Engine Belts And Pulleys problems of the 2004 GMC Envoy

I traded my 2005 Ford focus 26410 miles to wade raulerson GMC on October 3, 2007 wrote two checks in the amount of 500. 00 each that they held for four weeks for a down payment. We looked at a 2004 GMC Envoy with 65,000 miles the salesman quoted us a price of 17,000 so we did the paper work the first time on the 16th we were called in again and told we had to sign more documents this time the price of the Envoy rose to 21698. 35, I asked about my 05 focus was told it sold the next day and we had to have gap protection. Payoff on my car was 12,502. 95 and it looked as if they were giving me 14900. 00 but raised the price of the truck by 4000. 00. Bad deal to begin with. The problems began. I had to return it at the end of the month in October 2007 to have the headlights, seatbelt, and motor in the window replaced, and diagnosed to find why the service engine light will not go out. Two weeks later stranded at the daycare I had to buy a new battery. On 05/05/2008 the conditioner went out. I paid the dealership over 100. 00 to tell me it would be an additional 600. 00 plus dollars to repair the mode actuator door motor. October 17, 2008 I spent 375. 02 to have both the shift control cable and gear shift lever removed and replaced. Thank god I was actually on a parking lot when the cable broke and not in traffic. Contacting wade raulerson GMC has been useless I have practically been told you bought the "lemon" as-is now it's your troubles! there should be a law against this type of business and not just for new cars. Now no-one will touch it because of the problems it is having and the large amount that's now owed. Every time the VIN is pulled I get pushed out of the door faster than I can blink. Btw the service engine light is still on and has been since I left the dealership. I?m tired of honest hard-working people being raked over the coals by unscrupulous dealers while they get protected by the "as-is" rule then laugh all the way to the bank.
