general problems of the 2005 Toyota 4Runner

The secondary air injection pump is sending error messages and the vehicle is now in limp mode. The vehicle will not go over 30mph.

The contact owns a 2005 Toyota 4runner. The contact stated that while attempting to park, the vehicle abruptly accelerated and crashed into three unoccupied vehicles. The vehicle was not taken to the dealer for diagnostic testing. The contact did not sustain any injuries. A police report was filed. The manufacturer was not made aware of the failure. The contact mentioned that the vehicle was repaired under NHTSA campaign number: 06v253000 (speed control) several years ago. The failure mileage was 49,000. The VIN was not available.

On sat. Aug. 14, 2010 my 2005 Toyota 4runner accelerated backwards at a high rate of speed as I was attempting to back out of my sister's driveway. I had my foot on the brake at the time and tried to stop the car but could not. I put it in park, nothing happened, then I turned it off and we stopped. We actually backed into a grove of small trees and shrubs which caught us. The car was scratched up a little but not much damage was done. I did call the police and made a report. My younger sister was with me. The backwards acceleration was smooth and did not knock us around much and the stop was kind of smooth. After I turned it off I could not use the brakes anymore but at least we stopped. It was very frightening and I am afraid to drive the car any more. It is parked at my house. First I rented a car and now have borrowed one from a relative. I called corporate Toyota and an engineer from eaa is coming to brunswick Toyota tomorrow (08/26) to check out the car. Toyota offered no help with another car and say it will take up to 30 days to give me the results of the inspection tomorrow. Meanwhile I can't drive the car because I am afraid of it and I can't trade it in so I am stuck. The car was almost paid off and has never given me any trouble to speak of until this happened. I never suspected my car since I had not heard of any 4runners having a problem. I am an honest person and am well respected in my community. I wanted to do the right thing but it does not feel like Toyota wants to do the right thing. I feel that the least that Toyota could do is give me back the $25,000 that I paid for the car. Thank you for your time.

I am writing today to alert you to a potential accelerator problem with the 2005 Toyota 4runner SUV. In mid-December, my husband and I were driving on the highway when the car inexplicably accelerated, going from approximately 40 mph to about 60 mph within a matter of seconds. My husband, who has had professional driving instruction, put the car into neutral and was able to slow the car down, at which point the accelerator (which was moving towards the floor without a foot on it) popped back up and the brakes began working again. However, within this same journey, this same accelerator program occurred two additional times. We immediately took the SUV to Toyota of alexandria in virginia and explained what happened. They notified us that our car was not subject to a recall for accelerator problems but, based on our concerns, agreed to examine the SUV. To their credit, they did call in a corporate inspector to examine the dissembled drive train who in turn determined that an accumulation of oil in the differentials caused the cars computer to misread acceleration and deceleration information. Despite this diagnosis -- and subsequent replacement of the drive train and rear differentials -- Toyota mechanics were never able to replicate the acceleration problem that we experienced. After talking to several Toyota representatives, as well as a number of independent mechanics, we were advised to pursue arbitration with Toyota and are currently entrenched in that process. In the interim, we are using the car only for local journeys our of concern that this accelerator problem could reoccur. I am writing today to inform you of the problem so that you have a record that Toyota's accelerator problems may extend beyond the cars/suvs included in the recent recall.

I have a 2005 Toyota roadrunner. On three separate occasions, I had experience where the vehicle seemed to want to accelerate while I was 'braking' to a stop. On the 1st occurrence, I contacted Toyota and they told me it was a 'floor mat' issue. I know for sure it was not!!. The other two occurrences happened on the same day, floor mats were not even close to pedal and the pedal was not sticking. I put the vehicle into neutral to stop, and it gave me back control. I believe this is an ecm (engine control module) computer problem or sensor problem. I am a retired electrical engineer , my background is into computers and small microprocessors. I worked over 37 years in the steel industry on control systems using processors similar to those used in automobiles. I am awaiting the problem to happen again, and when it does I'm going to keep filing these complaints. Thank you.

Defect occurs during winter conditions only. While stopped & icy conditions exist, the vehicle has excessive hesitation when the gas pedal is depressed. The computer control allows the vehicle to move forward very slowly for at least 5 to 10 seconds after the pedal is depressed. When at a stop sign or light, this condition has lead to close calls while I have inched into the intersection. Not having the ability to accelerate to avoid oncoming vehicles has been problematic. The dealer noted the vehicle is working properly. The mechanics noted another customer had their vehicle in for the same issue & told him the same thing. Note that this condition has occurred each winter since I purchased the vehicle, but there appeared to be little that the dealer would "fix" since they did not believe there was a problem. I have assumed the root problem is with the computer control system, but I am not a mechanic.

Details: vehicle 2005 4 runner limited 4wd. The following occurs when coming to a stop, loud clunk sound and vehicle jolts forward right after a full stop. Infrequently the cluck and jolt will occur once stopped. This problem has been noted to occur after about twenty thousand miles. At about 3600 miles the Toyota was asked to diagnose the problem. Toyota stated they were unable to note any problems. It is ridiculous to assume that Toyota is unaware of the cause given the number of units on the road.

The contact previously owned a 2005 Toyota 4runner. The contact was driving approximately 5 mph on normal road conditions when the brakes were applied and the vehicle began to lunge forward, into the proceeding vehicle. The police was not notified. There were no injuries. The opposing vehicle sustained severe damages. The failure was intermittent during sudden braking occurrences. The contact was involved in three collisions as a result of the vehicle accelerating to include damages to the vehicle. The vehicle was damaged and repaired each time the crash occurred. The failure mileage was 5,000. The VIN was unknown. The contact no longer owns the vehicle.

While waiting at a stoplight, my foot lightly on the brake, the engine surges from a normal idle speed of 500 rpm up to 750-800rpm with no warning. This happens frequently but at random times. (remember the Audi 500) dealer has been unable to deal with the problem.
