| 2001 4wd 4.3 gmc sonoma, 53k miles, no known events leading to failure, without warning transmission failure, loss of first gear and reverse, almost caused accident do to unexpected deceleration. i have replaced transfer case (where it was making much noise) but this did not correct problem. by far this truck is not professional grade as their advertising claims! | |||

| I have a 2001 gmc sonoma which was bought new in 2002. the vehicle has 78k miles on it. at first the vehicle would have trouble starting. then the transmission would slip when driven cold. after the service engine light came on, a code indicated that there were two shift solenoid malfunctions. both shift solenoids were replaced. that two days ago. today the truck started up, so the vehicle was assumed safe to drive. i was traveling down a busy road at about 40 mph, with an 18 wheeler tractor trailer behind me, when the vehicle, without any indication of malfunction, shifted from overdrive to first gear (it is an automatic) thus resulting in an engine braking effect wihich slowed the vehicle down to about 25 mph. this was very scary and luckily the vehicles behind me realized that there was a problem and had enough room to slow down. though the problem is not yet known, it seems like there are alot service bulletins for this vehicle and its corporate cousin, the chevy s-10. hopefully, this problem is solved before someone is killed from the failure. i will keep you posted on what parts were replaced/repaired from the dealer. | |||

| I was driving my husbands 2001 gmc sonoma from ohio back to florida when the driveshaft snapped and punctured a hole in the fuel tank and muffler. this event led to us having to replace the rear driveshaft, fuel tank, and he repaired the muffler. we researched gmc driveshaft failures on line and discovered that there were many complaints about the driveshaft breaking. *tr | |||

| There had been a whining(like the old radial tires used to make) noise for about a week and i just figured it was the tires. it got loud on 8/24 and i stopped and put it in park, as i got out to look under the truck, it started rolling and rolled down into the woods, we have filed a police report and reported to the insurance company. we are trying to make arrangements to get the truck out. the drive shaft was lying where the truck was put in park.,,although the park did not hold. the drive shaft twisted and split,,,exploded by the looks of it. i have pictures of the drive shaft. *tr | |||

| Purchased truck in 2006. mileage at 48,000. trouble starting, fuel pump replaced. oil cooling lines replaced. subsequently, automatic transmission slips from 2 wd to 4 wd for no apparent reason. i have noticed that this problem occurs when accelerator is not depressed, and wheels are turned, to turn a corner or to turn into/out of a driveway. usually there is a depression in path as well, i.e. curb/dip at driveway entrance, pothole, etc. engine is not always cold; sometimes shifts at end of trip, sometimes at beginning, no adverse weather conditions. | |||
