So my Soul is my baby; she has gone through 3 knock sensor problems in the past 3 months. Every time I take it to the dealership, they want to tell me nothing is wrong, it's passing all the tests, and no codes are popping up. I can hear knocking when I drive it. They also denied my claim to fix my engine. I know in my gut that something is wrong with something oil-related. I don't know if I need to pay them to look more into it, but even the dealership told me they are NOT confident that my car will make a 4-hour trip back home. Which, at that point im not sure why they would want me to take it off the lot. I don't know much about cars, and I'm a young girl. I don't know if they're trying to punk me right now, but it's just making me angrier. I know I have a 2.0L on my 2014. If anyone can give me any information or ammunition to help my situation, that would be amazing. I just need her to last a little bit longer. Thank you :)

So, my 2014 Kia Soul in March had to get the knock sensor fixed; it had a problem where it wouldn't accelerate, and the check engine light was blinking. I got it fixed at the dealership for free, and they gave me a whole diagnostic for free. They didn't alert me to anything major. The same thing happened today, is it the end of the car? Is this the dealership's fault? I'm kind of lost on what to do. I just want my car to be okay since I'm from an area where you kind of need one to do anything. Thank you!
