2005 Toyota Prius driver assistance problems

I started the car and the speed indicator didn't illuminate. I thought it was a lightbulb or something that that had gone out since the car drove like normal. When I got to my destination I tried to turn off the car but it didn't turn off. I called the campus car service, by the time they got to me (about 30 minutes) the car had turned off by itself. This has happened about 8 times since. There was a recall on this very issue where toyota admitted that high milage prius' were experiencing this problem. The recall ended in 2013. I just don't understand how a know issue is no longer being fixed when they clearly stated that it affects high mileage cars. So people like me who's cars haven't reached a 'high mileage" during their recall period are basically told to guess how fast the car is traveling?

The automatic braking system (ABS), vehicle stability control (vsc), brake light, and brake system warning lights (4) on the prius all came on and vehicle became very unstable while out of town. The owner's manual indicated that the dealership should be contacted and car should be taken in immediately for service. Since no dealership was available at the immediate location, the car was driven home (60 miles) in very unstable conditions. Upon bringing it to the dealership I was told it was a miracle nothing bad had happened because the "computer skid assembly" needed to be replaced at a cost of $1570.97 for just the part!!! I found it very interesting that the part was readily available as if I were replacing an oil or air filter. After confirming the cost with other dealerships, I consented to the work to be performed. Is this just another "built in obsolescence" feature? There appears to be nothing I could have done to properly maintain this new piece of technology and the sudden failure of the part posses a significant safety concern to consumers. In addition, how can any reasonable consumer be certain that this part failure was not input by the manufacturer into the car's control system. Makes me long for the days of manual vehicles and shade tree mechanics.

In 2007, we purchased a certified used toyota prius 2005 with 13,298 miles. We have owned this car ever since. We currently have about 81,000 miles on this vehicle. Brake failure incident on june 30, 2014, I was driving the 2005 prius slowly (10-15 MPH) along a roadway located in a tecumseh, mi city park: as the car approached a local street, I braked for a stop before making a right-hand turn. As I engaged the brake, the ABS system red light appeared, the red brake light was lit and the related buzzer was activated as well. As I braked, my right foot went all the way to the floor. I experienced complete and total brake failure. I finally stopped the car with the emergency brake. I drove the prius very slowly over the two miles home, using the emergency brake to stop as needed. My wife and daughter were riding with me in the car and witnessed the incident. On july 1, 2014, I contacted aaa and arranged to have the car towed to a repair shop in ann arbor, mi ' 30 miles away. After a week, at the repair shop I arranged to have the vehicle towed to the local toyota service facility. Over the previous five months, I experienced another curious problem that may be brake related. When braking on bumpy roads (we have horrible pot holes on many major streets and roads) or curb cuts, the car accelerates ever so briefly. The feeling of loss of control is very disturbing. It remains to be seen if this problem is related to the brake failure noted above. There were no injuries as a result of this brake failure. However, I had just returned home from business in a neighboring community 35 miles away. I often drive backcountry county roads with posted speeds of 55 MPH. If I had experienced the brake failure then, I might well have been killed along with others.

Traction control engaged on a hill with light snow cover completely stopping the wheels and preventing any forward motion, creating a dangerous situation. Pedestrians had to push the car up the hill while the accelerator was pressed to get to the top. Backing would have placed the car in a dangerous position with oncoming 50 MPH cross traffic . There should be an override for situations such as this to enable some forward motion to be maintained even if there is some wheel slippage. Occurred friday 14 feb 2014. This has occurred in the past on gravel driveways and other roads. This instance was by far the most troubling since pedestrians were involved.

The traction control override repeatedly engages arbitrarily under various circumstances, including hitting bumps/potholes at 35 MPH and accelerating from a stop on both wet and dry roads. I have seen reports online of people expressing their concern about this feature in snow, but our prius does it frequently. Aside from the inconvenience, this is a clear safety hazard when attempting to pull out into traffic. We have been told by the dealer that this feature cannot be disabled, but it would seem to me that it needs to be to avoid potential collisions.

I am the first owner of this 2005 prius and have kept up with all maintenance and recall issues. This is my first complaint. On a perfectly fine weather day, I was driving my usual route home coming to a line of stopped cars in the left turn lane on a relatively flat, unbumpy surface street and was about 1 car length from the stopped car in front of me when I applied my brake. To my astonishment, with the brake fully engaged, my car kept going forward as if I had no brakes and rear ended the car ahead of me. Luckily neither of us were hurt as I had already slowed down for the stop. There was no damage to my car (my license plate holder hit her bumper and caused a couple of paint chips on hers, which will probably cost me thousands of dollars to repair) but I can tell you I was thoroughly shaken up. No emergency lights or code lights went on inside the car. From reading other complaints on this site, I see this is not a new problem. I will be reporting this to my toyota dealer and to toyota.

We have noticed repeatedly (a dozen or more times) over three years of owning this car and 100k miles, that as we brake going over a bumpy section of road, the braking system fails and the car actually accelerates for one or two seconds. This is especially alarming when we need to brake suddenly in a curve on a bumpy road as it seems we will lose control of the car. I always brake with my right foot and my right foot remains off the accelerator and on the brake throughout these episodes. Our car is equipped with the vehicle stability system and the passenger notices that the stability system warning light comes on during these episodes. It is not simply that the car coasts when the braking fails, the engine actually sounds like it is revving up and the car noticeably speeds up. Once the bumpy section has been passed, normal braking resumes. This has nothing to do with the floor mat. This situation should be reproducible thru testing.

I first reported this to toyota march 10, 2010. I did so after talking with a coworker who had a 2010 prius. I have a 2005 prius. We both experienced the same thing. Therefore, I figured I should take it more serious. The toyota's safety incident number is [xxx] . When going over bumps and hitting the breaks I notice that instead of immediately slowing the car down, the car seems to either not slow at all and seems to accelerate. Knowing that going over bumps can cause a tire to temporarily loose contact with the road surface and that cars can electronically transfer drive from a tire that looses contact with the surface to the other wheel, there may be mixed signals happening. The brakes telling the car to stop, the traction control telling the acceleration to transfer. It seems the acceleration is taking precedence. Regardless, this seems that it could cause a problem if on a bumpy road surface or a pot hole or something and a car stops infront of me or a kid runs into the street or for some other reason I need to stop.

August 4, 2010 around 8:36pm I was on i4 heading eastbound about 13 miles from my house going around 66mph. The driving conditions were hot with no rain. When my emergency light, explanation mark light and the vsc light all came on at the same time and my car experience a jerking liking motion. I called my father immediately told him what's happening, he told me to turn around and get the car home. I turned around and as I was on my way home after exiting i4 on sand lake rd my brake light came on with a loud continuous beeping noise that lasted about 20 seconds every 2 minutes. When this loud beeping noise occurred the brakes would stop working for about 10 seconds than start again. I made it home at 8:52pm and parked the car in the garage.
