While driving at about 40mph on a city street I complete lost steering, brakes and vehicle control. I suddenly started severely swerving/ spinning. I suddenly had no control over the vehicle. The vehicle threw a bunch of codes at once including: anti-lock brakes malfunction, pre-collision system malfunction, secondary collision brake system malfunction, braking power low, parking brake malfunction. I tried to turn off and restart the car and it did not reset any codes. I have brand new tires on the vehicle and just had an oil change and check up two weeks ago. There was no reason for this to happen other than a complete and sudden safety failure of apparently multiple systems. Vehicle is cur

I had to replace the wiring harness and connectors on both sides, driver, and passenger And I had to pay out-of-pocket. The dealer said that this problem is common on 22 sienna's and I have seen other 22 sienna's with out their driver and passenger rear running lights burnt out.

For over a year now, I have been experiencing a random issue in my van with the brake system. It feels like a slippage when I hit the brakes to slow down and it will randomly feels like something slips and just give gives out and gets loose and like you are free falling until the brakes grab and actually stop. I have had it in the dealership twice to fix this issue. Last year they reprogrammed the brake actuator assembly control module, and it worked for a while, but then once again after several months, it started again and the second time I took it in they drove it around to try to get it to mimic the problem, but was not able to so Couldn’t do anything about it and just said to watch it a

Brakes release briefly when slowing to a stop. While slowing to a stop with steady pressure on the brake pedal, the braking action will momentarily give out, resulting in the vehicle lurching forward beyond the anticipated stopping/slowing distance before the braking action re-engages. This has resulted in near collisions with cars, bikes, and pedestrians as the vehicle suddenly stops slowing without warning and unexpectedly increases stopping distance. The problem is intermittent and difficult to reproduce, but has occurred repeatedly over at least 6 months of ownership. No warning lamps, error messages, or other related symptoms from the vehicle either before or after occurrences of the pr
