Air bags, side/window, curtain, inflatorJul 1, 2021
General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.
A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.
Dealers will replace the left and right side RRAB modules, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on August 18, 2021. Owners will receive a second notice when the remedy is available. Phase I owner notification letters were mailed on May 5, 2022. Phase II owner notification letters are expected to be mailed on May 31, 2022. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020.

Seat belts, frontApr 8, 2021
General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.
A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.
GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.

Service brakes, hydraulic, antilock/traction control/electronic limited slip, wheel speed sensor/tone ringOct 24, 2019
General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. 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.
Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.
As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.

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.
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.

I BOUGHT THIS TRUCK IN DEC.2017 SENSE MARCH/ APRIL OF 2018 I HAVE EXPERIENCED AT LEAST 8 TIMES MAYBE MORE AND JUST LAST WEEK. THE BRAKE PEDAL HAD LOST IT'S POWER ASSIST. THIS SEEMS TO HAPPEN IN VERY CLOSE SLOW SPEED TRAFFIC OR IN PARKING LOTS WHEN PARKING. THE WAY I SOLVE THIS PROBLEM IS TO PUT TRUCK IN NEUTRAL AND INCREASE RPM'S OR YOU 2 FEET ON THE BRAKE PEDAL ITHE POWER ASSIST WILL SOON RETURN, THESE SITUATION COULD BE A REAL PROBLEM AT HIGHER SPEEDS. I HAVE CHECKED THE VACUUM BOOSTER FOR LEAKS, BRAKE FLUIL AND DONE A FRONT AND REAR BRAKE JOB. THE WEEK OF NOV. 18 I SAW AN ARTICLE IN THE BOSTON GLOBE ABOUT THIS SPECIFIC PROBLEM AND UNDER INVESTIGATION. I CONTACTED MY LOCAL DEALER CENTRAL BUICK AND GMC IN NORWOOD MA..ON NOV 26.2018 THE SERVICE WRITER SAID HE KNEW NOTHING ABOUT THIS PROBLEM OR COMPLAINTS NOR THE ONGOING INVESTIGATIONS. HIS THOUGHT WAS BRING THE TRUCK IN AND WE WILL CHECK AND REPAIR AT MY EXPENSE. SADLY I WISH HIS RESPONSE WAS DIFFERENT . THANKYOU D.S.M.
Service brakes, Nov 27, 2018
AT SLOW SPEED BACKING UP OR MOVING FORWARD, I LOSE POWER ASSIST FOR BRAKING, HAVING TO ALMOST STAND ON THE BRAKES TO STOP. THIS HAPPENS INTERMITTENTLY. STREET OR PARKING LOT.
Service brakes, Nov 26, 2018
BRAKES BECOME VERY HARD TO PRESS IN TRAFFIC AND WHILE BACKING UP. THE CONDITION WORSENS WITH MULTIPLE PRESSES OF THE BRAKE PEDAL. THE STOPPING DISTANCE OF THE TRUCK IN INCREASED EVEN WITH INCREASED PRESSURE ON THE PEDAL. THE TRUCK HAS 28,463MI. I CONTACTED A DEALERSHIP AND THEY WILL NOT COVER THIS REPAIR. I HAVE ORDERED THE PARTS AND WILL PERFORM THE REPAIR MYSELF. GM HAS ISSUED A SERVICE BULLETIN ON THIS PIT5361B.
Service brakes, Nov 26, 2018
BRAKES APPEAR TO LOSE BOOST WHEN STOPPING. HAVE TO PRESS PEDDLE WITH BOTH FEET. THIS HAS HAPPENED ON THREE SEPARATE OCCASIONS.
Service brakes, Nov 26, 2018
AT SLOW SPEEDS FROM A STOP IF YOU LET OFF THE BREAK PEDAL AND IMMEDIATLY REAPPLY THERE SEEMS TO BE EXTREMELY HARD BREAKING. ALMOST IMPOSSIBLE TO STOP THE CAR.
Service brakes, Nov 26, 2018
ON SEVERAL OCCASIONS THE BRAKE PEDAL BECOMES DIFFICULT TO DEPRESS. RELEASING THE PEDAL AND DEPRESSING AGAIN CORRECTS THE PROBLEM. TODAY WHILE EXITING A PARKING SPACE AT LOW SPEED TO AVOID COLLIDIONG WITH ANN APPROACHING VEHICLE IT TOOK BOTH FEET TO DEPRESS PEDAL. I AM A 200 LB. MALE. I AM NOT SURE A SMALL FEMALE COULD HAVE CORRECTED THE FAILURE IN A TIMELY MANNER.

