- Wellington, FL, USA

Brake booster and actuator failed and error code C1391. Vehicle is unsafe to drive and Toyota knows this problem because of the number of cases involved with this issue. The year prior saw a massive recall of 87,000 vehicles with the same issue. The same issue has carried over and Toyota refuses to be held responsible for this issue.

- Orlando, FL, USA

Brake actuator has gone out giving a code of C1391. I have had the car less than a year and the brakes are now grabby and not functioning properly. This is a known problem with the gen 2 Prius (my previous car) and was covered under an extended warranty. Apparently the gen 3 Prius has the same issue and Toyota has extended the warranty of the 2010 Prius to the manufacturing date of 11/2010. My Prius was manufactured in 12/2010 and I was just notified it would be $4000 to fix the issue that is a known manufacturing defect. Apparently Toyota didn't fix the problem the first time and it's a direct safety issue when the brakes don't work as intended.

My car only had 120K miles and the break boostor and actuator breaks down while we were on the road. My wife drives the car with my 3-childrens. She was almost hit the other car on highway because the breaks system stops working at normal mode. The dash board shows all kinds of break, traction control, and ABS lights. This is a life threatning issue and toyot needs to replace this part with no charge becasue it has a manufacturing defects and thousands of Prius owner has the same issu.

The problem my car experienced happened while the vehicle was in motion on I-110 in pensacola, Florida and presented itself abruptly (through the car's warning indicators at least) on Friday, August 31st headed to pensacola beach for labor day weekend from our home in baton rouge, Louisiana. All the car's brake warning lights came on simultaneously and without warning, the master brake light, the ABS light, five different lights in all. I pulled off the interstate, went to an autozone store, checked the brake fluid level and brake pads (all looked nominal) and got the car's computer checked for warning codes (none came up). Seeing nothing catastrophic, but being unsure of whether our car was really safe to drive even though the brakes still felt functional (if a bit off), we got the car back to baton rouge and brought it to the local Toyota dealership's (all-star Toyota, on airline highway) service department. We had noticed for some weeks prior increasingly frequent buzzing sounds ' anyone with a Prius knows these, such as when you turn the car off ' made by (I'm told) the car's brake actuator pressurizing the brake fluid. This escalating frequency of the noise, and a certain constant 'pulsing' of the sound when the brake was slightly applied, but not pushed down to the floor ' I now understand to be symptomatic of a failing brake actuator. Following some research, I discovered in 2013 Toyota issued a recall for thousands of 2010 Prius and other Toyota automobiles for a problem with brake actuators; also, in 2016, a warranty extension and part replacement was offered to hundreds of thousands of 2004 through 2009 Toyota Prius vehicles for problems with brake actuators. In that more recent matter, owners were offered a warranty extension to 10 years after first use of the car or 150,000 miles, or unlimited mileage or age up to the end of 2017.

Takata recall my 2011 Prius has an issue where the brake becomes spongy at random while driving under normal conditions. The brake, ABS, and traction control lights all illuminate simultaneously. After resetting the computer, the issue comes back within 10-30 minutes of driving at random. Toyota told me it is a $3,000 fix and there is no recall for my year. My car has 110,393 miles.

- Cutler Bay, FL, USA

Driving vehicle down highway, tapped brakes but brakes did not work, all the lights on my dash lit up. I lost traction in brakes causing vehicle to lose control.

- Oxford, GA, USA

4 lights came on my dashboard: Brakes, ABS, etc. So I took the car to the dealership. They said I need a new brake accumulator but it isn't covered and is a $3500 repair. I see that the 2010 Prius was recalled for this same part but they won't cover mine.

- Providence Village, TX, USA

The traction control light, antilock brake system not funtion and the light stays

- Snellville, GA, USA

Got in car one morning and all the brake / traction control system related lights are on. Turned car off, waited 10 minutes restarted car and lights are still on. Tested brake function in yard, reduced but still able to get car stopped. Took it to shop and read codes, came back as the actuator which is already recalled on previous year model pruis', obviously they did not fix the issue on the early gen 3 models (2010 & 2011). I have found multiple other people with gen-3's that have had the same issue os these should be included in the gen-2 recall because they are having the same issue. With it being a dealer only part at $4500-$5000 (parts and labor) to fix on a car that's only worth about $10,000 I wonder if it's really worth fixing. At this point the car is parked because with the diminished braking performance I don't feel safe driving it.

Brake actuator failure. ABS, traction control, and brake light all on dashboard. The car has no regenerative braking. Issue occured randomly while in motion.

- Palm Harbor, FL, USA

Brake accentuator failed - no warning and traction control/brake light/ABS warning lights all illuminated. Hard breaking test @25 mph confirms ABS not working (I.e. tires skid) and breaking distance adversely impacted for normal braking. Hybrid system charging from braking is diminished.

- Valrico, FL, USA

The traction control, ABS light and warning light all came which I believe all to be a safety issue

- Katy, TX, USA

The vehicle takes long stopping distance while braking and, also L had many times when the car slipped while braking

- Fitchburg, WI, USA

While driving on the highway all the break lights came on and stayed on brake, ABS and skid lights on also noise under hood by brake master cylinder. Took it in to the dealership and they verified ABS / brake lights on). Told me I needed to replace brake actuator / brake booster pump / bleed / and re-flash system. Found out this also has been happening on the 2009 and the 2010 Toyota Prius hybrid and they have a recall out on this. I was told at the dealership that it was unsafe to drive the vehicle with this occurring

On uneven road surfaces (washboard road, many small potholes, gravel roads, rough road shoulders) brakes would give out if braking hard. If felt like once ABS kicked in the brakes would get almost completely released. The car would brake just fine on flat surfaces, wet or dry. I have multiple vehicles and know how ABS brakes work but thought the Prius brakes were just a bit more sensitive and I have to watch my distances more carefully and avoid hard stops. Then on April 23, 2018 the car started to make some strange noise but no dashboard lights came on. I continued driving and noticed the brakes were working only intermittently. After I almost crashed when attempting to break in traffic I limped back home and took the car to the dealership. The repairs to replace brake pump and cylinder assemblies cost $4,193.31 but the car was driveable again. However, I noticed that the repairs also corrected the ABS problem that was present since the car was new. I think anyone who drives a 2011+ Prius should get their brakes checked for emergency braking where brakes stop working thus allowing the car plow ahead even if the brake pedal is down to the floor.
