The shifter locks up in park and won't come out of gear. If the van is running or off it won't come out of gear. Having the parking brake on makes no difference. Have to rock the van back and forth to get it out of gear.

I've only had the van for 5 months and this problem has occurred over a dozen times, beginning with the day I bought it. And every time this problem has occurred I've been driving on dry roads. It usually happens when driving around a corner, anywhere from 35-65 MPH, far. All of a sudden the traction control light starts beeping, the brakes engage on their own, and then engine makes a loud noise (likely downshifting itself). It's as though the vehicle thinks it is slipping, even though it is not, I drive very cautiously so it's not me flying around a corner super fast, it also happens when my partner drives the van as well. I finally took the van to a mechanic and they told me it was the steering angle sensor that was faulty and needed to be replaced, so I spent $900 to have it replaced. I've had the van back for less then 2 weeks and just tried to take it on a road trip, got about an hour from our house and it did it again 3 times in less then 15 minutes, again driving on dry pavement and when driving on a windy highway. It's terrifying when this happens especially because it always happens when we're going around a corner, it's very dangerous and scary. It seems to be happening with a lot of other sienna's, even newer ones. This is an expensive problem that desperately needs to be addressed, someone is going to wreck and die from this if they haven't already.

The shift stick was loose and would move in any direction. If the car was driving on d and someone was to tap the stick shift slightly up or down, the stick would move even when the car was in motion and brakes were not pressed. Any major bumps would cause the shift to move loosely from its proper place as well.

My toyota sienna has 80,000 miles and has gear hunting, when I go on a speed bump it surges and hesitates, I don't feel safe at all. I've previously owned other toyota's with problems not like this. Please help. I love toyota, but I value safety.

The gear shifter is flopping back and forth and I'm afraid it will go into neutral and cause a huge accident or roll out of park and hurt someone.

Shift gear stuck in neutral mode for toyota sienna 2005. Driving sienna out of my garage in reverse, then stepped on brake--to proceed to move gear to drive mode. Then van got stuck in neutral mode. Attempted to move shift lever all the way back to p to get out of n mode, and nothing happened. Light stays on "n" position. Looked at vehicle manual to follow directions ie. If can't shift automatic transmission lever... Ignition key to lock, park brake on. Push down shift lock override button. Shift out of p position only while using a button. Shift to "n" position, start engine while keeping brake pedal depressed. Will have to have van towed to toyota dealer. This happened at home in the driveway outside of the garage. I was reversing out of the garage to drive out of the driveway to road.. I will need to contact toyota for an appointment first and hire a tow company to deliver to toyota dealer. Also, when engine is turned on and stepping on car brake, shift lever moves to p, r, n ,d, and lower gears but is permanently stuck in "n" mode is my best explanation. Fortunately, this incident occurred at home and not on the road, highway or other area of traffic. I can only assume some kind of cable/mechanism broke. Botton line, gear won't get out of neutral mode, even with steps as noted from vehicle manual.

The gear shift lever on our 2005 toyota sienna became loose and wobbly. The vehicle was in park and my wife shifted into reverse. She heard a noise like something had broken and fallen to the floor behind the gear shift lever. The lever was loose and wobbly after that. The dealer said there was no recall for our particular sienna.
