2017 Chevrolet Silverado 1500 Problems

The left-side or right-side roof rail air bag (RRAB) inflator end cap may detach from the inflator or the inflator sidewall may rupture. A detached end cap or inflator rupture can allow compressed gas to escape and project the end cap or fragments of the inflator into the vehicle, increasing the risk of injury.

Fix: Dealers will replace both RRAB modules, free of charge.

3-liter engine, a 3.08-ratio rear axle and four-wheel drive. 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.

Fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge.

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.

The owner's manual for the affected vehicles may be missing instructions on how to use the tether anchorage and child restraint anchorage systems. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 225, "Child Restraint Anchorage Systems." If the instructions are missing from the owner's manual, the child seat may be installed incorrectly and not be properly secured, increasing the risk of injury in a crash.

Fix: GM will notify owners, and dealers will provide a corrected insert for the owners manual, free of charge.

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 front upper control arms may have inadequate welds near the control arm bushing. Inadequate welds may allow the control arm to separate from the bushing, compromising steering and increasing the risk of a crash.

Fix: GM will notify owners, and dealers will replace the left and right front upper control arms and realign the vehicle, free of charge. Until the repairs have been made, owners are advised not to drive their vehicles.
