general problems of the 2010 Toyota Sienna

When entering a slight curve in the road at moderate in town speeds there is a clicking sound to the left of the steering wheel in the dash then the traction control sensor lightt goes on. While freeway driving, it has happened 3 times out of the blue and warning buzzers sounded vsc light and traction control light went on and the steering jerked. . . Engine lost power . . . Very scary. I had rack and pinion steerling assembly replaced at about 40,000. The problem started at about 110,000 miles. I had all the wheel sensors replaced at about 115,000. I took it into Toyota dealership they said they couldn't find a problem. Took it to 2 different mechanics . . . One changed the sensors. Company says it hasn't been a problem but on the internet there are lots of identical posts. Definitely a safety issue. I've had the car 11 years and always did scheduled maintenance. Please see what the issue is.

I was advised that I had to replace my steering rack because of multiple leaks. I have spoken with quite a few people including my Toyota service advisor and was advised that the Toyota steering racks frequently fail between 75k and 90k and have to be replaced. This happens immediately after the 75k warranty ends. Also, when I drive speeds between 50-70 mph, and level out the speed, my car picks up speed when I am not initiating the action.

Toyota Sienna 2010 minivan engine stalls while driving. When driving on highway or on city roads, engine stalls and looses engine power for a few seconds (seemingly happens when shifting gears) when accelerated or decelerated. The engine basically stalls during driving and may lead to sudden vehicle slowness in middle of traffic. The suspected problem advised by Toyota is with transmission and the original cost estimate was $5100 to fix that. Later after discussing with Toyota it was lowered to $3800 (approx) and Toyota warranty support was ready to pay (absorb) $2000 and $1800 to be paid by the customer. Even after initial repair and payment of ($1800+tax) $2166 the vehicle still have the same symptoms and issues. Presently the vehicle is under repair with the dealer (fremont Toyota, CA). The vehicle use was normal, regular city/highway usage, well maintained single owner. Nothing heavy was towed and used in rough or abnormal conditions. If possible ntsb needs 1.

2010 Toyota Sienna was stopped at a red light, with my right foot on the brake, when it suddenly launched itself into the back of the vehicle in front of me. (this was almost unbelievable, but thank god I had a witness! a gentleman previously unknown to me, who just happened to be standing on the side walk when he saw it happen. As I stepped out of my vehicle, I heard him describing to the driver in front of me what I had just experienced. ) updated 04/07/14. . Updated 04-29-14.

In the qfc parking lot, at around 5pm on a clear Monday evening I went to turn left into a parking spot. I stepped on the gas and nothing happened, I let up a bit and stepped again and my 2010 Toyota Sienna shot forward. I slammed on the brake halfway into the parking spot and ran into the tree in front of the van. I looked down and could see the outline of the gas pedal so my foot was definitely on the brake. I was very shaken up. The vans bumper and hood are damaged and the tree lost some bark. I had it towed to the Toyota dealership and Toyota is having it investigated. It has been there for a month now. Police were called, but did not take a report as there were no injuries.

The contact owns a 2010 Toyota Sienna. While driving at speeds of 10 mph, the vehicle abnormally accelerated without warrant and crashed.

When car is started even in warm weather, engine races and can get up to 30 miles per hour without depressing accelerator. Sometimes takes 15 to 20 minutes to get to a normal idle.

Involuntary acceleration. The failure happened within the first 30 miles that we had possession of the vehicle. There was only 430 miles on the vehicle. The vehicle is currently at Toyota body shop and we are awaiting disposition of the vehicle.

At vehicle start- cold ambient temps -approx 20f and lower, engine goes to about 1800 rpm and stays there for about 2 minutes before dropping down to about 1100 rpm. After shfiting and the driver taking the foot off the brake pedal the vehicle has a tendence to lurch due to the high engine speed. This is a surprise event every time I or my wife start this vehicle and I consider it a safety related issue. As a comparison, my 2003 chevy trailblazer cold engine rpm never goes above 900 rpm and does not exhibit this lurch tendency. I complained to the Toyota dealer service manager, and he offered no resolution- basically ". . . That's the way it is. " the dealer has no known procedure to adjust the cold start engine speed to a lower level. I have a documented service report.
