Lexus RZ Reliability by YearBest & worst years, problems & recalls — NHTSA data

Vehicle Completely Locks itself. Not able to open doors. Even Not able to open with keyless remote fob. Not able to take Charging cable connection out of vehicle. It has happened twice. Lexus was made aware of this issue. I have been stranded twice. It is a safety issue and requesting NHTSA to recall.

My 2023 Lexus RZ450e experienced a sudden failure of the 12-volt battery, which completely disabled the vehicle and prevented it from starting. The battery failed while the car was plugged into a Level 2 home charger, but not in ‘Ready’ mode. There were no warning signs or alerts, and I had to call roadside assistance to jump-start the car. After the incident, I brought the vehicle to the dealership. They tested the 12V battery and said it was “fine.” However, during the 100,000-mile maintenance, I specifically requested a battery re-check—and this time, the battery failed the test. This raises serious concerns about the reliability and longevity of the 12V battery in this vehicle, as well as the inconsistent diagnostics at the dealership. If the vehicle had failed to start while I was away from home, I could have been stranded in unsafe conditions. Safety Concerns: The 12-volt battery powers essential systems, including door locks, ignition, and electronic control units. Its failure disables the entire vehicle. The fact that this happened while the car was plugged in, but not in “Ready” mode, suggests a potential design flaw or charging system issue. I’ve also seen reports from other RZ450e owners experiencing similar 12V problems, which may point to a broader systemic issue. Requested Action: Please investigate potential defects in the 12-volt battery system and whether the Lexus RZ450e’s charging system fails to maintain battery health during regular use.

The contact owns a 2024 Lexus RZ 300E. The contact stated that while the vehicle was parked and charging, the heater was activated and failed to function and provide heat as needed. The contact stated that the charging system intermittently failed to charge as needed. The contact stated that there was an hour-and-a-half delay for a full charge. The vehicle was taken to the dealer but was not diagnosed or repaired. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 35,620.

This evening upon driving home my 2.5 year old son began crying. When I investigated, he was crying because his car seat had turned over on its side. When we arrived home I tested the rear seat belts and none remain locked; therefore his seat was not secured. Please advise how this can be fixed as soon as possible as it is not safe for us to use the vehicle until this is addressed.

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 manufacturer’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 vehicle’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.

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.

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 dealer’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.

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 “-1 mi. est” and “-1 %,” (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 it. While it was resolved at that time, the problem has resurfaced, leaving us once again unable to monitor the vehicle's charge remotely. This ongoing issue is frustrating and inconvenient, especially given the safety implications of not being able to reliably monitor the vehicle’s charge. We expect better from a $70,000 luxury vehicle, and it is unacceptable that such a problem has recurred. It raises serious concerns about the testing and quality assurance of the mobile app updates. Resolution Request: We find it unsafe to operate the vehicle without reliable access to charge status information via the app. Given that this issue has recurred, we kindly request a resolution. Ideally, we would prefer the vehicle to be replaced, as this persistent issue has significantly impacted our ownership experience. We appreciate your prompt attention to this matter and look forward to your response.

The contact owns a 2023 Lexus RZ 450E. The contact stated while driving 65 MPH, the vehicle made an abnormally loud popping sound and stalled. Several unknown warning lights were illuminated. The contact was able to pull to the side of the road. The vehicle was towed to the local dealer, where it was being diagnosed. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 10,000.

When the passenger side radiant heat is on, it makes a toxic smell that smells like plastic or glue melting. It has happened in our RZ and also in a loaner RZ (VIN [XXX] ). Lexus has done nothing that we are aware of to ensure that this smell is not affecting passenger side airbags or the integrity of the cars. They’re also hiding in their notes that they have experienced the smell. I took the Service Manager Jon Howell on a drive in both cars and he smelled the melting smell and agreed he understood why I was describing it as melted hot glue or plastic. However, those drives are not documented in the service notes. I am concerned this is a flaw in the car for which the impact of safety is unknown. Further testing must be done to ensure these cars are safe after the radiant heat is used and the smell has occurred. The smell is constant any and all times the radiant heat is engaged. We have experienced the smell at least ten times in our car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

It is two problem with Lexus Rz. First the Glass Roof is not UV protected and My husband and I are getting burn on our head and my phones over heat because of the strong sun beating on us. Second is the Electric range supposed to be 220 mile range and in reality I am getting 150-160 range. we are misrepresented by Lexus. On Oct.13 Lexus inspected the car and Please see the attached file. The guy says that this car cannot be in highway or freeway. He says that Avoid relying on the displayed possible driving distance. I paid close to $80000 including warranty and they took my car for 29900. I want my money back or they have to give a car that would not be like this.
