Check engine light came on after driving the car about 472 miles. Called dealer repair, which instated that it was just the gas cap loose, which he had us remove and retighten. We were advised to keep driving it and that the check engine light would eventually go out. We drove it for a few more days and then had two different local mechanics shops check the code on the check engine light. Both said that the engine was misfiring, either random misfire, or misfire on cylinders 3 and 4. We called the dealer again, who said that the mechanics didn't know what they were doing and were wrong, but that we should bring the car in next week. We brought the car in on 8/30/11, with about 872 miles now on it and the check engine light still on. The dealer checked the car and said the some cam shaft adjusters were not set properly at the factory and that they would have to add a shim kit to correct this! (on a new car!) the next day, car still didn't work, they had to called Subaru manufacturer and tried at least 5 other procedures and car still doesn't work. The car is defective and should not have been sold as a new car. They have had the cover over 10 days now and still not fixed. We just want a new car, and get out of that one. Please help.
