general problems of the 2012 Toyota Sienna

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.

My wife let me know that when turning to the right (not an aggressive turn, but a normal turn from one lane to the next), the whole electrical system of the minivan would shut down and then come back on. I had a mechanic check it out and they say that this is due to the electrical steering system and will have to be replaced by the dealer. He was able to reproduce the same condition where he was able to get the minivan to lose power when changing lanes. He strongly advised that we should have the vehicle towed to the dealer as he felt that it wasn't safe to drive due to this. I feel that this will end up causing a lot of crashes and also that this should be covered by the manufacturer under a recall.

C1433 error code has on my Toyota Sienna 2012 I think it is safety issue c1433 steering angle sensor internal circuit.

Every time I turn the steering wheel at low speed. . . It make noise sound like a lose bolt in the universal joint. . Toyota dealer could not find anything.

2012 Toyota Sienna developed a "clunk" in steering system while turning from a stopped position. The clunk can be felt through both the steering wheel and floor. This is caused by a well-known safety problem Toyota has had with several other models including rav4, highlander, and camry (some of which had recalls). Toyota is pushing the cost of their mistakes on its customers. This is an ongoing problem, along with others, with Toyota.

Steering knock is experienced at speeds of approximately 35mph and less whenever steering left or right. This condition was first noticed at approximately 80k miles and has gotten worse over the next 50k miles. The knock is not only felt in the steering wheel, but it has become an audible noise as well. I've read several complaints where dealers have fixed this known problem, however I haven't seen any recalls on this or any information from Toyota stating that this is a known condition and is safe to continue operation. Until Toyota acknowledges this as a known problem and determines whether or not it is a safety issue, then I'll continue to operate my 2012 Sienna with the understanding that it is safe to operate and just put up with the knock. It would certainly be great if Toyota would at least put its customer's mind at ease by at least making a statement about the condition and whether it is safe to continue operation of vehicles with this condition.

1) power sliding door opened while driving; 2) strer wheel always stay on right. I took my van to delaer (mark jacobson) and they have not fixed the sliding door after I report the problem with sliding door. After I started searching on internet and found that there is recall also. I called them there is a recall but they did not do anything. Recall date: November 22, 2016 dealer reference g04 NHTSA recall 16v858.

We have 54k miles on our van and heard a knocking noise when we would make a turn (right or left). I brought to dealership and they said we needed to replace the intermediate steering shaft. The cost was $750. I looked online and see previous recalls for Toyota for this same problem. I also searched and found several complaints about this same problem with newer year Siennas like mine. This is obviously a defect that is still impacting Toyota and consumers. Toyota was not willing to listen to our problem or help in any way.

The vehicle suddenly switched from parking position into reverse without engaging the brake pedal and rolled back. Before rolling back the vehicle was stationary in the parking position on the driveway of my house.
