I approached the intersection of cortz rd. And 34 St. In bradenton, fl in heavy traffic. The traffic light changed from red to green, the line of traffic started to move forward. I applied accelerator and brake as needed with traffic, then the car in front of me stopped suddenly, I let up on the accelerator and pressed the brake and they did not respond as they should hitting the car in front of me. This all resulted in a 5 car chain reaction crash. It seemed as my car wanted to keep on going as if I had not done anything to stop. This is the second time I have had trouble with acceleration and brake control with this car in just over 30 days. The car is still in the repair shop. I do not have any confidence in this car to operate correctly or in safe manner. Toyota has done nothing for me to fix this problem. I have tried to contact Toyota by phone and computer without success. I have been to a Toyota dealer twice and they refer me to Toyota customer service phone no. Because the Sienna model is not part of the recall. However when I go to the NHTSA.dot.gov web site there are several cases listed of acceleration problems with the Sienna. Please help.

I own and drive a 2008 Toyota Sienna. I pulled out of car wash and drove over to a car vacuum center at less than 5mph. As I approached the vacuum area I touched the brake and the car accelerated fast, ran into a metal post, metal fence and over a curb almost hitting individuals in the area. This occurred in palmetto, Florida. This car seemed to have a mind of its own. There did not seam to be any reason for the acceleration at least not from my operation. I have to drive back to fort wayne, in and I'm concerned about the safety of this auto for me and my wife and all other on the highway.

I own a 2008 Sienna. There is an acceleration problem that I can replicate. It occurs when stopping at the bottom of an incline. Although Sienna is not on the recall list, it should be. It occurs often, the majority of times when going down a hill. My concern is that it will occur unexpectedly. No response from Toyota on this complaint.

This is a follow up to my 2/4/2010 report (ODI #10305864) about my 2008 Toyota Sienna. Ever since I bought it new in fall 2008, there is noticeable momentary unintended acceleration briefly whenever I press the brake pedal at speeds of about 30-40 mph. Then the brake takes hold. I had not given my VIN #. this time I will do that. (this is an ongoing problem that Toyota service says is normal, due to the nature of Sienna's transmission)

We drove from pembroke to North Carolina, taking a few breaks in between two weeks ago. We pulled into a service station to use the rest rooms and purchase cold drinks, in roanke springs, nc. My wife pulled into a handicapped parking spot in front of the store. She was only 10 feet from stopping the vehicle when the car accelerated forward and fortunately crashed into a concrete pillar otherwise we would have gone directly into the store. The surge of the car accelerating pushed me back into my seat, passenger. Our vehicle Toyota Sienna struck the concrete pillar directly in the middle of the front end. I then reached down and turned the car off. We were traveling with another couple, they had parked their car and heard the squeal of the brakes being applied and then the crash of our vehicle into the concrete pillar. The car is being repaired in roanke springs, nc at the bones Toyota dealer. We then rented a vehicle and continued our trip to Florida.

On Jan 29, 2010 my 11 yrs. Daughter and I were traveling in our 2008 Toyota Sienna South on hwy 51/I39. The roads and weather were basically dry. I had just set the cruise on 71mph when the vehicle surged ahead, the speedometer said 80, and within a minute had reduced to the 71mph I had set. It was very sudden and very scary to both of us. There was no foot on the accelerator and no floor mat was the problem. I feel this is a warning of what could happen and there are documented C/O since 2006 for Siennas that have this same problem.

Toyota Sienna 2008 model. Halted to make a turn in a parking lot, less than 5-10mph. Suddenly accelerated and hit another vehicle eventhough I was pressing hard on the brake pedal. Not mentioned in the recent vehicle recall by Toyota.

I accidentally hit the cruise control in my 2008 Toyota Sienna when the control lever was over the windshield wiper control in a slight left turn, resulting in the cruise control going unexpectedly into "resume". because of inclement weather I had slowed down and was not expecting the instant acceleration. Took a couple seconds to realize what had happened when I had tried to operate the windshield wiper control. The Toyota cruise control lever mounted on the steering column where it turns with the wheel appears to be a less than desirable engineering decision from a safety standpoint. Trying to express this concern to my local Toyota dealer, (pine bluff, Arkansas, where I bought the car) was unsuccessful. I had been trying to be helpful with Toyota's more generic problem of a complaint of uncontrollable acceleration, which Toyota has been trying to blame on improper floor mats being jammed into the accelerator pedal.
