hello all.. i have my FJ for only 4 days and when i press on the brake it stops then it accelerates...also my brake makes a noise in the interior of the car when pressed... another thing is i know you arenot supposed to drive it in 4 d so obviously D is used.. in D the car hesitates in first gear and when i stop and then press the accerator, the transmission jumps and kicks the car back... has anyone had any of these problems? i love the car but now i dont want it and its a shame cause ive had it not long at all. its a 2008 with 25,000 miles.. any info would help. thanks
