Toyota Power Window Fires and Excessive Lubrication: A Worldwide Epidemic

Question for the lads and lassies over at the Office of Defects Investigation: Are you going to penalize Toyota for waiting three years to recall a variety of models in the U.S. for power window switch fires, after it launched recalls for 770,540 substantially similar vehicles of the same model years in China, New Zealand and Japan in August and October of 2009?

The power window door fire issue got our attention February, when NHTSA opened Preliminary Evaluations into power window switch fires in the General Motors 2006-2007 Chevy Trailblazers and several 2007 Toyota models, including the Camry, the RAV4, the Highlander Hyrbrid and the Yaris. Consumers were reporting spontaneous burn incidents emanating from the power window switch area, starting –  but not always ending – with smoke and noxious odors. Few injuries; but many of the incidents happened while the vehicle was underway, and let’s face it, interior compartment fires are very distracting while driving.

It was NHTSA’s preliminary theory that perhaps the two automakers shared a common window switch supplier that would explain the defect trend.  And, both investigations proceeded together closely in parallel – like VPA1 and VPA2 circuits on the Accelerator Pedal Position Sensor in some early model Toyota Camrys. (Sorry, we can’t resist a little Unintended Acceleration humor.)  In mid-June, ODI bumped both PEs up to Engineering Analyses, and it turned out that GM and Toyota did not share suppliers.

GM was the first to concede the need for a recall. On August 17, GM recalled 249,260 2006 Chevrolet Trailblazer EXT and GMC Envoy XL, 2006-07 Chevrolet Trailblazer; GMC Envoy; Buick Rainer; SAAB 9-7x; and lsuzu Ascender s in a slew of states because fluid could seep into the door module, causing corrosion and a short that could render the power window or door locks inoperable, and in some cases, ignite.
