When braking while car is going over a pothole, car will briefly accelerate forward before stopping.

Sometimes after starting the car, brakes will only response to hard braking. Cannot brake to slow down gradually. Brakes will not respond at all when lightly pressing down on brake pedal. Only after driving about 1 mile will normal braking functionality return. This has been an issue ever since I first bought my car new.

Intermittently, several warning lights come on at once while driving: Traction control, brake, and ABS lights. While on, braking is lessened, brakes feel spongy, and the battery generation indicator shows no energy being produced. I found several similar complaints online. For me, the problem has comes and goes, affecting about 50 percent of my driving time.

I am entering this complaint based on reading dozens of accounts that resemble my issue exactly. Ten minutes into a forty minute drive three lights suddenly came on, the brake, ABS and traction control lights. The brakes immediately became soft, requiring 50-60% more effort to stop the car and drastically reduced stopping time. This occurred on a dark county road, after a light snowfall and temperatures in the mid-20's. I quickly pulled into a church parking lot to check the brake fluid level and for any broken brake lines. I also shut off the car hoping to clear the error, which it did not. Fluid levels looked normal and I decided to proceed the remaining 25 miles of my drive after ensuring that I could stop as needed. After 20 minutes of driving 45-55mph the lights turned off and braking power was instantly restored to 100%. I have not taken my car into the dealer yet, but plan on notifying them.

I had not any problem with breaks at all....once after taking a left turn.......check pcs sytem with other lights like warning, slippary, ABS, front breaks, came on. Emergency lights keep flashing even if you shut the car off. I took off the fuse 16 for turn signals...everything came normal....only that I dont have turn signals. As soon as I put the turn signal fuse back...emergency lights started flashing and check pcs system with all other lights came on. Dealer diagnosed the car for $ 150.00.....no clue....said they will charge me extra $550 to find problem.....on the second day evening they said I need to replace ABS actuator will cost me $ 4500.00

I was exiting exit 3 of interstate 91 in new haven ct and was trying slow down and stop but when I applied the brakes there was no response. I pumped the pedal several times but the brakes still failed. I steered the car to the left to avoid directly colliding with the vehicle in front of me and wound up scraping it and crashing into into a barrier. I have since learned that this has been an ongoing problem with the 2010 Prius and am outraged that the company has been willing to gamble with my safety and that of other Prius owners. I do not have the ability to scan documents but the claim number is allstate 0523873875 and the ct state police incident report is 1800537795.

I recently noticed that when I open the car door to get into the car (with the engine off), the brake assist primes for quite a bit (> 30 seconds). Then I start my car, I notice that the sound can be heard priming the brake (vacuum?) every 15 seconds or so and lasting about 3-5 seconds. It primes every time I release the brake pedal. The dealer said that the brake actuator is bad and will need to be replace or the car will not some in driving conditions.
