When brake pedal was applied it went to the floor. The anti-skid brakes were heard engaging, but brakes did not respond. Consumer had to release the brakes, and apply the pedal again to stop. Dealer couldn't find the problem. *ak
While driving at 45 MPH consumer had to press the brake pedal all the way to the floor , then truck stopped. Dealer fixed problem after the third time.
While driving down the road traveling about 35mph, put foot on brakes and hit a bump in the road, and brakes went straight to the floor. Contacted dealer. Dealer was not able to help. They said brakes were working properly.
Brake system: while driving on avenue at 35-40mph, I crossed a railroad crossing while braking and brake pedal appeared to go to the point of least resistance, or near the floor board. Also, while stopped at intersections, noticed brake pedal very slowly moving to the floor while foot on brake pedal. Immediately took truck to the dealer service dept. And the service dept. Diagnosed it as a leaking master cylinder. The master cylinder was replaced however I still notice brake pedal seeking point of least resistance while crossing railroad crossings and dips/moderate bumps in the road. I feel that this is a safety issue due to the fact that I bought this truck as a family truck and it carries my children on a regular basis. I feel that master cylinder should not have leaked at 822 miles. Other issue>>> highway speed vibrations: truck has had a persistent highway speed vibration (40-45 MPH and 60-70 MPH). The truck was serviced for this problem on sept. 27 and oct. 5. Sept. 27 they balanced the wheels. On oct. 5, they balanced the wheels again and suggested that the wheel weights are "coming off" causing unbalanced tires. Wheel weights have remained intact as of this date but vibration still exist. The vibration feels like it starts at the rear of the truck and migrates through the truck to the steering column and wheel which on occasion has exhibited moderate to heavy shaking including seats and dash. While in turns at times and going over bumps, steering wheel shakes giving the sense of not in control. I feel this is a safety issue since vehicle shakes and vibrates while at highway speeds and something should be done to correct. The gm factory rep. Would like to change the tires to the same brand, goodyear wranglers, however I suggested to him that the truck was in for vibration twice and I suggested swapping tires/wheels to see if this would solve problem and they indicated they did swap but it did not solve problem. This vehicle is not safe.
Vehicle went out of control and hit the median causing injury to driver and passengers because of brake and steering mechanism failure. Yh
While driving down a dirt hill at 3 MPH applied brakes, and the vehicle free wheeled down a hill at 40 MPH due to the ABS system failure. Also, frame is bent.
On loose dirt while traveling down hill brakes let go. The bottom of the truck hit the bottom of the hill, bending the front frame rails and front cross memeber. Driver was traveling about 30-40 MPH when this happened. The problem has been reported to the dealership. Please provide further information.
