Automatic Transmission Control Module Problems of Toyota Highlander

Electronic pedal position sensor does not respond to driver input in certain situations. The engine and transmission shift response becomes delayed for 2 or more seconds, and in certain driver situations poses a danger to the driver and other vehicles on the road. A shift and/or acceleration delay occurs when full rapid throttle response is required or needed in certain types of traffic scenarios such as entering freeways , negotiating traffic , changing lanes, stop and go and emergency type braking/acceleration maneuvers. The dealer and Toyota USA have been notified of this behavior, and no such fix has been announced. I have received many dealer/mfr. Opinions on this . The dealer just says that there is no information from Toyota on how to adjust or fix this common complaint. I am not alone on this. And complaints regarding driveability of vehicle has been well documented by owners of my2004-2007 Highlanders.

Recurring issue: while traveling at both highway and city street speeds, the driver attempted to pass by fully depressing the accelerator and the vehicle failed to accelerate for approximately 1-2 seconds. This has resulted in near-miss accident/injury incidents. The dealer was contacted and stated this was a routine complaint for this vehicle and the Lexus RX-330. The manufacturer, Toyota corporate, was contacted and the individual stated this was not a known issue. No mediation was provided from either contact. This issue seems to be related to existing odi id numbers: 10113278, 10114325, 10115243, 10120592, 10128880, 10129705, 10131894, 10132578, 10137651, 10145021.

My 2005 Highlander often hesitates right when I need the most acceleration.

2005 Toyota Highlander v6- the consumer drove off the lot on June 3, 2005; the cruise control behaved erratically and it often felt as if it was accelerating a couple of miles behind the desired speed. The consumer requested to pass this turkey which yielded different results. There is sometimes awkward down shifting and rapid acceleration which is preceded by hesitation. The consumer approached a village intersection, downhill with his foot on the brake. The consumer took his foot off of the brake and began to make a left turn onto desired street. The consumer tried to apply a bit of gas and nothing happened. The consumer tried to apply a bit more gas and again nothing happened. The third time the consumer added a bit more gas and the vehicle accelerated too fast causing the driver's and passenger's heads to tip back. This was a narrow main street in a main village. There were lots of possible targets, cars/ kids bikes, and others. Then there was the unanticipated down shifting for braking effect that tipped heads forward, but that was another story for another day, and not quite as annoying or nearly of the same concern. The dealer's service manager first asserted that there were no adjustments accessible for the mechanics. Inability to do something. After applying more gas and vehicle hesitation consumer searched for a technical service bulletin (TSB) and found none. But found one from June 3, 2005 that related to recalibrating of the transmission. Absolutely no mention of expressions of concern or earlier tsbs.

2004 Toyota Highlander hesitation in the transmission. Dealer said it was "normal", but I see complaints have been filed and the NHTSA is contemplating a formal investigation. My Highlander hesitates every time I remove my foot from the gas and quickly reapply it. In some conditions, it happens as I'm decelerating and press the gas. Also, periodically, the transmission will jump back and forth between gears as though the vehicle doesn't know which gear to be in.

My 2004 Toyota Highlander v6 (3. 3l with 5-speed transmission) has an intermittent fault where the automatic transmission will abrubtly drop down a gear (or gears) while simultaneously trying to accelerate creating a sensation like it is bucking or porpousing. Usuall stepping off of the accelerator is sufficient to eliminate the bucking sensation. This has occured since I purchased the vehicle new in August 2004.

Transmission hesitation and sudden downshifting create unpredictable and hazardous driving conditions on the streets (not highway).
