2024 Hyundai Santa Fe Check Engine Light Codes

In Peoria, AZ, drivers bring their 2024 Hyundai Santa Fe to Larry H. Miller Hyundai Peoria for precise code diagnosis and trusted repair. Common codes for this model often include P0420 (catalyst system efficiency), P0135/P0136 (oxygen sensor heater circuit issues), and P0300-P0304 (misfires). Ignoring P0420 can lead to reduced fuel economy, increased emissions testing failures, and possible catalytic converter damage that can cost thousands to replace. Left unchecked, oxygen sensor faults (P013x) reduce fuel efficiency and accelerate exhaust component wear. Misfires cause rough running and can damage pistons, catalytic converters, and ignition systems — resulting in higher long-term expense. Our certified Hyundai technicians use OEM parts and factory diagnostic tools to identify root causes quickly, cutting diagnostic time and preventing unnecessary replacements. Choosing our dealership provides clear pricing, warranty protection, and immediate savings through accurate repairs and fewer repeat visits. We invite you to schedule service online and review current service specials to maximize value.
