When accelerating from a stopped position, the vehicle would go into first gear and accelerate for a few seconds, then would try to move up to a higher gear and get suspended for about 5-7 seconds as if it could not find the next gear. This has happened 2-3 times so far. Also, when I have tested the response of accelerating by pressing the gas while traveling at a low speed, the vehicle would not respond as expected. On several occasions, I pushed the pedal to the floor and the engine only responded as if I was slightly accelerating. I have a 1. 6 turbo. Additionally, I have had the lights on my dashboard go out - except for my radio/navigation system. I suspect this had to do with a sensor as it was dusk and my lights tripped some electrical or software defect. I was going down a major highway around washington d. C. At the time and could not see any of the driving controls for approx 20 seconds. I am not sure if my headlights went out at that time but eventually, after flipping my lights off and on and pressing the dash light to maximum, the lights on the dashboard returned. Last week, the audio of my radio/navigation system would not work. After leaving my car and locking it for about 20 minutes and returning, the sound was working again. I took a video of this. The temperature in my vehicle was not regulating properly while stationary. The dealership said there was a bad sensor and replaced it. It has worked great since then. However, I am still having major problems accelerating from a stopped position from a red light or turning into a road, or accelerating from a very slow speed. My vehicle is now in a second dealership trying to resolve this issue that still lingers. This is causing me to feel very insecure about driving my vehicle. I am second owner. First owner had only put 2500 miles on it and traded it in. Probably a bad sign.
Transmission fails to engage on some occasions when attempting to accelerate from a stop or accelerating into a turn at an intersection. Acts as if the transmission does not know what gear to engage. Dangerous when attempting a left turn as you stall part way thru the turn. Have had car back to dealer twice and they claim no problem. I feel that this is a legitimate safety issue that needs investigating as I see multiple similar complaints on your website and other internet sites.
