After having the car for about a week the engine light came on at that time I took the car back to Carmax Service Department in Canoga Park. They scanned the car and they told me that it was misfiring. Carmax fixed the car. They had the car for the ten days. The day I received the car back, the engine light came on again. Took the car to my mechanic and he ran the codes again and he told me it was misfiring, again. He cleared the code and I again returned the car to Carmax, and explained to them what happened. I checked on the car couple days later and I was told that they drove the car for 30 miles and the engine light didn’t come on. I picked up the car the next day On [XXX], the engine light came on, again. I returned the car back to Carmax, April 1st and talked to the Service Manager. I explained to him everything that happened. In each case, before returning the car or having the inspected, I did notice a difference in the way the car responded. Also, when I filled up with gas, the gas didn’t fill up all the way and there was a clicking sound when driving.
