| Description of the problem | Dear nhtsa, i own a 2006 toyota avalon xls, purchased used in summer 2009. A few days after ownership, i felt the car wanted to 'speed up on it's own', momentarily. I took it to our local toyota dealer (toyota of iowa city) who felt the problem might be due to 'gear shift set points' in the automatic transmission's computer programming. They reprogrammed the revolutions at which transmission would shift gears while driving. However, the surge problem persists. As time goes by and i read more about toyota's accelerator problems, i think this might be part of the same issue and so i would like to give you some detailed information on my observations. I have been studying it and made some careful observations about which conditions the surge occurs during, and would like to detail this for you. Perhaps under these conditions you might even be able to reproduce my surge situation in other toyotas. The problem occurs when the engine is warm. In order to ensure that the transmission shifting is not the issue, put the transmission manually into '3'. Drive on level road at about 30mph, the engine rpm's will typically be about 2000. Then, release foot from gas pedal. The engine rpm's will drop to about 1000, then spontaneously surge upward to about 1500 rpm. At that point, something seems to limit the rpm's from increasing further. This cannot be the correct operation; when one is not stepping on the gas pedal, the engine should slowly revert back to idle speed (or be governed by 'engine braking effects' if going downhill)... Correct? I think that in a situation where this spontaneous limitation of rpm surging might not occur, i could experience a 'wide-open-throttle' situation that everyone is talking about. Please contact me for more details, i think my car might hold some secrets to the mysteries of the toyota throttle issue. This could potentially save lives. *rm |
