2014 GMC Sierra 1500 Problems

The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate. A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.

Fix: GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge.

If a wheel-speed sensor fails while the vehicle is going between 41 and 60 mph in four-wheel or automatic mode, the brake control software can wrongly apply the brake on one wheel. The vehicle may then pull sharply to one side without warning, which raises the risk of a crash.

Fix: The dealer will reprogram the brake control module (EBCM) at no cost to you.

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.

Fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge.

These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.

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. 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.

Fix: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced.

The electric power steering can briefly lose its assist, mostly when turning at low speed. If the assist returns after dropping out, the driver may briefly lose control of the steering wheel, which raises the risk of a crash.

Fix: A dealer will update the electric power steering module software at no cost to you.

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.

Fix: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced.

The seat belt tensioner cable can fatigue and separate when drivers slide over it while getting into the vehicle. If it separates, the belt may not hold the driver properly in a crash, raising the risk of injury.

Fix: The dealer will modify the vehicle so the tensioner cannot be damaged, and will replace any already-damaged tensioner free of charge.

3L engine or 5.3L engine. The overheated exhaust components may melt nearby plastic parts and may result in an engine fire.

Fix: General Motors will notify owners, and dealers will reprogram the engine control module, free of charge.
