What owners report

  • Owners report airbags failing to deploy during crashes at highway speeds, sometimes with no deployment at all despite rollovers.
  • Cruise control and brake pedal issues are described where the vehicle would not slow down properly, leading to collisions.
  • Electrical wiring near the dashboard and driver door has caused smoke and flames, in some cases while the vehicle was parked.
  • Rear tires show severe inner-surface wear that owners link to a suspension alignment defect covered by a service bulletin.
  • Engine stalling has been reported after impacts, with the steering wheel locking and the car losing power on the road.
  • A key fob failure sometimes leaves the door unlockable electronically, requiring a manual override before smoke or fire was noticed.

2008 Chevrolet Impala recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 14V355000Jun 23, 2014Electrical System3,141,731 vehicles

    Electrical system:ignition

    This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.

    Risk: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.

    Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.

  2. NHTSA 12V377000Aug 3, 2012Suspension, Wheels & Tires36,413 vehicles

    Suspension:front:control arm:lower arm

    General Motors (GM) is recalling certain model year 2008-2012 Chevrolet Impala police vehicles because the front lower control arms may fracture. This safety recall does not include non-police Chevrolet Impala vehicles.

    Risk: A broken control arm can result in the loss of control of the vehicle, increasing the risk of a crash.

    Remedy: GM will notify owners, and dealers will replace both front lower control arms, free of charge. The safety recall began on August 21, 2012. Owners may contact the Chevrolet owner center at 1-866-694-6546.
