I bought a 01 ford taurus 1/15/11. The terms of me buying the car was that the dealer gave me a 30-day warranty on trans/engine, and in addition to that, the check engine light would be fixed. Yes I know, I shouldn't have even went near the vehicle b/c the light was on, but I did, LESSON LEARNED. So in other words, I spotted a defect, and the guy who sold me the car agreed in writing to fix the defect as part of the sale. Now ever since I bought the car, it has broken down on me twice and overheated numerous times. I went and had the light tested and the codes that came from that are: p0420, p0430, p0171, and p0174. I've taken the car up to the lot multiple times for them to fix "other things", instead of fixing the real problem. This is a very long story and I'm not gonna put you all through that. If interested, please take a look at my attachments. I've attached a doc called my complaint, which is what I sent to the BBB and Attorney General. And there's another doc called documentation, which is everything that's been going on b/w me and the dealer. I've tried to document everything possible. If anyone can offer any advice whatsoever, please let me know what you think I should do next. Thanks for reading!
