2012 Toyota Prius Engine Problems

The contact owns a 2012 Toyota Prius V. The contact stated while driving at an undisclosed speed, the temperature gauge and check engine warning lights illuminated. The vehicle then stalled. The vehicle was able to be restarted. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 190,000.

I was driving on the internet doing 60mph and there was a very loud bang and then a shaking of the parts under the hood. I was right next to an exit and coasted off the exit to a hotel parking lot. I had car towed to my mechanic. He said that the piston went thru the engine and the engine is done and needs replaced. I am having a hard time trusting Toyota again to purchase another Prius. I have had Prius for over 10 years and never had anything like this occur. I had no warning signs and no dashboard lights lit up until after all of this occurred and scared the life out of me then the engine light came on.

The contact owns a 2012 Toyota Prius. The contact stated that when the vehicle was started, there was a rattling sound coming from the vehicle. The contact stated that while depressing the accelerator pedal, the vehicle started shaking abnormally with a rattling sound. The vehicle was taken to the dealer where it was diagnosed with a blown head gasket and that the engine block needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 106,000.

There is no incident occurring to me .but I change some parts like head light.& whisper .engine .

Head gasket failure

the car was serviced regularly and for unknown reason the engine started running rough. I took it the mechanic and after completing a diagnostic test he said i have a blown had gasket in the engine. After reading online about the issue i discovered this year and model of toyota are notorious for having a blown head gasket issue. My mechanic recommended the engine be replaced. This is an expensive repair and toyota is denying any accountability about the issue

I am having issues with my Toyota I was never contacted NHTSA CAMPAIGN ID: 18V684000. My car has failed numerous times.

Had blown gasket repair last year (which was fixed by my local Toyota Dealership and all cost paid for by myself). Dealership acknowledged that there were known issues with failures due to clogged EGR's and out-dated manifolds. Was never recalled and did not know about the issue until after the incident. Wanted to report issues since it appears countless other have been in the same situation with gen 3 Prius. Toyota needs to be offering EGR cleanings and updated manifolds at no cost and reimbursing customer's for previous repairs.

Head gasket blow up at 175000 miles

MY TOYOTA PRIUS V ONLY HAS 121,153 MILES ON IT AND DURING A SHORT DRIVE TO WORK WHERE WE NEVER REACHED SPEEDS OVER 50MPHS OUR PRIUS V OVERHEATED CAUSING A BLOWN HEAD GASKET AND ALL SORTS OF COMBUSTION ISSUES. THE REPAIRS WERE $3000. THIS IS A 2ND FAMILY CAR WHICH HAS ALWAYS BEEN MAINTAINED BY EXPERT, LICENSE AUTO MECHANICS. THIS SHOULD NEVER HAPPEN ON A CAR WITH SUCH LOW MILAGE! I HAVE LEARNED THAT THIS IS A COMMON ISSUES WITH THIS TOYOTA PRIUS MODEL AND TOYOTA SHOULD FILE A RECALL AND FIX THE OVERHEATING ISSUES.

THIS VEHICLE HAS BEEN BURNING OIL FOR THE PAST 10,000 MILES. VEHICLE HAS HAD ALL SERVICES AND SYNTHETIC OIL CHANGES DONE FROM DAY 1 AT THE DEALERSHIP. OIL CHANGES EVERY 5,000 MILES SINCE DAY 1. AT 90,000 MILES THE CAR STARTED BURNING OIL EXCESSIVELY. COMPLAINTS AND DIAGNOSTICS WERE ATTEMPTED AT TOYOTA FRANCHISE DEALERSHIPS BUT THEY FAILED TO FIND THE ISSUE. FINALLY AT 100,000 MILES THE ENGINE FAILED DUE TO HEAD GASKET FAILURE. THIS VEHICLE IS CLASSIFIED AS A PARTIAL ZERO EMISSION VEHICLE AND IT IS REGISTERED IN A STATE THAT FOLLOWS CALIFORNIA AIR RESOURCE BOARD REGULATIONS AND IS BEING SERVICED IN A STATE THAT FOLLOWS AS WELL. UNDER THE PZEV REGULATIONS, TOYOTA WARRANTIES EMISSION RELATED COMPONENTS FOR 15 YEARS OR 150,000 MILES. UNDER TOYOTAS WARRANTY GUIDE IT STATES SEALS AND GASKETS ARE COVERED. THE MANUAL DOES NOT CLARIFY ANY FURTHER LEAVING THE COVERAGE LEVEL VAGUE AND QUESTIONABLE. UPON TRYING TO GET TOYOTA TO REPLACE THE ENGINE, THEY GAVE US A WEEK OF NO RESPONSES AND FINALLY DECLINING THE CLAIM EVEN WHEN THE MANUAL STATES IT SHOULD BE COVERED. THE OIL BURNING ISSUE WITH THIS MOTOR IS A BIG PROBLEM THAT TOYOTA HAS BEEN TRYING TO COVER UP. TOYOTA IS QUOTING $13,000 FOR ENGINE REPLACEMENT. THEY HAVE A SERVICE BULLETING REGARDING THE OIL BURNING BECAUSE IT'S A KNOWN ISSUE, BUT THEY ONLY HONOR CLAIMS UNDER THE 5 YEAR 60,000 MILES POWER TRAIN WARRANTY.

WHEN IDLING THERE IS A LOUD RATTLE AND MULTIPLE RANDOM MISFIRES IN THE ENGINE. APPEARS TO BE A HEAD GASKET LEAK PROBLEM FROM READING FORUMS. I HAVE BEEN TO MULTIPLE REPAIR SHOPS THEY CANNOT DETERMINE THE PROBLEM.

