“Service engine light has come on a total of 7 times in 8 weeks (all with in 2 months). I was told by dealer secondary air pump was bad. Part was replaced a number of times. I called GM's customer assistance center. They offered no help other than to call a Gmc dealer and have them take a look.”
NHTSA complaint #10075391, filed 2004-06, 40,000 miles“Really bad exhaust smell. Not eggs. Not your standard stink. Bad smell since 6 months after purchase in 2001. Keeps the following traffic way behind me. Had oxygen sensor checked many times. But I think its the cat. Converter. Everytime I take it in for service, I request a fix. Still not fixed. Service center can't dup problem, why? I smell it !! Also flux gas gauge movement in park. Also no horn. Had fixed once in summer 2005, and 5 months later it doesn't work again. The fuse is fine. Could have used it the other day. :-(”
NHTSA complaint #10142264, filed 2005-11, 5,000 miles“Was told by state farm this was a design defect. The oil lines leak from the engine down to the filter that is on the front bumper instead of on the engine.”
NHTSA complaint #10098681, filed 2004-11, 28,000 miles“Problems with my 2001 Gmc Jimmy have been numerous including ignition switch, wheel bearings, clanking noise, roaring noise, windshield wiper failure, windshield wiper hose failure, battery, A/C, and so on. Currently, my vehicle clanks approximately 15 minutes after turning off the engine and my A/C does not work properly at all times. Dealership consistently says there's nothing wrong however I have had the vehicle for 2+ years and I know my car.”
NHTSA complaint #10042970, filed 2003-10“My vehicle has two problems that I am aware of. There's heat coming from the floor heater while the heater is off, and it burns my feet. The other problem is that when I activate my left/right blinker my day lights go out, and sometimes when I'm driving my day lights are not activated. I have to play with my blinkers to make then come on. My car is still under warranty, but the dealership where I purchased this vehicle refuses to fix either problem. They told me that my car is designed this way.”
