2023 Lexus UX 250h Battery Replacement

Battery replacement for the 2023 Lexus UX 250h involves more than swapping hardware: it requires careful diagnostics, safety protocols, and post-installation system checks. Our warranty-backed service process begins with a complete electrical and hybrid system scan to confirm whether the 12-volt battery or components of the high-voltage hybrid pack require service. For 12-volt replacements, technicians replace the battery, verify charging voltage, test accessory power and clear any related codes. High-voltage hybrid work follows strict manufacturer safety steps, specialized tooling and detailed testing to preserve battery management integrity. Choosing Nalley Lexus Smyrna ensures the replacement uses genuine OEM parts and correct programming so system calibrations remain factory-spec. This minimizes the risk of future faults and maintains resale value.
