Told by Toyota that sludge in the engine is our fault despite regular oil changes. We don't have all our recepts but changed the oil at least 4 times since we owned the car. Impossible to believe that we were neglectful, especially when I am seeing so many other cases with the same thing happening. There needs to be an investigation here soon.
