I was driving at 45 mph during a sunny day with normal traffic flow. The right rear tire had suddenly exploded. It almost caused a major accident. Upon inspection, the tire was totally blew out. Only the rim was left. The tire expert at Northside Lexus dealer in Houston said he had seen hundreds of blow out tires on Lexus like that. He didn't want to alert NHTSA. The tires were made by Dunlop in 2023. My car had only 20,000 miles on it. Please consider to recall this kind of Dunlop Sport Maxx tires before another accident or fatality happens. Thanks.

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.

We are the owners of a 2023 Lexus RZ450e Luxury, a fully electric vehicle. My wife and I rely on the Lexus app (on our Android devices) to monitor essential details such as remaining miles, charging percentage, and the overall status of the vehicle. These features are vital to ensure we have sufficient charge before driving. However, as of Monday, October 14th, the app has stopped displaying this crucial information. Instead, it shows â-1 mi. estâ and â-1 %,â (minus one percent!) and the status bar has disappeared entirely. Please refer to the attached screenshot for reference. This exact issue occurred previously in July 2024, and Lexus opened file number 240710002913 to address…
