Description of the problem | 2014 gmc sierra 1500 denali pick-up truck with 67,900 miles: experienced complete loss of power brakes in stop-n-go traffic situation on highway. Problem started as an rare issue that would correct itself and progressively got worse over a week's time. Issue occurred when in traffic requiring frequent stop-n-go braking. Brake pedal went completely to the floor and stopping distances dramatically increased. Had no way to manually apply the brakes to get them fully engaged. Ultimately forced to shift into neutral and apply parking brake to stop. Subsequently found gm bulletin #pit5361b referring to other customer problems with weak vacuum at brake booster. That problem was confirmed and diagnosed by my automotive professional. Ended up having to replace brake master cylinder, vacuum booster, vacuum pump, vacuum tube/pipe and 2 serpentine belts for a grand total of $1626. 00 in repair work (similar amount to the others i found who experienced this issue). Talked to my gmc dealer who confirmed that this is a recognized issue that hasn't yet risen to the level of a "safety recall". However, i was told "stay tuned" because they wouldn't be surprised if a recall on the power brake system was right around the corner. |
