“I am unsure of the first date of occurrence, but the following have been happening since I purchased this vehicle new with 12 miles on it. And the dealer can't find anything wrong with it. 1. The AC always comes on. Even when it's below zero outside. 2. It fails to go when pushing on the accelerator frequently, and especially in reverse, from a stopped position, until you really push hard on the accelerator causing it jump. 3. Last friday 2/21/2014 as I was on a ramp moving from one interstate to another, the engine continued to rev up even after I let off the gas, and pushed the brake. …”
