4/5 Overall
NHTSA 5-Star Safety Rating
The 2022 Chevrolet Suburban has 4 recalls, the most serious being two separate risks of sudden loss of vehicle control: engine failure in models with the 6.2L V8, and rear wheels that can lock up without warning in models with the 10-speed electronic transmission.
On the engine side, the 6.2L V8 has internal components that can fail, causing the engine to stop running while driving. The transmission concern is separate: a control valve in the 10-speed electronic transmission can fail and abruptly lock the rear wheels, which can trigger a skid or loss of directional control at any speed. There is also a seatbelt concern affecting the third-row seats: a rivet in the buckle assembly may not have been properly formed, which can allow the buckle to release or fail to hold during a crash, leaving third-row occupants without reliable restraint. Finally, the daytime running lights may stay on even after the headlights are switched on, creating a glare situation for oncoming drivers and reducing overall road visibility.
