| Description of the problem | I have taken my car in to the hyundai dealer three times for service to and they have been unable to recreate the problem or diagnose the problem via a code. I had the transmission fluid replaced thinking that might originally be the problem. The car hesitates in lower gears when it is in ev mode and will rev at higher rpm before slamming into gear when it goes into gas engine mode. When coming off the highway and decelerating it will slam hard into gear as the car brakes and goes into ev mode. It is not consistent and every time the car is brought into the dealer they claim there is nothing worn with the car and they cannot duplicate the issue. When pulling out from a stop sign in ev mode there is absolutely no power some times and all of sudden the gas engine will kick in and accelerate. I have had other issues with the hybrid battery just shutting down on the highway so it concerns me that there is more of an issue that needs to be addressed. |
