4/5 Overall
NHTSA 5-Star Safety Rating
The 2023 Chevrolet Suburban has 3 recalls, the most serious being a pair of mechanical defects that can each cause a crash: engine failure in 6.2L V8 models and rear suspension bolts that can snap and knock the rear wheels out of alignment.
On the engine side, internal components including the connecting rod and crankshaft can fail, leading to sudden engine shutdown while driving. The suspension issue involves the rear outer control arm bolts, which can break under load, pulling a rear wheel out of its intended position and making the vehicle difficult to control. There is also a lighting software issue where the daytime running lights fail to shut off when the headlights are switched on, creating glare that can reduce visibility for oncoming drivers.
