The car would not accelerate, nor switch gear while I'm driving middle of the highway. The car engine started to shake after my car wouldn't switch gear. The car engine would not start after turning the car off and caused a engine misfire. The transmission gear has a hard time switching gear from 0-40mph. This same incident occurred twice since purchasing the car in late November 2022.

The car did not shift from Drive to Park after coming to a stop and pressing the Park button. This caused the car to roll forward slowly and run into our garage door. This is not the first time the car hasn't shifted.

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.

I was driving on the freeway, at the speed limit, cruising along. Then all of a sudden, my vehicle starts to decelerate from 65 MPH and I push the gas, thinking I must have let up too much on the pedal. However, that only causes the RPM to drastically rise with NO change in my speed. I thankfully managed to maneuver from the far left lane to the freeway shoulder on the far right. The whole time, my speed was around 40 MPH and dropping drastically. Trying to safely navigate a slowing vehicle on a 65+ Texas freeway is an adrenaline-rush that I wouldn-??t wish on anybody. I was severely panicking. I was almost hit by several vehicles in my maneuvering. I could have died last night. Once on the shoulder, I tried to start my car. I thought it may be a battery issue, but it turned on. It didn't start, though. The lights came on, as did all of the typical system/dash lights that usually indicate when a car-??s engine hasn-??t -??turned over.-?? I used Bluelink to call for roadside assistance (since I-??m only a little over 2 months into ownership) and waited. I was escorted off of the freeway to safety -?" thanks to a 3-car police escort AND free city tow trucks -?" and eventually picked up by Hyundai-serviced AAA. The latter then towed my vehicle to the dealership where I bought my Sonata. My car is currently being checked/inspected by my dealer (North Freeway Hyundai) and I only have gotten the following notice from Bluelink: "A possible condition with your Engine Control System has been detected with your 2023 SONATA on 02/22/2023 at 07:23 am CST. A full system check is recommended to be done soon." I checked and there are no open recalls (currently). Even more concerning, my car recently underwent complimentary maintenance, including an oil change, through my dealer (on February 13, 2023 - I have the receipt), was good on gas, and had no warning lights displaying. Until it stopped running -?" the time I tried to start it on the side of the road, the dash showed an -??engine-?? light.
