Steering, vehicle Speed Control, unknown Or Other
03/10/2024
My vehicle steering/control has frozen a few times in the past 18-24 mos. This happens for me in wet conditions at slow speeds while trying to turn, usually to the right. The car also seems to slow on its own and pull to the side at these times. This has also happened while reversing out of a parking spot. I do not recall seeing any lights engage but I am more focused on steering the car safely and exterior factors at these times so I haven't noticed the dashboard. It feels like the power steering fails, and I have no control. Thankfully, I have not been moving at high rates of speed, nor been in a position to go into the lane of on-coming traffic or had someone in a lane near me, and have been able to hold in position or manually turn as much as needed. Steering seems to return once the turn is complete. I have been fearful of hitting someone or being hit from behind each time. My mechanic has been unable to recreate the experience and was unable to suggest a direct answer. I...

Steering, power Train, service Brakes
06/01/2023
Bought the van used last year. Previous owner said mechanic could not diagnose the issue. On slight curves similar to on-ramps while accelerating the Vehicle stability control (VSC) will engage unexpectedly, sound an alarm and jerk the steering wheel. Some times to the point of pulling the vehicle out of its lane. Road speed is decreased dramatically as it feels as though the ABS is engaging. This has happened to me at least half a dozen times since June 2023. The condition will continue for maybe five or ten seconds until the wheel is straightened and speed reduced. Searching the Internet seems it's a fairly common problem. The fix might be to replace the steering rack or disable the VSC system. It's reported by those experiencing the issue get little to no help from the dealerships which strikes me as quite strange... From what I've read it seems to affect 2004-2009 Siennas

Power Train
09/13/2023
The bushing for the gear shift is broken causing the lever to disconnect from the cord preventing the vehicle from shifting gears. This caused the vehicle to become stuck in reverse. The car was stuck in reverse when attempting to shift to drive, nearly causing my wife to crash into another vehicle. There are multiple videos on YouTube demonstrating this problem, it is a known issue. The vehicle/component has not been manufactured. No warning lamps, messages or other symptoms.

Unknown Or Other, service Brakes

Vehicle traction control system will activate around a curve and break the vehicle while the traction control warning system activates. Breaking around a curve in a wet road situation can be very risky. Numerous other Toyota owners have filed similar complaints.

Electrical System, vehicle Speed Control, service Brakes

The vehicle stability control system randomly engages and activates the brakes without cause. This can happen on a gentle curve going under the speed limit. It is very scary and I am afraid it is going to cause an accident. Internet research shows many owners with this issue and no information on the cause or a fix
