keyes toyota Deceptive practices at dealer service center van nuys, California

The keyes toyota service department neglected to inform me of a technical service bulletin put out by toyota about the engine oil consumption issue I was having when I first went in to have the problem checked. The TSB (0094-11)has already been out a few months before I went in with the stated problem.  When I expressed concern about the loss of engine oil, my concerns were not taken seriously. My car was still under warranty when I first noticed the problem with the oil loss. I went to the dealer numerous time since then for regular maintenance and kept expressing my concern about the oil loss. I was told that it was normal for engines to consume a little oil and to keep an eye on the oil level. They generally told me that it was not a big deal and that it was normal. Not once did they let me know there was a TSB out for the very same problem I was experiencing. Nor did they tell me that I could have had an engine oil loss consumption test done to document the oil loss. The last time I went in to the dealer was on 8/28/12 to complain about low oil and to have the oil change done. That was when I was told that I had this option to have the test done to document the oil loss but was told by the adviser that "it would be of no use to me since I was out of warranty."
When I insisted to have the test done anyways, the adviser told me that he was just trying to save me some money by not doing the test that was useless anyways. I got the test done with the intervention of the assistant service manager only after I called toyota to complain about what was going on with the service department. After a 1000 miles went back to the dealer  to have them check the levels and it confirmed that my car was consuming oil above acceptable levels.  The dealer wanted approx. $6000 to fix the problem which would have been covered under the powertrain warranty. The dealer said that since my car is already out of warranty, the repair would have to be out of my own pocket.

    In summary,  The powertrain warranty was for 5 years or 60,000 miles. I first brought in my car for the oil loss issue  when it had 57,235 on the odometer. The car had 69,374 miles when I was told that the oil loss could be documented. I found out about the TSB on my own after doing my own research. I have come to believe that the dealer deliberately withheld facts from me about the oil loss knowing that my warranty was about to expire. They lied and distorted facts when I asked about why my car was losing oil. The advisers that I've dealt with were very evasive and I felt like they were not telling me everything. They tried to blame me for my car losing oil because I was not maintaining it regularly. After I told them that I can show proof that I did regular maintenance on my car, they implied that the place  where I usually go to for maintenance(firestone) was incompetent. As a result of the dealer's deceptive practices, toyota refuses to even consider my complaint and the dealer refuses to do anything for me because the car is out of warranty. The dealer's official position is that unless toyota authorizes the repair, they can't do anything more. I am fed up with the way I was manipulated into thinking that there was nothing wrong with my car when they knew that there was. The facts prove it. And I am hoping that this complaint will be read by people who can do something about this problem.
