While driving in town at about 25 mph, the car will accelerate by itself to 30mph, even if the accelerator is released. Pushing down on the accelerator has no effect. The acceleration is brief and stops by itself. This has happened several times over the last few weeks. Cruise control not engaged. The car computer was re-flashed at the dealer year to address to address sensitive accelerator issues.

S10 appropriate handling re Toyota vehicle sudden acceleration problem, owner of a 2006 Toyota Avalon experienced acceleration problem. Immediately after purchasing the vehicle, the consumer noticed a problem in accelerating, decelerating and shifting gears in the transmission. Since the vehicle was still under warranty, he took the vehicle back to the dealer a few weeks later. The dealer informed the consumer there was no major problem and that a minor adjustment was made to the shifting points in the transmission. The vehicle functioned fine for a while, but then the same problems quickly resurfaced. A Toyota representative stated the problem was not a defect; rather it was the way the vehicle was intended to handle due to its drive-by-wire system. The representative went on to say the drive-by-wire system did not have a traditional rod that connected the pedal to the engine; rather, the pedal went to an electronic system that sensed the intended acceleration and causes the engine to accelerate as directed by the driver. The consumer was told the hesitation he complained of was normal as the system was determining how much to accelerate. The consumer did not believe the sudden acceleration was due to a sticking pedal; rather a problem within the electronic transmission control module, throttle or onboard computer.

2006 Avalon engine surged. Sent E-mail to Toyota at that time. As I recall Toyota response by E-mail was "we are not aware of any similar incidents" I still have a copy of the E-mail I sent.

2006 Toyota Avalon gas pedal does not provide power until depressed over 50 percent travel then it suddenly provides power representative of half throttle. The check engine light flashes on and off when it does deliver power under this condition. On rare occasions when moving from stopped position the car accelerator is overly sensitive and acts like I just stomped onthe gas pedal and not the slow movement I gave te gas pedal to make a slow movement of the car. I have gotten used to the way it drives and it has been this way for the past 10 months. Today the gas pedal has very little response to throttle response. I cannot drive it this way and having car towed to dealer for service. Some days after driving over 30 minutes the car acts normally with exception of check engine light illuminated.

Since owning a 2006 Toyota Avalon I have complained about this car surging & taking off. Floor matts are not a issue since the were removed on the drivers side last year.. Toyota tells me that they could not find a problem. This has happened several times, not just one time.

I was traveling on the NY I-87 in my 2006 Toyota Avalon for approximately 30 minutes when the "check engine" light illuminated. Within a minute or so, the "check oil" light started blinking slowly at first, then after about 30 seconds it was on continuously. By this time I had pulled off into a gas station. As I was pulling into the station the engine was making a loud clicking noise. After it was parked, I checked the dipstick and there was no oil remaining in the engine. The underside of the car, including inside of wheels and brakes was completely coated with oil as well as the back of the trunk. Presumably from the spray underneath while traveling @ 65-70mph. I then purchased 3 quarts of oil, put it in the engine and it drained onto the ground. The mechanic stated there is a pin hole in the rubber section of the oil line. The use of a rubber hose for a pressurized flammable liquid system in this location is absolutely reckless. At a minimum, it should be some sort of armored or shielded hose. I'm amazed the car didn't start on fire from being doused with five quarts of oil leaking from the ruptured hose. The service person at the dealership indicated this is a common problem with 2006 Avalons and he couldn't understand why there hasn't been a recall issued. The engine repairs caused by this defect will cost me up to $5000. Today I found at least a 1000 complaints regarding this same issue on carcomplaints.com and aboutautomobile.com. I would hate to see a death result in this issue caused by fire due to hot oil.

Ltr fm (fl) re the defective transmission in her 2006 Toyota Avalon. The vehicle was taken to the dealer over five times within in a six week period. The consumer stated the vehicle would hesitate and then surge forward when gently depressing the accelerator. The rear seat belt was defective and the front passenger air bag sensor didn't come on at the proper weight as described by the salesman.
