2004 Chevrolet Trailblazer: brake failure

Filed Jan 17, 2012 · Electrical · 84,000 miles · PA

The speedometer on my 2004 trailblazer operates very erratically. At times it does not work at all at times it registers way slow or way fast. This to me is a major safety issue. If driving on snowy roads you can not tell how fast your wheels are spinning and this could cause loss of control of the vehicle. Or another scenario, traveling on the interstate and the miles per hour is registering between 5 and 10 MPH less that you are actually traveling. This could pose a rear end collision problem as those traveling behind you may not notice that your speed is slower. A properly functioning speedometer is a vital part of being able to drive the vehicle in a safe manner, not only for your safety but for those around you. In searching the internet this seems to be more of a "common" problem than what one might realize. General motors should be held accountable for this problem, as a properly functioning speedometer is an important safety feature. The same as brakes failure, throttle sticking, fire hazard or any other myriad of items on a vehicle are related to the proper and safe operation beyond the operators control. Please look into this. Thank you

Rear brakes failed due to vehicle design flaw resulting in rear driver's side brake hose remaining in contact with emergency brake cable assembly. The brake hose is too short and was either designed, installed or not routed correctly. At highway speeds the loss of the rear brakes in an SUV will potentially result in a crash or a roll over, in an emergency braking situation, with loss of life.

Dt: the contact owns a 2004 chevrolet trailblazer. The vehicle has been to the dealership about 4 or 5 times for the brake system. When a diagnostic test was performed on the vehicle it did not indicate that there was a brake problem. . When the brakes were applied the pedal went to the floor, the vehicle would slow down, but will not stop. No warning lights illuminated ,indicating that there was a problem with the brakes. This did not happen every time that the brakes were applied. The weather condition has no impact on the braking capability. The manufacturer stated that if the diagnostic test showed there was nothing wrong then there was nothing that they could do about the problem.
