I PURCHASED THE VEHICLE JUNE 2016 WITH 32K MILES ON THE ODOMETER. AUGUST 2016 AT 35K MILES WHILE DRIVING AT 55MPH, THE ENTIRE ELECTRICAL SYSTEM SHUT DOWN 4 TIMES WITHIN 2 MILES. AS I TURNED INTO MY DRIVEWAY, THE ELECTRICAL SYSTEM SHUT DOWN AGAIN ALONG WITH THE ABILITY TO CONTROL THE VEHICLE. THE STEERING WHEEL JERKED VIOLENTLY AND THE VEHICLE STOPPED JUST SHORT OF HITTING MY MAILBOX. ALL FUNCTIONS WERE DEAD AT THIS POINT. I TURNED THE KEY TO THE OFF POSITION AND BACK ON AND THE VEHICLE STARTED AS IF NOTHING HAPPENED. 3 DAYS LATER ON A FAMILY OUTING, AFTER PARKING THE VEHICLE IN A PARKING SPACE AT A THEME PARK, MY WIFE HAD FORGOTTEN HER THEME PARK MUG, SO WE WALKED BACK TO GET IT. WHEN I TRIED TO UNLOCK THE VEHICLE USING THE REMOTE KEY ENTRY, THE VEHICLE WOULD NOT UNLOCK. I USED THE KEY TO MANUALLY UNLOCK THE VEHICLE AND NOTICED THE COURTESY LIGHT WAS NOT ON WHEN I OPENED THE DOOR. I THEN TRIED TO START THE VEHICLE AND IT WOULD NOT DO ANYTHING. IT HAD NO POWER AS IF THE BATTERY WAS DEAD. AFTER SPENDING THE DAY IN THE THEME PARK WITH FRIENDS, WE WERE GOING TO GET A RIDE HOME DUE TO THE VEHICLE NOT STARTING. I TOLD THEM LETS TRY TO START IT AGAIN AND SEE IF IT WILL DO ANYTHING. IT STARTED AS IF NOTHING HAPPENED. I TOOK THE VEHICLE TO THE DEALER THE FOLLOWING DAY AND THEY SAID IT WAS A NEGATIVE BATTERY CABLE. THEY KEPT THE VEHICLE FOR A WEEK AND SAID THE PROBLEM HAD BEEN FIXED. 2 WEEKS LATER, THE VEHICLE STARTED THE SAME ERRATIC PROCESS. THE ELECTRICAL COMPONENTS SHUT DOWN AND THE STEERING WHEEL JERKED VIOLENTLY AT THE SAME TIME. THE SERVICE STABILITRAK LIGHT CAME ON AND THAT WAS WHILE DRIVING IN A PUBLIC PARKING LOT. IF THIS HAPPENS ON A HIGHWAY OR INTERSTATE, SOMEONE IS GOING TO GET SERIOUSLY OR FATALLY INJURED. I ALSO HAVE VIDEO OF THE ERRATIC BEHAVIOR. A PERSON HAS NO CONTROL OF A GM VEHICLE WITH THIS SAME ISSUE AND GM IS PLACING LIVES AT RISK.

I WAS HAVING WHAT I THOUGHT WAS AN ELECTRICAL PROBLEM. IN TRAFFIC AFTER HITTING MY BREAKS MANY TIMES I NOTICED MY DASH LIGHTS GO DIM, THE RADIO WOULD CUT OUT ONCE IN A WHILE AND MY GAUGE CLUSTER WOULD RESET JUST LIKE IT LOOKS WHEN YOU FIRST START THE TRUCK. THIS HAPPENED SEVERAL TIMES IN APPROX.30 MIN. I WAS PLANNING ON TAKING IT IN THE FIRST CHANCE I GOT BUT THE NEXT DAY I WAS DRIVING IN MY RESIDENTIAL NEIGHBORHOOD, A CAR WAS COMING THE OPPOSITE WAY WHEN AND I HIT MY BREAKS THE STEERING WHEEL VIOLENTLY JERKED OUT OF MY HAND AND CAUSED THE VEHICLE TO DRIVE UP ONTO THE SIDEWALK AND ALMOST INTO A RETAINING WALL. EVERYTHING WAS DINGING THE ABS AND OTHER LIGHTS WERE ON AND THE WORD STABILITAC WAS DISPLAYED ON THE CENTER DASH. THANKFULLY NO ONE WAS INJURED. I IMMEDIATELY CALLED THE DEALERSHIP WHEN I GOT HOME AND TOOK IT IN TO HAVE IT LOOKED AT. THE DEALERSHIP HAD MY TRUCK FOR SEVERAL DAYS AND OFFERED NO REAL EXPLANATION FOR WHAT CAUSED THE PROBLEM OTHER THAN IT WAS A SOFTWARE PROBLEM. NOW HERE WE ARE A MONTH LATER I'M DRIVING DOWN THE INTERSTATE AND TAKE MY EXIT FOR WORK. WHEN I HIT MY BREAKS THE LIGHTS GO DIM IN THE TRUCK, THE RADIO GOES OUT, THE ABS AND OTHER INDICATOR LIGHTS COME ON, THINGS ARE DINGING AND STABILITRAC IS DISPLAYED ON THE SCREEN ON THE DASH. WHEN I STARTED INTO MY TURN THE WHEEL JERKED VIOLENTLY MANY TIMES IN THE OPPOSITE DIRECTION OF MY TURN CAUSING THE VEHICLE TO GO ONTO THE SHOULDER OF THE OFF RAMP. IT TOOK EVERY BIT OF STRENGTH TO KEEP THE VEHICLE ON THE ROAD. I RELUCTANTLY CONTINUED ON TO WORK AS IT HAPPENED A FEW MORE TIMES. ONE OF THEM I WAS ABLE TO CAPTURE ON VIDEO. THE VEHICLE IS CURRENTLY AT THE SAME DEALERSHIP THAT MADE THE FIRST ASSESSMENT AND REPAIR. I DON'T FEEL SAFE OPERATING THIS VEHICLE EVEN AFTER THE REPAIR AS IT HAS BEEN PROVEN IT CAN AND WILL HAPPEN AGAIN.. SOMEONE IS GOING TO GET KILLED OR SERIOUSLY INJURED IF GM DOESN'T FIX IT.