IT IS HAVING HEAVY MISS FIRE WHICH MAKE THE ENGING SHAKING TOO MUCH MANY TIMES

AT ABOUT 100,000 MILES THE ENGINE BEGAN USING (BURNING) OIL AT THE RATE OF ABOUT 1 QUART EVERY 1000 MILES. NOW AT 150,000 MILES THE OIL USAGE IS 1 QUART PER 500 MILES. THE OIL HAS BEEN CHANGED USING THE RECOMMENDED LUBRICANT MORE OFTEN THAN REQUIRED SINCE THE CAR WAS NEW. TOYOTA IS AWARE OF THE PROBLEM AND HAS REDESIGNED THE PISTONS AND RINGS BUT BUT OFFERS NO FINANCIAL HELP FOR CARS OFF WARRANTY. THE DEALER ESTIMATED REPAIR COST IS OVER $5000.

APPROXIMATELY 2 MONTHS AGO I STARTED HAVING PROBLEMS WHEN STARTING THE CAR IN THE MORNINGS OR AFTER THE VEHICLE SAT FOR A WHILE. WHEN STARTING THE VEHICLE IT WOULD SHAKE AND RUN ROUGH BUT WOULD RUN GOOD AFTER IT WARMED UP. I TOOK IT TO MY LOCAL TOYOTA DEALER AND A MANIFOLD AND A SENSOR WAS ORDERED BY THE DEALER. THE NEXT DAY I WENT BACK TO THE DEALER TO HAVE THE PARTS INSTALLED. I SAT IN THE WAITING AREA FOR OVER 2 HOURS ONLY TO BE TOLD IT WAS NOT THE MANIFOLD AND SENSOR. AFTER A SCOPE WAS USED TO DIAGNOSE THE PROBLEM. THIS TIME I WAS TOLD I EITHER HAD A LEAKING GASKET OR A CRACKED ENGINE HEAD. THIS PRIUS V ONLY HAS 94245 MILES ON THE ENGINE. IT HAS ALWAYS HAD REGULAR MAINTENANCE AT THE TOYOTA DEALER. THE DEALERSHIP QUOTED ME TO REPLACE THE ENGINE AT $6000.00. I HAVE NEVER HAD A VEHICLE WITH LESS THAN 100,000 MILES USAGE TO NEED A NEW REBUILT ENGINE ESPECIALLY A TOYOTA PRODUCT. I AM VERY DISAPPOINTED IN TOYOTA. THIS WAS A KNOWN CONCERN ON TOYOTA'S PART AND IT WAS NOT PROPERLY ADDRESSED IN A RECALL, NOW I AM LEFT HOLDING A VERY EXPENSIVE BAG. HOW MANY OTHER UNSUSPECTING,CUSTOMERS WILL YOU LOSE BESIDES ME

2012 TOYOTA PRIUS II, DEALER MAINTAINED, NOW NEEDS NEW ENGINE DUE TO BLOWN HEAD GASKET. MILEAGE 151000. THE CAR HAS RUN PERFECTLY UNTIL A RECENT ENGINE LIGHT CAME ON. WHEN IT WAS BROUGHT INTO THE DEALERSHIP, THE DIAGNOSIS WAS MISFIRING OF 2 CYLINDERS AND COOLANT LEAKING INTO CYLINDERS 3 AND 4. THERE WAS NO PREVIOUS ENGINE PROBLEMS. AN OFFICIAL COMPLAINT WAS FILED WITH TOYOTA CUSTOMER SERVICE. THEY RESPONDED THAT THERE WAS NO FAULT ON THEIR END AND I SHOULD HAVE THE ENGINE REPLACED AT AN AUTHORIZED TOYOTA DEALER. A SEARCH FOR THIS TROUBLE RESULTED IN SEVERAL OTHER COMPLAINTS OF THE FAILURE OF HEAD GASKETS IN THIS YEAR AND MODEL PRIUS.

FAULTY HEAD GASKET, ENGINE SHAKING ON STARTUP, COOLANT DRAINING PREMATURELY, WHITE EXHAUST, LOW COMPRESSION AND POWER.

IT STARTED WITH SHAKING ON STARTUP, IDLE AND LOW SPEEDS. CHECK ENGINE LIGHT CAME ON. DIAGNOSED WITH MULTIPLE CYLINDER MISFIRE. IGNITION COILS REPLACED, BUT DID NOT SOLVE THE PROBLEM. SUBSEQUENT ANALYSIS INDICATED COOLANT IN THE COMBUSTION CHAMBER DUE TO A FAILED HEAD GASKET.

VEHICLE HAS BEEN CONSUMING OIL TO THE POINT WHERE THE VEHICLE NEEDS MONTHLY OIL CHANGES. WAS TOLD MANY TOYOTA PRIUS MODELS HAVE HAD AN OIL CONSUMPTION ISSUE AND THAT I SHOULD FILE A COMPLAINT.

THE ENGINE WENT STALLED IN THE MIDDLE OF THE HIGHWAY. LUCKY ENOUGH, I WAS ABLE TO STOP THE CAR SAFELY WITHOUT ANY COLLUSION. BROUGHT THE VEHICLE TO A MECHANIC AND DIAGNOSED WITH EXCESSIVE CONSUMPTION OF ENGINE OIL. THE ENGINE HAD CATASTROPHIC DAMAGE AND NEEDED A REPLACEMENT. I SPOKE TO PIERCEY TOYOTA SERVICE DIRECTOR KEN JOHNSON AND HE STATED THERE IS NO ACTIVE RECALL FOR THE VEHICLE AND DO NOT BELIEVE IT IS THE VEHICLE ISSUE. I DO NOT BELIEVE THAT IS THE CASE, FURTHER INVESTIGATION IS NEEDED TO PREVENT OTHER SAME MODEL DRIVERS FROM A DEADLY ENGINE STALLING CRASH.
