2013 Toyota Prius C service brakes problems

“November 2, 2026 approximately 1:37pm I was coming to a stop intending to take a left turn onto a Highway. As I applied the brake the car suddenly lunged forward almost throwing me into oncoming traffic at very high speeds. I was far too close to colliding or being thrown in front of a car that was traveling in the nearest lane. They took a lane change that was thankfully clear for them to do. This specific part of the highway had a fatality crash just 3 days prior. Suddenly, lights show up on the dashboard including ABS, brake, traction control and the warning light. The brake actuator assembly failed. From what I’ve seen this is a known issue that Toyota has acknowledged with a specialized warranty that my vehicle has aged out of. However the most crucial is I am well under the mileage for the part to have failed due to ware and tear. This was a manufactures fault. Tomorrow I will have the car inspected and confirmed that the failure occurred.”

“Car suddenly needed a jump start and again after a day or two of non-use. On the third day Brakes, ABS and traction control warnings were lighted up and remains. Brakes are mostly ineffective. My own scan returns the code C1252 and C1256 that says brake booster system failing. Took it to the dealer who charged $290 again to scan and came up with failed brake booster and pump assembly. The dealers is quoting total $4000 to fix. Toyota Customer Support Program Bulletin dated 8/2018 and revised on 8/2019 extends the warranty on for this issue (for Toyota Prius C 2013) for 10 years or 150000 miles. I was never informed by Toyota or the seller (Stevens Creek Toyota, San Jose CA) about this defect under warranty that I could have gotten repaired well before the dead line of 10 years. Now Both Toyota or the dealer's service department refuse to bear the repair cost.”

“Warning lamps for ABS and others and the chiming dings came on while pulling away from the bank drive through and parking for a second. I shut the engine off and turned back on with no success. I was barely able to park in a spot because of difficulties braking. My car had been making an electric noise every 15 seconds or so previously, at different times when parked, but I thought it was the hybrid engine. Now I think it was the brake pump trying to build up pressure due to a faulty, leaking brake actuator.”

“My 2013 Prius Plug-In Hybrid with 131k miles on it showed the ABS, Brake, and Traction Control lights while driving last week. Diagnostics from auto shop showed DTC code C1391. System is available for inspection upon request. Safety is definitely at risk, since I am needing to drive it around to assess the issue, and brakes could fail at any time. Vehicle has not been inspected by the manufacturer, police, insurance representatives or others. After speaking to Toyota, I was informed that--although under 150k miles--my car is not covered by the extended warranty because it is 2 years past the 10 year requirement. I drove my car very little between 2020-2022 because of the global pandemic. This is a very common issue with 2012-2015 models caused by a defective part, and it's likely that the problem does not commonly present itself until after the warranty expires.”

“Brake actuator went out on 2013 Toyota Prius Gen 5. The part is very expensive and in my opinion is a part that should not have to be replaced. The care has 120,000 miles. It is driven very softly, meaning not fast and hard but commuting to work and grocery store as needed. A nice commuter. It is not fast but gets you there. The actuator put me at risk as stepping on the brake was hard and the car did not want to stop and I was close to hitting the car in front of me. All the lights came on at the dashboard and I was very scared to continue to drive and had to get a tow truck.”

“I had my car serviced Oct 21 and when I picked it up the vehicle brakes made a whooshing noise and felt spongy. I thought it must be ok as they had just serviced it but when it became apparent this could be a problem I took it back Nov 1 and was told the hydraulic brake booster pump needing replacing at the cost of $3400. I was shocked as they told me it could break completely AT ANY TIME but the brakes would still work. I decided to drive it home as that is an enormous car repair bill and I would have to get financing or get a different car. I didn't want to make rash decisions. I investigated the issue and found out this was a recall for these vehicles for 2010 through 2019 models. This same dealer did not mention this to me at the time of sale, that they had been subject to a recall, and since I did not have them inspect the car immediately after service (I had to miss work and my son drove me after he was off work and I feared they would close before I arrived so I had them park the car outside and the sales desk had the key). I thought I would drive it but after reflection I do not want to endanger other people if my brakes fail. This is a clear violation…”
