Auto Town Buick GMC

Terrible Experience — I bought a used car from this dealership back in May. A few days after I bought it my check engine light went on. I was told this was normal and that the problem will fix itself. This week, on my way to work, my check engine light went on again, and immediately my car started jerking and bucking. I called the service department and told them the issue and brought my car in. The said I needed two censors replaced (two of the most expensive sensors) and that it would cost me $800. I need my car for work and needed the issue to be fixed and quickly. My car was given back to me the next day and all seemed fine. The following morning I was driving to work and the same problem started, except worse. I called them and the said they would fix it right away. After getting my car back for the second time I noticed that it still didn't feel right. I brought my car back for a third time. They had the mechanic that had work on my car take it for a drive with me. He proceeded to explain why my car sounded and felt the way it did, but I was not convinced. Not five minutes after pulling out of the dealership my check engine light went on again. I decided to get it into a highly recommended mechanic right away. Thirty minutes into looking at my car the issue was clear... "Diag mil/poor running, test drive engine surging poor throttle response. Scan for codes found PO170 fuel trim problem bank 1 check engine data found front 02 sensor not switching at 0, long ft 27%, short ft 0. Check for VACUUM LEAKS OK, TEST EXHAUST FOUND FRONT AND REAR Catalytic Converter PLUGGED. RECOMMEND REPLACE Catalytic Converters AND 02 SENSORS REPLACED" Anyone who has a bit of knowledge about cars knows that this is not an issue that just happens one day. It happens overtime, and given the state these parts were in over a long period of time, which means, most likely the car was sold to me in this state. Not to mention the damage I have been doing to my car by driving it all these months. If I was informed of this earlier i would of been able to save a lot of money, and not damage other areas in my car. Also, there is a possibility that the two censors I had just spend $800 on them installing may not of been necessary. Unfortunately there is no way for me to find out know, which is very convenient. I am a young, hard, working, single women trying to make an honest living. Whether this mishap was intentional or out of pure incompetence I was taken for a ride. I received no apologies or answers as why this had happened. I am sickened by the treatment I received, and I wonder how they all can sleep at night.
