I own Toyota rav 4 2008. I purchased a used certified vehicle in 2009. I have encountered an issue with my car such that engine started stalling intermittently while drive to my home. On the dash board I saw the engine oil light coming on intermittently. I was able to make it to home safely and upon inspection I found that engine oil level was way down to the point that it was not detectable at all. There was no oil on the dip stick. I looked at the service record and my car was serviced on oct 15th 2016 for oil change and other other safety recall. On October 15, 2016 the mileage was 83406. The next service was due on March 15 or at 88406 miles. I called the dch Toyota of simi valley dealership and they asked to come in the morning for inspection. Then I went to automotive store and purchased 5w-20 oil, it took 3 quart of oil and I was to see the oils level as normal on dip stick. Then I argued with dealer that it should not consume 3 or more quart of oil. I went to another independent mechanic he checked the tail pipe and he saw burned oil. He confirmed that engine is burning oil. Then I called Toyota motor and complained that engine is burning oil. They authorized the dealer to do the oils consumption test. They will investigate on how much oil it burns? dch Toyota of simi valley did the oil consumption study and reported that my car did not consume enough oils to do the warranty repair. They said it only consumed 3/4 quart of oil every 1200 miles and it passed the oil consumption test. Still I have the same car I put about 2 or more quart every 1500 miles. The engine repair will cost me $5000. 00 dollars or more. I think dealer did flawed study on oil consumption test do they do not have to do warranty repair.