WHEN I PRESS ON THE BRAKES, IT FEELS AS THOUGH THE MASTER CYLINDER IS GONE AND IT IS THE MANUAL TYPE DRUM BRAKES THAT HAS AIR IN THE LINE. IT TAKES EVERYTHING I HAVE TO PRESS THEM AND PRAY IT STOPS!! THE VEHICLE IS ALWAYS IN MOTION WHEN DETECTING THIS PROBLEM AND SEEMS TO OCCUR MORE REPEATEDLY IF THE BRAKES ARE PUMP QUICKLY IN SUCCESSION BEFORE APPLYING BRAKES OR WHEN THE BRAKES ARE PRESSED FOR AN EXTENDED AMOUNT OF TIME THEN YOU RELEASE AND REPRESS IT WANT STOP. ANOTHER ISSUE IS MY LANE ID WARNING. WHEN TURNED ON AT THE BUTTON, IT JUST BEEPS AT ME AND SHOWS SERVICE LIGHT. WHEN I FIRST TOOK IT IN WITH THE PROBLEM, THE DEALERSHIP CALLED ME AND SAID ALL FIXED, BUT IT DID IT BEFORE I LEFT THE PARKING LOT. THEY HAD MY TRUCK ALL DAY FOR THE ISSUE, PUT ME OUT OF A VEHICLE AND THEN SAID THEY WOULD NEED FOR EXTENDED TIME TO REPAIR BUT DIDN'T KNOW THERE WAS PROBLEM. HOW DO YOU MAKE THAT DETERMINATION WHEN YOU TOLD ME ITS REPAIRED. I JUST TURNED IT OFF AND HAVEN'T USED IN 2 YEARS.

Service brakes, Nov 25, 2018
DURING LOW SPEED BRAKING MANEUVERS WHILE PARKING IN MY DRIVEWAY BRAKE PEDAL PRESSURE REQUIRED TO STOP BECAME VERY HARD. IT TOOK BOTH FEET ON THE PEDAL TO ACTUALLY STOP THE TRUCK. THIS WOULD HAPPEN DAILY WHILE BACKING IN TO MY DRIVEWAY. ALSO DURING NORMAL CITY STOP AND GO DRIVING IT WOULD ALSO REQUIRE GREAT EFFORT TO STOP THE TRUCK AND THE PEDAL WOULD BE VERY HARD TO PRESS.
Service brakes, Nov 25, 2018
COMPLETE BRAKE FAILURE WITH NO WARNINGS. DEALER DIAGNOSTIC REPORTS FROZEN VACUUM PUMP. THE CONDITION WAS ENCOUNTERED IN MOTION ON A COUNTY RD.
Service brakes, Nov 25, 2018
VEHICLE LOSES BRAKE PRESSURE WHILE MOVING AT SLOWER SPEEDS. ONCE COMING TO A STOP, THEN DOING SLOW SPEED STOPS AND STARTS THE PEDAL WILL BECOME HARD AND REQUIRES GREAT EFFORT TO BRING THE VEHICLE TO A COMPLETE STOP. ISSUE STARTED AT ABOUT 38,000 MILES JUST AFTER FACTORY 36,000 MILE WARRANTY. ISSUE PRESENTS ITSELF MORE OFTEN IN REVERSE WHILE BACKING IN, ESPECIALLY IF GRADE IS SLOPED. HAVE HAD MULTIPLE CLOSE CALLS IN PARKING LOT SETTINGS WHILE TRYING TO BACK IN TO A PARKING SPOT OR INCH FORWARD. A FRIEND HAD THIS SAME ISSUE WITH HIS 2016 CHEVROLET SILVERADO, WHICH ENDED UP BEING A $1,800 FIX THROUGH THE DEALERSHIP. HE WAS TOLD THAT IT WAS A VACUUM ISSUE WITH THE BRAKE PUMP AND THAT A RECALL WOULD PROBABLY BE ISSUED. I HAVE BEEN HOLDING OUT ON SERVICE IN HOPES OF THIS RECALL BEING ISSUED.

