The front brake shoes on an 2004 Envoy has been replaced every year since 2007. Will not wear evenly and causes the front end to vibrate when applying the brakes.

Bought the car 2006 was two years at that time less than a week into replaced brakes for ABS failure. Still happening, took it back said everything was normal. Well about two weeks ago my wife was going up-hill to a stop light hit the brakes on slick pavement and the brakes locked up and ABS did not kick in. Causing my wife to total two vehicles that I am now being sued for one of them.

Bought "certified used" Envoy in October of 07. Transmission completely stopped at 57K miles 3 months after purchase. Check engine light comes on and off every couple days(have video, but sandy sansing of pensacola Florida says there nothing wrong) vehicle jerks at stops and starts. After 3 trips to dealership w/ "nothing wrong" they finally decided that a O2 sensor was bad at 71K. Envoy had been back in the shop at a cost of $80 bucks twice since then because of the "check engine" light and the brakes are failing, the "ABS brake" light doesn't come on so they say it cant be the brakes. When trying to stop the brakes stop working and a second later they will catch and begin to stop vehicle, as if the brake system is obstructed and skips a few times. The check engine light flashes for those few seconds but doesn't stay on long and they say it isn't throwing any codes. Problem doesn't happen everyday so the dealership has said its a unfounded problem. The thermostats assembly with other parts have been replaced. Have all receipts and dates that I've taken this pos into the dealership. I will never buy another GMC vehicle. I have a 10 year old pickup truck also and has only been in the shop once. There's no excuse that we are driving these (expensive) unsafe vehicles!!

I bought my GMC Envoy in January 2004 for approx. $42,000. This car has everything. After about 2 months of the purchase, my gps went out and had been fixed twice. My brakes do not always work --sometimes they slip especially when I need them most -which is scary. GMC said that they have heard about this problem before, but did nothing to resolve the problem. The engine stalls periodically. GMC said they do not know why. The gas gauge and odometer do not work properly. When I brought my vehicle into North county GMC dealership in san diego for repairs I mentioned my gas gauge did not work along with many of the other issues. After they repaired the odometer by replacing the cluster, the gas gauge still did not work. Every single time these problems happen I am forced to pay a $100 service charge just so they can look at it and because I am in sales, I am also forced to get a rental car. After all this, I am still quite displeased with GMC. I hate to say it but they are supposed to be the best american car "?professional grade?" and if this is true I will never buy an american vehicle again. GMC said they would be checking on all these problems and every single time I picked my Envoy up after they supposedly fixed the problems, I found several issues still unresolved. They suggest I need to set another meeting to bring my Envoy in and of course will cost another $100.
