| Description of the problem | Vehicle has had a transmission hesitation problem since we purchased it. The delay consists of a 2-3 second delay before the acceleration kicks in. This occurs when merging, turning or attempting to speed up to avoid collisions/objects. We have reported this problem to the dealer every time we bring it in for maintenance, with no improvement in performance. Additionally, under cruise control, the car "skips" gears unexpectedly and revvs randomly. |
