2010 Toyota Prius: sudden loss of power

Filed Jan 25, 2025 · Engine · NY

I own a 2010 Toyota Prius hybrid 4 door sedan. I am the second owner of the vehicle. I purchased it in 2018 from a used car dealer. The vehicle ran well up until 2022 where a “check hybrid warning would appear on the dashboard along with a yellow triangle and service engine light would come on and the vehicle accelerator would not respond and the car would have to glide to the side of the parkway. This problem would happen when the car speed is between 60-70mph. It is very dangerous to lose power on the highway because many times there is no where to pull over. In 2024 I changed the water pump because the fault code on the cars built in diagnostic code read error “P216B” which is the cars electrical water pump signal. I researched it on google and a lot of 2010 Prius owners are complaining of the same thing. Also the changed water pump from April 2024 died again in January 2025. It is very scary that the cars accelerator pedal goes unresponsive and all the fault lights come on. My vehicle has 155,000 miles runs great and my family loves the 40mpg it gets. However, this stalling problem is being ignored by Toyota and could lead to a fatal car accident if not recalled by the manufacturer. To conclude, I would like for your office to possibly conduct an investigation with the 2010 toyota Prius hybrid for this ongoing problem that the company is ignoring. This is a serious issue and can possibly lead to a fatal accident. THANK YOU FOR HEARING MY COMPLAINT AGAINST TOYOTA.

Please read the attached file "prius complaint signed" for a full description. I am the owner of a 2010 Toyota Prius, 2ZR-FXE. The warning light came up on my dashboard of my vehicle, so I took my 2010 prius to AutoZone, to get a free diagnostic. The diagnostic indicated the problem code of “C1256” “Accumulator Low Pressure” for the “Anti-Lock Brake System.” See Ex. A (AutoZone Diagnostic). It is available for inspection. According to the safety recall number “D0H”, 2010 prius model “2ZR-FXE” has a “Brake Booster Pump Assembly which can develop a crack inside the accumulator housing. If this occurs nitrogen gas could leak into the brake fluid and gradually cause a loss of power assist. Under certain circumstances, THIS COULD AFFECT STOPPING DISTANCE AND INCREASE THE RISK OF A CRASH.” (Emphasis added). I have noticed that when I brake hard, IT TAKES LONGER TO COME TO A STOP, WHICH THREATENS NOT ONLY MY LIFE, BUT THE LIVES OF MY WIFE AND TWO [XXX] DAUGHTERS WHO ALSO RIDE IN THIS VEHICLE. According to the safety recall, “Toyota dealers will perform an inspection and, if necessary, replace the Brake Booster Pump Assembly at NO CHARGE to the vehicle owner . . .” See id. The safety recall does not explicitly permit dealers or servicers to charge for an inspection with regards to this defect, according to the information provided me. The estimate, provided by DARCARS recommending replacement of the “BRAKE BOOSTER WITH MASTER CYLINDER WITH PUMP[,]” confirms that the issue appears to be that which is covered by the safety recall. Ex. F.; see also Exhibit B Safety Recall (The vehicle has a “BRAKE BOOSTER PUMP ASSEMBLY WHICH CAN DEVELOP A CRACK INSIDE THE ACCUMULATOR HOUSING . . .”). See also Exhibit E Error Code from DARCARS (“C1256 Accumulator Low Pressure”). Nevertheless, DARCARS refused to waive the diagnostic fee of $150 and would not repair the vehicle unless I paid them “$5,150.” See Exhibit F. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Affected by the recall number 10V036000, the 2010 toyota prius is manufactured with a defective brake booster and master cylinder system which causes defect of the brake system, and causes my vehicle to often lose power in abs and randomly lose abs power braking, making brakes hard, and makes for longer stopping distance. This is a problem for many and obvious reasons on the road regarding safety. All vehicles should have optimal braking systems for the road, and should otherwise be repaired at no cost if the car is manufactured with defect. This has caused no accident for me yet but the abs has failed on many occasions. I have read at least 100 cases of this given vehicle under this recall being caused an accident with faulty brakes, and sometimes complete failure to stop which is extremely worrying. This recall excludes vin numbers past a certain date, yet the recall in question is certainly still affecting many cars, as capistrano toyota has also called for petition of toyota to repair at no cost for all affected vehicles. Yet all dealerships have denied my request and toyota has no formal coverage regarding the rest of the faulty vehicles they manufactured.

Brake booster failed while driving. Warning light ABS, traction control and brake light lights up. Lost power brake. Car is hard to stop with the manual brake in the fail safe mode. with C1391 code logged. Toyota had an ZJB warranty extension but my car is not covered because the warning light did not show during the 10 year window. The brake booster fail appear common and should be cover by a recall instead of a warranty extension.

While driving at highway speed on Interstate 87 in New York, the 2010 Toyota Prius suddenly lost power while multiple warning lights on the dashboard illuminated, along with a "Check Hybrid System" notification. The engine would operate but at significantly reduced power. I drove it to an independent garage to identify the diagnostic trouble codes, which included P0A94 and P324E, an inverter problem with the hybrid battery and a problem with the intelligent power module. The currently is currently awaiting a confirm diagnosis at a Toyota dealership in New Jersey, but the problem is exactly what thousands of other 2010 - 2014 Prius owners have reported, yet Toyota has yet to issue a recall to replace the inverter.

I was driving down the highway, I hit the gas pedal to accelerate faster through a light that had just changed from green. As soon as I did that my car lost power and a bunch of emergency lights came on, I immediately got on the shoulder. No one was behind me otherwise I would've been in a wreck. I turned the car off and on again and the emergency lights were still there. I was able to drive up to about 10 miles an hour a few blocks to a parking lot. I had the car towed to the toyota dealership and they told me it was my inverter that over heated and needed to be replaced.
