ELECTRICAL SYSTEM
Went to my car on Saturday @630p to put items in my car for church the next morning. I couldn't get into my car and my car wasn't responding to my key fobs. I called the Lexus service and was closed. I got on my app and called roadside service. As I was walking (pacing) in my garage, I noticed my rear passenger tire was flat! I asked the AAA rep about my tire. He said no replacement was in my car and the tire isn't inflated with air, but foam. Additionally, he noted me not driving the car may have drained my battery. Which was about 73% last I drove it. When he looked at my car and jumped it, he noted my 2nd battery was drained. He didn't know why. He had me leave the car running for an hour after he left. I did and the car turned off automatically after 1 hour. I called both the service department at your location and AAA on Monday morning. On Monday 8/10/2026, I got the car towed and called Gabb6 at the service center. Upon further review, the SOS button is malfunctioning and is killing my battery. Tuesday 8/11/2026, tire will be replaced but there is no solution for the malfunction other than disconnecting the SOS feature, which is a safety hazard in case anything happens. I understand there are multiple vehicles at this moment at the dealership with this issue. This should be recalled as if families with small children or citizens have an issue and connect get to their phones, the SOS feature should be functional.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY, LATCHES/LOCKS/LINKAGES:DOORS:LATCH:EMERGENCY MECHANICAL RELEASE
Incident one: I was locked out of my car and needed to call Lexus roadside assistance for help. The technician struggled with the mechanical override to open the car, but was able to force it eventually. He explained the 12V battery was dead. There was nothing left on that would have drained the battery. Incident two: The following week, I was able to enter the vehicle and turn it partially on but was not able to drive the car and after I turned off the power, I was trapped in the vehicle. Lexus roadside assistance came again and jump-started the 12V battery. I left it at the dealership behind another brand new Lexus RZ with the same issue!

ELECTRICAL SYSTEM
This a new 2026 electric car with an~80% charge in the traction battery. Unfortunately the 12 V battery failed after I got into the car and closed the car door. Nothing on the car worked including the door locks leaving me trapped. Fortunately I had my phone with me so I could call for assistance. I shudder to think if I had not or if my grand kids had been playing in the car while we weren’t around. . In talking to Lexus roadside assistance something similar had occurred in south Florida that required a 911 call to save the guy inside. This is a serious problem.

POWER TRAIN, ELECTRICAL SYSTEM, VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM
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.

UNKNOWN OR OTHER
Beginning in September 2025, I experienced respiratory symptoms, including coughing, chest discomfort, and shortness of breath, that appeared to be triggered when entering or operating my vehicle. The symptoms consistently improved when I was not using the vehicle and returned upon re-exposure. The specific component responsible is UNKNOWN. I suspect a possible cabin air quality, HVAC, or material-related issue, but I am not able to identify a specific failed part. My safety was put at risk because symptoms occurred while driving, including during traffic conditions, which affected my ability to breathe comfortably and concentrate. The issue has been reproducible. The vehicle was inspected by a Lexus dealership and later by a Toyota/Lexus Field Technical Specialist. No warning lights or dashboard alerts were present. The inspection did not identify a cause, but the symptoms persisted. The vehicle remains available for inspection. This report is being submitted to document a potential vehicle safety or air quality concern for further review.

