General Motors LLC (GM) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5.3L or 6.2L V8 engine. The output of the mechanical vacuum pump can decrease over time, decreasing the amount of vacuum/power brake assist.
A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.

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.

TAKATA RECALL : STILL WAITING ON A REPLACEMENT. NO ACTION TAKEN BY THE LOCAL DEALER.THE AIRBAG IS STILL INTACT, BUT THE VEHICLE IS STORED OUTSIDE IN THE SOUTHEAST TEXAS HEAT AND I AM CONCERNED ABOUT ITS FRAGILITY BECAUSE OF THIS. LAST CONTACT WITH THE DEALER WAS IN 2017
Service brakes, Feb 5, 2018
LEFT REAR BRAKE LINE APPEARS TO BE INSTALLED IN HARMS WAY. THAT IS, AN OBJECT ON THE ROAD COULD BE STRUCK WHICH COULD TEAR AWAY THE BRAKE LINE RESULTING IN LOSS OF BRAKING POWER. OTHER VEHICLES OF THE SAME TYPE ON THE DEALER'S LOT WERE OBSERVED TO BE OF THE SAME DESIGN. IF THIS BRAKE LINE IS LOST DUE TO ROAD HAZARD, WILL BRAKING POWER BE LOST? PLEASE ADVISE. THANKS.
Air bags, Feb 4, 2018, crash
STRUCK A DEER WITH THE VEHICLE AT APPROX. 75MPH. THE DRIVER SIDE AIRBAG DEPLOYED. CONTROL OF THE VEHICLE WAS MAINTAINED AND THERE WAS NO SUDDEN DECELERATION. THE COVER OF THE STEERING WHEEL, WHICH BEARS A PLASTIC GMC LOGO THAT IS HEAVIER THAN THE REST OF THE MATERIAL BLEW EXACTLY ON THE CORNER OF THE G. DUE TO THE LOCATION OF THE SPLIT THE LOGO HIT MY WRIST LIKE A HAMMER CAUSING NERVE DAMAGE AND PERMANENTLY STAMPING THE GMC LOGO ON MY WRIST. I CURRENTLY POSSESS ALL DEPLOYED SRS COMPONENTS ALONG WITH THE ACM THAT WAS IN THE VEHICLE AT THE TIME OF DEPLOYMENT. THE DAMAGE, ASIDE FROM THE SRS COMPONENTS, WAS ONLY TO THE BUMPER, GRILL, AND CONDENSER WITH MINOR DAMAGE TO THE CORE SUPPORT WHERE THE BUMPER MOUNTS (RADIATOR, FENDERS, AND HOOD WERE NOT IMPACTED). I QUESTION THE SAFETY OF THE WAY THE STEERING WHEEL SPLIT AS THE EDGE OF THE G HAS A SHARP EDGE THAT COULD HAVE POTENTIALLY SLIT MY WRIST OPEN. I ALSO QUESTION THE DEPLOYMENT OF THE BAG DUE TO NO SUDDEN DECELERATION AND THAT IF THE BAG HAD NOT BEEN DEPLOYED THERE WOULD HAVE BEEN NO INJURY IN THIS LOSS. ALSO I HAD PREVIOUSLY HAD AN ISSUE WHERE I STARTED THE VEHICLE ON THE FIRST COLD DAY, ALL WARNING LIGHTS ON DASH CAME ON AND ADVISED ME TO SERVICE ALL SYSTEMS. I TURNED OFF THE VEHICLE AND RESTARTED AND THERE WAS NO WARNINGS PRESENT. AFTER THE LOSS AND REPAIRS I EXPERIENCED THIS SAME ISSUE BUT IT WOULD NOT RESOLVE BY RESTARTING THE VEHICLE. THEY PULLED CODES AT THE DEALERSHIP AND PERFORMED A SOFTWARE UPDATE AND I HAVE NOT HAD THIS PROBLEM SINCE. IT WAS COLD DURING THE LOSS BUT THE VEHICLE HAD BEEN RUNNING SEVERAL HOURS AS I WAS DRIVING CROSS COUNTRY AT THE TIME.
Steering, Electronic stability control (ESC), Service brakes, Jan 25, 2018
WHEN DRIVING VEHICLE AT ANY SPEED IT STEERS TO THE LEFT OR RIGHT . NOT A SIMPLE ALIGNMENT PULL OR WANDER I CAN FEEL THE WHEEL AS TO WHICH WAY IT WANTS TO STEER AT RANDOM. IF NOT PAYING ATTENTION OR IF YOU WERE TO LET GO OF THE STEERING WHEEL IT WILL GO OFF THE ROAD ABSOLUTLY NOT SAFE TO DRIVE. WHILE ACCELERATING THE VEHICLE FEELS LIKE THE BRAKES ARE BEING APPLIED AND DOES NOT ACCELERATE I HAVE TO GIVE EXCESSIVE GAS PETAL THROTTLE TO GET UP TO SPEED. THERE HAVE BEEN TIMES I HAVE CAME HOME FROM AS SHORT DRIVE AND I CAN SMELL THE BRAKES THEY SMELL BURNT HOT. ONE INSTANCE I WAS MERGING ONTO THE HIGHWAY AND THE TRUCK STRUGGLED TO GET UP TO 60MPH I HAD THE PETAL FLOORED AND THE TRUCK WOULD NOT GO OVER 65MPH THE ENGINE WAS @ 5000RPM MAXED OUT IT WOULD NOT SHIFT NOR GO FASTER THAN 65MPH. RANDOMLY TRANSMISSION THUNKS THUD AND SLAMS INTO GEARS WHEN THE AUTOMATIC TRANSMISSION IS SHIFTING AT LOW SPEED BELOW 50. WHILE DRIVING TRUCK FEELS LIKE THE DRIVE TRAN IS BOUND UP LIKE BRAKE IS APPLIED ON INDIVIDUAL WHEEL(S) . I HAVE HAD NOTHING BUT PROBLEMS WITH THIS TRUCK VERY WEIRD ISSUES THAT DON'T MAKE MECHANICAL SENSE. ALSO THE INSTRUMENT CLUSTER GAUGES AND INFOTAINMENT SCREEN DON'T LIGHT UP JUST BLACK SCREENS AFTER STARTING VEHICLE. HAPPENED 2 TIMES NOW. RADIO WAS OFF WHILE DRIVING THEN CAME ON FULL VOLUME WITHOUT TOUCHING ANYTHING. SERVICE STABILITY /STEERING WARNING CAME ON ONCE.I CAN HEAR FRONT TRANSFER CASE ENGAGE AND DISENGAGE AT LOW SPEEDS RANDOMLY WHEN IN 2WD. RANDOMLY STUCK IN LOW GEAR WHEN ACCELERATING FROM A STOP. AND YOU DON'T HAVE TO USE THE BRAKES MUCH TO STOP YOU BECAUSE AS SOON AS YOU LET OFF GAS PETAL THE VEHICLE NEARLY COMES TO A STOP WITHOUT APPLYING BRAKES. AND IF YOU ARE TURNING IT WILL AT TIMES COME TO A COMPLETE STOP. HAS BEEN TO DEALER 6 TIMES NOW THEY SAY EVERYTHING CHECKS OUT. THERE IS A MAJOR COMPUTER ISSUE OR IS HACKED PER ALL IVE RESEARCHED.
