Two problems related to brake abs warning light have been reported for the 2004 GMC Envoy. The most recently reported issues are listed below.
I just had my brakes serviced and my bushings changed, but my abs light still comes on. Also when I go to brake the car starts to shake and I'm going the speed limit. The engine has a rough idle, and shuts off when at a complete stop and when the vehicle is in motion. I've had many things replaced on the vehicle, such as purge valve, gas cap. Charcoal canister and fuel tank. In the engine the spark plugs were changed as well as the coil packs and the fuel injectors. Along with the camshaft sensor. Still getting p0455 and po0014. Won't pass smog can't register vehicle, but my only means of transportation. 2004 GMC Envoy xuv slt 4dr 2wd.
The abs light stayed on after the fact I had the breaks serviced a few years ago. The airbag light has been on for about a year. Now my break light stopped working, I replaced the fuse and still not working and now the headlamps stopped working. They only work on high beam.
