2002 GMC Sonoma Reviews

Have had the Ext Cab V6 engine model since new (now 91,000 miles). Now have problem with ABS LIGHT on dash - no one knows what to do to fix it. Have replaced the 3rd door latch 3 times - running lights go off when direction signal is on - but seems everyone has the same problem and GM does nothing to remedy it. Do routine maintenance and it will run forever, I hope. Would rather spend a couple hundred dollars a year for maintenance than to incur a $350 a month car payment.

I have a 02 GMC Sonoma and the passager side cab is rusting. The thired door handle broken because its plastic. Its automatic and some times when shifting it does not seem like it wants to shift. The daytime running lights work but when I turn on the turn signial they go out until the turn signial goes out.

A door pin was replaced and then the third door was readjusted and wind noise is gone. Have problems with seat belt on occasion not retracking properly. Still get antifreeze smell on certain dial settings.

The truck has developed wind noise on the drivers side door upper right. Had trouble keeping the antenna screwed on but I think the dealer took care of that. Tried E-85 fuel but truck ran terrible and it sucked up the e-85 like it was nothing. Get much better power from gasoline. Don't particularly like the double door as the doors tends to move when traveling over the cities's bumpy roads. I get an anifreeze smell when heater is on max setting in about 7 minutes but if I turn the setting down there is no smell.
