What owners say about the engine

Verbatim from NHTSA complaints, newest first
“The contact owned a 2008 Toyota Highlander. The contact stated that while driving at approximately 20 MPH, an abnormal, booming sound was emitted from the vehicle as heavy, black smoke entered her vehicle. Due to the smoke, the contact's vision became obstructed, and the contact immediately shifted into park and jumped out of her vehicle for safety. It was unknown if there were any warning lights. As a result, the contact injured her right hip and strained her vocal cords. The vehicle quickly became engulfed in flames as authorities were called to the scene. The fire department extinguished the flames as both a fire and a police report were filed. The vehicle was towed to an independent mechanic, where it was deemed a total loss. There was no property damage. The origin of the fire was unknown, and an investigation was opened by the insurance company. The contact sought medical attention the next day and was treated for the strain on her right hip. The manufacturer was notified of the failure, and the contact was given a case number. The contact was also informed that she would receive a response from them within 45 days. The vehicle was destroyed. The failure…”

“The engine burns Coolant and yet doesn't overheat. The engine on cyl 4 misfires. Changing the head gasket didn't repair the issue, replacing all fuel Injectors and ignition parts didn't either. Heads inspected and passed. Compression testing passed. Always misfires on cyl 4. No repair aside from an ecu reflash or replacement seems to be possible. 4 shops looks at it and couldn't find any reason why it was misfiring and no traces of water were found in the interior, on the floor, in the oil or exhaust in the cooling system.”

“On January 19, 2021, after driving for about two hours, I suddenly started to hear an unusual knocking noise from the engine. I slowed down, but I was unable to pull over immediately because I was driving on a very dark two lane highway, with no safe shoulder. After the same noise continued for about five to ten minutes, a light began to flash indicating extremely low oil pressure, and warning that the car should stop immediately. At that point, fortunately, I was able to pull over at a gas station, where I discovered that oil was gushing from my engine onto the ground. I checked my oil dipstick and noted that the car had no oil, and was thus inoperable. I was extremely concerned that the engine had been damaged while being driven with little to no oil. In 2014, Toyota issued a notice of a Warranty Enhancement Program – ZE2, related to extending warranty coverage for repairs related to a leaking or seeping engine oil cooler pipe. I never received any owner notification of this issue in 2014. Toyota refused to pay for the repair in 2021, and now in November 2021, the engine has quit due to the damage incurred in January 2021. The engine oil cooler pipe is…”

“On September 25, 2021, my husband was driving our 2008 Highlander locally to the store. The low pressure light came on and said pull over immediately. He pulled over and and checked the oil dip stick and our car was totally out of oil. He also notice oil under our car and a line of oil going up the street. The following day, I contacted Toyota Experience Center and was informed their were no service campaigns on my Highlander. I had the car towed to my local mechanic and he verified that the car had no oil and replaced the failed oil cooler hose. My concern is that the oil cooler hose failed, draining all of the oil in minutes. I feel this is a safety issue because of how rapidly it occurred and If we couldn't immediately stop the car our engine could have seized up and made the car stop.”

“I WAS DRIVING MY VEHICLE ON A SHORT TRIP ON THE HIGHWAY WITH MY EIGHT YEAR OLD DAUGHTER WHEN A HOSE ON THE ENGINE OIL COOLING ASSEMBLY BURST. THIS RESULTED IN ALL OF THE OIL IN THE VEHICLE BEING DRAINED IN A VERY SHORT AMOUNT OF TIME. NO WARNING LIGHT CAME ON AS A RESULT OF THIS. I DIDN'T DISCOVER THE ISSUE UNTIL PULLING BACK INTO MY DRIVEWAY IN WHICH THERE IS AN INCLINE. THEN THE LIGHT INDICATING LOW OIL PRESSURE FINALLY CAME ON. I OPENED THE HOOD AND FOUND THE DIPSTICK TO BE COMPLETELY DRY. I ALSO FOUND A SLOW DRIP OF OIL UNDER THE CAR (ONLY SLOW SINCE IT WAS ONLY A SMALL AMOUNT OF OIL REMAINING). I THEN DISCOVERED THAT THE ENTIRE UNDERCARRIAGE OF THE VEHICLE AS WELL AS THE BACK HATCH OF THE VEHICLE WERE COVERED WITH OIL. MY DAUGHTER AND I ARE VERY FORTUNATE THAT THE OIL THAT COVERED THE VEHICLE DID NOT CATCH FIRE AND AS FAR AS I KNOW THE OIL SLICK ON THE HIGHWAY DID NOT CAUSE ANY ACCIDENTS. I AM NOW BEING TOLD BY TOYOTA THAT THIS IS A KNOWN ISSUE, BUT IT IS NOT LISTED AS A RECALL. NOT ONLY DID THEIR KNOWN ENGINEERING ISSUE PUT MY FAMILY AND OTHER FAMILIES' LIVES IN DANGER, THEY ARE ALSO NOT WILLING TO PAY FOR THE REPAIRS OF THE DAMAGE TO THE VEHICLE THAT…”

“WHILE DRIVING ON I40 NEAR TEXAS/NM STATE LINE, OIL COOLER LINE FAILED RESULTING IN THE HIGHLANDER DUMPING OIL ON THE ROADWAY FOR OVER A MILE BEFORE IT WAS NOTICED. PULLED OFF IMMEDIATELY, SAW OIL POURING OUT FROM BOTTOM PASSENGER SIDE OF ENGINE COVER. EXTERIOR LOWER PASSENGER SIDE AND REAR OF VEHICLE WERE ALSO COVERED IN OIL. NO DASH INDICATOR LIGHTS EVER WARNED OF ISSUE. THIS LEFT US STRANDED ON SIDE OF BUSY INTERSTATE WITH HEAVY SEMI TRAFFIC FOR HOURS WHILE WAITING FOR A TOW TO A SHOP FOR REPAIRS, WHERE WE HAD TO WAIT A DAY FOR THE PART. COMPLETELY UNACCEPTABLE TOYOTA KNEW OF A DEFECTIVE DESIGN THAT COULD LEAD TO ACCIDENTS AND DEATH, AND CHOSE NOT TO ISSUE A RECALL! WILL BE SEEKING LEGAL ACTION.”
