Problems with 2002 GMC Sierra 1500 EQUIPMENT

I have had to replace front wheel abs speed sensors and related parts twice on my 2002 gmc sierra 1500. the first time was in 2006, the second just this week. the truck has just over 86000 miles. the abs engaged below 10 mph. i almost hit other cars or objects several times when this occurred. speed sensors were corroded. hub bearings were also replaced due to speed ring faults. it has cost me over $1500 both times to have this work done to make my truck safe to drive. my request for warranty coverage was denied. *tr

At 68,994 miles my truck lost 2nd gear, drive, overdrive and reverse. a new reaction shell was installed. at 90,027 miles and 360 days later the same problem occurred and a beast heavy duty reaction shell was available and installed. *jb

2002 gmc sierra 1500 p/u w/4.3 lt. v-6, i have had to have the a/c condensation line covered three times with the foam insulation from my dealer. they also have to clean the corrosion from the distributor, remove the screen in the bottom of the distributor, clean the spark plugs and replace the cap and rotor on each occasion. my truck is currently in the shop again to have the distributor replaced. this is at a cost of around $680.00 to replace the distributor , new plugs due to fouling and wires. i have spoken with general motors and to the dealer several times regarding the temporary fix (band-aid). the air condition condensation line is located directly above the distributor and they refuse to move it. it has become increasingly apparent their repair is not a fix but a temporary solution to get you out of warranty. there has been a recall sent to me but does not show in your listings for the subject vehicle. this problem is very dangerous, your vehicle usually gives no signs before leaving you stranded in the middle of the highway. my question is why the dealer gets away with a temporary fix and not a resolution to the problem ? i believe the air condition condenser line should be relocated away from the distributor altogether. gmc is well aware of this problem and rectified the re-engineering of the a/c line route in the 2003 models. *nm
