What owners reported alongside their complaints
Of 432 complaints: 21 mention a crash · 8 mention a fire · 16 report an injury · 22 say the car was towed.
17 complaints were filed in the last 12 months, the newest in Nov 2026.
Counts of what owners wrote in their complaints, not verified by anyone.
In owners' own words
Transmission failure during driving including humming noise and vibration, inconsistent shifting, difficulty shifting gears and hard/sudden shifting while driving.
My 2015 suburban has 103000 miles on it and the transmission failed. It is going to cost $5300 to repair. It is just over the powertrain warranty so this will be out of our pocket.
This vehicle has a push button start/stop. You can stop the vehicle while it is in gear, and if you get out the vehicle can just roll away.

Recalls for the 2015 Chevrolet Suburban: 11
A component missing from the drivetrain transfer case may cause the front and/or rear wheels to lock up without warning to the driver. Front or rear wheel lockup increases the risk of a crash.
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.
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.
Electric power steering (EPS) assist may be lost momentarily, followed by a sudden return of EPS assist. If EPS assist is lost and then suddenly returns, the driver may have difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash.
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.
In the affected vehicles, 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.
In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position. If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash.
Due to a problem with the EPS module, the affected vehicles may experience a sudden loss of power steering assist during vehicle operation. An unexpected loss of power steering increases the risk of a crash.
The affected vehicles were assembled with a roof rail air bags (RRAB) that were not reinforced at the points were the bags contact the hardware used to attach the roof carrier. During deployment, the RRAB may be punctured or torn by the roof carrier hardware, reducing its performance and increasing the risk of occupant injury in the event of a crash.
In the affected vehicles, an electrical signal short may cause the transfer case to shift to neutral without the driver's input. If the transfer case switches to neutral while the vehicle is parked and the parking brake is not in use, the vehicle may roll away increasing the risk of injury to bystanders.
The subject vehicles may have a transmission oil cooler line that is not securely seated in the fitting. If the line is not securely seated and transmission oil leaks from the fitting, the oil could contact a hot surface and cause a vehicle fire.
