My kia was making a whistling noise on and off for awhile then my oil light would flicker so I figured I need an oil change. Got my oil changed and then the car started make a knocking noise and would get worse with acceleration and would have a hard time accelerating. It would jolt and vibrate and make knocking and flapping noises. Turn on my road to go home and lost power. My car slowly came to a stop I could not accelerate at all. My engine, battery, oil, and eps light came on. I tried starting it up and would come on for about 5 seconds make a lot of noise and the engine would turn off but my radio and windows still worked. My ac was on but not cooling. All the cabin lights work still but my brake are stiff.
I was told by the kia dealership that my 2011 kia Optima needs a new engine. I was driving down the highway in middle lane. I tried to accelerate my car and my engine was making a rattling noise and the oil light started flickering all the lights on the dash came on and the car stalled. I had to call a tow company to tow my car to kia. The next day kia said I needed a new engine and I must prove that I kept maintenance on my car by providing them with all my oil change receipts. I have no car now and I need to get to work and get my kids to school.
