The affected tires were cured for too long during production.
Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.
GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.

General Motors LLC (GM) is recalling certain 2020 Cadillac Escalade, Escalade ESV, Chevrolet Camaro, Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles. The fuel pump may be missing a pressure regulator, allowing for over-pressurization of the fuel system.
Over-pressurization can crack the fuel pump and cause leaks, increasing the risk of a fire in the presence of an ignition source.
GM will notify owners, and dealers will replace the fuel pump, free of charge. The recall began December 18, 2019. Owners may contact Cadillac customer service at 1-800-333-4223, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-888-988-7267. GM's number for this recall is N192283991.

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.

Power train, Service brakes, May 13, 2026
Tahoe transmission failed with 103,000 miles… took to Chevrolet they confirmed, took to a transmission specialist they confirmed failure but they said the computer was throwing weird codes and they believe this has a factor in transmission issue. On the way home the brake system alert went off and the car would not go above 35 miles an hour … I get this is a safety feature but it was dangerous in the location this occurred ans this car was not that old and does not have high miles to justify this type of issues

I own a 2020 Tahoe, 160,000 miles. While driving, the vehicle experienced a sudden loss of brake assist due to a failure of the vacuum brake pump. The brake pedal became extremely hard, and the vehicle would not slow or stop as expected, requiring me to put vehicle in neutral and frantically find a way to the shoulder to force a stop (pulling the emergency brake). This created a dangerous condition and significantly increased stopping distance, posing a serious safety risk to myself, and others on the road. There was little to no warning prior to the failure. This issue appears to be consistent with known complaints involving vacuum pump failure and loss of brake assist in similar vehicles. A failure of the braking assist system is NOT a normal wear condition and presents a critical safety hazard. I am reporting this incident due to the safety risk associated with sudden brake assist failure and the potential for accidents or injury. Vehicle issue has been confirmed by an independent service center. There was a warning light that appeared at the same time the brake stopped working leaving me no time to plan or know ahead not to drive.

While driving toward intersection, light changed to red. Applied pressure to brake pedal and pedal became extremely difficult to press. Vehicle was not slowing as expected with pedal pressure becoming very hard to press to slow vehicle. Warning on dash "Brake Assist" and Chevrolet app displays "Antilock Braking System" and text that states Schedule service now. If my wife would have been driving, this would have caused an accident. This is extremely dangerous condition that must be addressed with a corrective action taken by the manufacturer.

My 2020 Tahoe stabilitrak has gone off approximately 5 times over the past 2 months April and May of 2025 in one incident my vehicle did turn off all incidents were at low speeds less than 5 MPH. Four of the incidents the stabilitrak light turned on and an audible beep, I also lost power to my steering and breaks. When I had the oil change the service Tec at the dealer stated they can not test it unless the light WAS on? Has anyone reported or experiences this issues What can be done to fix this issue. Please email me at [XXX] if you have any questions or helpful hints. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

MY NEW 2020 TAHOE HAS AUTO/POWER PEDAL HEIGHT ADJUSTMENT. IT ALLOWS BOTH PEDALS IN UNISON TO BE LOWERED OR RAISED FOR COMFORT AND DEXTERITY OF USE. THE HEIGHT DISTANCE BETWEEN THE BRAKE AND GAS PEDAL IS EXTREME. THERE IS A INHERENT DANGER OF HITTING THE SIDE OF THE BRAKE PEDAL PRIOR TO GETTING ONES SHOE ONTO THE BRAKE PEDAL. WOMEN WEARING SANDALS OR OPEN FACE FOOTWEAR CAN POSSIBLY SNAG THEIR FOOTWEAR TO THE SIDE OF THE PEDAL PLATFORM. ANY HEAVY WORKING TYPE SHOE IS ALSO PRONE TO HITTING THE SIDE OF THE PEDAL FIRST. MY WIFE AND I BOTH NOTICED THIS DURING OUR SEPARATE TEST DRIVES. IN EACH CASE, THE TIMING OF ACTUALLY ENGAGING THE BRAKE PEDAL ENDANGERS THE DRIVERS ABILITY TO SLOW OR STOP HIS VEHICLE. ACCIDENTS WILL OCCUR. I ASKED THE SALESMAN IF THE PEDALS COULD BE SEPARATELY ADJUSTED, TO WHICH HE STATED IT WASN'T POSSIBLE.THE INABILITY TO ADJUST EITHER PEDALS HEIGHT INDEPENDENTLY FOR EACH DRIVERS DEXTERITY OF ENGAGEMENT IS IMPORTANT. WOULD BOTH AUTOMATIC POWERED SIDE VIEW MIRRORS BE EFFECTIVE IF THEY WERE SET TO BE ADJUSTED IN UNISON ONLY ? I'M NOT SURE WHEN AUTOMAKERS MADE THE DECISION TO NEGATE THE ABILITY TO ADJUST THE DISTANCE OF HEIGHT INDEPENDENTLY OF AT LEAST ONE OF THE PEDALS. THIS IS OUR FIRST VEHICLE PURCHASE SINCE OUR LAST IN 1985. IT APPEARS TO ME, THAT IT HAS BEEN AN UNAPPARENT OR UNNOTICED POSSIBLE REASON FOR ACCIDENTS. PLEASE LOOK INTO THIS MATTER. YOU MIGHT FIND MY OBSERVATION TO BE VERY LIKELY. *TR
