| Description of the problem | Hesitation and delays in acceleration when driving from 0 - 30 mph. Originally it started with the rpms dropping way down before catching. Brought the car in for service and they replaced a brake sensor. The problem became much worse. When reaching 30 mph the transmission felt like it went into neutral and had a problem catching. Rpms jumped way up to 4 and revved 3 times before catching. Leaving me unable to have control over the car. Very scary. The car has been at the dealership for a week and will not duplicate the problem when driven by the mechanics and is not throwing any codes. According to the dealership they are unable to fix this because they do not know what the problem is. I am being told to bring it back if it happens again. The majority of my driving is city driving. My commute to work is approximately 30 miles round trip, 5 days a week and seemed to get worse in the rain. |
