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.
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.
General Motors LLC (GM) is recalling certain 2015 Chevrolet Silverado 1500, Tahoe and Suburban, GMC Sierra 1500 and Yukon, and Cadillac Escalade vehicles. Electric power steering (EPS) assist may be lost momentarily, followed by a sudden return of EPS assist.
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.

The vehicle developed a recurring cylinder #4 misfire with a flashing check-engine light, rough running, and reduced performance. Diagnostic code P0304 repeatedly returned. Replacing the #4 spark plug temporarily restored normal operation, but the misfire returned after a few hundred miles. The #4 plug was wet/oily, and fresh oil was found pooled in the #4 intake port while the other ports were dry. All eight spark plugs, ignition coils, and plug wires were replaced, along with the #4 fuel injector and both #4 valve-stem seals, but the misfire persisted. A valvetrain/lifter tick later became audible near 3,000 RPM. The failure has now been confirmed as a valvetrain failure that severely damaged/destroyed cylinder #4 and requires complete engine replacement. The vehicle is available for inspection upon request. This defect creates a serious risk of severe misfire, loss of engine performance, or complete engine failure while driving.

While traveling at highway speeds on Interstate 5 in Oregon, my 2015 GMC Yukon Denali experienced a sudden, catastrophic engine failure with zero advance warning. The vehicle instantly lost almost all propulsion and power while surrounded by high-speed traffic, creating an immediate and severe safety hazard on a major interstate. The engine began making a loud, severe knocking noise, and I was forced to navigate across lanes without adequate power to reach the shoulder. The vehicle was towed and inspected by Point S in Creswell, OR, where diagnostics confirmed a P0300 random/multiple cylinder misfire, with cylinder 4 specifically misfiring. Using a stethoscope and scanner to isolate the failure, technicians confirmed a catastrophic rod knock failure at the bottom end of the engine. The vehicle was then taken to Sam’s Automotive Service, where a complete engine replacement was executed at a total out-of-pocket cost of $16,000. General Motors has a well-documented history of internal engine failures on these 6.2L V8 platforms, yet they have failed to issue a safety recall for vehicles experiencing this sudden, dangerous highway power loss.

My 6 year old son and I were coming down the road and came up on 2 deer and I was coming up on a sharp curve and when I hit my brakes my steering wheel LOCKED up completely and the steering wheel is so bent where I tried my best to control it but I failed and we hit a tree head on. Broke my nose and my sons leg broke in between the back seat air bag and door air bag
The contact owns a 2015 GMC Yukon. The contact stated that while driving at 40 MPH, the rear brakes became inoperable, causing the steering wheel to seize, with no warning lights illuminated. Due to the failure, the vehicle crashed into a tree. The contact and the contact’s child sustained injuries and were transported to a local emergency room for medical treatment. The contact suffered a broken nose and a chest fracture. The contact’s child sustained a broken leg due to deployment of the passenger-side air bag. The contact stated that the air bags deployed during the crash; however, the driver’s air bag failed to deploy. A police report was filed. The vehicle was towed to the contact’s residence. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was not available.
There is a recall on my 2015 GMC Yukon, that I am not the original owner of. The recall is for the brake booster and says that it expired. I have had the car checked by two different shops (both confirmed it was this), and one of them was the local GMC dealership by my house. I called to make an appointment for the recall to be fixed, to which they said they needed to order parts and it would take a few weeks. I dropped the car off three weeks later per their request for then another person to call me and say they won't fix it because it is expired. It is a safety matter that the breaks don't work occasionally.
