GMC Sonoma Problems
The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.

We have just hit 198,000 miles today with no major problems our 14 years together have been good she had 6 miles when I bought her and yes there has been a lot of parts replaced but she only stranded me once when I put a cheap starter on her. she has only had mobile one oil and will run very ruff if she sits for more than 4 days. any way you do the math she is well worth it, and I don't know what I can replace her with when her wheels fall off ( yes I have replaced all four wheel bearing )
