I have had a few problems all seem to be related to electronic throttle or throttle position sensor
1. Car completely lost power wouldn't respond to accelerator, in a busy intersection....luckily I was able to turn it off, restart it, then limp across to a parking lot. Had to tow car to the dealer. Error light showed it was the TPS. It was adjusted.
2. Happened again in about a week.
3. Recently problems with excessive revving at startup, at first it would just "vroom" and go back and forth between 750-1000 rpm, no big deal but kind of weird. A couple weeks later it revved to 2500 rpm before I had even put it in reverse to leave my garage, kind of scary as it felt it was going to take off at high speed. No error or warning lights with either of these events, dealer unable to reproduce the events.
4. I saw a post from another member (mcginnpm)about another thing my car does, I call it chugging or shuddering. When driving at highway speeds, with or without cruise control, it will occasionally give a shudder or chug-chug hesitation, then go back to driving smoothly. When this happens there is no change in the rpm and no warning lights.
5. I saw a post from another member (ehayden1) describing the final problem I am having, with trying to accelerate smoothly from a stop. As he describes, the car hesitates, leading me to apply a little more gas, then it kicks in a little abruptly. I's like a bad shift sequence or like my bad driving with my one manual transmission car in the past. It has not always done this and I feel bad for my passengers!
I still like my Genesis and I drive it A LOT (60 to 90 miles a day).
Any advice for any of these problems is welcome
