Recently reported VEHICLE SPEED CONTROL problems on 2006 Toyota Prius

Unintended acceleration in my 2006 toyota prius. lasted less than 30 seconds. responded to repeated braking and hitting and pulling with my foot on the gas pedal. it happened when i floored the gas pedal to pass another vehicle.the pedal was not stuck to the floor mat. i could not reproduce the event after it occurred by flooring the gas pedal again. *cn

I have a 2007 prius and i have had a problem with acceleration 3 times. i read that it was thought to be a case of the gas pedal being caught on the floor mats. i took out the carpet mat and i currently have only the plastic all weather mat (i took out the carpet mat) which is secured with the two plastic hooks. my daughter gets her drivers license next monday and i was going to have her drive the prius. i'm afraid to have her drive it now. are you absolutely sure that the acceleration problem is just the floor mats and that there is no possibility that there is a problem with the electrical systems? because if it is just the mat issue then i have taken care of that. if it could be electric than i won't let her drive it. *tr

Toyota prius 2006. i pressed accelerator all the way down to accelerate and got stuck there. i was able to stop the car with the brake. it happens twice in july 2009. once i stopped the car i checked if the floor mats have done so. the floor mats were not the cause. the accelerator was stuck all the way down even with the engine off.... and only after a minute or two of the car stopped and engine off did came the accelerator back. i brought the car to the dealers and they told me that it was the mat. i told them that was not the case. the dealer put some grease in the accelerator and did a few more things (cleaning around and the fuel injection i think). since then i have avoided pressing the accelerator all the way down even when i need the power to accelerate at the entrance of highways and has not happened again. but there is definitely something wrong with either the mechanics of the accelerator or the electronics that somehow gets the accelerator stuck when you press all the way down. this should not happen and needs to be repaired. *tr

I have a 2006 prius. twice in 60,000 miles, when in cruise control, driving at highway speeds, and having to brake suddenly, the cruise control disengaged, as it should,. i brake, the car slows, as it should. then the car starts to surge up to the original cruise control set speed. i am able to brake and stop it, but at highway speeds, and approaching a near emergency stop situation- this has scared me. it has only happened twice...but memorable in the surprise it even happened. i reported it to a local toyota dealer, who couldn't recreate the problem, then also called the toyota corporation customer service, which said they had no reports of that happening. *tr

My 2006 toyota prius has several issues with acceleration, braking, turning car off and on alarm goes off constantly and terrible gas mileage around 30 miles per gallon. *tr

1. driving on the highway with the cruise control on. 2. we could not get the cruise control to disengage. neither tapping the brake or the cruise control switch would turn the cruise control off. we had to slam the brakes to disengage. 3. we turned the car off and restarted it. that fixed the problem, but we have not used the cruise control since. the toyota dealer could not find anything wrong. *tr

Tl*the contact owns a 2006 toyota prius. while stopped at a traffic light, the contact proceeded to accelerate and noticed that the engine engaged before the accelerator pedal was depressed. the contact was still depressing the brake pedal when the vehicle began to take off. he had to apply more pressure to the brakes in order to stop the vehicle. the vehicle was taken to the dealer, but they were unable to determine the cause of the failure. the failure could not be duplicated and no repairs were made. the contact is in the process of notifying the manufacturer. the failure mileage was 33,700 and current mileage was 33,720.

Tl*the contact owns a 2006 toyota prius. while driving at approximately 70 mph, the contact stated that the accelerator pedal went down to the floorboard when depressed. he engaged the brake pedal, turned the vehicle off and then restarted it which seemed to correct the problem. the contact stated that this failure was the second occurrence of the problem. he called the manufacturer and was told that they would get back with him when they were ready to repair the problem. the vin was unavailable. the failure mileage was unknown. the current mileage was approximately 104,000.

