VIN is not currently included in this recall. This is not a coincidence and this vehicle is not safe to drive. I also already contacted Hyundai directly but the case manager has yet to resolve the issue, just says the VIN is not part of the recall.
