I have had this truck for only one year and have had many problems. First the transmission went beacause it would not go past 2nd gear and the overdrive light was flashing. It was found to be internal parts and external wiring of the transmission. That same day the alternator went and left me with a dead battery. I have taken it into the dealer about 3 times for rough idle and have been turned away saying the cannot feel anything and that not to worry because its still under warranty. Twice I have taken it in for the front suspension due to a vibration to the steering wheel and truck. All rotors were turned and the front was reallined. Also the truck seems to go through gas a bit too quickly, just about a bit over a quarter tank for every 10-15 miles.
