Vehicle was accelerating on highway when knocking was heard and engine failire occurred. was coasted to a stop and oil was checked. no oil in the vehicle. new engine needed for vehicle. vehicle is at 80,000 and oil changes were maintained. no oil leaks visible.
Excessive oil consumption leading to motor loss. this seems to be a known issue for vehicles that are regularly maintained and scheduled oil changes every 3-5,000 miles. it seems it should be handled as a recall by toyota if this many vehicles are having the same issue. excessive oil consumption began around 90k miles. at 148k, vehicle was requiring more oil than i was able to put in. engine began "knocking", and even after topping off oil, within 48 hours experienced complete motor loss. knocking seemed to be worse when idle. luckily, i was able to make it through a couple stop lights and make it to a safe place before engine stalled completely.
Engine is burning at least 1 quart of oil per week and estimated driving miles per week is between 200 miles to 300 miles. there is no major oil leaks anywhere that i can see and there is no oil on the floor where the car is parked.
