What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I keep replacing P1116 and it keeps coming back also I was driving up a hill when I lost power and the car wouldn't accelerate. It would turn on and go into gear but not go anywhere. I know it says my vin doesn't have recalls but why am I experiencing them”

“The contact owns a 2007 Toyota Prius. The contact stated that while at a stop light, she attempted to drive however, the vehicle failed to exceed 25 MPH. The HC battery, ECU, and check engine warning lights were illuminated. The vehicle was towed to an independent mechanic, who informed the contact that the vehicle displayed DTC code: P3190 (Engine Failure). The vehicle was towed to the local dealer, where it was diagnosed that the hybrid battery was severely drained, and the mechanic retrieved DTC codes: P3000 and P0A80 for the hybrid battery pack. The vehicle was not repaired. The vehicle was towed to another independent mechanic, who replaced the battery, but the failure persisted. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 160,000. The contact stated the vehicle was actually overfilled with oil at the mechanic's shop that performed the oil change, so that is what caused the issues with my vehicle.”

“I was driving and all of my dashboard lights disappeared, I couldn't see anything. I was suddenly driving blind. I pulled over but the car would not turn off. I tried again and again, but it would just not turn off. I called Toyota corporate they asked how far I was to a Toyota dealer and told me to take it there immediately. They gave me a case number 220322000191. When I got to the dealer, they said I would have to pay $150 for a diagnosis. I left it there and am now reporting this. There should be a recall on these vehicles, this is extremely dangerous.”

“2007 PRIUS 144K MILES WHEN PROBLEM 1ST OCCURRED. CAR SERVICED REGULARLY - OIL CHANGED EVERY 3500 MILES. MASTER WARNING LIGHT WOULD COME ON RANDOMLY WHEN TURNING OR GOING UP/DOWN HILL AT HIGHWAY SPEEDS. COMPUTER DIAGNOSTICS RUN REPEATEDLY (AT TOYOTA AND AT LOCAL MECHANIC) NOTHING EVER FOUND. 12/2016 BROUGHT CAR TO TOYOTA SERVICE COULDN'T FIND ANYTHING INITIALLY. 2+ HOURS LATER TOLD OIL IS VERY LOW WHICH MADE NO SENSE; NO OIL SPOT IN GARAGE, CAR PASSED INSPECTION AND WASN'T DUE FOR AN OIL CHANGE . WAS TOLD THE 'OIL WARNING INDICATOR' WAS LIT DESPITE THE FACT THAT THE OIL WARNING LIGHT NEVER CAME ON. EVER. (OIL INDICATOR SHOULD COME ON WHEN CAR IS STARTED AND REMAIN ON -BRIEFLY IF THE OIL IS LOW. IT DOES NOT.) TOLD TECH THAT ONLY THE MASTER LIGHT COMES ON AND THE CIRCUMSTANCES. NEVER GIVEN AN EXPLANATION. PROBLEM HAS GOTTEN PROGRESSIVELY WORSE. MASTER INDICATOR ONLY COMES ON WHEN THERE IS ALMOST NO OIL. LAST TIME THIS HAPPENED I ADDED 4 QTS. OF OIL, DROVE 687 MILES AND HAD TO ADD ANOTHER 4 QTS. AT THIS POINT I HAVE TO CHECK THE OIL EVERY TIME I GET INTO THE CAR.”

“I WAS DRIVING MY CAR ON THE HIGHWAY IN HOUSTON (INTERSTATE-10) AND MY CAR SUDDENLY STOPPED. I WAS ALMOST REAR-ENDED DUE TO THE CAR STOPPING SUDDENLY WITHOUT THE ABILITY TO ACCELERATE. THERE WAS ONLY A NARROW SHOULDER AND I HAD TO WAIT FOR THE TOW TRUCK. THE ISSUE IS THE INVERTER PUMP WHICH WAS A RECALL IN 2011 (12V536000) AND THE TOYOTA DEALERSHIP TOLD ME TO CALL TOYOTA US HQ. AFTER TWO WEEKS, MULTIPLE PHONE CALLS, AND ZERO FOLLOW THROUGH FROM TOYOTA, I AM STILL WITHOUT A FUNCTIONING CAR. THE TOTAL LACK OF CARE AND ACCOUNTABILITY FROM TOYOTA IS APPALLING AND FRANKLY RECKLESS. THIS IS A KNOWN ISSUE ON THE CAR AND I WANT TO MAKE SURE THIS DOES NOT HAPPEN TO SOMEONE ELSE. MY WIFE AND I ARE BLESSED THAT WE WERE ABLE TO WALK AWAY FROM THE STALL ON THE HIGHWAY UNSCATHED; HOWEVER, THIS CAN HAPPEN TO SOMEONE ELSE AT NIGHT AND PERHAPS THAT PERSON(S) WILL NOT BE SO LUCKY.”
