Top problems in owners’ words

Air bags
84 reports4 crashes4 related recalls
“I was at a full stopped and rear Ended at 30 miles an hour and the air bags did not deploy and I am suffering many injuries pain and loss The air bags didn’t deploy at all”
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.”
Electrical system
27 reports2 fires
“Odometer Fraud. The contact purchased a 2012 Toyota Sienna. The contact discovered a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 48,230. It was later discovered that the mileage on the Title was 241,080.”
Power train
17 reports1 crash
“The contact owns a 2012 Toyota Sienna. The contact stated that the rear differential was making an abnormal whirling and grinding sound. There were no warning lights illuminated. The contact called the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to NHTSA. The approximate failure mileage was 79,000.”
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.”
