At about 125k miles, my Prius nearly ran out of oil between services, and I religiously service my vehicle. I burned 1 to 2 quarts between services since. At 272,408 miles, I just paid $5751. 59 for a complete engine rebuild. . . Rest of car is in great shape. Oil consumption problems were known by the dealerships, but I was given no recourse except dealing with it. Latest issue. . Check engine light on, misfire on cylinders 1 and 4 (progressing to all), horrific knocking noise with sound of rushing water upon start-up. Eventually, (once the cylinders fired significantly) the engine could run satisfactorily for the remainder of the drive. . . Until the next start. Early on I read that Toyota knew of the under-engineered motor of the 2010s, but I have not received anything announcing a recall or care to fix their engineering issue. I have my service records to validate the care I've given to my car. The date of the engine rebuild is what I will provide as to when this happened, but the oil consumption began years ago.

Upon starting vehicle, a very loud knocking noise, accompanied by shaking occurred. At this time no failure/warning lights appeared on dashboard. Moved car forward approximately 15 feet, and placed car in park, knocking/shaking did not abate. Turned car off. The next day, the car, upon starting had the same loud knocking/shaking. It was audible from several feet away from the car. On the second time, it was accompanied by a warning light to put the car in park. Vehicle was towed to the dealership.
