I have really enjoyed my Sonoma. It has been a very reliable truck with minimal problems. It has over 130,000 miles now and is still running strong as when I bought it. The only problem I have had is with the EGR on the engine, but they say it is a common problem with it.
I purchased this truck new, if now has 211,000 miles without a major repair. While it has been well cared for mechanically, I have hauled countless loads of lumber, mulch, bricks, furniture, you name it. Off-road, it is tough to match, I have reached many fishing spots that would not have been accessible by a lesser vehicle, and some harsh Pennsylvania winters seemed paltry behind the wheel. I was actually asked by a collague if my truck was new after it had crossed the 200K mark. Power is ample (and I sold my 69 camaro SS to but this truck, so that is quite a statement.) All repairs have been electronic, it has never left me stranded.
I purchased this truck with 33,000 miles and it has 90,000 now. The only complaint I have is the size. I really need more room for the family. The H.O. 4.3 in the 4X4 is one of the most powerful V6 motors put in a truck today and with out a doubt one of the most dependable. ZERO mechanical break downs. Only a few electrical issues. I have towed or hauled everything with this truck from loads of lumber and bags of concrete to a 22 ft pontoon boat. This is One Tough Truck
This has been a wonderful little truck. It has been used as a courier vehicle for the past 4 out of 5 yrs that I have owned it. Still going great. Replaced the clutch & starter. Then the engine at 210,000 because of timeing belt. Body has held up great. A/C compressor went out at 200,000. It has carried average of 40,000 per yr in miles and with the newer/used engine will last another 100,000.
This has been an excellent vehicle for my use. Good performance and fun to drive. Normal maintanance only for brakes and tires and service. Only major maintenance need was air conditioning leak. Average in excess of 20 mpg.
