Structure

72 reports2 crashes1 fire1 related recall
“The automatic side doors of this Toyota sienna le have malfunctioned twice between expensive repairs. When the hardware comes off the guide rail, it hits the window behind the door and shatters in covering the interior and occupants with glass. I had the window repaired after I had the door hardware replaced after its first failure in spring of 2024. The door gave no indication it was failed until I noticed the window bulging and nearly broke again. The Toyota dealer didn’t seem very interested in covering the cost of the repairs I made in 2024 and can’t get me in until mid August which leaves me without transportation for a month.”

Steering

15 reports
“The battery light came on suddenly and the power steering went out making it extremely difficult to steer the vehicle. An accident was narrowly avoided. We replaced the battery, alternator, and serpentine belt. The problem resolved for over 6 months, then reappeared. It starts with no issue, is charging properly, the serpentine belt is intact. The power steering will come on and go off sporadically, the only warning being the battery indicator on the dash that comes on first. This creates a substantial hazard and risk as the steering is severely impacted with little warning.”

Wheels

12 reports
“On 8/22/2022 I had to replace the 2 front tires with MIM-Supreme Tour 18 inch tire 235/55R18. On 8/22/2022 I had 162,323 miles on the 2012 Toyota Sienna XLE 4 months later and 17,252 miles driven - the 2012 Toyota Sienna now has 179,575 miles and on 12/28/2023 the 2 front tires again have to be replaced - Matrix Toyr RS 11 on 18 inch rims. Now its July 2024 - again 6 months and now 6,700 miles and just the front tires are bald and dangerous to drive if any moisture on the road. All these tires are slated for 50,000 miles and I and not getting even half the mileage. Most driving is on highways and regular maintenance occurs on the car. this car should be designed to go at least 25,000 miles ( so once a year ) on a set of tires. I do not drive fast nor aggressive.”
