ON 09/27/19 WHILE DRIVING MY VEHICLE HOME FROM DINNER WITH MY CHILDREN MY BRAKES WENT OUT COMPLETELY CLOSE TO A MILE FROM OUR HOME. THE VEHICLE WAS IN MOTION WHILE THIS HAPPENED AND WE WERE ON A HIGHWAY. SIGNIFICANT FORCE HAD TO BE EXERTED ON THE BRAKE PEDAL TO FORCE THE TRUCK TO SLOWLY COME TO A STOP. HAD WE BEEN IN HEAVIER TRAFFIC THERE IS NO DOUBT THAT THIS BRAKE VACUUM PUMP FAILURE WOULD HAVE RESULTED IN A CRASH INVOLVING OTHER VEHICLES. WHEN I CONTACTED THE DEALERSHIP, RICHARD KAY SUPERSTORE IN ANDERSON SC, THEY STATED THEIR WAS A RECALL FOR A RE-CALIBRATION OF THE BRAKING SYSTEM THAT IF LEFT UNCHECKED COULD CAUSE A FAILURE OF THE VACUUM PUMP. AT THE TIME THE VEHICLE WAS THREE YEARS OLD AND THE RECALL WAS ISSUED 25 DAYS PRIOR TO MY INCIDENT. THE TOTAL COST TO REPAIR THE VACUUM PUMP WAS $705.96. I AM VERY DISAPPOINTED THAT CHEVROLET HAS NOT RECALLED THE VACUUM PUMP ASSEMBLY. IT IS CLEAR TO ME THAT THE CALIBRATION FAILURE IS CAUSING THESE PUMPS TO WEAR OUT TOO QUICKLY... OR THE PUMP THEMSELVES MAY ACTUALLY BE FAULTY AS WELL. REGARDLESS, THE CALIBRATION SHOULD BE REQUIRED AS WELL AS A REPLACEMENT OF THE VACUUM PUMP AT NO CHARGE TO THE CONSUMER. THIS WILL PREVENT INJURY AND POTENTIALLY THE LOSS OF LIFE.

THE TRUCK HAS UNDER 35,XXX MILES AND JUST HIT ONLY 4 YEARS OLD IN AGE. I CONTACTED GM TO SEE IF THEY COULD HELP ME AS THE BODY SHOP EXPRESSED THERE HAS BEEN OTHER GM TRUCKS IN TOWN WITH THE SAME ISSUE THAT HAVE REPORTED THE EXACT SAME PROBLEM RECENTLY. I CALLED 3 DIFFERENT PEOPLE AT GM TO SEEK HELP WITH WARRANTY OR ANY COVERAGE TO HELP WITH THE PROBLEM BUT THEY ALL EXPRESSED THERE WAS NO HELP.

WARRANTY ENDED IN JULY 2019. CHECK ENGINE LIGHT CAME ON IN NOV 2019 WITH A P050D CODE. VEHICLE ONLY HAS 32,0000 MILES. TOOK IT TO DEALERSHIP (AUTONATION CHEVROLET IN GILBERT, AZ) AND WAS TOLD TWO FUEL INJECTORS WERE THE CAUSE AND NEEDED REPLACED. THE DEALERSHIP SAID ONE OF THE INJECTOR FUEL RODS AND GASKET WAS INSTALLED BACKWARDS AT THE FACTORY. I PUSHED FOR GM TO PAY FOR THE REPAIR SINCE NO PREVIOUS INJECTOR WORK HAD BEEN DONE. THE EXCEPTION WAS CLEANING THE INJECTORS AS PART OF ROUTINE MAINTENANCE, WHICH OCCURRED IN AUG 2019 AND WAS COMPLETED AT DEALERSHIP. GM AGREED TO PAY HALF THE COST OF REPAIR. HOWEVER, I WHOLEHEARTEDLY BELIEVE THEY SHOULD'VE PAID THE ENTIRE COST SINCE THIS WAS CAUSED BY A FACTORY DEFECT. I BELIEVE THIS SHOULD BE LOOKED INTO BECAUSE IF MY INJECTORS WERE INSTALLED INCORRECTLY AT THE FACTORY, CHANCES ARE OTHER VEHICLES HAVE THEM INSTALLED INCORRECTLY AS WELL.

THE PROBLEM GOT WORSE CAUSING TWO LOW SPEED ACCIDENTS WITH NO DAMAGE BUT SCARY. NOTE I HAVE TWO KIDS IN THE CAR. BEEN IN FOR MULTIPLE RECALLS. ONE ACCIDENT HAPPENED IN A DRIVE THRU AND ONE IN MY DRIVEWAY. BOTH WERE FRONT END COLLISIONS BUT NO DAMAGE. SECOND THE TRUCK SHAKES AT HIGHER SPEEDS.STARTING AT 24MPH UP TO 80. MY KIDS TEETH SHATTER IN THE BACK. THAT'S HOW BAD IT IS. DEALERS SAID THERE IS NO FIX FOR THAT SO I STARTED BY RE BALANCING MY TIRES AND AFTER THAT DIDN'T WORK I GOT NEW TIRES. STILL HAVE THE ISSUE AND ITS MORE OF A HEADACHE TO BRING IT INTO THE DEALER CAUSE THEY DON'T WANT TO FIX IT OR CAN'T. CURRENTLY ON 40,000 MILES ON MY TRUCK AND ALREADY HAD A MULTITUDE OF ISSUES WITH OIL PUMP FAILURE, STEERING COLUMN REPLACED DUE TO MOVING HORIZONTAL. SEAT ISSUES THEY COULDN'T FIX SO HAD TO REPLACE THE BRACKET AND BRAKES ARE ONGOING.

If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Consequence & remedy

General Motors LLC (GM) is recalling certain 2015-2016 Chevrolet Silverado 1500 and Tahoe Police Pursuit and Special-Service vehicles.

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence & remedy
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced.

General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.

1PE18012 · 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.
