NHTSA Complaint #11470386 — 2016 KIA SORENTO

My family and I own a 2016 Kia Sorrento VIN [XXX] that we purchased from a dealer in August 2017. It was reliable transportation; we were very pleased with it; it was serviced with regular oil changes, maintenance, etc., and had no mechanical issues until early September 2021. The vehicle’s temperature gauge began to register hot, i.e., way over to the “H” during operation. Our regular mechanic at an AAA-registered auto care center replaced the thermostat, but the car was still overheating. After an expensive but thorough diagnosis from early November through early December 2021, the mechanics – including a Kia specialist – confirmed that the head bolts were pulling away from the engine block or the source of our problem. After searching the internet, I understand that this is not a frequent occurrence but not uncommon among the same model and year Kia Sorento's with similar mileage. Replacement engines are not available due to supply issues; there was no guarantee of success from our mechanics or the machine shop who could attempt to mill the head/engine block and drill-tap for new bolts; and the entire process was cost prohibitive. Therefore, we elected not to have it repaired. Our Sorrento that is past its engine-drivetrain warranty with 124K miles on the odometer sits in the driveway with a year’s worth of car payments remaining.
