TOYOTA PRIUS V

HYBRID PROPULSION SYSTEM: INVERTER

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2013-2015 Prius and 2014-2017 Prius V vehicles not included in recall 18V-684. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.

Risk: An unexpected hybrid power system shut down may increase the risk of a crash.

HYBRID PROPULSION SYSTEM

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.

Risk: If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.

HYBRID PROPULSION SYSTEM: INVERTER

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2012-2014 Prius V vehicles manufactured August 22, 2011, to June 30, 2014. A component within the hybrid inverter assembly may overheat, causing the hybrid system to reduce output power allowing the vehicle to only drive a short distance. In some circumstances, the hybrid system may shut down causing the vehicle to stop while being driven.

Risk: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.

AIR BAGS

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2014-2015 Toyota Prius V vehicles manufactured November 7, 2013, to January 7, 2015. The occupant classification system (OCS) that activates or deactivates the passenger seat air bag system may be improperly calibrated. As a result, the passenger air bag may not deploy in a vehicle crash. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection."

Risk: If the air bag does not deploy as intended, there is an increased risk of injury in the event of a crash.

EXTERIOR LIGHTING:TAIL LIGHTS

Genera Corporation (Genera) is recalling certain aftermarket replacement tail lights, model 11-6468-00 (driver-side), and model 11-6467-00 (passenger-side), sold for use on 2012-2013 Toyota Prius V vehicles. The brake light and tail light circuits are switched causing the brake lights to be illuminated continuously until the brake pedal is pressed, when the brake lights will go out.

Risk: The reversed tail lamp function reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash.

SERVICE BRAKES

All ABS, Brakes light on, code 139. Its been making a buzzing noise for a couple of years, the noise got shorter over time, and finally was coming on every 5 second, and finally the dash brake lights came on. I've cleared a couple of times, but the lights come back on after a few miles. The brake pedal has to be pushed down hard to stop. The problem is the brake part is $1500, and 1500 to install.

SERVICE BRAKES

I have a 2014 Prius V with 92,000 miles. My anti-skid, brake and ABS idiot lights went off approximately 1 week ago. (August 25, 2025) Scheduled an appointment at my Toyota dealer (September 3, 2025) and was told there was an abnormal leak in the accumulator and that the brake booster pump and brake pump assembly needed to be replaced. Cost $5715. Not related to the brakes, but they also said I had to replace the rear shock absorbers as they are leaking and needed to be replaced and then realigned. Cost $1363. This should have been a recall not a mileage or 10 year limit.

SERVICE BRAKES

Prior to issue, noticed a buzzing sound from engine compartment, later known to be the ABS accumulator pump, occurring more frequently - first multiple times when braking, then later continuously while driving. Dashboard eventually lit all brake-related warning lights ("BRAKE", TSC, ABS) and brake pedal behavior changed markedly. This occurred after parking in my driveway while engaging the parking brake. Brake behavior during and after this period was wildly inconsistent and impossible to predict. At times the brakes would perform normally, but most often the first portion of brake pedal travel would have no braking effect, and actual required force on the pedal to brake was greatly increased. The need to press further and with more force created a dangerous situation as it delayed how quickly I could slow or stop. The inconsistency in performance created a dangerous situation as the vehicle may (and did) sometimes stop more suddenly than expected. Additionally, the failure resulted in loss of traction control and ABS resulting in greatly increased risk in wet road conditions and terrible danger in sudden-stop situations. Self scanner & Toyota service center confirmed presence of C1392 code and recommended replacing brake actuator and brake pump assemblies, quoting over $4,500. Service was declined and replacement parts bought from Toyota and self-installed to resolve issue. Both Toyota service center and Toyota customer support line confirmed that this issue was described in an existing Customer Support Bulletin but that coverage was denied due to age of the vehicle. Vehicle was approximately 15,000 miles below listed mileage cap but approximately 12 years old, with Toyota denying service for vehicles over 10 years old.

SERVICE BRAKES

C1391 - Abnormal Leak of ACC Pressurization. Bad Brake booster assembly.

SERVICE BRAKES

Toyota has a break issue that they extended the warranty for 10 years or 150000 miles and now a few months pass the 10 years I have a problem with the actuator giving warnings and my daughter went into a skid when applying the breaks. She was lucky and didn’t hit anyone. If Toyota knows there is a problem that is a safety concern they should fix it I did get a Toyota dealership to give an estimate to fix it and was told $4300.00 I think that’s too much for a defective part. It should be a safety recall.

SERVICE BRAKES

While driving on the highway, all the Brake-Related Warning Lights appeared on the dashboard. This was accompanied by a frequent electric buzzing noise (every 15-20 seconds, lasting two seconds each time). The brakes became difficult to press, almost spongy, and required more pressure to function. Upon taking it to the dealer, I was told that the vehicle (a 2013 Prius V with 181k miles) needed a new ABS pump and brake actuator, totaling roughly $4100.

SERVICE BRAKES

ABS Brake pump actuator booster failed. It is available for inspection. While driving, I started hearing a hissing sound from my brakes. I tried to slow down and my several diagnostic lights (ABS, traction control, brake, check engine, etc.) flashed on while my brakes failed to work properly. I turned on my hazard lights immediately. I was in the middle of the road with my toddler in the car and I almost rammed into the car in front of me. Luckily I was able to pull into a turn lane and pushed with all my might on the brakes and it finally was able to stop. My brakes failed and I could have hit the cars in front of me and hurt my child, myself and others. It was terrifying. Problem has been confirmed by an independent service center. The warning lamps only appeared WHILE the issue was happening and my brakes failed to work properly.

SERVICE BRAKES

The brake accumulator has failed on our 2013 Prius at 170K miles. The brakes are unresponsive and all brake-related indicator lights are on. The vehicle is unsafe. This is a known issue for this model and year Prius, yet Toyota did not issue a recall. Warranties were extended to 150K miles, but this issue is a serious safety risk - danger to us and others on the road. This issue should have resulted in a safety recall, not a "courtesy" warranty extension. Toyota needs to resolve this for all affected vehicles.

FUEL/PROPULSION SYSTEM

The car stalls randomly and does not enter fail-safe mode. The dealer says it is the transmission but the transmission has never shuddered or hesitated. I am reading that these vehicles have intelligent power modules in the hybrid inverter that fail and can cause stalling. I feel like the dealership is working with Toyota to avoid addressing the actual problem. In the meantime I was sent home in a vehicle that continues to stall randomly and does not enter fail-safe mode.
