Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2008 Toyota Yaris Owner Comments

problem #17

  • 118,268 miles


I was less than five minutes from home, on my way to take my children to school. I made a right hand turn off the street from my neighborhood, unto the service road that leads to the ramp for the highway entrance. As I headed towards the ramp that enters unto the highway, the 2008 Toyota Yaris felt like it suddenly started to accelerate. Despite my foot was on the brakes, the car would not slow down. I swerved back unto the service road to avoid continuing unto the ramp, in fear that I would crash into the cars on the highway. To avoid hitting any vehicles on the service road, I managed to swerve the vehicle off the side of the road with the car finally stopping when it crashed into a pole. My children and I suffered seat belt bruising and cuts. I was hospitalized for a few days for hand, foot, and back injuries, and still under doctor's care for the injuries. In addition, the vehicle was a total lost. I have my service receipts reflecting that I kept up with the maintenance of the car. In addition, I had the brakes serviced in October of the previous year...updated 03/15/16.....updated 03/31/16

Our daughter was driving on highway 44 in Missouri at or near grey summit Missouri with the cruise control set on, when our 2008 Toyota Yaris started to accelerate on it's own. Our daughter had to swerve to miss hitting other vehicle on the highway. She attempted to stop and the cruise control did not disengage. To avoid hitting another vehicle she steered the vehicle off the highway and crashed head on into trees. Toyota hired Bosch to have the "black box" analyzed. The company and Bosch claim no malfunction of the vehicle. Our daughter continues to dispute their claims and we have lost the vehicle in an insurance claim to aaa of Missouri. In additional we have lost value in the vehicle, we are paying insurance accident penalties and lost $1000 in deductibles. We continue to dispute Toyota and Bosch's claim that there was nothing wrong with the vehicle. Since our accident there has been additional evidence of "tin whiskers" as potential cause of electronic failure. We believe we have been the unfortunate victims of Toyota negligence and need to request assistance in fighting this issue with Toyota.

When using the cruise control and going up a hill, ABS light and brake light comes on. Now it does it even without cruise control on. Those lights come on when you start the car. The brakes and fluids have all been check and there is no defaults with any of that.

Driving vehicle on city streets, and attempted to brake. Brake and ABS came on, and ABS system engaged. Road conditions were dry, weather was warm and sunny. ABS engagement made it difficult to come to complete stop, even though road conditions were dry. Since initial incident, ABS system comes on periodically while driving and while braking. Toyota has denied any responsibility for repairs, even though this is a known issue that numerous Yaris owners have experienced. Later models for the Yaris have had the ABS design fixed to prevent this issue from happening.

My brake light and ABS light come on and go off every few days, my anti lock brakes disable and some times it's hard to slow down. It's the sensor, it started in the winter.

My vehicle has intermittently exhibited a failure to accelerate once a day or once every other day for a couple of months. The check engine light would come on and the vehicle would not accelerate until the ignition is turned off and restarted. My mechanic told me the problem might be related to the throttle body which he replaced with no improvement in performance. He also told me that Toyota has issued a tsb related to the fault recorded in the engine computer. P0121 is one of the codes mentioned in the tsb which was also the code recoded in my engine computer, however the tsb does not mention the failure to accelerate. I took my vehicle to the local Toyota dealer for further diagnosis. They told me the engine wiring harness needed to be replaced as per the tsb and that the cost would not be covered by Toyota because the vehicle has over 58000 miles on it and it was no longer under warranty. I was shocked that Toyota would not cover this repair considering the potentially dangerous circumstance one could find themselves in when a vehicle cannot accelerate. To my dismay this repair cost me 1000 dollars and its hard to believe that a 2008 model vehicle would need to have the engine wiring harness replaced.

We drive a 2008 Yaris. Because we got it used and the previous driver drove so much, its 3 year/36,000 mile warranty no longer applied, but we got an extended power train warranty. This year, the engine wiring harness broke, and we found out that Toyota knew about the faulty harnesses. (the tsb on it mentions replacing it with an "improved" harness.) while Toyota describes this as not being a safety issue, we feel otherwise, as the symptom is an immediate loss of power and inability to accelerate, which could be dangerous on the highway. Needless to say, since this part is not being recalled, since in a dbw car, this is not part of the powertrain, and hence, we are not under warranty, Toyota required us to pay $1000 to fix this.

I was driving my Yaris and attempted to pass another vehicle on a 4-lane road. I pressed on the accelerator pedal as I entered the left lane and nothing happened. The pedal went halfway down, but the engine did not respond. As I quickly tried to decide what to do as a car in the left lane behind me came up fast, the engine responded unexpectedly and I surged forward. The next time I depressed the pedal, it responded normally at the top of its travel. However, it happened again about 3 weeks later when I was stopped at a red light. The light changed and I pressed on the accelerator. Again, no response. This happened on and off until last week when it started to become more common than the normal response. Since I didn't want to pay Toyota for an expensive fix only a few thousand miles after my warranty ran out, I resolved to get used to it. I adjusted my actions so I didn't expect an immediate response from the car until the pedal got part way down to the floor and, though I'm sure it affected my gas mileage, I could deal with it. Then yesterday, as I pulled into my garage, the pedal response suddenly went back to normal and I almost went through the back of the garage. I bought this car (and one for my wife as well) because of Toyota's reputation for reliability and its fuel economy. Now I don't know what to expect. I have read that Lexus owners have reported the same problem. This is annoying, reduces gas mileage, and could be very dangerous.
