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

My dash panel gauges began failing one by one. My headlights will sometimes not come on after starting the car with the headlight switch on auto. A flick of the headlight switch in and off, does not make the headlights come on. Sometimes they come on after driving around, and then will go off without touching the switch. Now, my side brakelights will not operate correctly when the brake pedal is pressed. Only the third brake light illuminates.

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.

While at low speed I press the brakes to stop it goes to stop but then its like the ABS kicks in and releases the brakes then I have to repress the brakes to get it to stop

While driving on a city street the car started lugging and not driving smoothly. When I needed to brake shortly after this happened the brake pedal went to the floor and I had no brakes. I pumped the brakes and was able to stop without hitting any one. I continued about 5 miles continually pumping the brakes not knowing if they would work.during this time the pedal would sometimes go to the floor and other times almost go to the floor. Then as suddenly as it started it stopped. Brakes were back to normal. This happened previously and the GMC mechanic found nothing wrong. So I'm put back on the street risking my life and someone else's because the mechanic said "it sometimes happens". that's not acceptable!

I have owned a GMC all my adult life. This Envoy has been nothing but problems....now the gauges seem to be all screwed up and after reading post from online..I will need to put more time and more money into this SUV. Nothing like driving late at night worried about what's happening now. I go from sitting at a red light and my car losing pressure and turning off, to now every time I get into it and leave my house I hear the door bell and all my panels symbols flash and shows no gas to no battery life.. I am not pleased and will never purchase a GM again..so sad.
