2018 Kia SorentoRecalls, problems, MPG & safety

“My 2018 Sorento is consuming oil excessively. I’m having to add oil between changes, and I’m now experiencing reduced acceleration under load. I have been told by a few different parties that this has become a common problem with Kia’s. I want an oil-consumption test performed and I want the VIN checked for all engine campaigns, warranty extensions, KSDS coverage, and open recalls”

“The vehicle’s ignition system began malfunctioning immediately after a recall-related service (Campaign CS2312 – ignition cylinder protector installation) performed on January 9, 2026.

My vehicle is part of a nationwide class‑action lawsuit involving engine defects and theft vulnerabilities. Because Kia America delayed resolving my warranty case, the vehicle has been sitting at Kia Vacaville accumulating predatory storage fees. The dealership is now threatening a mechanic’s/storage lien sale, which would destroy the vehicle and eliminate evidence of the manufacturer defect. I cannot afford any repair costs, storage fees, or loan payments for a vehicle that failed due to manufacturer defects.
