An accident has not occurred yet, but it something I'm concerned deeply about. Awhile back there was a recall on the instrument cluster of the gmc Sierra 1500 (possibly othets on the list, im sure). I did wind up having the cluster replaced, there didn't seem to be any issues at the time. Now...the replacement cluster has gone haywire. I notice no issues with operations at this time. But the cluster doesn't register certain things or it fluctuates on and off, or doesn't read correctly at all. Is it possible that the replacement could have been bad as well?

Hydraulic brake lines corroded causing leaks and brake failure

76000 miles; issue ongoing beginning in november 2018 on dry pavement at low speed (under 10 MPH) braking is compromised by ABS system engagement issue. Below 10 MPH, the ABS system engages causing dry pavement braking to be double or triple the normal distance to stop prior to the ABS issue. This is a safety issue since ABS system pulsing of the brakes at slow speeds on dry pavement is unexpected. At a stop sign/crosswalk, this has caused a very close encounter. Vehicle has less than 80000 miles and has been serviced routinely by a certified mechanic. Replacement/service of ABS speed sensors and rust issue did not correct the problem. I have never been contacted regarding the recall that exists for this issue. Require assistance to determine why a vehicle with this mileage has this obvious safety issue and gm has provided no relief.

While driving approximately 35 MPH in town, the vehicle in front of me signaled to make a left hand turn. I began to slow down the vehicle and then I lost all brake pressure. I was unable to stop the truck to avoid an accident due to complete brake failure! There were no previous lights or warning signals notifying of a brake problem prior to this. The warning light came on after the accident. The brake fluid reservoir was full. After further investigation, it appears that the brake lines were corroded causing the brake failure.

Tl* the contact owns a 2003 gmc sierra 1500. While driving approximately 15 MPH in a parking lot, the contact slammed on the brake pedal to avoid another vehicle that abruptly pulled in front of his vehicle. The brake pedal traveled to the floor without stopping the vehicle immediately. There were no warning indicators illuminated. The dealer was not called; however, the contact spoke to a technician who stated that he could repair the failure by cutting out the rotted section of the brake line and replacing it with a new section. The failure was not diagnosed or repaired. The manufacturer was made aware of the failure and did not assist. The failure mileage was 127,600. The VIN was not available.

Loss of brakes due to rusted through brake lines. While pulling a trailer with pontoon boat, all of a sudden when stopping I suddenly had no brakes. Just came off the freeway but was going slow when the failure occurred. Need to replace now. Also, rusted through power steering lines. Already replaced. Also, rusted trans cooler lines. Will need to replace soon.

My 2003 gmc sierra 1500 presently has 67,631 miles on it. With about 46,000 miles on my truck at the end of 2011, I noticed low coolant, but could not find a noticeable leak. I continued to add coolant, but could never find the leak. While having my oil changed in june 2016, the dealer (where vehicle had been purchased and serviced) said coolant had leaked into the oil due to a cracked cylinder head, and estimated approx $3500 to fix it. In dec 2016, they recommended replacing the engine at $6600. In researching this problem, I found gm service bulletin #06-06-01-019b, 12 june 2007, subject information on gradual coolant loss over time with no evidence of leak found. It discusses a known manufacturing defect with castech heads used in the 5.3l vortec engine as I have in my truck. Subsequent online searches indicated this was a common problem among such gm engines. I went back to the dealer with the service bulletin and asked what gm would do to assist in the repair of this known manufacturing defect. The dealer said the vehicle wasn't under warranty so they wouldn't do help. I requested assistance through the gm regional rep, and was also told they would do nothing. In march 2017, I wrote a letter to gm customer assistance center requesting assistance. Gm responded with a letter two weeks later stating that for service request number 8-2815264552, they "cannot provide any cost assistance on the engine issue on the vehicle." further they stated there is no recall or special coverage for the issue. The faulty casting of the castech cylinder head in the 5.3l vortec engine is a known defect in about 5 years of gm vehicles which gm refuses to acknowledge to customers, but clearly acknowledges through its service bulletin. Gm should provide a recall or at least financial assistance to correct this known defect.

Tl* the contact owns a 2003 gmc sierra 1500. The contact observed an abnormal sound from the rear brakes without warning. The contact took the vehicle to the local dealer (betten baker gmc located at 749 w main st, lowell, mi, 49331) where it was diagnosed that the rear brakes had failed. The vehicle was repaired. Two weeks later, the contact observed a puddle under the front driver door and realized it was brake fluid. In addition, the contact observed that the paint on the frame was failing and was wet due to the excessive leakage of the brake fluid. The contact researched online to see the complaints on his vehicle and found a closed investigation due to brake line corrosion under the federal safety agency action number: ea11001 (brakes). The vehicle was not diagnosed again. The manufacturer was not made aware of the failure of the failure. The failure mileage was approximately 117,000.
