| I own a 2006 gmc sierra. i purchased this vehicle from a relative (70 year old woman) and it has 22,000 miles on it. i have just had a mechanical issue begin. when slowing the vehicle to approximately 5 mph, the vehicle abs activates and the truck thrusts forward. i was advised by a mechanic that this is a failure of both front wheel hub assemblies. because this vehicle has so few miles on it i began looking on line for recall information. i am shock how many people have also experienced problems around 20,000 miles, some resulting in crashes. i also learned that the company that manufactures the hub assemblies has issued a recal for the parts unless it was installed by the factory (gm). this isn't right and someone will get injured badly. gm should recall the vehicle. | |||

| Tl*the contact owns a 2006 gmc sierra 1500. while the vehicle was parked on a non-leveled surface, it rolled backwards into a river. a police report was filed. after inspection, the contact concluded that the transmission did not engage itself into park, which allowed the vehicle to shift into reverse. he is in the process of notifying the dealer and the manufacturer. the failure and current mileages were 54,000. updated 5/7/09 *cn updated 05/12/09.*jb | |||

| When the transmission shifts from 2nd to 3rd there is a hard clunking, also when it down shifts from 3rd to 2nd. i have had this 2006 gmc for only 10 months and i purchased it new. i took it to my local dealer for the problem and they told me that this is normal noise for a four wheel drive. i have had many 4x4 gms in the past and not one of them has had this kind of a shifting problem. i have purchased three new gm's in the last 4 years and i have had problems with all of them, i think i'm going to trade it in for a toyota. *jb | |||

| Seats popping noise when weight shifts (start,stop,etc.)first attempt was to replace the seat back. second was to replace the entire seat minus the cover. third time in the service manager wanted to contact the area gm manager for direction. the gm area manager told the service manager to make no repair and direct me to call gm. this truck also has been in for service to the brake rotors to be re surfaced with only 4,600 miles on the truck. the transmission has re calibrated two times one for the lock-up torque converter,and once for a hard shift from first to second gear. the truck has a harder shift now than before. *jb | |||
