problem #21

Aug 282013

Sierra 1500 4WD 8-cyl

  • 73,268 miles


While slowing to make a turn I applied the brakes and had a sudden and complete loss of brakes. Had I not been on a Suburban road or in traffic or a high speed highway the situation could have been catastrophic and resulted in a crash. I was near my repairing garage and managed to get the vehicle there by using the emergency brake and low speed. It was less than a mile. I had this repaired at a cost of $849.27. Just yesterday (6-30-2014) I was parked on a hill and as I released the parking brake my foot suddenly went to the floor and I experienced a second loss of brakes due to failure of the remaining two brake lines. I was on a hill and had only a tiny amount of braking power. The vehicle is at the garage and the cost of this repair has yet to be determined. They will replace the remaining two brake lines. I recently had to replace the transmission cooling lines which ruptured and are located in a nearby location on the vehicle. All are exposed and un-shielded. The manufacturer advertises that the vehicle is "professional grade" and "heavy duty" but I find both these claims to be great exaggerations. These situations have scared me and I desire to acquire a different vehicle as soon as I am able. Unfortunately, this will not be soon. I will have to drive with the fear that another potentially catastrophic problem could develop at any moment. Fortunately, neither of these incidents were panic stops.

Front ABS speed sensors failed at 26,000 miles. The manufacture said this was due to normal wear and tear, this model year should have 60,000 miles on it. They have reimbursed some owners for this problem and refuse to pay others. No one at GM could explain why both sensors went out at the time.

Brake line failure. Low speed backing up brake pedal went to floor. Brake fluid sprayed on exhaust, producing a lot of smoke.truck was cold, if running longer there could have been a fire. Contacted GM in 2009 about brake line rust and they stated it was normal. Truck had only 32000 miles at time of complaint. Truck now has 58000 miles.

Sierra 1500

  • 72,000 miles


The contact owns a 2006 GMC Sierra 1500. The contact was driving 10 mph when the ABS system activated abnormally and caused an increase in stopping distance when attempting to brake. The ABS warning light did not illuminate to warn the contact of the failure. The vehicle was taken to a local mechanic who advised that the brake drums would need replacing due to debris build up, which was causing the ABS system to provide a faulty reading to activate. The manufacturer suggested taking the vehicle to a dealer for diagnostic testing. The contact believed that the vehicle was unsafe to drive. The failure mileage was 72,000.

At low speed the ABS activates causing extended travel when stopping, which turns out to be very scary for driver and pedestrians in cross walks.

2006 GMC 1500 Sierra with 16,734 miles, the ABS system engages around 5 mph and when the truck will actually stop is any one's guess. Very dangerous in parking lots, and around pedestrians as well as normal driving. I see there are thousands of similar complaints on the web. Please put my tax dollars to work and do something. Thank you.

  • 30,000 miles
The ABS activates when it isn't supposed to. Backing out of my driveway the brake drops, grunts, and takes far too long to stop. Also when turning this occurs. GMC had a recall for the exact same thing for the model years 1999-2002 starting in 2005. They say it's from normal wear and tear, but not one other truck or SUV owner I've ever known has had a similar problem, with a different company. They even offered to pay for part of it, citing the recall accidentally. This is a very dangerous defect, and something needs to be done about it. We don't need to wait until somebody dies. Earlier today while driving it took nearly 5 seconds to stop coming up to a railroad crossing. If I hadn't known about the defect, I may not have been able to stop. Did I mention the vehicle has less than 30,000 miles in its 5 years of operation? companies shouldn't be allowed to wait 6 years to initiate recalls. They obviously know it's a problem. Thanks.

  • 20,000 miles
Improper ABS activation a low speed. Occurs in the last few mph of deceleration at a stop sign or red light. Also occurs when coming to a stop during parking, worse when turning. Pavement is dry. No ABS activation at speeds above 5 mph. Pedal vibrates lightly and becomes softer until complete stop is attained. Very concerned that braking distance is compromised and might impact vehicle in front or stop within intersection.

  • 10,000 miles
Purchased 2006 GMC Sierra 1500 new in April 2006 with 208 msl showing on odometer. At 10,000 miles started getting vibration when applying brakes. Took vehicle into dealer rotors were turned, vibration gone. At about 18,000 miles vibration returned. Took vehicle back to dealer, rotors turned again and tires balanced and rotated. Again smooth braking. At 32,000 mls vibration returned again. Took back to dealer, this time they replaced front brake rotors with new new ones. Brakes smooth again. I now have 44.500 miles and the vibration is back again as bad as ever. Vehicle is now out of warranty. Dealer will not do anything unless I pay. These are highway miles. I am not riding the brakes getting them hot. $30,000 for a pick up truck and GM can"T or won"T fix the problem. I will never by another GM product!!!

  • 50,000 miles
The contact owns a 2006 GMC Sierra 1500. The contact stated that the master cylinder failed on his vehicle. While driving at an unknown speed, the brake pedal extended to the floor and the vehicle failed to stop. The contact rear ended another vehicle. There were no injuries. The front end, hood, and grill were damaged. The vehicle was towed from the scene and returned to the shop it was repaired at three months prior to the crash. The technician stated that the master cylinder was the cause of the failure. The contact has called different GMC dealers and repair shops to purchase a master cylinder, but there are none in stock. It would take a week for the part to arrive so that the repair can be completed. The failure mileage was 50,000.

Down hill at 80mph brakes on my 2006 GMC 1500 caused my steering wheel to shake so hard my heart was in my pants. 18K miles on my truck and had to have my rotors turned and shoes adjusted in rear drums. Sign of global market. Low bidder gets the job to mfg all parts and you guys at NHTSA get a pay X twice a month. NHTSA has two other stories re bad brakes on 2006 GMC 1500. No action until someone get hurt is the word of the day. Ps: I don't drive at 80mph but get fast on ca route 15 or get run over by car/big rigs so you should at all times have perfect brakes and worry about the other small stuff.pls call GM and tell them my life is in their hands and in the coming years no more GM products for me if they can't mfg a brake system that can go more then 18K. Navy aircraft I landed had brake rotors that would turn red from heat but did not need a change out after 200 landings. X it out NHTSA the next person you save maybe your son or his friend.
