My vehicle, a 2023 Lexus RZ 450e, has been out of service for over 30 days due to an unresolved HVAC system failure affecting cabin heating. The issue significantly impacts the safe operation of the vehicle, particularly in cold weather conditions where adequate heat is necessary for driver visibility and occupant safety. Despite the vehicle remaining under the manufacturerâs warranty, the dealership has been unable to provide a diagnosis completion or estimated time of repair.  The vehicle was brought in for service on February 20, 2026, and has remained at the dealership since that time. During this period, no clear resolution timeline has been provided, and communication from both the dealership and manufacturer has been limited to general status updates with no substantive progress. The lack of heating functionality raises safety concerns, especially given the vehicleâs reliance on electronic systems for climate control.  A loaner vehicle has been provided; however, the extended delay without repair or replacement raises concerns about potential defects in the HVAC or related electrical systems. The inability to resolve the issue within a reasonable timeframe suggests a possible systemic defect that is affecting other vehicles of the same make and model.  This complaint is being submitted to document the prolonged repair delay, lack of resolution, and safety implications associated with the loss of heating functionality in the vehicle.

While driving slowly in a parking lot and without striking any object, my 2023 Lexus RZ 450e experienced a catastrophic front right suspension failure. The suspension failure caused separation of the CV axle, detachment of the front right wheel assembly, and an immediate loss of steering control. The vehicle became inoperable and required towing. Fortunately, this occurred at low speed and no injuries occurred. The vehicle became inoperable and required towing. No injuries occurred due to the low speed at the time.

LEXUS RZ 2023 STEERING

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.

LEXUS RZ 2023 UNKNOWN OR OTHER

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.

The charger fails to charge.  Nothing happens when it is plugged into the vehicle.  The dealer has confirmed the vehicle can be fully charged using the dealerâs level 2 charger.  I am able to fully charge the vehicle using the level 1 charger supplied with the vehicle.  Enel X Way has discontinued support.  Even though I still have one year warranty left on the charger the support page indicates support is no longer provided and Enel X is no longer accepting claims.
