My Toyota Prius 2012 with 95K mil. ABS, traction and brake lights came on while driving on highway, the breaking wasn't like used to be, it was mushy after the warning lights, took it to Toyota dealership they estimated $3500 for the brake replacement the fault codes C1241, C1247, C1391 found break booster and pump assy, needed. This should be recalled by Toyota, its safety issue, I have owned the car since it had 41K miles and regularly maintained the car throughout my ownership period.

My 2012 Prius was diagnosed at our Toyota dealership. They said it needs a brake booster/solenoid. When I looked into it, it seems that this has happened to hundreds of consumers with Prius cars from the same era. It is a devastating $3,000 repair. Total injustice if it is a manufacturer issue as it seems.

ABS warning light indicating trouble with the braking system, I took the car to an independent auto repair store and the mechanic checked the codes on his computer and received 2 codes that indicating that the ABS pump needs to be replaced. The total cost would be between $3000 to $5000. The ABS light goes on when I start the car

I have never received a recall mail regarding the car. I used an insurance tracking plugin, and all the problems started.pcs error message on my dashboard, due to a leak in brake booster they said. My dealership will not tell me it's a recall, made it seem like they helped me instead of charging as high as $4000. I was not given a loaner car for the 4days they had my car, and did not get any refunds for the rental car I got

The problem started with a chirping noise when the brake pedal is depressed. Today the car appears to lose regenerative braking charging. The vehicle stability control and ABS light and brake light came on. The brake appeared to be mushied.

More than once I was driving about 40/45mph, once on a curve, anyhow as I was going through the curve it felt as though the brakes engaged, without me touching them. I understand the safety thing, however at both instances it was not necessary. It caused the car to pull to the left. Almost causing me to loose control.

I started my car and my dash lights for brakes, anti-lock, anti-skid came on and brakes became spongy. This happens intermittently. I parked the car and later checked the lights and the car was operating normal. I drove the car around the neighborhood to try to duplicate the issue. Could not duplicate. The next day I started the car the lights came on again and brakes were not operating normally. Spongy and no anti-lock. I checked recalls and found the issue was recalled in 2010. I also found numerous complaints on Prius forums for this issue covering 2012 Prius. I think this is a safety issue Toyota should recall for 2012 as well.

Car was in motion and brake pedal went half way to floor and ABS, brake, traction control and tire sensor lights came on. Master cylinder or brake booster seem to have failed. Dealer didn't recognize codes and could only recommend changing spark plugs when I just had them replace 6-8 months prior. Explained that did think that had anything to do with brakes giving out. They reset codes and sure enough happened again within the next 30 days. Toyota admitted to since receiving many reports of certain internal malfunctions of brake booster assemblies. 4 trips later to dealer the response is the codes are not coming up (dtcs) C1391, C1252, C1256 or C1253 in order to be covered it's voluntary customer support program which has brake booster and brake booster pump coverage. Very frustrating!

My car has the same brake booster/master cylinder defect that the 2010/11 model Prius were recalled for. Brake booster or brake pressure accumulator failure on 2012 models causes loss of braking effectiveness. Serious safety issue that can cause death. Toyota is well aware of this. This happens in motion at highway speeds.

Vsa, avs, and brake lights on with decreased resistance in petal. Brakes will return to normal without warning periodically while driving. This makes driving and stopping unsafe and unpredictable.

I having a problem with the brake booster on my Prius and the Toyota dealership I went to said I need to replace both the master cylinder and booster pump which would be 3000 dollars worth of parts and labor. After research this issue I have found serval people have the same issue. Also the parts are on back order, showing you how big of issue this is. The breaking system felt spongy, my traction control braking system and ABS lights came on. Thankfully I had just a couple of feet to my driveway.

  • 58,000 miles
When the brakes are applied and going over a rough road surface, or pothole, the brake warning light appears, and the brakes suddenly stop functioning until back on a smooth road surface. This happens all of the time under these conditions. It is really scary when the vehicle suddenly loses all braking while trying to stop. I have a 2012 Toyota Prius and a 2010 Toyota Prius. They both have the same problem with the ABS braking system. Cannot understand why this is not a full recall on this potentially dangerous condition.

Feb 262019

Prius

  • 70,000 miles
The car has been suffering all of the brake symptoms for the recall of the 2010 Prius brake booster system. I've repeatedly complained about losing braking power when the ABS light comes on when I go over uneven surfaces such as railroad tracks or a pothole. The brakes have benn farting from day one while sitting at a light or parked if the brakes are depressed and then slightly released. And now today the ABS brakes are on with the battery light and there is limited braking power. I have to push almost all the way down before the brake engages. Toyota tells me I need to replace the brake booster system for $3500 and there are only 70,000 miles on my 2012 car. I feel my brakes have the same issues as the 2010 recall and more years including mine are affected and should be recalled.
