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

Most recent owner complaints, unedited.
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.
Car was in motion, turning to park on slope parking area then gear fall out and rolling backward, therefore try to shift into parking gear, all gears didn't work, gear shift was not working at all then car rolled downhill to other side of curve. To prevent accident I got out to stop the car from rolling by holding on to the rear door handle, could'nt stop it, in the process I had injury to my left shoulder and back.
Traction control has randomly engaged 4 times in the past week, at speeds as low 35 MPH and on the highway at 65 MPH. Pavement was dry and we were driving straight, not turning. Braking is applied causing temporary loss of speed and pulling steering to one side for about 1-2 seconds. Control returns and trac control light continues to blink. Does not result in an error code.

Rack and pinion steering needs to be replaced. After researching this issue, found that this is a very common issue with this vehicle. Pretty scary to think I could be headed down the highway with my five children and potentially lose control of steering capability because of this faulty part.