Tl*the contact owns a 2006 toyota prius. while driving approximately 50 mph, the vehicle accelerated when the brake pedal was depressed. the brake pedal required greater force to slow down the vehicle. in addition, the stopping distance was increased. there were no warnings and the failures occurred intermittently. the vehicle was taken to an authorized dealer for diagnostic testing, but they could not duplicate the failures. on three separate occasions, the vehicle was taken back to the authorized dealer for identical failures, but there were no resolutions. the manufacturer inspected the vehicle, but was unable to detect the failures. the failure mileage was 44,000 and current mileage was 49,000. updated 08/21/09. *lj updated 08/26/09.*jb

Back in 2009, i experienced runaway acceleration in my 2006 toyota prius. the cruise control had been engaged for between 5 and 15 minutes. all of a sudden, the vehicle started to race. i was traveling in the 70's (mph), and it shot up to nearly 100 before i got it under control. the dealer claimed he had no such other complaints and could not replicate my problem. i brought it back again a few months. later because the cruise control intermittently failed to set. i brought it back a third time, again, a few mos. later. this time, they had a fix, which was a new cruise control module. the first 2 trips were under warranty. they wanted to charge me the 3rd time because it was then beyond the 3 years of warranty. i fought this because the condition was obviously pre-existing. yesterday, steve wozniak received television and press attention when he reported the same problem, a problem that toyota told me they had never experienced before. as far as i am concerned, this company is scamming the public. they are playing with people's lives. it's got to stop. it's more than just brake pedals and carpet; it's apparently a way of life for this company. (i no longer have the vehicle. dates and mileage are approx.) *tr

Tl*the contact owns a 2006 toyota prius. while driving 60 mph, the vehicle began to accelerate on its owns and the speed increased to 90 mph. the contact depressed the brake pedal and the vehicle began to slow down, but failed to come to a complete stop. the contact was able to safely maneuver the vehicle to the shoulder and turned off the ignition. upon exiting the vehicle, the contact noticed that the brakes where smoking. the vehicle was towed to the dealer and they determined that the floormat was pinned down to the accelerator pedal when he applied the brakes. the brakes were completely destroyed and the vehicle was repaired at the cost of $1,600. the contact is in the process of notifying the manufacturer. the failure mileage was 73,000 and current mileage was 76,000. updated 04-14-09 *bf updated 04/15/09.*jb

While driving my prius i have experienced brief moments of unexplained acceleration. it was startling when it happened but was also over quickly. i believe it has happened twice. once was about one week after i had taken the car in for maintenance. i can remember thinking i might have to take the car in again. it felt like the acceleration when using cruise control, however, i don't and wasn't using cruise control. i have only the floor mats that came with the vehicle and do not believe this was caused by the floor mat. *tr

Tl* the contact owns a 2006 toyota prius. while the contact was driving 40 mph the vehicle had suddenly began to accelerate on its own. the contact was able to apply enough braking pressure to slow the vehicle, which allowed the contact to park the vehicle and shut it off. the vehicle was taken to the dealership where the contact was informed to remove the driver side floor mat. there were no prior warnings and the current mileages is 23000 and the failure mileage was 13153. updated 4/7/2010 *cn updated 05/06/10.*jb

Car accelerated without pressing on the gas pedal. had to apply the brakes so hard that they were left smoking to stop the car. towed it to mark miller toyota. they ran tests, and claim the gas pedal and brake were applied at the same time, implying that the problem was human caused. we disagree. have been driving for 30 years plus. no tickets in decades. the idea that we were applying the accelerator while braking hard is ludicrous. the computer registered that the pressure was applied to the pedal, but the computer applied the pressure. we also experienced this occurring on at least two other occasions. *tr

I came to a stop and the car actually came to a stop and then suddenly started creeping towards the other car. i thought i was accidentally pressing the gas pedal as well but i wasn't so i started pressing hard on the brake and nothing! i started pumping the brakes and the car stopped. then i continued my drive as usual without it happening again. no lights came on, nothing unusual. just weird. car has almost 36k miles 06 model. *jb

We have had several head lights on our pruis stop working. usually you have to turn the lights on and off to get them to go back on when they turn off on their own. we have replaced the headlights approx. 4 times over the years and again we are having the same problem. they are extremely expensive headlights. *tr the consumer stated she experienced sudden acceleration on three separate occasions.

I own a 2006 toyota pruis. i experienced two different times unintended acceleration. i can't tell exactly what was going on at the time. i hit the brake & shut off the cruise control. engine returned back to normal. i would guess it would pertain to some malfunction in the cruise. any other same complaints? *tr
