When slowly pulling into a parking space in front of a building, the vehicle suddenly accelerated across a 3-foot wide sidewalk and into one of the storefronts of a building--resulting in extensive damage to the front of the vehicle (currently in the body shop) and extensive damage to the storefront. Fortunately, no one was on the sidewalk at the time. This is the first sudden unintended acceleration for us...but apparently not the first for the 2009 Avalon.

The contact temporarily rented a 2009 Toyota Avalon. While driving 65 mph, the vehicle abnormally accelerated. The contact depressed the brakes and then shifted into neutral as he coasted off the roadway. The contact then shifted into park and shut off the engine. He was able to restart the vehicle as it resumed normal operation. The contact did not inform the rental facility of the failure. The VIN was not available. The approximate failure mileage was 25,000.

My 2009 Toyota Avalon has two recalls. Floor mat interference & sticky accelerator pedal. Toyota said I can have a redesigned accelerator pedal installed in April 2010. It's now 2.5 months later and IżM still waiting. Toyota has been installing the redesigned pedal on new cars coming off the manufacturing line for several months while not installing them on current customer cars. They keep holding me off. They prefer to saw my current pedal. I watched the dealer do this on a customer's car. A hand held hack saw is used to saw the pedal followed by a hand held metal grinder to smooth the cut. I paid $35,000 for a new car, not one hacked. I am filling this complaint for your records. Toyota still is not properly following through with this recall from Nov. 2009.

Traveling on interstate I began the procedures to correctly pass a vehicle in front of me. When I started to pass my Toyota Avalon accelerated before I could change lanes. I had a difficult time regaining control to prevent hitting the vehicle in front of me and to keep from hitting a concrete wall dividing the North/South lanes. I was bearing hard on the brake and I was able to regain control. I thought others on the interstate would be calling police about my irrational driving. This happened about two weeks before the problem was announced. I traded the car on February 4, 2010 because I did not feel confident driving the car.

I believe the Toyota acceleration issue has to do with the cruise control. I believe the cruise control is being invoked by a software bug and also the accelerate function of the cruise control somehow gets activated. I was driving a Toyota Avalon using the adaptive cruise control. I decided to bump up my speed to I tapped "accel" a few times. Before I knew it the car was at 85 mph on the cruise control display. I do not think I was actually traveling 85 mph, though. I hit the brake and it cancelled the cruise control and the car slowed down.

IżM the owner of a 2009 Avalon. Toyota's web page has a customer service phone number, 1-800-331-4331, for assistance with their recall for sticky pedal and floor mat entrapment. Iżve called twice. Each time I waited for 1.5 hours, then disconnected since they never answer but keep you on hold. This demonstrates that actions speak louder than words. Toyota is not serious about this recall. NHTSA need to insist that Toyota respond to phone calls regarding their recalled cars.

problem #6

  • 15,500 miles


When braking to a stop, just as the car finally comes to a stop, the engine revs kick up by a few hundred RPM. This is not on every occasion, but many of them ( 50% or more). Given the recent concerns raised regarding Toyota throttle control and brake software, I am becoming concerned.

My 2009 Toyota Avalon has two recalls. Floor mat interference & sticky accelerator pedal. I received a recall letter 4 months ago from Toyota but have never received a follow-up letter for repair. I have contacted Toyota several times by mail but they never responded. Toyota is installing brake override software on new Avalons, however is not available at my dealership for my car. My complaint is Toyota is installing the software on new cars but is not making it available for my car. That is a serious mishandling of safety. Toyota needs to be forced to take care of cars on the road before new production Avalons.

I was backing up into a driveway and the car started going real fast and when I tried to brake, it wouldn't stop and then my shoe got caught. I ran into a bld., I tried to miss it so I hit the corner of the bld. It was a very hard hit. It knocked me silly for a while. The car I was driving was a rental car which was a 2009 Toyota Avalon. I do not have the VIN # for this was a rental.

The contact owns a 2009 Toyota Avalon. During brake application the vehicle lurched forward. As a consequence she rear-ended the proceeding vehicle. The vehicle has not been taken to the dealership. The current and failure mileages were 18000. Updated 1/28/10 the consumer stated she was driving slowly and when she looked to her left a vehicle in front of her stopped to turn and they failed to signal. When she tried to stop, the vehicle accelerated. The consumer also stated the air bags did not deploy. Updated 02/03/10.

Going very slowly and heading into a curb in a parking lot, I stepped on the brake, and instead the car accelerated and stopped only when it hit a limb of a large bush. It left a dent in my front bumper. This has happened only one time.

After passing a car and speeding up from 90km per hour to 120 km I took my foot off the brake. The car continued on it's own, 120,130, 140 and topping out at 155km where at this time I had one foot on the brake and could only slow the car to 120, with both feet on the brake ( literally "standing" on the brakes) the car slowed from 120 to about 30 whereupon mu wife shut the car off. The tires were pouring smoke out of them and it took us about a mile to stop the car. It is a 2009 Toyota Avalon brand new. Have you had any other uncontrolled acceleration problems reported?
