Pulling out into traffic, without warning my car lost power and shut down! The car had to be towed to the dealership who advised that the engine had a catastrophic failure and needed to be replaced. I was told by the dealership that KIA would not cover the repair for two reasons: 1) I was beyond the warranty period (the car has 60,264 miles on it and apparently as the second owner I am only covered up to 60,000 miles not the 100,000 that comes with the car), and 2) despite acknowledging that they engine had a defect, KIA did not issue a recall to fix the problem. Instead, they issued a performance improvement notice. KIA also acknowledged via a phone call on 3/10/23 that they have mailed these notifications to the previous owner rather than to me. I have on a number of occasions conducted recall searches on www.nhtsa.gov/recalls which does not list the known engine defect! …

I was attempting to park in a parking spot that I use regularly at Dollar General. As it was coming to a stop, the brakes failed. I was pushing the brake pedal down. The car started to rev up and speed forward on it's own. It lunged forward jumping the curb and into the pillar. It wouldn't stop going forward. So I had to put it in reverse. As I did that, I put the brakes on as well as the ebrake. It was wanting to speed in reverse for a second. So I threw it into park and turned it off. My family and I went into the store to let the car settle down. Then we was able to drive it home and park it. So it's currently sittling in our driveway here at home.

Engine failed due to rod knock at 127,000 miles, this is a known defect with the car. Kia is refusing to replace the engine even though they know they are designed poorly and fail. Knock sensor and flashing engine light came on, had all the qualifications for the replacement but Kia is making excuses and denying it. I have all the paperwork and maintences done on time and they still won't cover it. My corroded brake lines were supposed to be fixed under the recall and they have had them on back order since September of 2022. Dealership has no loaner cars to provide.
