“Don't have my VIN handy at the moment b/c my truck is in the shop having $1400 of transmission work done on it. It's a 1998 Gmc Sierra 2wd, and the transmission went out 8/21/03. The tranny had 84,000 miles before comlete failure. The truck was driven by an exceptionally gentle driver, never used for towing (even though it came with a towing "package") and never abused in any way. Yesterday, it wouldn't reverse or go into 1st gear. Two weeks prior it began shifting hard, emitting a loud "clank" sound...we knew the end was near!”

“The consumer stated that while driving there's was a sizzling noise coming from the engine compartment. The plastic or cellophane sealant strip for the carburetor gasket located between the carburetor and throttle came unsealed and fell off. This caused gasoline to pour out onto the engine block. This could have resulted in a fire of explosion in the engine block. Please provide more detail information.”

“Windshield wiper partial failure. Works sometimes...sometimes not. Perhaps a short in the switch. Steering problem is hard to discribe. At low engine RPM's, expecially at idle its as if there is no power steering at all. Steering wheel is extremely hard to turn. Then, at road speed, at times when youturn the wheel to about the two o'clock position the steering wheel will suddenly loose all 'feel' and will 'fall' to about the four o'clock position. The steering is still operational as the truck will veer if you don't catch it first and correct. …”
