I WAS ON THE RAMP GOING APPROX. 45-50 MPH ACCELERATING TO BE ABLE TO TURN ONTO THE 70 MPH HIGHWAY WHEN MY SUNROOF EXPLODED. IT WAS LIKE A GUN WENT OFF IN MY VEHICLE. IT SCARED ME TO DEATH AS GLASS WAS FALLING ON ME. I SHUT THE INSIDE PROTECTOR AND LOOKED AROUND AND THERE WERE NO PEOPLE, TRUCKS, CARS OR OVERPASS AROUND. THERE IS GLASS ALL OVER THE INSIDE OF MY VEHICLE. THE PIECES CONTINUED TO FALL THE REST OF MY TRIP. I CONTACTED THE DEALERSHIP IMMEDIATELY AND THE GUY SAID HE NEVER HEARD OF IT. GMC HEADQUARTERS WAS NO HELP EITHER. I HAVE READ THIS IS A MANUFACTURER DEFECT.

I AM AFRAID I AM GOING TO GET REAR ENDED WITH MY CHILDREN IN THE CAR. I HAVE SEEN MANY VEHICLE JUST LIKE MINE WITH AT LEAST ONE BRAKE LIGHT OUT. WHEN HE LOOKED THIS UP ONLINE IT IS A KNOWN ISSUE. MY SISTER HAS THE EXACT SAME YEAR MAKE AND MODEL. SHE EXPERIENCED THE EXACT SAME BRAKE LIGHT ISSUES. SHE OPENED A CASE WITH GM AND THEY WORKED WITH HER TO COVER IT AND CHARGED HER THE DEDUCTIBLE. SHE WAS OVER THE 36K MILES GM CONSTANTLY REFERENCES. THIS IS SO UNSAFE. THE AIR ON THIS VEHICLE ALSO DOES LOT STAY COLD. IT TURNS WARM WHEN I SLOW DOWN.

DRIVERS SIDE BRAKE LIGHTS WENT OUT, CAR IS ONLY TWO YEARS OLD. THREE WEEKS LATER PASSENGER SIDE BRAKE LIGHTS WENT OUT. DRIVING ON A HIGHWAY FOR THREE HOURS AS PEOPLE HONKED AND ROLLED THEIR WINDOWS DOWN TO LET US KNOW WE DIDN'T HAVE BRAKE LIGHTS. TOOK TO GET FIXED AND THE LIGHTBULBS, WHICH ARE LED AND SHOULD HAVE LASTED LONGER THAN TWO YEARS, ARE NOT REPLACEABLE, THE ENTIRE TAIL LIGHT ASSEMBLY NEEDS TO BE PURCHASED AT $700 A PIECE. WHEN PEOPLE ARE UNABLE TO AFFORD $1400 BEFORE LABOR THEY WILL DRIVE WITHOUT BRAKE LIGHTS. THIS IS A SERIOUS HAZARD AND A RIDICULOUS MANUFACTURING FLAW TO HAVE LIGHT BULBS THAT ARE NOT REPLACEABLE. GMC SHOULD BE HELD ACCOUNTABLE.

PE18012 · Brake Vacuum Pump Failure
Opened Nov 20, 2018 · Closed Apr 10, 2022
Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Hydraulic; Service Brakes, Hydraulic:power Assist:vacuum
On November 20, 2018, the Office of Defects Investigations (ODI) opened PE18-012 to investigate instances of sudden onset of a hard brake pedal that could result in extended stopping distance due to an issue with the brake assist vacuum pump in model year (MY) 2014 through 2016 GMC Sierra 1500 and Chevrolet Silverado 1500 series pickup trucks and MY 2015 through 2016 Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon SUVs.If the brake assist vacuum pump fails to operate as intended, the amount of brake power assist supplied to the driver can be significantly reduced, extending the subject vehicle stopping distance. GM stated that the root cause of pump failures was due to foreign debris such as oil sludge in the engine oil. GM stated that this debris can become trapped by the oil inlet filter screen. Under normal operation, this screen allows a small amount of oil into the brake vacuum pump. The foreign debris can, over time, clog the pump which can cause a loss of lubrication and a reduction in the amount of vacuum produced leading to a hard pedal and extended stopping distance.On December 13, 2018, GM issued a Special Coverage (N182202780) for the brake vacuum pump issue in MY 2014-2017 trucks and 2015-2017 SUVs on the K2XX platform for 6 years or 72,000 miles. Special Coverage repair includes the replacement of the vacuum pump and vacuum pump belt. Consumers received notification of the coverage via mail. On September 6, 2019, GM notified NHTSA that it was conducting safety recall 19V-645 which reprograms the electronic brake control module (EBCM) and included approximately 3.5 million trucks and SUVs. In October 2019, GM extended the terms of special coverage N182202780 to 10 years or 150,000 miles as well as now including the entire scope of recall 19V-645. In October 2020, GM expanded the scope of coverage N182202780 to include the MY 2018 Escalade and 2019 Tahoe.The remedy implemented in GM recall 19V-645 appears to be sufficient in addressing the safety-related concerns of this issue. Loss of vacuum assist now occurs at a progressive rate as well as there being a more timely warning of a brake problem to the driver through the driver information center (DIC). In view of the recall action and revision to the special coverage, this Preliminary Evaluation is closed. The agency reserves the right to take additional action if warranted by new circumstances. The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.
