If you are driving one of these vehicles, you need to contact your Toyota dealership immediately! Request that they complete an oil consumption test. There is a safety issue that could potentially lock your engine. They have not issued a recall but sent a Technical Service Bulletin to dealerships stating that this is a serious issue but only to fix it if the customer initiates the issue. My car currently burns 2 quarts of oil in a 3 week period. It also failed both oil consumption tests. However, because the mileage on my vehicle exceeds 150,000 miles, THEY WILL NOT FIX IT! Don't find yourself in this position.
