I have had my 2023 RZ450e for two years and at 53,000 miles, the driver side daytime running light went out. Another owner on a Facebook Lexus RZ450e group reported the same identical thing happening to them in October 2024. With the headlight assembly being LED, these should not fail early on in ownership and should last quite a while. My vehicle has been inspected by Lexus dealership at the service intervals, most recently May 8, 2025 and there was no mention of DRL on driver side being out from the service advisor. No warnings were available. I found out through the reflection of being behind someone when stopped. Having one functional DRL can be a hazard especially in the rain.