STOPPED TO TAKE A BREAK WHILE TRAVELING. AS WE WENT TO EXIT THE PARKING AREA AND STOP AT THE STOP SIGN, NO REAL BRAKING POWER. HAD TO PUT BOTH FEET ON THE PEDAL AND PRESS INTO IT TO COME TO A STOP. WE WERE TRAVELING AT ABOUT TWO MPH. NO WARNING THERE WAS A PROBLEM. ONE MINUTE WE HAD GOOD BRAKES, THE NEXT, NOT. LUCKILY THERE WAS NO TRAFFIC, AS WE WERE UNABLE TO STOP AT THE STOP SIGN AND FINALLY CAME TO A STOP IN THE RIGHT LANE IF THE ROAD. THE MECHANIC STATED THE REED IN THE VALVE OF THE PUMP CAME APART.

I FIRST NOTICED THE ISSUE ON THE MORNING OF SATURDAY, NOVEMBER 10TH AS I WAS BACKING INTO A PARKING SPOT. AS I WAS BACKING IN, I NOTICED ALL OF A SUDDEN THE BRAKE PEDAL WAS ON THE FLOOR AND I WAS ABOUT TO PLOW INTO A CURB AND THREW THE TRUCK IN PARK. I DIDN'T THINK ANYTHING OF IT. THE SECOND TIME IT HAPPENED WAS ONE DAY LATER AS MY FIANCE AND I HAD JUST COMPLETED A 200 MILE DRIVE HOME. I WAS PULLING INTO THE PARKING LOT AT OUR TOWNHOUSE COMPLEX AND AS I WAS PULLING FORWARD TO BACK INTO THE SPACE, I NOTICED I HAD NO BRAKING POWER WHATSOEVER. I HAD TO THROW THE TRUCK IN PARK TO KEEP IT FROM HITTING A NEIGHBORS VEHICLE. I OPENED THE HOOD WITH THE ENGINE RUNNING, AND NOTICED A TICKING NOISE I HADN'T HEARD BEFORE AND MY BRAKE PEDAL ONLY HAD ABOUT 1/4" OF TRAVEL LEFT. I COULD PULL THE PEDAL BACK TO WHERE IT IS SUPPOSED TO BE BUT IT WOULD JUST FALL BACK DOWN TO THE FLOOR. I WAS ABLE TO VERY SLOWLY AND CAREFULLY PARK THE TRUCK USING PARK AND THE PARKING BRAKE. WITH THE ENGINE STILL RUNNING AND THE VEHICLE IN PARK, I DEPRESSED WHAT WAS LEFT OF THE BRAKE PEDAL AND HELD IT TO THE FLOOR AND HEARD A MOANING NOISE COMING FROM THE AREA NEAR THE MASTER BRAKE CYLINDER AND COULD FEEL THE BRAKE PEDAL SHUDDERING UNDER MY FOOT. I FEEL UNSAFE DRIVING THIS VEHICLE AND I WAS GIVING NO WARNING OF THE BRAKE FAILURE. I AM HAVING THE VEHICLE TOWED TO SEWELL BUICK GMC IN DALLAS AND WILL UPDATE WHEN THEY FIND CAUSE. I WILL ALSO BE CALLING GM CUSTOMER SUPPORT AS I FEEL THIS IS A HUGE SAFETY HAZARD.

