Toyota Sienna Minivans Investigated
The National Highway Traffic Safety Administration is investigating 2004 and 2005 Toyota Sienna minivans for potential problems with their power liftgates. There have been 14 reports of the liftgates unexpectedly closing. A total of 142,418 Siennas are included in the investigation. This doesn’t appear to have anything to do with user error; the investigation is focusing on a faulty seal that could cause the high-pressure struts that raise the liftgate to leak, causing it to close unintentionally.
Toyota is cooperating with NHTSA and says it is performing its own investigation of the problem. Because there is no recall associated with the investigation at this point, Sienna owners who haven’t experienced a problem must wait until the investigation concludes before having their vehicle serviced.
