One problem related to turn signal has been reported for the 2001 GMC Jimmy. The most recently reported issues are listed below.
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.
