NHTSA Complaint #11617124 — 2021 KIA K5

While driving on my way home from work my , brakes became extremely hard to press down on and then my service engine light came on this all occurred on 7/31/2024. So the very next day I took my vehicle to a Kia dealership which was 8/1/ 2024 to find out what was causing this to happen. The technician stated that they would have to put it on a machine and run a diagnostic on it. I asked the technician while they were doing that to change the oil. I also realized that the oil light for my vehicle has NEVER came on since I purchased the car. So the technician did the diagnostic and stated that my vacuum pump had went out but he couldn’t tell me why or how this had happened. I then took the vehicle to my parents house and left it there in the garage for a few weeks to have second opinion done. I then took it to another Kia dealership and they stated there was no vacuum to the brake booster and said there was a broken camshaft and metal pieces were in the engine and the engine needed to be replaced. Again I asked what caused all of this and no one could give me an answer. I had only had the car a 1 1/2 years and don’t understand what caused all of this and I now have a car that I can no longer drive.
