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. This is not the first occurrence of this, it's actually happened at least 10-12 times. It was definitely the most scary, as I thought I was going over the side of the ramp or into the semi in front of me for a minute or so. 4. the brakes squeak loudly when it's cold. 5. the brakes are either really sensitive, or you have to stomp them to get them to work, so since you don't know which it's going to be you're likely to jerk yourself and your passengers around a lot. 6. the vehicle pulls to one side or the other, which would seem to indicate that an alignment is needed, however, it can't pick which side it's going to gravitate towards which leads me to believe it's something in the steering.
