2013 Toyota Prius: check engine light

Filed Feb 9, 2026 · Brakes · FL

I was driving and notice ABS light and other light came on, then noticed that when I tried to brake it felt weak, had to pump brake, then later noticed a leak on brake fluid. I took car to Toyota and they checked it and said brake booster and booster pump needed replacing and they wanted to charge me 3,000 dollars. I could not do the job so I checked around and the auto one in my area informed me that many Toyota Prius’s had a recall on that issue. I made an appointment with Parks Toyota in Deland, Florida to fix problem but when he got there they told me that my car was not on recall for that but was for battery EV fuse but couldn’t do because my engine light was off. I am having such a difficult time with this car. I cannot risk my life and that of others driving with this brake condition if I can’t have the manufacturer or who ever has to to take care of this issue. So far I was able to get a mechanic to do some adjustments so I can drive. I am being very careful and only use it as needed. I stopped looking for a part-time job because I need this fixed first. I am [XXX] , please tell me if I am able to get this recall show for me. Thanks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crack in the Engine. I had been following the recommended Maintenance schedule, but I suddenly had issues where the engine would stall/stutter on activation (switching from electric to motor operation). The check engine light came on, and I immediately took it to the dealer who replaced the battery and spark plugs saying that was the issue. That solution did not even last a month, as I had sometimes severe shaking in the engine along with the stutter. I again brought it to the dealership who told me that the actual problem was a cracked head gasket and that the vehicle was "mechanically totaled". I was lucky that I live close to the dealership and worry what would have happened if I had to drive on it further.

While driving on the highway, ABS, "Brake"/E-Brake, Traction Control Lights lit up all at the same time out of the blue. No prior engine lights/codes before this incident. During that trip, brakes felt more difficult to press, loss all brake regeneration for the hybrid battery but was still about to brake for that entire 100 miles trip. As of now, the car is still able to brake but it looks like it's just primarily using the mechanical brakes all the time now. It still has that different brake feel compared to when before all those engine lights went on. Regenerative braking is no longer working. Brought the car to the shop at was given the error codes C1391 and C2315.

I keep getting a p0136 bank 1 sensor 2 error code. Took it to several mechanics and they switched the 02 censor (downstream). Also shows that bank 1 sensor 2 has 0% voltage. Unplugged the downstream 02 sensor and got a reading but no reading when plugged in. Checked wiring harness to ECM and everything was fine. Both mechanics have determined that the issue is with the ECM. My vehicle has roughly about 70k miles on it. My car will not pass smog until this is fixed. Mechanic is recommending reflashing ECM or replacing it. P0136 comes up as pending and will stay permanent on the second drive cycle. Check engine light stays on.

Engine warning light at start up came on with no degradation of operation. Car was taken to originating manufacture dealer for diagnosis. When car was purchased as certified pre-owned the sales rep upsold extended 3rd party warranty coverage that they said 'would cover everything including diagnosis labor fees.' when vehicle was diagnosed from dealer service dept they said it was faulty o2 sensor, caused 'by rodent damage to cable'. No validation or evidence of this was provided; cable/parts not presented for inspection to customer. Customer was told lack of sensor would result in reduced gas milage. Customer asked about safety of vehicle and was told vehicle was safe to drive without part repair. Customer asked if repair was covered under warranty and was told that it was not. Customer declined repair at that time; customer was forced to pay ~$150 labor charge for inspection. Customer returned at a late time to complete repair. Again no evidence of part failure was presented and repair cost ~$400 was forced to be paid. Customer then found extended warranty coverage documents and called them to ask why repair was not covered as program documentation and contract seemed to include coverage of this issue; provider noted that dealer did not call to authorize repair at no cost to customer and customer should submit paperwork to provider for review. Customer further researched on internet the issue and found multiple reports of faulty wiring and is concerned for safety of operation due to manufacture material flaws that allow animal damage to critical wiring of car.
