Anonymous, NY (2012 Toyota Sienna LE 3.5-L V6)""the main motor for automatic sliding door driver side failed. There are two motors, one slides the door and the other makes sure it is latched. Just the slide motor failed. The repair cost is over a $1000, just the motor OEM is about $750. The alternator failed at about 120k mile which I think is not sufficient life. Again cost over $1000 for repair. Break job at 140k by dealer was never done properly but that is service quality and not the vehicle itself.""
Anonymous, TX (2012 Toyota Sienna XLE 3.5-L V6)""Again in Florida, we began to hear a rattle sound coming from the rear of the vehicle when accelerating from a stop. We brought it to a mobility specific repair shop because it is modified for a rear ramp to accommodate a wheelchair passenger. They thought it was a muffler issue and referred us to a localexpert who they use any time repairs are not connected to the modification .. By this time I still hadnt had the steering issue fixed at the dealer. Thought this expert could diagnose and fix both issues. He could not determine where the rear rattle was coming from. He thought one of the rear shocks looked badly worn so I authorized him to change them for about $550. It did nothing to eliminate the rear rattle. He did discover that part or the rear fender that was changed in the initial modification was loose. I returned to the mobility dealer and the repaired that for no additional charge. They had already charged me $280 for their initial inspection that didnt fix any of my problems. I was leaving to come home to Long Island at the end of March and decided since the dealer fixed the steering issue we would live with the rattle until we get home. BTW the so-called expert claimed to have run a muffler shop for 20 years and there was nothing wrong with the muffler. We made the almost 1300mile ride with the rattle on take off but no other issues. As soon as we arrived home I made an appointment with a local mechanic to see if they could diagnose and fix it. At the time do drop off one of the mechanics rode for a short distance to hear the rattle. He definitely heard it and explained he would need to investigate further. I anticipated leaving the car there for a few days. Its a very well respected place. Went home and about one hour later they called to tell its fixed and I could come down to pick it up. It was a muffler pipe problem that they need to weld something to fix. They charged about $240 and the car has been fine since. They did tell me that when and if the muffler needs replacing I should go to a specialty muffler shop because of the modifications in the original car design.""
