“For the Engine problem While driving the car there was a warning about the battery and asked to check the manual, immediately after that another warning was coolant too hot and the car shut down in the middle of the road For the transmission problem While driving the gear went to Neutral by itself. I put it back in drive about 4 minutes later it went back to neutral by itself and I had to put it back in drive No dashboard warning”
NHTSA complaint #11511088, filed 2023-03“Engine does while driving; when accelerator pressed there is often a delay of several seconds before the car speed will increase as the engine will rev but the transmission will not engage for several seconds. This is occurring sporadically but with increasing regularity. Dealer cannot find any error codes. Seems like it’s a fuel pump and/or computer chip issue.”
NHTSA complaint #11541807, filed 2023-08“After driving the car about 5 miles at about 10 miles per hour while decelerating the transmission shifted into neutral requiring me to need to pull over to the side of the road, put the car in park, turn it off and back on again, this has now happened 3 times in the span of about 1 week.”
