Kia America, Inc. (Kia) is recalling certain 2016-2017 Rio, 2016-2018 Optima, 2017-2018 Optima Hybrid and Optima Plug-in Hybrid vehicles. The trunk latch base may crack, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."

The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak.
Kia Motors America (Kia) has recalled one 2016 Optima vehicle. In this vehicle, the end seal for the driver's frontal air bag inflator may not have been properly installed, possibly resulting in reduced inflation of the frontal air bag in the event of a crash.

“I am reporting a serious safety concern involving my 2016 Kia Optima, purchased from CarMax in 2024 and financed through CarMax Auto Finance. On or about October 5, 2026, I returned to my parked vehicle and discovered extensive black soot/smoke residue throughout the interior. Wiring and interior components appeared melted or burned. The vehicle had not been involved in a collision. Based on the damage, I believe an electrical or wiring failure may have caused the fire, although the exact cause has not yet been confirmed. The vehicle was inspected by police and the tow operator, and it was determined to be a total loss. An insurance claim has been filed, and the vehicle should be available for inspection if requested. This vehicle also had a significant history of mechanical problems. Since shortly after I purchased it, it experienced severe oil consumption/oil loss, requiring multiple visits to CarMax and multiple 1,000-mile oil-consumption tests. I also experienced repeated spark plug and coil pack problems requiring repairs/replacements. The exact component that failed is currently UNKNOWN. I have not yet had Kia inspect the vehicle or confirm the cause of…”

Kia advised at the time that the wiring harness should be replaced due to electrical issues at the time but said that there was no recall for that work. At the time, there were no electrical failures of steering, brakes, all power etc. Nor did we know that those were a possibility. The wiring harness quote was $7,000, over the cost of the vehicle. It was decided to continue repairing the electrical issues as they came up, it was assumed that the fuses would blow before there because a safety or total vehicle failure, as automobiles are designed that way. 8/4/2026 the vehicle experienced a complete and total loss of power resulting in a traffic crash into another vehicle as the brakes felt like you were trying to push a wall rather than a pedal. There was minimal physical damage to the other car and the kia, the other driver got my husband's insurance information and then…”
