2013 Toyota Prius V

My Prius had brake warning lights come on around December 2025. Turns out the brake accumulator had an internal leak. After doing some research, I discovered this was a known brake booster issue that Toyota has not issued a recall on. They do have an extended warranty program, but my vehicle did not qualify. The warning lights did not come on until after the 10 years or 150k miles cutoff for the warranty. Toyota's refusal to issue a recall and limits of their warranty program are clearly a move to avoid paying for repairs incurred as a result of defective manufacturing. Why should I be ineligible for reimbursement just because my vehicle is 13 years old rather than 10? Please make Toyota issue a recall or extend their Customer Support Program No. POL18-03.

Suddenly Cars Brakes failed with vehicle almost lunged forward. I had to slam the brakes heavily for it to stop; Took the vehicle to Toyota Service and clearly its a QUALITY issue toyota acknowledged as a know problem with error code C1391. They even had customer support program 20TE07 acknowledging it as their issue; I almost got killed for this. The repair costs are abnormally high at 4900$'s putting me a financial burden also and currently unsafe car; Toyota - they literally KNOW THIS ISSUE and still put me at risk. They are refusing any kind of assistance to help too.

The harness webbing/strap on the Evenflo Revolve360 Slim tore without any known incident or accident causing the damage. The defect was discovered on April 15, 2026 when the seat was temporarily removed from the vehicle. Upon inspection, the harness strap was found to be nearly completely torn through and would likely not have restrained the child occupant in the event of a crash. The seat had been in regular use and had not been involved in any collision. No unusual event or misuse is known to have caused the failure. It is suspected that the rotating mechanism of the seat placed repeated stress on the harness webbing over normal use, causing it to deteriorate and tear. The seat has not yet been inspected by the manufacturer, law enforcement, or insurance representatives, but is available for inspection upon request. The seat has been taken out of service and is not being used.

The contact owns a 2013 Toyota Prius V. The contact stated that while pulling out of a parking space at approximately 15 MPH and depressing the brake pedal, the brake pedal felt spongy, but the vehicle responded as intended. The brake, the ABS, the traction control warning lights, and an unknown warning light were illuminated. The contact scanned the vehicle with a code reader and retrieved diagnostic trouble codes for the brake booster and brake accumulator systems failure. The contact related the failure to the Toyota Customer Satisfaction Program: 20TE07 (Certain 2012 - 2014 Model Year Prius V Coverage for Brake Booster and Brake Booster Pump Assemblies). The manufacturer was contacted and informed the contact that the vehicle was no longer covered because the 10-year limit was exceeded. The contact was referred to the dealer, who provided an estimate for the repair. The vehicle was not repaired. The failure mileage was approximately 120,000.

When I'm in the car, the brake booster keeps recharging with out touching the brake pedal. Also, the car has problems when I apply the brakes while driving. They make a hissing and popping noise and the braking is spongy. I have had braking warning lights come on as well. It is similar to what others have been describing as the brake booster and pump actuator issue with these Prius V cars. This has been happening ongoing for about two years or so. I called the Toyota dealership and they would not check it out for free or remedy the issue that was part of their Customer Support Program (Policy 13V-235) for booster pump issues.

Upon a hard (but not emergency) brake, my ABS and brake warning lights came on and my car began whirring once every few seconds. I immediately took the car to the Toyota dealership, who informed me that my master brake cylinder and booster had to be replaced, and that issues with the booster were something they had seen frequently in this generation of Priuses. I paid $5095 for repairs and inspection, but I had no other choice, as my brakes could have gone out at any moment whilst I was on the road and caused a very serious accident.

OBSOLETE NOTICE February 13, 2026: This bulletin is now obsolete. Please see T-SB-0009-26.

This bulletin includes basic procedures for performing a rescue charge on Ni-MH high voltage (HV) batteries. This bulletin should be used in conjunction with the applicable model and model year Repair Manual while performing a rescue charge. The GRX-5100 should be used wherever the Repair Manual references the Toyota Hybrid System (THS) charger.

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.

The air conditioning dye injection tool kit has been developed to aid in identifying the location of air conditioning refrigerant leaks. The procedures outlined in this Service Bulletin aid in locating, inspecting, and repairing refrigerant leaks.

Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: •Minor damage: requires only buffing to repair. •Moderate damage: usually requires neutralizing, color sanding, and buffing. •Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
