NHTSA Complaint #11577331 — 2009 KIA BORREGO

I absolutely love my kia borrego and have been trying to find a way to give the car back and end payments on it because I can't afford to put parts on it anymore. I'm on disability and can't seem to find the real issue after thousands of dollars in failed attempts. My transmission has not been shifting and if it does shift, it's sudden and aggressive. It will rev up higher than normal and if you continue holding the gas at all it will jerk you as you are driving. It has nearly caused me to swerve or be hit by anyone following. It feels like someone hits the car from behind very hard. Not only is it scary, it is aggressive and could cause whiplash or harm to my children. On 3 occasions I have been driving and my seat belt has randomly popped off on the driver seat and twice in the passenger seat. It's awful I have to plan where I will park or my route because my car randomly shuts off while driving which is dangerous on the curvy roads where I live and the car mostly doesn't shift at all while driving after all the money I've wasted trying to have it fixed. This car was the best thing that I have ever owned until it became a dangerous, unreliable nightmare.
