Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The left and right rear passenger doors failed to open due to breakage of the cable. I am uncertain of whether the child safety locks were engaged, however, the doors will not open wider than approx. 6 . Rear passengers had to crawl out of the van via the driver's or front passenger door. I am elated that the failure of the doors did not occur during a hazardous condition, since this would have placed the rear occupants in extreme danger. …”
NHTSA complaint #10434075, filed 2011-11, 72,000 miles“Vsc and engine check light came on. When I brought to dealer. They told me gas cap was not on tight. I thought that was an incorrect diagnosis since the cap was on and I had been filling my gas for more than 3 years. They reset the vsc light and gave me car back after charging me $98. Light came back on one week later.”
NHTSA complaint #10075432, filed 2004-06, 56,000 miles“2001 Sienna bought new from dealer. Driver side passenger power slide door had problems with 'switch' and ecu 8/2002, 11/2003, 1/2004, 7/2004, 7/2006 4/2007. Those are just the times I brought it in. Other times I just let it go for a while. Toyota fixed part until warranty was up. Now they want me to pay to replace the parts -- parts that continue to fail. Sliding door either does not open via power button, or will not close all the way. Safety issue when can not get door to close all the way. Now the other power slider door is also not working. …”
NHTSA complaint #10250566, filed 2008-12, 11,000 miles“Our 2001 Toyota Sienna has problem with the entire electrical system. The lights, interior and exterior, as well as all electrical outlets pulsate. They continuously fluxuate from dim to bright. There are even times when I have it on cruise and press on the brake that the radio goes off temporarily. Toyota has attempted to fix it but now they tell us that this is common with the siennas and avolans that have automatic climate control. They tell us that this is not a safety issue that I just need to drive it as is. We certainly disagree. …”
NHTSA complaint #10040904, filed 2003-09, 27,000 miles“Horn will not work in the rain or when you drive in water. It takes about a day for the horn to dry out for the horn to work at all. People could get killed when the horn will not work in the rain or water. Toyota needs to have a recall now to save the lives of millions of men, women and children in the USA.”