TRUCK LOOSES BRAKING ABILITY AT LOW SPEEDS SUCH AS TRAFFIC OR PARKING LOTS.
Service brakes, Nov 2, 2018
ISSUE WHEN BRAKING THAT CAUSES THE BRAKE PEDAL TO LOSE POWER AND CAUSES THE DRIVER TO DEPRESS THE PEDAL EXTREMELY HARD TO HAVE THE BRAKES ENGAGE. THE CAUSE APPEARS TO BE A FAULTY VACUUM PUMP THAT REQUIRES REPLACEMENT. THIS COULD BE POTENTIALLY A LARGE SAFETY ISSUE IF THE PUMP FAILS AND THE VEHICLE IS UNABLE TO BE STOPPED IN TIME TO AVOID A POSSIBLE COLLISION. THIS ISSUE HAS OCCURRED BOTH WHILE IN TRAFFIC ON A CITY STREET AND WHILE ATTEMPTING TO PARK THE VEHICLE.
Service brakes, Oct 29, 2018
THE VACUUM PUMP CONTROLLING THE BRAKES HAS FAILED. WHEN THE BRAKE IS PRESSED IN STOP/GO TRAFFIC, IT WILL FIRST STOP THE VEHICLE, BUT IF THE BRAKE IS RELEASED THEN PRESSED AGAIN, THE BRAKES WILL NOT WORK AND THE VEHICLE CONTINUES TO ROLL FORWARD. A MECHANICAL/ELECTRICAL NOISE CAN BE HEARD BEFORE THIS OCCURS. THIS IS MORE NOTICEABLE ON WET ROADS OR ROADS WITH A STEEP DECLINE.
Service brakes, Oct 26, 2018
AT LOW SPEEDS (PARKING SPEED, SCHOOL PICKUP LINES, CREEPING TRAFFIC SPEED) THE BRAKE PEDAL WILL LOSE ALL BOOST PRESSURE. THE BRAKE PEDAL BECOMES EXTREMELY STIFF AND INEFFECTIVE. THIS SITUATION OCCURRED ON A FEW OCCASIONS AND CAUSED GREAT ALARM WITH MYSELF AND MY WIFE. GREAT POTENTIAL EXISTS FOR AN ACCIDENT INVOLVING MACHINERY, ANIMALS OR HUMAN BEINGS. THE VEHICLE WAS TAKEN PROMPTLY TO THE LOCAL GMC DEALERSHIP FOR SERVICE WITH A COPY OF GM SERVICE BULLETINNO.: PIT5361B. THE DEALER KEPT THE VEHICLE FOR SEVERAL DAYS TO PERFORM AN EXISTING SAFETY RECALL FOR STEERING ANOMALIES (RECALL # 18289) AS WELL AS DIAGNOSE AND REPAIR THE BRAKE BOOST ISSUE. SERVICE BULLETIN PIT5361B WAS FOLLOWED AND THE VACUUM PUMP ASSEMBLY WAS REPLACED TO RESOLVE THE BRAKE BOOST ISSUE. THIS REPAIR OCCURRED AT 40728 MILES - JUST BEYOND WARRANTY COVERAGE TERMS. TOTAL COST OF REPAIR $686.56. THE BRAKE BOOST ISSUE HAS NOT REOCCURRED TO DATE SINCE THE REPAIR. THIS VEHICLE IS NOT ABUSED OR INVOLVED IN ANY RIGOROUS ACTIVITY. IT IS A GENERAL USE VEHICLE AND IS USED PRIMARILY FOR FAMILY ERRANDS AND ROAD TRIPS.
