POWER TRAIN - AUTOMATIC TRANSMISSION
06/29/19992006/01/1999
 This suburban has problems with the windshield wipers running for a while then simply stoping for a few minutes, then running again. i am told by gmc this is a known problem but is not covered by a warranty. the wiper pulse module i am told is the defective component in these cases. the transmission slips and occationally leaves a puddle under it if it has been driven for a while. the guages are random in thier readings for oil pressure, temp, and amperes.... the fuel seems to be accurate. other problems are not as obvious but annoying none the less

 Rear differential carrier on my 1993 suburban k1500 broke and locked the rear wheels, form my understanding this is a common occurance on these trucks and gm should be aware of how often these thinsg break and the potential for loss of vehicle control of this happened at high speed.

 I have made sure i have done preventive maintenance to ensure that nothing major would happen . however, i spent $2,600 to replace the rear differntial in 1997 and now after putting the car in reverse on 3/17/00 the rear differential exploded. now the mechanics are telling me that it will cost 4,000 because there are no used idfferentials available because they are all broken. i have spent thousands fixing the rotars, even after getting regular brake inspections. other items i did not report are the three rear passenger seat belts that broke, the door locks constantly get suck and i have to use a screw diriver to unlock them, and it takes two hands to turn the key locks because they are so hard to turn. with all that said, my mjaor concern is why the rear differential just explodes, even after getting my breaks and ar fluids inspected.the suburban is a gmc 1500, sle model k10906. *ak