AFTER HAVING THE BATTERY REPLACED, THE VEHICLE STARTED GIVING "STABILTRAK SERVICE REQUIRED" "REDUCED POWER TO STEERING" WARNINGS. AT THESE TIMES AND INTERMITTENTLY AFTERWARDS, THESE WOULD APPEAR AND THE STEERING WOULD THEN RESPOND AS IF THE ENGINE WERE NOT RUNNING WHILE UNDERWAY. THIS HAPPENED IN SEVERAL PARKING LOTS REQUIRING CLOSE MANEUVERING AS WELL AS ON THE FLORIDA TURNPIKE, ENDANGERING MY FAMILY, MYSELF AND OTHERS. THE LOCAL DEALERSHIP CLAIMED AND REPLACED THE ENTIRE POSITIVE ENGINE LEAD, STATING THAT WAS THE CAUSE. THE SAME ISSUE HAS ARISEN AGAIN AND NOW I AM BEING INFORMED THERE ARE NOW MULTIPLE LOW VOLTAGE CODES DUE TO THIS SHORT. RESEARCHING ONLINE FORUMS, THIS HAS BEEN AN ISSUE AMONG MANY WHO OWN THIS TRUCK. IT WOULD APPEAR THIS COULD BE A LIFE THREATENING SITUATION THAT NEEDS TO BE ADDRESSED. THIS BEGAN HAPPENING ON APPROX.

PROBLEM STARTED WITH THE RADIO DISPLAY BLINKING OFF WHEN I PRESSED BRAKE PEDAL OR ACTIVATED TURN SIGNALS. THOUGHT THIS WAS STRANGE, BUT DID NOT THINK OF IT AS A SAFETY CONCERN. I THEN GOT STUCK IN A LITTLE RUSH HOUR TRAFFIC ON THE HIGHWAY, I NOTICED WHILE HOLDING THE BRAKE ON FOR EXTENDED PERIODS OF TIME THE TRANSMISSION WOULD DOWN SHIFT EXTREMELY HARD AND JUST ACTING STRANGE ALL TOGETHER. TRAFFIC WAS MOVING APPROX 30 MPH WHEN THE RADIO BLINKED OFF THE DOORS LOCKED, UNLOCKED THEN LOCKED AGAIN. A MESSAGE FLASHED ON THE DASH SOMETHING STABILITRAK THEN STARTED SHIFTING EXTREMELY HARD AGAIN. I WAS ON THE INTERSTATE AND NO WHERE SAFELY TO PULL OVER. I WAS TRAVELING WITH MY [XXX] OLD CHILD AND HAD SOME SERIOUS SAFETY CONCERNS AT THIS POINT. NO MORE THAN A MILE LATER, WHILE IN THE SAME STOP AND GO TRAFFIC AND APPLY THE BRAKES, THE RADIO BLINKED OFF AND THE TRUCK SHUT DOWN COMPLETELY WHILE TRAVELING AROUND 30-35 MPH IN TRAFFIC WITH A TRACTOR TRAILER BEHIND ME. I WAS ABLE TO SHIFT THE TRUCK TO NEUTRAL TO START THE TRUCK AND CONTINUE TO THE NEXT EXIT. WHEN SLOWING DOWN THE TRUCK STARTED TO SPUTTER OUT ALMOST TO A STALL AND QUICKLY FLASHING A STABILITRAK MESSAGE AND THE DASH BLINKING OFF, UNTIL I RELEASED MY FOOT OFF THE BRAKE. I CALLED TO HAVE A FAMILY MEMBER COME PICK MY CHILD UP AS I HAD SERIOUS SAFETY CONCERNS OF MY CHILD BEING IN THE VEHICLE. I CONTINUED TO MY APPOINTMENT WHICH INVOLVED ACCESSING THE TURNPIKE THROUGH TOLL BOOTHS. WHILE SLOWING DOWN TO ENTER THE TOLL PLAZA THE TRUCK DID THE SAME THING RADIO BLINKED OFF, DASH DISPLAYS BLINKED OFF, SPUTTERING THE STEERING WHEEL AT THIS POINT RIPPED OUT OF MY HAND ALMOST CAUSING A COLLISION, STABILITRAK MESSAGE APPEARING. ONCE I GOT TO MY DESTINATION THE TRUCK SAT FOR APPROX 2 HOURS. MY RETURN TRIP WAS NORMAL AND DID NOT HAVE ANY ISSUES. THIS TRUCK IS A DEATH TRAP WITH THIS PROBLEM OCCURRING.

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.
Consequence & remedy
Consequence: A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.
Remedy: 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.

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
Consequence: 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.
Remedy: 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.

2EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

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.
