2012 Toyota Highlander Engine Problems

Your oil pressure warning light came on at 112,500 miles, and when your mechanic inspected the engine, they found it had almost no oil left due to internal oil burning. Your mechanic determined that the piston rings have failed, causing oil to burn inside the engine rather than circulate properly. The engine is now burning about a quart of oil every 600 miles and may eventually produce smoke. Fixing this issue will require engine work to address or replace the failed piston rings.

The contact owns a 2012 Toyota Highlander. The contact stated while driving 60 MPH, the vehicle suddenly loss motive power while depressing the accelerator pedal. The contact pulled over and attempted to restart the vehicle; however, the vehicle failed to restart. There were several unknown warning lights illuminated. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that the timing chain fractured and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 120,000.

WELL BEFORE MY OIL CHANGES ARE DUE, MY VEHICLE NEEDS MORE OIL. THERE ARE NO APPARENT EXTERIOR LEAKS BUT THE OIL HAS TO BE LEAKING SOMEWHERE OR BURNING AWAY THROUGH THE EXHAUST.

WITH 1000 MILES LEFT ON AN OIL CHANGE OR SO OUR CAR WOULD RANDOMLY STALL WHEN YOU MAKE CERTAIN TURNS. OCCAISIOANLLY THE OIL LIGHT WOULD POP ONE WHEN IT WOULD STALL. I CHECKED THE DIPSTICK AND YOU COULD NOT SEE ANYTHING ON IT. I ADDED OIL AND TOOK IT INTO DEALER. THEY ARE DOING A CONSUMPTION TEST TO SEE HOW MUCH WE LOSE IN 1000 MILES. THIS VEHICLE ONLY HAS 86,000 MILES ON IT. WE HAVE NO LEAKS AND NO VISIBLE SMOKE COMING OUT OF EXHAUST. THIS HAS ME WORRIED OF SIMILIAR PROBLEMS THEY HAD WITH ONE OF THERE OTHER 4CYL ENGINES.

I WAS DRIVING ON A HIGHWAY I HEARD A NOISE AND SMOKE STARTED COMING FROM UNDER THE HOOD I PULLED OVER AND LOOKED UNDER THE HOOD AND SAW SMOKR A TOW TRUCK DRIVER WHO HAPPENED TO BE PASSING BY PULLED OVER AND SURE FIRE UNDER THE HOOD HE PUT THE FIRE OUT WITH A FIRE EXTINGUISHER I CALLED NINE-ONE-ONE FOUR FIRE TRUCKS TO MAKE SURE THE FIRE WAS COMPLETELY EXTINGUISHED MY MECHANIC SAYS A ROD POPPED AND PUNCTURED THE OIL TANK WHICH CAUSED ALL THE OIL TO LEAK OUT ONTO THE SIDE OF THE HIGHWAY THE FIREMEN ACTUALLY SPREAD SAND OVER IT MY INSURANCE COMPANY HE'S REFUSING TO REPAIR THE CAR BECAUSE THEY SAY THERE WAS A MAINTENANCE ISSUE BECAUSE THERE WAS NO OIL IN THE CAR WHEN THEY LOOKED AT IT THERE WAS NO OIL IN THE CAR BECAUSE IT ALL LEAKED OUT ON THE SIDE OF THE ROAD I HAD JUST PUT OIL IN THE CAR THE PREVIOUS DAY THIS HAPPENED ON NOVEMBER 26TH 20186

THE "MAINTENANCE REQUIRED " LIGHT CAME ON AND I STARTED NOTICING A STRANGE NOISE AS I STARTED THE CAR EVERY MORNING AND AGAIN AS I ACCELERATED. I CALLED AND MADE AN APPOINTMENT WITH THE DEALER I PURCHASED THE VEHICLE. THE SERVICE ATTENDANT REPORTED TO ME THAT THE OIL LEVEL WAS BARELY VISIBLE ON THE DIP STICK. THE DEALER SHIP CONDUCTED AN "OIL PRESSURE TEST" AND DID NOT DISCOVER ANY LEAKS. SO THEY ARE CONDUCTING AN "OIL CONSUMPTION" TEST AND I AM TO RETURN TO THE DEALERSHIP AFTER 1100 MILE TO DETERMINE THE AMOUNT OF OIL CONSUMED ON MY VEHICLE.

VEHICLE GOT STUCK IN SHALLOW WET SAND, WITHIN LESS THAN A COUPLE MINS OF ATTEMPTS TO MOVE FORWARD AND BACKWARD BY SPINNING WHEELS , THE CAR STARTED SMOKING AND BECAME FULLY ENGULFED IN FLAMES. IT WAS A TOTAL LOSS. THE ISSUE IS THE LITTLE THAT IT TOOK TO START A FIRE LIKE THIS - PERHAPS SOME COMPONENT NEEDS TO HAVE SAFETY FEATURE ADDED OR STERN WARNING COMMUNICATED AND POSTED IN THE CAR OF THIS DANGER. WE LEARNED THAT LESSON THE VERY HARD WAY. INTERNET SEARCHES AFTER THE FACT SHOW OCCURRENCES OF THIS SAME SCENARIO ON ICE, ETC ON MODERN CARS. *TR

MY HIGHLANDER WAS AT THE AIRPORT FOR THREE DAYS PARKED. WHEN I WAS LEAVING THE LOT I WAS DRIVING SLOW IN THE LOT TO PAY MY PARKING. WHEN I GOT OUT OF THE LOT TO MAIN STREAM TRAFFIC I TRIED TO ACCELERATE AND THE CAR WOULD ONLY GO SLOW AS I KEPT PUSHING THE THROTTLE. THERE WERE CARS ON BOTH SIDES OF ME WITH NO ONE IN FRONT AND THEN THE CAR JUST TOOK OFF. IT DID STARTLE ME BECAUSE I WAS NOT EXPECTING THIS. THANK GOD NO ONE WAS IN FRONT OF ME BECAUSE I AM SURE I WOULD NOT HAVE REACTED FAST ENOUGH TO STOP BECAUSE OF THE RAPID ACCELERATION. SOMETHING IS WRONG WITH THE THROTTLE IN THESE VEHICLES. I DID NOT TAKE IT IN BECAUSE I AM SURE THEY WOULD NOT HAVE BEEN ABLE TO REPRODUCE THE PROBLEM. THIS HAS ONLY HAPPEN ONCE AND I HOPE IT DOESN'T HAPPEN AGAIN. *TR

OCCASIONALLY, AFTER COMING TO A STOP, AND THEN TAKING OFF AND TURNING EITHER RIGHT OR LEFT, THE ENGINE WILL LOSE POWER FOR A FEW SECONDS. THE ENGINE DOES NOT SHUT OFF, IT JUST SLOWS DOWN TO JUST ABOVE IDLE SPEED FOR 3 OR 4 SECONDS AND THEN RESUMES NORMAL ACCELERATION OPERATION. *TR
