Filed Jan 15, 2004 · Brakes, Seat belts · 1,500 miles · CA

#1 transmission. Slips out of gear into nuetral while driving at highway speeds. Must coast over to side of road, turn off engine, wait, restart and continue on. Narrowly caused a collision with a semi truck while coasting to side of road. Complained to dealer numerous times, said they could not find anything wrong. Now trans is locked in 2nd gear and won't shift to a higher gear. #2 paint. Started chipping within 6 months old and less than 2500 miles. Dealers said nothing could be done. Roof is now rusted through and headliner is hanging down. Dealer and zone rep say gmc is not responsible and refuse to repair and repaint. #3 seat belt retractor. Driver's seat belt will not retract and is very loose. It would not prevent injury or death if involved in a crash. Dealer and zone rep deny responsibility and refuse to repair except at my expense. #4 radio. Radio has been replaced 3 times by the dealer since new and they refuse to replace or repair it again. Volume must be turned up all the way to be heard. This is the exact same problem with every radio they say they have replaced.

1) dash brake light constantly on or flashing, code = shorted ABS defective? 2) 4wd transaxle- shifter fork and thrust bearings broken. No forward or reverse on highway-very dangerous breakdown 3) ECM electronic control module failure, preventing the 3-4 overdrive shift in the transmission-very high RPM under load. 4) automatic transmission, no reverse due to loss of planetary gear set (2) due to defective workmanship (drift pin setting gear in hub had worked out thereby galling and milling out the hub area=loss of pressure and bearing stability. 5) nylon rocker arm retainers had fractured and broken due to defective materials, allows rocker to fall off rocker arm shaft and push rods to fall into crankshaft...abrubt engine halt at high speed...very dangerous. 6) glow plug controller does not activate the glow plugs after hot engine sits for about 15 minutes...engine will not start.

The windshield wipers will stop in mid stroke and stay there for an extended period of time before resuming. Newer models have been recalled, but the '93 gmc has always had the same problem. The egr valve tends to stick open. It has been cleaned and/or replaced several times, and it's a safety issue because it drastically lowers manifold vacuum and that effects the power brakes.
