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 vehicle when purchased was altered from cloth seats to leather by the dealership where purchased. 3 Days ago my car is signaling me to service airbag while driving the car or in idle. So I immediately took it to a certified mechanic at meineke and was told that this is a manufacturer defect and there is a recall for this on my year, make & model suv. I called gm on 11/29/2019 and was told by a supervisor named angel there has been no recalls by their manufacturer and there is nothing more she can do about the matter. I cannot drive my car like this knowing this can be potentially harmful and hazardous.
I was driving down the road when the car shut down everything I was scared because I had traffic right behind me going 45mph and then they car would not run again. I was right in the middle of an inter section at hall road and 59 it was the scariest thing that has happened to me. I bought this vehicle as a used auto and I'm not sure if the emmission system ever got changed and this happened once before and the dealer said not to drive with my house keys attached. I had to get the auto towed home.
Radiator and transmission went while driving on a highway. My mechanic told me the part that failed never fails and he was shocked that it did.
