A proper battery replacement for the 2023 Lexus IS 350 involves careful steps that only a certified service center can fully and reliably perform.

Dealer-performed replacements reduce the risk of improper installation, which can cause corroded terminals, loose connections or compromised circuits that lead to more costly repairs.
