NHTSA Complaint #11481739 — 2013 KIA SPORTAGE

My engine started making a tik-tik noise in June of 2022. I drive very little as I work from home, took it to get an oil change and for a service check, was advised nothing was wrong that they could identify on the vehicle. Ticking continued, Kia advised they were over a month out for service call appointments, got on the list and had my oil changed again after only 300 miles. Ticking noise got louder while waiting on service call appointment, then as I was driving home on a back road (thankfully), there was a loud banging noise from under my hood, spluttering, some whining noises, my instrument panel lit up with all engine-related lights, and the car shut off while driving. I lost power steering and brakes, and had to coast into a neighborhood and down a hill to safely move my car out of traffic's way. I had my 7 year old with me in the vehicle and have since had it towed to Kia, and was advised there was a 'voluntary maintenence' KSDS sensor I was supposed to have had installed in order to extend my currently-intact 100K/10 year factory warranty, and because they did not update my contact information correctly when i moved I never received the notification. My car is currently sitting at the Kia dealership, undriveable, and I am having to fight Kia to cover the engine replacement.
