The windows will NOT stay up, front passenger window has come completely loose from its track and has fallen down in such away, that it slams against the inside door panel, the only part of the window you can see is the triangle shaped edge that would normally fit in the corner of the window. I'm [XXX], with kids and this is my only transportation. Winter is here and the only window that stays up is the drivers side, and it's about to go too, it wobbles when rolling it up or down. My dad was a mechanic all his life, but he's [XXX]. I use to help him work on cars every day.. I have a torn rotator cuff from turning my now deceased husband in the month long hospital stay, been with him since I was 17, I'm now [XXX] , and can not do a lot of things I once did.. I do NOT have the money to fix this car as my husband died 2 months ago being flown in a helicopter twice to the hospital, is more expensive than ANY vehicle around here costs, i cant work due to my torn rotator cuff. No one in their right mind would buy my car with the windows.. I've done some research and my Kia optima is just one of thousands with this same issue. The only option I have is to walk the 5 miles into town to get what me and what's left of my family's essentials. I've never had a Kia before, and I'll never get another one. My car also burns oil, I know this because I was raised to know how to check to see if it's burning oil, I took it into dardanelle tire and auto, I know the lead mechanic. I was informed that in fact it was burning oil, and I knew that meant I would have to be checking the oil every other day. The exhaust pipe has SO much black burnt oil all over the entire end of the pipe.. check engine light came on 2 weeks after I bought it, something about the catalyst. The small dealership owner told me everything was perfect on this car, he lied, they have ways of turning the check engine light off, I've seen my dad do it. I think it's time for a recall already.
