2023 Hyundai Sonata Power Train

At least 8 times when driving the car the transmission switches from the drive “d” position to the park “p” position and I have to cut off the car and then restart. It is very dangerous as I can be rear ended which can result in personal injury as well as an insurance claim. I’ll put the last date it occurred but started experiencing soon after I bought car.

On January 6, 2026, during my morning commute in heavy traffic, my 2023 Hyundai Sonata engine unexpectedly turned off, causing a sudden loss of power. This created an extremely dangerous situation, and I came very close to being involved in a major collision. While I was fortunate to avoid a crash, the incident posed a direct threat to my safety and life because of the dense surrounding traffic.

I have been having transmission issues the whole time I've had the car. There is a delay upon take off, and it bogs down instead of downshifting. I was driving my son to school and made a left turn. It started to go but then delayed for 10 seconds before suddenly taking off. If the on coming traffic had been closer, they would've hit us. The dealer has reproduced the problem but can't get enough information for the tech line to approve a new transmission even though the dealership has repeatedly said that is what it needs. I've never had a warning light on it. it's been in the shop for it this time since 7/26/24.

Transmission goes into limp mode Please note this is an N line and shift points are low taking off from a light vehicle goes into limp mode in first 150' cars to the rear almost ran into the back of the vehicle. Car is 2 days old and I have an appointment tomorrow to have it looked at. This sounds like similar problem that caused a recall last year on the 2022. This is a dual clutch auto.
