Owners report messages like 'Reduced Power' or 'Service Stab System' appearing without warning, which can cause the engine to drop to almost no acceleration. This can happen in local traffic or on the interstate, creating a sudden loss of power.
Complaints describe coolant leaks, often from the radiator or hoses, leading to overheating and smoke. In one case, an owner noticed an antifreeze smell at only 53,500 miles, indicating potential cooling system failures.
Owners report issues with the ventilation system, such as abnormal odors or the defroster not blowing cold air, which can impair windshield clearing. These problems are linked to recalls for the defroster fan motor.
There are reports of hood louvers detaching while driving at highway speeds, which can become a road hazard. This is tied to a recall for the hood, but some owners say repairs were insufficient.

Owners of newer Silverados report engine shutdowns while driving, sometimes with messages like 'Return to Neutral' or 'Press Start'. Others describe diesel particulate filter issues requiring dealer service for excessive soot accumulation.
Complaints include sudden loss of power or the vehicle going into neutral unexpectedly, even at low speeds in parking lots. This can leave the driver unable to accelerate, posing a risk in traffic.
Reports describe severe loss of normal braking, where the brake pedal remains firm but braking is ineffective. Other electrical issues include the engine shutting off while driving, with screens going blank.
Owners report sudden braking loss, often accompanied by electrical warnings. In some cases, the vehicle shuts off entirely, and the driver must restart it to regain control.
