I have the opposite problem of the folks with throttle lag on my 2007 RAV4. On a number of occasions when braking to a stop in close quarters, the engine revs to 4000 rpm and I am unable to hold the car with full brake pressure. When I shift to neutral to stop the car the engine revs to 6500 rpm. Same problems with dealer, "no computer record of malfunction, unable to duplicate problem, everything meets factory specs." No help from Toyota either. NHTSA site indicates Lexus drive by wire system had similar problems and they did nothing. I found the discussion of the computer reacting differently to different driving styles to be interesting as this has only happened once to my wife who is the principal driver of the car and happens frequently to me, five times in the past weekend. Quite dangerous as I nearly scared to death a pedestrian in a crosswalk. What do I have to get Toyota to replace the sensors in the system, assuming that will fix this? |

Replying to: applebee (Jan 29, 2008 9:31 am) I would forcefully suggest the dealer replace your accelerator pedal assembly and throttle body assembly. If you had an uncontrolled accelerator event which you could not control with application of the brake, that is pretty serious. You can't get the dealership to assume liability for the result of an accident. If the dealership won't work with you and replace these items at the least (and I'm assuming the problem could also be with the Engine Control Unit but am assuming it's more likely the pedal assembly or throttle body assemby at fault), then personally: I'd get out of the vehicle ASAP even if I had to take a loss. Your safety, the safety of others travelling with you, and the safety of others in the vicinity of your vehicle are more important than the financial loss.

Replying to: porschecarrera (Apr 09, 2008 9:40 am) and no i don't believe in passing a problem like that along to another person... i'd report it to the nhsta: http://www-odi.nhtsa.dot.gov/ivoq/ and to the manufacturer: http://www.toyota.com/help/contactus.html i wouldn't try to sell it private sale - i'd try to sell it back to a toyota dealership - the entity in the best position to replace some components to eliminate the behavior forcing me out of the vehicle. that's the best i could do. what would you propose for someone in that position? |

| This forum reads just like the Camry forum. The Camry is suffering from the same down shifting, jerking, cruise control problems, and slamming into gears. I also see another shared symptom in this forum, that is Toyota's arrogant refusal to fix the problem and the strategy of blaming the customer. It is abundantly apparent that Toyota will NOT help the poor souls who purchased their products. The only recourse is for owners to get tough and relentlessly apply the lemon laws that are available in every state in the Union. Money is all these companies understand and forcing them to buy back their junk beats hell out of begging for help they will not provide. | |

My RAV4 2007 actually kicks out of gear on deceleration/re-acceleration, for stoplights, tight turns and heavy stop and go traffic situations. It revs up to about 2000 rpm before it engages when I accelerate to proceed. This is a 1-3 second hesitation that I am told is normal for these vehicles...something about a bypass? Does anyone know about it? I was told originally, after the dealer re-set the computer, it was my driving causing the problem. They re-set it again and I had my husband, who drives entirely different from myself, drive it. Still it did the same thing. Finally the dealer had the manager, tech ride with me to see what was happening ( another tech actually took it home overnight). All gentlemen agreed there is a problem, but stated there are no bulletins or other complaints so they cannot do anything about it. I am now dealing with Toyota who said, as a complete surprise to me, that the dealer told them there is not a problem. I am very happy with most everything else about this vehicle. It is one of the best, most stable vehicles I have ever owned in snow, ice and slick conditions. It drives nicely and gets pretty good fuel mileage. But this transmission concerns me. Please respond with any information you might have concerning this condition. If it is 'normal', is there somewhere to look that explains the condition and what it is doing? If, as I have been told and believe, it is not normal, does anyone have experience or advice for me? Thank you

Replying to: goose602 (Dec 01, 2008 3:55 pm) wwest hesitation abolition dbw -dfg As of '08 Toyota has tried out a new fix, revised engine/transaxle ECU firmware that tries to determine the driver's "future" intent based on the rate at which the gas pedal is released. FAST, equaling/implying a coastdown intent and therefore the transaxle will more likely remain in the current gear ratio. Slow letup thereby implying an intent to enter cruise, constant speed mode, therefore an upshift if appropriate.
