Overview

2018 Kia K900

The 2018 Kia K900 presents a strong value proposition for used luxury sedan shoppers. It delivers a comfortable ride, a potent V8 engine, and a well-appointed interior, often at a fraction of its original cost. However, a significant safety recall concerning potential engine compartment fires due to an HECU electrical short demands careful attention. While consumer complaints are absent, this recall history warrants a thorough pre-purchase inspection and verification of completed repairs.

Critical Failure Risk

A potential electrical short within the Hydraulic Electronic Control Unit (HECU) module can lead to an engine compartment fire risk. This is a critical safety concern that has prompted multiple recalls.

Early detection can help you avoid a $300-$700 repair.
