This investigation was opened on Jun. 14, 2012.
It was closed on Feb. 12, 2013.
Note: this investigation has resulted in
a vehicle safety recall. On October 10, 2012, Toyota initiated a safety recall of approximately 2. 5 million u. S. Vehicles involving the following models and model years:2007-2009 camry and camry hybrid, 2009 corolla and corolla matrix, 2008 highlander and highlander hybrid, 2007-2009 rav4, 2008-2009 scion xb and xd, 2008-2009 sequoia, 2007-2008 tundra, 2007-2008 yaris, and 2009 pontiac vibe. See NHTSA recall number 12v-491 for more details, including the affected vehicle manufacture dates for each vehicle model. Note that only early-production 2009 model year vehicles are included in the recall. Toyota and gm dealers will inspect the power window master switch (pwms) assemblies and apply a specialized grease that inhibits heat build-up. The circuit board in the pwms may be replaced with a new one if "notchy" or sticking feeling is observed during the inspection. The failure report summary above shows counts for the vehicles identified at the start of this engineering analysis, specifically the approximately 1. 4 million vehicles that share an identical pwms assembly design including, model year 2007-2009 camry, camry hybrid, rav4, and yaris built from September 2006 through August 2008, as well as all 2008 highlander hybrid. Toyota subsequently identified approximately one million additional vehicles that have a slightly different pwms design but contain the same defect condition. Note that the totals for complaints and fires shown above may include duplicative reports (between odi and manufacturer reports). This engineering analysis is closed. See attached report for additional information. The odi reports cited above can be viewed at www-odi. NHTSA. Dot. Gov/complaints under the following identification numbers: 10323848, 10360414, 10392622, 10394453, 10411328, 10429983, 10436663, 10446699, 10447416, 10447417, 10447419, 10447444, 10447515, 10447845, 10447947, 10449270, 10450133, 10450568, 10450606, 10450641, 10451821, 10455540, 10455614, 10456353, 10456438, 10457854, 10457955, 10459730, 10460166, 10460691, 10461220, 10462140, 10462200, 10462247, 10462404, 10462705, 10462761, 10464451, 10464769, 10465421, 10466279, 10466667, 10468126, 10468265, 10475230, 10470313, 10470684, 10471551, 10471824, 10472336, 10472910, 10473753, 10473967, 10473969, 10476921, 10477469, 10478563 and 10478657. |
