2022 Lexus ES 300h Check Engine Light Reset

At Park Place Lexus Grapevine we explain why a proper diagnostic and targeted repair are superior: OEM-level scanning preserves accurate records, ensures warranty compliance, and targets the actual fault rather than hiding symptoms. Our team uses factory software to clear codes only after confirming repairs, then verifies repairs with a test drive and re-scan.
