Engine made knocking noise while on the freeway, and then the car died - everything quit. Had to coast off the nearest exit. There was no warning - no maintenance required lights were lit on the dash. Still had another almost 2,000 miles to go before next oil change was due. Engine is dead. Per Toyota "catastrophic internal damage from the rods. " car was well taken care of, never missed an oil change, and 8 of the last 9 years, the car was loyally serviced at a Toyota dealership.
Driving car and the oil light failed to indicate oil was very low. Heard a knocking noise so I checked the oil and discovered the oil was low although oil had just been added a few days earlier. I was not sure if the vechicle was fit to drive, so for safety reasons I had the car towed to my mechanic. The mechanic checked out the car and said the engine was damaged due to the lack of oil and constant burning of oil due to a defect in the Toyota rav 4 engine/oil system which causes the oil to combuse and burn off preventing the oil indicator light to alert the driver to add oil. This defect causes engines to seize. At this time I called Toyota of north America (1800 331-4331) directly to report this issue. I was told that as of today no recall or reimbursement is being issued but if everyone with this problem call Toyota of north America directly to report their problem then an investigation will be issued. So please call today so we may all be reimbursed from Toyota for this issue that they are well aware of and are choosing to do nothing for the consumers. They will then give you a case # that they tell you to keep just in case a recall is activated.
My wife was driving home from work and the engine started to lose power, and making a loud knocking noise. After arriving home, I started the engine and heard the same loud knocking noise. I checked the oil level, and saw that it was non-existent. After researching on the internet, I found many people with the same issue. It appears that the oil line is continuing to fail on the newer v-6 engines. I will be calling Toyota tomorrow. The car is a 2006 Toyota Rav4 sport 4wd v-6. It has 53,000 miles on it. Toyota performs regular oil changes.
