| Description of the problem | 1. Engine lights came on alerting us to a problem (check engine, service engine, etc.). After alleged repair, spouse drove to families house approximate 600 miles away and found a significant amount of oil had leaked from the system - oil had been changed as part of the fix. A second dealer, at the new location, "fixed" with the same hose again, with similar results, though my spouse only drop 120 miles. She is unable to continue the trip home due to this issue. 2. After taking to dealer, was told the vvt oil line was a known faulty part and needed replacement. Was not a "formal" recall, but was considered an internal recall to toyota that needed to be fixed for "free". Both dealerships claimed to have fixed the problem, though the engine is still leaking a significant amount of oil. There is a significant amount of data on the web that addresses this oil line and the associated issues. 3. Part was replaced, but with same type (part number, composition, etc.). Basically, a "new" bad part was replaced. Furthermore, the first dealership installed various gaskets and seals incorrectly, and still gave the car a safe rating for a 600 mile trip. The second dealership merely replaced a bad oil line with another bad oil line. |
