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.
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.
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!
Traction, brake and abs lights all came on at once, pratically lost all braking while driving but able to slowly stop. squishy brakes. "pump" sounding noise like it's having trouble pumping brake fluid.
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.
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.
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.
I was coming up the freeway off ramp and my car just turned off i had no braking i hit six other cars rolled over and was severly imjured in the hospital forr three days
Problem with braking system involving, the other day the car was on and suddenly three (3) warning lights came on: brake light, abs light and traction control light. there is also now a pumping sound coming from under the interior of the dash (on it at least sounds that is where it's coming from. the car has 151,428 miles on it. i've included pictures of the current eror code, mileage and dash lights that are on.
The vehicle was traveling over 60 mph when the abs, brake and traction lights came on and the brake became immediately spongy and i had to depressed even harder (past the foaminess) to reduce speed. a motor could be heard trying to turn over on the brake system. the car speed was reduced to 25-30 mph on the highway but the spongy brakes continued. within 5 min i pulled off the highway and into a parking lot. parked the car, turned it off and on to see if that would remedy the situation and nothing changed. i then called the toyota dealership's service department to book an immediate appointment and arrived at the dealership approximately 40 minutes later. the car was looked at and i was told that the brake actuator was the issue and that they would like to contact toyota to see if this was in warranty or part of the recall. i was told the next day that the cost of installation and parts would be at least $4,000 and that i would need to pay the full amount as toyota was taking no responsibility. i called the toyota customer service line, explained my situation and was ...
Brakes failing, getting a c1391 code, leak in accumulator. toyota has a warranty enhancement for this issue on the 2010 model but it has not extended to 2011 or 2012 models. i contacted local dealer and national representatives and was refused any assistance from toyota. this issue happened twice over the last two days, both times while vehicle in motion on a city street. warning lights came on and almost no stopping power.
I was traveling north on the highway. i was going between 50 and 55 mph when the traffic light turned to yellow and then to red. when i applied the breaks nothing happened. my vehicle actually appeared to speed up. i released the brake then pumped the break twice then again applied the break, this time stomping harder and with both feet. my vehicle did not stop or even slow. i went through the light, resulting in a car accident. i t boned another car.
Various alerts lighted, brakes, abs, anti skid. lost some braking... too soft and funny like... needed pumping. cost of repair to replace brake pump system including tha actuator(buster). brake pads for $3,700 +. at toyota calesa in puerto rico.
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.
The brake light, abs light, traction control light all came on at once while driving normally. it did not affect the drivability of the vehicle. i took it to the local toyota dealership to diagnose the problem. the service specialist said that this is a known problem with these cars and quoted a $2500 service price to replace it. if it is this known and this expensive to replace then it should be included in a recall. that would make it a design flaw by the manufacturer.
