2009 Toyota Prius: check engine light

Filed Oct 9, 2024 · Brakes, Driver assistance · WA

The engine light went on while driving on the highway. We immediately pulled over and had the vehicle towed to the nearest dealership. The dealership informed us that both the Brake Actuator (Toyota part TO44500-47141) and water pump (Toyota par TOG9020-47031) had failed. The car was no longer save to drive.

The hybrid water pump failed/ aka the inverter coolant pump. This was recalled years ago and has failed again. The previous owner of my car replaced it in 2013, so Toyota is refusing to replace it again, despite the fact that the part is faulty and has compromised the safety of my vehicle. This issue was diagnosed by a mechanic yesterday, error code P0A93. The master warning light, check engine light, brake light came on. The AC stopped working. The brakes nearly gave out on me driving on a bridge in New York City. This part was recalled. Toyota refuses to honor the recall a second time. They clearly did not properly engineer this part! It failed again! They should be responsible for fixing this issue.

My car recently has a check engine light and the obdii scanner show the fault code p1121 which is a failed three-way coolant control valve. Toyota has issued a technical service bulletin (tsb) on this problem: eg001-08 m.I.l. It should be a recall because it's a common problem for 2nd generation toyota prius.

Service engine light, code p1121, coolant recovery tank flow control valve bad. There is a service campaign on this for 2007 prius and the problem is supposed to be solve for 2009 prius. Also this is part of the emission control system, as the purpose of coolant recovery tank is the warm up engine sooner to pass emission test. Called toyota dealer, not covered by emission warranty. This is a known and very common problem and toyota is dragging its leg on it.

When my 2009 toyota prius reached approximately 65,000 miles, the check engine light came on, and the error code was p1121, indicating a problem with the coolant control valve. I took the car to my local toyota dealership, and their charge for replacing the part was $400. The mechanic who inspected the valve said it was not closing securely. He said making the repair would not improve the car's performance or affect its value, and therefore he did not recommend making the repair. Unfortunately, I have realized that opting out of this repair does affect the car's safety. The check engine light is constantly on. Even if I manually turn it off, it comes right back on, so it is unlikely that I will be aware if other mechanical issues ever arise. My mother drives a 2008 toyota prius which just hit 65,000 miles, and her car produced the exact same error code. It is statistically impossible that two cars of the same make and model, only a year apart in age, in the same household, would produce identical error codes after reaching roughly the same mileage for any reason other than defective manufacturing. I believe this error code is the result of a manufacturing error that toyota should address through a safety recall. Toyota's own mechanic admitted that the repair is financially impractical for customers, yet if the repair is not made, drivers are left without a functional check engine light which is a safety hazard.
