general problems of the 2005 Toyota Avalon - part 2

We purchased a 2005 Avalon limited. From nearly the first day we noticed a hesitation driving. The symptom is that the car will hesitate as it thinks about what gear to go into. This is noticeable going up a hill, and is at its worst in a slow turn when the car seems like it might stall. Quite simply this is dangerous and from everything we have leered a result of drive by wire. The dealer says it is normal and there is nothing they can do. We spent close to $35,000 for this car and it is outrageous to have this problem. This car is dangerous to drive. There are numerous complaints about this problem on Avalon (as well as other Toyota models).

The consumer complained about an automatic transmission problem. When applying pressure to the accelerator pedal the gear would not engage. The vehicle did not shift gears smoothly. The consumer suspected that there was a problem with the vehicle speed control. The consumer lost control of the vehicle when another vehicle passed. The dealership informed the consumer that they could not do anything because the vehicle was computer controlled. (12/01/05).

Toyota Avalon 2005. Although I have not experienced a sudden power surge or runaway car, I do believe there is a link between the accelerator and the electronics. Ever since I have owned the car, brand new, in the twilight hours of driving, the dashboard panel lights will dim and go bright when I step on or let off the gas pedal. I reported this to Toyota when I first bought the car, but because it didn't react when the supervisor was in the car with me he couldn't report it or say what the problem was.

The contact owns a 2005 Toyota Avalon. When the contact depresses the brake pedal, the vehicle surges ahead or shifts to another gear. The dealer was unable to diagnose the cause of failure. He has spoken with the Avalon division of Toyota and they stated that someone will contact him in reference to the failure. The VIN and engine size were unknown. The current mileage is 22,500 and failure mileage was 20,000.

Since purchasing the Avalon in early June, I have been frustrated with how the car operates between 20 and 40 miles per hour. The car does not always know what gear it needs to shift into. It will frequently race 1000 rpm ahead without any change in speed. Then suddenly it will accelerate and the rpm's will drop back to normal rpm. It seems to happen most often in rush traffic when trying to change lanes. The hesitation in acceleration will cause me to lose most of my margin of safety in the process of changing lanes. In this regard, the car is not safe. There is no way to predict when the problem will occur, and therein, lies the safety hazard. It would seem that the last effort by the service department to update my computer programming failed to achieve any level of improvement to my satisfaction with one exception. Since the first computer upgrade, I have not experienced the complete loss of gear at high speeds. Is this a problem in all 2005 Avalons? is Toyota aware of the problem and do they have plans to resolve it? serviced on Friday, October 21. Toyota reset the computer learning back to factory default. Technical support in CA explained that there are no current plans to address the issue. Once the learning process develops a bad pattern, it must be reset back to factory default and the relearning started over. The problem started all over again and there is no "unlearning" the problem.

The contact had a 2005 Toyota Avalon. The contact stated that at the end of a long road , which he takes everyday, there is a tight spot were people slow down to make what is a very tight curve that then goes up hill. The contact tried slow down but the vehicle did not respond. The vehicle started to speed up as the contact tried to slow the vehicle. The vehicle was destroyed when the contact crashed into the large rocks on the side of the road. The contact was traveling at 55 mph. The failure mileage was 46000 miles at the failure and currently had 46000 miles.
