2014 Kia Optima Service and Repair Manual

The 2014 Kia Optima came in three distinct powertrains — a turbocharged 2.0L, a naturally aspirated 2.4L and a 2.4L full hybrid — and each carries its own factory figures. This service and repair manual is matched to the exact 2014 model year, engine and trim, so the specifications and sequences are the ones Kia published for your car, not near-matches pulled from a different year or engine.

Known issues on the 2014 Optima. Seven recalls are on federal record for this model year. One concerns the engine itself: machining errors during the engine manufacturing process may cause premature bearing wear, and bearing wear may result in the engine seizing, increasing the risk of a crash. Three more involve the fuel system, where the low-pressure fuel hose may deteriorate and a fuel leak in the presence of an ignition source can increase the risk of a fire — two of those campaigns cover vehicles that had already been serviced under an earlier Kia recall. The remaining three cover the Hydraulic Electronic Control Unit (HECU) in the antilock brake system: brake fluid may leak inside the unit, and an electrical short in the HECU increases the risk of an engine compartment fire while parked or driving. Owners have filed 777 complaints for the year and Kia has issued 193 technical service bulletins.

From inspecting engine bearings to replacing a low-pressure fuel hose or diagnosing the HECU in the antilock brake system, it keeps you on the OEM procedure and the correct specification for your specific 2014 Optima.
