To:NHTSA. Webmaster@dot. Gov subject:Toyota Prius 2007 model comments: although my dealer has run a complete battery of computer tests, no explanation is apparent for the vehicle accelerating on its own at high speed on the highway. It has happened to me twice and it is terrifying. The two instances were a couple of months apart. Both times, I was on the highway and had driven 10-20 miles without a problem. Once the gas pedal was physically jolted up, the problem was corrected. When it is occurring, the brakes do not slow it down by more than 3-4 mph. My dealer is a-1 Toyota in new haven.

Experience: driving a 2001 Toyota Prius between 60 and 65 mph on I-494 in eagan minnesota. The sensor on the vehicle's accelerator pedal assembly failed I. E. The ability to get gas to the engine stopped. The car was towed to an authorized repair dealer and the part, which failed, was replaced. My complaint has two parts: (1) Toyota does not recognize a critical part like the sensor on the accelerator pedal assembly as a part of major significance. I believe it is major safety issue and must be corrected by Toyota. I was told by Toyota's customer assistance center the part was not defective and it failed because normal use. I am appalled to learn that a 6 year old car with 50,226 miles is equipped with accelerator unit which can fail when the average use is 8,371 miles per year. I am also amazed the customer service center is not interested in looking at this performance as a major defect. They told me they had no record of other incidents with this part. Yet when I talked to the Prius service team supervisor at two different dealerships, I was informed by each one they had replaced 4 to 5 of them. If my small survey revealed that number I can only guess what a nationwide survey would reveal. 2) in response to my asking Toyota to reimburse me for the $810. 41 bill their response was I should submit my request for reimbursement to my insurance company or to the firm which owns the car. Clearly, a situation of shifting the responsibility of making quality oem parts to a third party to absorb the cost and ignoring the major safety implications created when the accelerator stops functioning in a vehicle driven less than the average car.

2005 Toyota Prius, 10 months old, 14,000 miles. My wife experienced an unintended acceleration while coasting down interstate at 65 mph with feet off pedals.

2005 Toyota Prius with unintended acceleration. Consumer states that the vehicle accelerated without warning and caused him to hit the vehicle in front of him.

(1) normal driving, no abnormalities whatsoever (2) at freeway speed, in busy traffic, without warning: the car lost all motive power (neither gas nor electric working); the hybrid system warning icon displayed on the multi-function display. Luckily, in both instances, we were able to move to the shoulder while decelerating. After coming to a complete stop, we referred to the owner's manual which suggested turning the ignition key completely off and then attempting a restart. In both cases the car started up again and was drivable (although in the first case the warning icon remained displayed for approximately 10 miles). (3) took car to Toyota dealer who verified failure code(s) stored in onboard memory; dealer replaced accelerator pedal/position sensor assembly.

The contact stated when the warning lights came on the car stalled and eventually came to a complete stop. On September 6, 2005 the car slowed down to 37 mph. The warning lights came on and the car stopped. The dealer said it was the accelerator assembly, which was replaced at the consumers expense. On November 14, 2005 the coolant light came on and the vehicle would not accelerate, and then came to a complete stop. The dealer said it was the coolant sensor in the transaxle. The transaxle was replaced at the contact's expense. After picking up the car on November 23, 2005 the problem stopped. Prior to September 6, 2005 the onboard computer was replaced due to the aforementioned problem. The computer was replaced under warranty. Updated 12/2705.

Contact states while driving the vehicle stopped. The accelerator pedal was replaced.

I own a 2001 Toyota Prius. Several times in the last few months I have experienced a loss of power combined with my dash warning lights. I had one similar incident last year. The dealership claims their diagnostics find no problem (no codes = no problem). Therefore nothing is resolved and the car remains prone to loss of power, a dangerous condition when traveling on any freeway.

Car was being driven on multi-lane city arterial in moderate traffic. To try to quickly avoid an obstructing vehicle ahead, driver rapidly depressed accelerator pedal to fullest extent while steering. Car then immediately, and without warning, lost all engine power and rolled to a stop. Two general warning lights on dashboard illuminated. Repeatedly depressing accelerator pedal produced no motion or other result. After engaging emergency flashers, only way to regain engine power was to shut off ignition, which required engaging parking circuit and depressing power on/off button, then after shutdown procedure was complete, again pressing power on/off button and waiting for hybrid system to energize. Warning lights again came on but car now responded to accelerator and driver was able to move to parking lane. This was the third time in the eight months of owning this new car that such a sudden shutdown occurred. After the first two times in late November-early December 2004, car had been taken to dealer for service and was returned to owners reported as fixed by replacing faulty accelerator sensor.

2005 Toyota Prius -- floormat becomes lodged between pedals. -- while driving at high speeds (60-70 mph) on the freeway, I noticed a loss of sensitivity on both the brake and gas pedals. I had to press very hard to get a reaction from either pedal. As a result I was unable to keep driving at the same speed as the surrounding cars. Everything else seemed to be operating normally. The sensation continued for a few minutes until I could safely pull off of the freeway. Upon investigation, I realized that the floormat had come unhooked from its restraints and stuck between the pedals and the floor. I secured the floormat to its hooks once again and continued driving without trouble. This has happened a couple times since, but I recognize the symptoms and fix it promptly. However, I fear that another owner might experience this when they need to brake or accelerate suddenly to avoid an accident. (I noticed another posting that described the same problem). Perhaps Toyota should install locking hooks rather than the current ones that easily twist and unhook from the mats.
