| Description of the problem | There is an intermittent lag in throttle response after pressing on the acceleration pedal for approximately 2 seconds. During the lag period, the vehicle does not accelerate. This is a problem that is then followed by a lunge in the vehicle, almost as if the vehicle? S electronic acceleration system, ? Drive by wire,? Is trying to catch up with the depressed acceleration pedal. This has occurred at very inappropriate times, where we would have to suddenly apply the brakes abruptly. The nature of the defect is unusual and not only poses a safety problem while the vehicle is lunging, but also poses a serious safety issue, if we were trying to merge on a limited access highway. Being that a vehicle traveling on a limited access highway may be traveling at 60 mph. That vehicle will travel approximately 176 feet in that two second lag time of our vehicle? S acceleration system. |
