I have 259,000 miles on this truck not 1 major issue. I just put on a water pump last month and the starter has started to act up, I think after this many miles and 13 years these should be wearing out. I have had some suppension problems but that I think is more related to driving on the pothole covered roads in Michigan more than the truck. I don't see any issues coming up that will keep me fromsurpassing the 300,000 mile mark.
One tough ole bird! Bought the truck in 2000 with 96K miles from my brother. Got 215K out of her before I put her up for sale. Various maintenance items replaced along the way, water pump at 118K, clutch at 126K, alternator at 127K, fuel pump at 179K, radiator at 214K due a cracked tank. Never had to go into the motor. Origional timing chain was still in service when it sold! Truck had tow package with engine oil cooler. I think that and a healthy diet of Amsoil and Mobil 1 greatly contributed to truck's longevity. Would buy another one in a minute!
Replaced 3 starters, cooling fan, radiator, 3 fly wheels, Air condition compressor, transmission at 122,000 miles, catalitic converter just to name some of the problems. The driver's seat stop working at 70,000 miles. The vehicle is not built for a large amount of
I purchased my used sonoma with 4,000 miles. Within the first year of owning my truck I visited the GMC dealer for the replacement of my rear axis, starter, carberator, clusters board, various fuses, breaking system, anti-lock breaks, wiper blade motor, leaking hose for air condition system, leaking hose for exhaust system and other minor repairs. My thoughts were that the prior owner damaged the truck before resaling, because after those parts were replaced (free of charge) my truck is running fine.
