Common causes include oxygen sensor faults, loose gas caps, catalytic converter inefficiency, and ignition or fuel system issues.

Start with a visual: secure the gas cap, check battery connections, and look for obvious leaks.

At Genesis of Peoria in Peoria, AZ, we frequently diagnose the most common codes that illuminate the check engine light on a 2024 Genesis G90. Typical codes include oxygen sensor faults (affecting fuel trim and emissions), misfire codes (which can lead to catalytic converter damage if unchecked), EVAP system leaks like a loose gas cap, and catalytic converter efficiency warnings. Ignoring each can increase fuel consumption, cause failed emissions tests, and lead to costly component failures. For example, an unresolved misfire can eventually damage the catalytic converter — a repair that can be thousands of dollars compared with a relatively low-cost ignition coil replacement when caught early. Our technicians use factory-grade diagnostic tools and OEM parts, ensuring accurate code clearing and fixes that maintain vehicle longevity. We make diagnostics straightforward, and our service advisors are transparent about costs and timing. Review our service specials and schedule service online to protect your 2024 Genesis G90 and save both now and long-term.
