Four problems related to service brakes have been reported for the 2008 GMC Envoy. The most recently reported issues are listed below.
This is a very unsafe vehicle. I purchased it for my husband and have seldom drove until recently when he was injured driving it. He drove through our garage and demolished it. I how drive it and find the brake and gas pedals the worst problem. No matter what shoes or boots you are wearing you cannot control the vehicle. It has cost us thousands in damage and repairs. I do not have pictures, but will obtain them and forward them. The car was just pulling up to be parked outside by out garage when the problem occured. The weather was fine-August 2017. It was just getting dark. This vehicle should be taken off the road ASAP until it is repaired or replaced by GMC. My son drives a used GMC and it has none of these problems. The picture I am sending you is of jack benjamin blazek, a technician at bretting manufacturing, inc. In ashland. Ben has also built dirt track race cars and I have built john deere combines.
"takata recall" when I first start the car and begin to accelerate the traction control system activates causing lose of power - very dangerous when pulling out into traffic. I have to disengage the system on the shift handle to prevent this from happening. I am also experiencing the abs problem of activation when coming to a stop in all conditions. It is already a recall for GMC vehicles up to 2004 but obviously not corrected. The traction control system activates every time after first starting the car. The abs system is sporatic. No warning that it is about to happen. These systems fail daily without exception.
Abs activates for no reason. It happens at slow speeds when I am coming to a stop. It happens all the time.
The brakes on our GMC Envoy "skip" when there is wet weather, bumpy roads and especially snow. When trying to brake, the brakes don't seem to grab and it takes extra long to stop. We haven't had any crashes, but several close calls due to the brakes not engaging. In dry and normal weather, they work fine.
