Electrical Equipment problems of the 2002 Kia Motor Sedona

I really need help and don?t know what to do. Also with my car my engine light was constantly on and to this day the light is probably still on and kia have not contacted me yet and even though I have a rental from enterprise through kia paying that is not the issue I want my car so that can sell it so that I don?t lose my home because I am unemployed due to this bucket of bolts. And also the kia repair man steve johnson at kirkland kia stated to me that my odometer reading was incorrect and the kia manufacturer took my car to another dealer because I wad being seen at their auto shop too much and is bizarre or what? I spoke to a paul stapleton at Kia Motors America because they have had my vehicle for 30 days straight. On oct 8 I picked my car up and 20 min later my engine light was back on. The day before I was offered $1000 for a good will gesture from kia. When the engine light came back on the next day mr. Stapleton offered to buy my vehicle back for 11,300 and that was without the $1000 good will. Today is oct 12th and by this afternoon I will be hearing from this company. This is not satisfying to me because I still had a full warranty on my car and for 11,300 I will have to purchase used and no warranty because I had a 2002 that was paid in full and a full warranty.
