I have a 2003 Tahoe Z71 with leather seats. My wife noticed a smell and thought it was exhaust. I drove the vehicle and it did not smell that way all the time. We finally found the problem by my wife getting burnt. Her seat heater was getting way too hot and produced a burning smell. It got so hot that it left a burnt mark on the leather seat and burnt her back and that's when we figured out that it was what was causing the smell. Be careful when you turn on those front seat heaters. Will report to Chevrolet.

1. knocking in front end, intermittent steering shaft is out. I have been on waiting list since September 2003 and still not fixed.(in a wreck this component is what keeps the steering rod from projecting into the cab; per Chevrolet mechanic). 2. Sept. 2003 transmission: Grinding/vibrating sound in the middle of vehicle (think this is my torque converter), neutral position from a complete stop and while driving. Been in shop on 2 occasions and still not fixed, mechanic says the vehicle computer doesn't show any problems, so they won't fix it! 3.front differential leaking. Jan. 2004 to be fixed when steering shaft gets fixed! 4. passenger heaters come on by themselves. Nov. 2003 still not fixed 5. front driver's seat won't hold memory settings. Nov. 2003 still not fixed.

Front passenger seat heater comes on by itself. Blinker sensor will tell me that the blinker is on when it isn't. cd/radio lights blink on and off. Rear passenger window rolls down by itself. Fuel guage does not work properly and will often say it's full when it's empty or it's empty when it's full or half a tank when it is empty. Fuel injectors keep clogging up with carbon. Transmission failure from stop and delay acceleration while driving.
