Traction Control System
My 2009 toyota prius, since i first purchased it april 2009, the anti-lock brakes seem to fail. When i brake and hit a bump in the road the anti-lock brakes engage and release the brakes. It feels as if i am sliding on ice. I discussed this with the toyota dealer last month, who dismissed this as normal anti-lock brake activity. I feel these cars need to be recalled and repaired. *tr

Traction Control System
When braking on the prius if you hit a pothole the car loses traction and skips ove the pothole. Loss of feeling for the control of the vehicle of a second or two. It happens every time when braking and hiting a pothole or manhole

I have a 2009 prius that is not a part of the "braking/traction" recall, however i've experienced the same exact problem from day one of driving the vehicle. On wet or uneven surface the traction control kicks in and car seems to lose power in the brake and accelerator for a few seconds and it is not possible to control the vehicle. In other words, you should be able to either brake and prevent a bad situation or…

2009 toyota prius: when driving over pot-holes, bumps, or uneven patches of road at all different speeds, the car's "traction light" will flash and the car will momentarily surge forward. It seems at this time that the brakes also temporarily lose power. This happens several times a week. This worries me as i feel this could lead to car accidents or put pedestrians in danger. Spoke with many other prius owners and…

Loss of engine power in 2009 toyota prius. When accelerating into traffic in wet or low traction conditions every time one of the front wheels looses traction, the engine abruptly goes to idle for 3 seconds and the car severely decelerates. Only by removing your foot completely from the gas pedal and reapplying throttle will the car start going again. This extreme over-reaction of the traction control system is very…

2009 toyota prius my 2009 exhibits similar braking issues to those being recalled on the 2010. At least weakly during slow braking over a bump, pothole, or damp surface, the "slip" indicator comes on and the car lurches forward for approximately one second. *tr

On a daily basis, my 2009 toyota prius loses control, skids, (the traction light goes on), fishtails and has brake failures on ice and snow. When i hit potholes or big bumps, the car accelerates and i have to quickly brake. The northbrook toyota service manager drove it today. The car lost control, skidded, the traction light went on, it fishtailed, and the brakes failed on the ice and snow. His comment was "that's…

It is a recurring incident/problem with my 2009 toyota prius. Braking at the same time one is going over a bump in the road or during intermittent slippery conditions. When braking at the same time the car is going over a moderately abrupt bump or parkinglot driveway entrance the anti-lock braking engages but there appears to be delay - possibly in connection with the switching from the regenerative brake mechanism…

My 2009 toyota prius is exhibiting the same braking behavior as previously identified in the 2010 models. There is a manhole cover on a street i frequently drive near a stop light. On numerous occasions when i apply the brakes to stop i have hit the manhole cover and at which point the car seems to loose control. While most days this is not an issue because there is no one in front of me, on occasion i have come…

2009 toyota prius vehicle slid into intersection, no collision occurred. Approx 3 ft past stop point. During moderate to hard braking, if a wheel hits sand or a pothole, the "traction control" system engages, causing the brakes to release for approx .25 to .75 second. It is very unnerving (to say the least) to be out of control of my vehicle. It is also repeatable when accelerating on a short entrance ramp around a…

2009 toyota prius. Strange behavior of antilock brakes/traction control system when hitting a single pothole or small patch of ice on otherwise clear road surface. Vehicle significantly dampens brake response and does not recognize that the tires are now on a good contact surface and continues to be in tc mode for excessive time period. Only way to assure you will stop within reasonable distance is to lift up on…

In addition to the traction control, abs, gas pedal/floor mat problems with the toyota prius there is also a safety issue with the power button. In an emergency situation, like the door coming open, throttle getting stuck, etc. You can't power off the vehicle quickly. You must hold the power button for some amount of time before the car will shut off. Unlike the toyota camry example where they suggested turning off…

I live on a dirt road 2 miles long with 1 mile uphill. I bought my new 2009 prius on march 10th 2009 and on march 12th could not drive out. Going up the hill when ever the drive wheel slipped the traction control would brake the wheel until, with many brief braking, the prius came to a stop. I was unable to go forward and had to back down the hill till i could find a place to turn around. This created a very…

Applying light to moderate pressure on the braking pedal of my 2009 prius while simultaneously going over a pothole at low to moderate speed (such as in traffic) causes the braking system to release and the car will fail to stop. Removing pressure from the pedal and reapplying pressure to the brake pedal usually regains braking function but causes a few seconds of lost braking. This is easily repeatable and…
