AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

    visibility: power window devices and controls

    General Motors LLC (GM) is recalling certain model year 2006-2007 Buick Rainier, Chevrolet Trailblazer and GMC Envoy vehicles, and 2006 GMC Envoy XL and Chevrolet Trailblazer EXT vehicles. Fluid may enter into the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board, causing window switches to become inoperative.

    exterior lighting: headlights

    General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles.

  • NHTSA recall #05V455000October 5, 2005123,592 vehicles affected

    steering: hydraulic power assist: hose, piping, and connections

    Certain passenger vehicles may have been built with a power steering hose that is not to specification. Under extreme steering maneuvers, such as turning the steering wheel fully to the left or right while braking, the hose may fracture and leak fluid.

    If this were to occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could also result in loss of power brake assist and increased braking effort would be required. If the power steering fluid spray were to spray onto hot engine parts, an engine compartment fire could occur.

    Remedy

    Dealers will inspect the power steering hose(s) for two suspect date codes and replace them if required. The recall will begin on october 14, 2005. Owners may contact Chevrolet at 1-800-630-2438, Gmc at 1-866-996-9463, Buick at 1-866-608-8080, Cadillac at 1-866-982-2339, Isuzu at 1-800-255-6727, or Hummer at 1-800-732-5493.