SUSPENSION, STEERING
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.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION, LANE DEPARTURE: ASSIST
I am reporting a safety concern involving a 2024 Lexus RZ300e related to battery range performance and charging requirements in cold weather. In real-world winter conditions in Massachusetts, the vehicle experiences severe range loss, requiring excessive and repeated public charging to remain operable. On a representative day, I was required to use multiple public charging networks (ChargePoint, FLO, and Tesla Superchargers), spending over 4 hours physically charging, consuming approximately 105 kWh of electricity, and paying nearly $50 in public charging costs, with additional home charging still required for the next day. Many charging stations are outdoors and poorly sheltered, requiring prolonged exposure to freezing temperatures, wind, and precipitation. This creates a significant safety risk due to driver fatigue. To earn a modest daily income, I must drive for extended hours. When combined with approximately 4 hours per day spent charging, this results in up to 16 hours in a single day spent driving or waiting in the vehicle. Charging time is not rest, as I must remain alert, manage charging sessions, and relocate the vehicle. This extended time causes physical exhaustion and reduced alertness, increasing risk on public highways. These conditions are particularly concerning because my wife is pregnant, and the vehicle was leased as a family vehicle. Prolonged winter charging exposure and fatigue pose risks not only to the driver but to passengers and other road users. The vehicle has been inspected by a Lexus dealer. Dealer documentation states that battery degradation cannot be directly measured, usable battery capacity data is unavailable, and cold-weather range loss is considered “normal.” No corrective repair or adjustment has been offered. The issue is reproducible in winter conditions and remains unresolved. I believe the vehicle’s real-world charging burden and resulting fatigue create an unreasonable safety risk and warrant review.

WHEELS, UNKNOWN OR OTHER
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.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
While operating my 2025 Lexus RZ 300e at normal road speeds, the vehicle experienced a sudden and dangerous propulsion loss when the traction battery reached 0% state of charge. The only advance notice was a single soft audible alert. There were no escalating warnings (visual or audible) and no meaningful low-battery reserve to allow the driver to safely exit traffic or reach a charging location. Within seconds of the single alert, the vehicle entered reduced-power “limp mode,” creating an immediate traffic hazard. This abrupt reduction in speed occurred in active traffic among large trucks, putting my safety and the safety of other road users at serious risk. The lack of progressive alerts and absence of a usable reserve buffer prevented any safe corrective action and increased the risk of a collision or injury. Lexus marketing materials, sales claims, and the owner’s manual indicate that the RZ’s battery management system provides intelligent, progressive warnings and adequate reserve energy to prevent drivers from being stranded. My vehicle did not perform in accordance with these stated safety features. This represents a potential defect in the warning system and energy reserve calibration. The vehicle is currently in the custody of the authorized dealership. I requested that the service department attempt to recreate the incident to determine whether the system functions as designed. They refused, citing an open claim with Lexus corporate. Lexus corporate closed my initial claim without investigation six days after it was filed and has not inspected the vehicle. This failure mode—no escalating alerts, no sufficient reserve, and sudden loss of propulsion—is a clear safety concern that should be investigated for possible noncompliance with FMVSS requirements for driver warnings and vehicle control.

EXTERIOR LIGHTING
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.

ELECTRICAL SYSTEM
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.

EQUIPMENT:ELECTRICAL
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.

ELECTRICAL SYSTEM, POWER TRAIN, VEHICLE SPEED CONTROL
The contact owns a 2023 Lexus RZ 450. The contact stated that while the vehicle was in park(P), the vehicle failed to shift out of park after multiple attempts. The vehicle eventually shifted into drive(D) and as the contact began to drive the vehicle, the vehicle began to hesitate as the brake warning light appeared on the instrument panel. Once the contact reached her destination and parked the vehicle, she attempted to straighten out her vehicle as the tail end was sticking out in the road. While straightening the vehicle, the brake warning message returned on the instrument panel as the vehicle then surged forward at a high rate of speed. The vehicle ran over four garbage bins before crashing into a parked vehicle. The air bags deployed upon impact. The contact attempted to exit the vehicle after the crash but all the doors failed to unlock from the inside. The contact screamed for help as neighbors heard the commotion outside and assisted the contact out of the vehicle. Police were called but no assistance arrived. The contact did not sustain any physical injuries and did not seek medical attention. The vehicle was towed to an independent mechanic where it remained in their possession. The dealer was notified of the failure but offered no assistance. The manufacturer was notified of the matter and stated that they would review the vehicle's black box. The vehicle had yet to be repaired. The failure mileage was approximately 5,400.

SEAT BELTS
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.

UNKNOWN OR OTHER
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.
