I took my car to a reputable mechanic and he told me it is giving him code c1391.…

When i go over a bump or pothole and put on the brakes the car accelerates. Toyota claims it is just how the abs brakes feel, but the car actually speeds up when i brake. Happened multiple times since i bought the car. So far no accidents.

While in motion when i pressed the brakes the pedal went to the floor. Brakes failed. Rapid beeping with brake light on. I pushed on the brakes and there was nothing. I did some research and this vehicles are having a problem with the brake booster assy. There is a recall for the same parts for the 2010 prius, not 2011 - 2015

Three weeks ago the brakes failed at a stop light on a city street and the abs and brake lights came on in the dash. The brake fluid appeared to be low so we opened a new bottle of fluid and filled the reservoir which seemed to temporarily remedy problem and nothing could be diagnosed because no lights were on in dash. The exact same thing happened again with the brakes failing and the dash lights coming on while at…

When i'm braking and slowing down gradually, as when approaching a red light, the brakes momentarily stop working and the car feels like it surges forward if it hits a low-traction surface like a pothole or manhole cover or wet spot. I saw there was a recall for this in 2010, but 2011 model consistently does it and has caused me and my friend to nearly rear-end other cars when driving my car. Apparently, it pertains…

The prius has a problem when braking over broken pavement or potholes. This happens when the brakes are applied to slow the vehicle and the car enters an area of the road where there is uneven ground. The brakes seem to not work for a second even if there is steady pressure applied to the brake pedal. This problem causes quite a startle to the car's driver. This is especially a concern to us when this happens at a…

Brakes disengage momentarily when braking on a bumpy roadway. I have had this happen multiple times. It feels like the abs system releases the brakes and then reapplies braking. Luckily, i have not had vehicles in front of me.

Every once in a while - it can be months between events - our prius momentarily slams on the brakes when driving at highway speeds while nothing else is going on. We know it's not operator error. It's happened to my wife several times and me once. When it happened to me i was driving straight ahead on a dry, lightly traveled divided highway during the day. Everything on the dashboard lights up, alarms go off, the…

While driving and braking on a bumpy road surface, the brakes will initially work, quit working momentarily, then reengage. This happens regularly. I just took it to the toyota dealership, and they say the brakes are fine and there is no problem. There was a toyota recall for this issue on 2010 models. I'm afraid this issue will cause an accident. How can i get toyota to address the problem?

There are 3 issues i am having with this prius. The brakes are the first problem. As others have stated, i too have the same lurching forward when braking over bumby or rough roads. This has been ongoing over the last few years. Second, the suspension is creaking and crunching when making turns at low speeds under 20mph. This happens when the wheels are turned all the way right and all the way left. This crunching…

On at least six occasions, i have lost control for a second or two while braking. While applying the brakes, and simultaneously crossing any sort of uneven terrain, the vehicle suddenly darted forward as i slowed. After reading a large number of similar incidents via a web search, i decided i needed to report this possibly dangerous issue.
