Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Brake rotors warped at 15K miles, had them turned under warranty at dealer vehicle was purchased from. At 30K miles rotors warped again, this time 1 brake pad was worn down to 2mm thick, the rest appear almost new in thickness. Dealer turned rotors again and replaced pads for $200. Requested and was denied that the brake work be covered under warranty by dealer and GM cs. I took old brake hardware home with me and still have it. I contend there is something wrong with the design or materials in the brake system of this truck causing premature wear and failure of "non warranty" brake items such as the pads and rotors. I contend that there has been a hanging brake pad causing the rotors to overheat and warp since the vehicle was new and any work performed at the time of the 15K mile rotor turning did not correct the problem. If brake work needs to be performed on this truck every 15K miles there is a reason that should be covered under warranty. One time freak failure I can see, two times evenly spaced at 15K mile intervals and I think something is wrong with the vehicles brakes design and/or materials. Vehicle is daily driver, 15 miles a day to and from work. Garaged during the winter, taken off road (frozen cornfields, dirt field roads) for a week in late fall. Used to tow a fishing boat a few times a year. Owner is a former ase certified mechanic and is not an aggressive user of the brakes. Meaning I brake firmly and evenly when braking is needed, lifting my foot off the pedal once stopped and apply only enough pressure to hold vehicle still.

2008 GMC Sierra 1500 sle has had to have front rotors and pads replaced at 20,000 miles. Replaced rotors and pads with aftermarket parts. At 30,000 miles pads and rotors are worn down to metal again. Dealership stated that calipers are working but rear brakes need to be replaced also. I have always had brake issues since the day I bought the truck brand new with brakes overheating.

09/2009 ¿ began to hear front brakes intermittently squeaking when I applied brakes. 10/2009 - took vehicle to midas for inspection. Technician discovered both front and rear brakes were worn down needed to be replaced, truck had approximately 19,000 miles paid for both front and rear brakes to be replaced. 2/2010 ¿ went to local mountains (big bear) for the day with my family. While coming down the mountain I noticed my brake pedal starting to get soft. Pulled over onto a turn our point and noticed my front driver's side wheel was smoking. Please my hands close to the wheel and felt heat coming from the brakes, did the same on the passenger's side with the same results. Waited 30-40 minutes for them to cool down. Tested braking in the turn our and proceeded home. 2/2010 (the next day) ¿ took truck back to midas (with approximately 24,000 miles) for them to inspect. The technician noticed the disk were ¿blue¿ and recommend they be replaced. He also showed me the rubber boots that were melted on the drivers side due to the extreme heat that was generated. I requested that midas change the brakes (which they did) and purchased new rotors as the technician had advised and they also exchanged the brake fluid. I had planned on taking the truck to the dealer to have the driver's side caliper replaced. 2/2010 (the following weekend) I took the vehicle to foothill ranch Chevrolet and explained the events leading up to my visit. I explained to the service advisor that the driver's side caliper boots were burnt and I wanted them replaced. He noticed my concerns and took my vehicle. 2/2010 ¿ (the following Wednesday) received call truck was ready and picked up and that my caliper had not been replaced as it was found to be in acceptable working order even with burnt boots. 3/2010 ¿ called 800-222-1020 (GM customer line) incident # 71-814348680 to lodge a complaint and ask for my drivers side caliper to be replaced.

The contact owns a 2008 GMC Sierra 1500. While driving 30 mph, the contact rear ended another vehicle due to faulty brakes. A police report was filed. The dealer was notified and stated that they were not aware of the failure. The contact found out that the brakes were faulty from the mechanic. The dealer wants the contact to pay for the repair, although the vehicle had faulty brakes at the time of purchase. The current mileage was 850 and failure mileage was 21.

I have purchased a new 2008 GMC Sierra 1500 pickup on March 1 2008 and currently has 10, 400 miles on the vehicle. I have pouncing and vibrating brakes and had them checked at a GM dealer in my town, the brake rotor have measurements of 1.17 and 1.16 left, it is recommended that rotors be replaced at a measurement of 1.1. vehicle iis not safe to operate with rotors in this condition and have to be manufactures defect to be in this condition already. The vehicle as at a registered GM dealership in ligonier pa but this dealer is a Buick and Pontiac dealer and does not sell GMC trucks. GMC will not honor the warranty at this location and this results in my operating a vehicle that is not safe. This is a combination of GM arrogance in policy and the installment of inferior brake rotors to begin with.
