| Bought my truck new in 2004 as my retirement vehicle. i have only 42,000 miles. i had my instrument cluster replaced two years ago under a dealer warranty due to a defective speedometer. within the past week my transmission has randomly slipped from a dead stop as well as double clunked from a dead stop. most recently, the ac is randomly blowing out hot air. i should have bought a golf cart instead. since the truck is now 7+ years old it is no longer under warranty. i'm hoping the transmission does not completely shut down and leave me stranded while driving down the freeway on a hot summer day. note: i was a victim of the us fidelis extended warranty scam. | |||

| In december 2008 i contacted general motors regarding a continuous backlash that had developed in the drive train of my 2004 chevrolet 4wd pickup truck when the automatic transmission shifted gears along with loud clicking noises that were coming from the speedometer/dash gauges . they advised me to take the truck into a chevrolet dealer for inspection. in doing so, the dealer replaced the instrument panel cluster on my truck under some settlement that other parties had reached earlier with general motors resulting in extended special coverage. on the issue of the continuous backlash in the drive train however, the dealer merely provided me with a bulletin from general motors stating that the clunk noise i was experiencing was in their words a normal condition and no repairs should be attempted. there is no way that this condition can be considered normal and i feel that general motors is attempting to escape their responsibility for what i believe to be the manufacture and sale of a now known defective product. i further believe this defect to be wide spread among their truck and car manufacturing lines and extending over several model years of vehicles. my truck has only 19,000 miles on it when i first noticed this problem and i believe that it can only get worse as time goes by eventually leading to a complete failure in the drive line components of my truck. please add my voice to what must be a long line of consumer complaints toward general motors regarding this problem. your help in seeking remedy for consumers like me and others in this corporate failure by general motors would be greatly appreciated. thank you and please advise me of the action taken. *tr | |||

| Speedometer drive motor failure, 2004 chevrolet 1500 pu. when drive motor fails the speedometer will freeze at a random speed. since the speedometer is stuck, you must calculate your speed from a start position of where it was stuck. example: if the speedometer is stuck at 70 mph, and your desired speed is 45 mph. your speedometer will read 115 mph. if your desired speed is 70 mph, your speedometer will peg out at 110 mph. if you are not aware that the speedometer is stuck when reducing your speed, you could panic, and attempt to reduce speed too rapidly potentially causing a rear end accident. when driving through multiple speed zones you have to constantly calculate your speed, assuming that the speedometer is tracking accurately. in order to fix the problem, the entire instrument cluster must be replaced. my cost was $386.00. the speedometer will slowly reset, each time the vehicle is started, by 5 mph. gm customer service acknowledged this as a frequent problem, yet refused to acknowledge it as a safety issue. the local dealer where i bought the truck said they replace 3-4 per month. where i had the repair made, they have established a vendor that does it so routinely they have a 24 hour exchange turn-around.*ak | |||
