I am reporting a severe, systemic vehicle performance discrepancy on my 2025 Lexus TX 350h (2.4L Turbo Hybrid powertrain). The vehicle is officially labeled with an EPA rating of 23 MPG combined. However, under normal, conservative driving conditions, the vehicle routinely achieves only 17-17.7 MPG—a consistent 26%+ shortfall from the manufacturer's certified window sticker metrics. I have never gotten EPA higher than 17.7 since owning the new car. This has drastically limited the vehicle's safe total driving range to under 300 miles per tank. The shortfall persists despite cautious driving in Eco Mode and after passing the engine break-in period. This issue matches a widespread pattern reported by numerous other owners in consumer forums, pointing to a potential defect in the vehicle’s fuel management software or hybrid battery management logic. I request that NHTSA log this tracking data to investigate whether the manufacturer misrepresented the vehicle's real-world operational capabilities or fuel-system integration. I have a separate compliant #11762922 open for extreme safety concern related to visible gas vapors and overpowering health concerning gasoline smell at times which have occurred 5 times that I have recorded; unsure if this issue is related. Please investigate all the Lexus TX and Toyota Grand Highlander formal NHTSA complaints, Lexus Tickets, Technical Service Bulletin requests, and the previous Lexus Service repair for fuel leaking being a fire hazard - the fix was a fuel tank protector under Service Campaign #25LC05. My car had this protector installed; ironically there were no incidents of the gas smell & visible vapors until AFTER the service campaign and install of the fuel protector; coincidence or not. It seems highly probably that the following 4 issues are related on these cars: 1) fuel leaking/protector installed 2) gas mileage off 3) Visible gas vapors 4) strong gas smell. Please act before someone gets hurt. This is a family car w kids.

I would just like to say that the info instrument panel in my Lexus does not light up satisfactory to see when there’s daybreak. I think this is a safety hazard when you can’t see the numbers because of the sunshine. I think this is a safety issue that should be addressed by Lexus anytime you can move the instrument cluster info and you cannot read the numbers then there is a problem. I haven’t seen where many people have complained about it, but I do know that mine is not the only one that has this problem. Thank you.

The contact owns a 2025 Lexus TX350. The contact stated that while driving 50 MPH, the brake pedal was depressed and felt spongy, and the vehicle failed to respond as intended, causing the braking distance to be extended. The vehicle was taken to the dealer, where the contact was informed that the brakes were in good working condition; however, the failure persisted. The contact stated that while attempting to raise the folded passenger's side third row seat to the upright position, the back of the seat became stuck to an unknown part behind the seat, causing the seat to fail to respond as needed. The vehicle was taken to the dealer, where the contact was informed that the unknown part had been replaced, and the seat could be raised; however, the failure persisted. Additionally, the contact stated that fuel tank door had failed to open intermittently while pressing the release button on the steering wheel, forcing the contact to release the fuel tank door by engaging the emergency release manual button inside the trunk. The dealer was notified of the failure, and an appointment was scheduled for a diagnostic test. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 3,000.

We were driving down the highway and the vehicle started shaking. I immediately slowed down as I felt we had a flat. There was notification on the screen. I moved to the right onto the shoulder. Only after we were completely stopped did I see a low tire warning come on display. I slowly got out as the traffic was heavy. I could see the outer section of the tire came apart from both sides. As we were in a dangerous location someone called the police. Two police cars pulled behind us and provided us some safety. We agreed to swap out bad tire for spare as we were in a very dangerous location and needed to get vehicle moved before someone ran into all of us. We did look at the highway to ensure no objects were in the road. I didn’t see any while driving, but we wanted to verify to protect other drivers. There also weren’t any pot-holes in highway. We inspected tire after taking it off and there were no screws, nails, objects, or damage to the center tread/sides. The tire seemed to separate fairly cleanly on both sides. Tires were Continental Cross-contact 255/45 R22 107V LX20 (Eco plus) To repeat, no Warning Lights came on vehicle before tire came apart. I have sent message to my insurance company. No one has inspected tire and it is in my possession.

We have had 2 windshields crack on the Lexus TX350, with very low impact to the windshield by very small road debris. Both windshields require(d) replacement due to long migrating cracks. There are several issues with the windshields on the TX350 per online searches. The windshields are a laminated acrylic one that are prone to cracks requiring replacement. This is a common issue on the TX350. The windshields are on long back orders for a genuine Lexus part. We are having our second windshield replaced on XXX at the Lexus dealer. I am of the opinion that this issue should be looked into by NHTSA for a potential recall and improved manufacturing process for future original equipment and genuine Lexus replacement. Our TX350 will be available for inspection on XXX at Parker Lexus in Little Rock Arkansas. The approximate cost to replace the windshield is $1850.00. We are not claiming the windshield on our insurance for this replacement for fear of potentially being cancelled by our insurance company. Please research this issue at your earliest convenience and feel free to request more information from me if needed to help in the assessment of the problem. We look forward to hearing from you asap. Thank You! [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

y 2025 Lexus TX500h experienced sudden and complete AC failure at fewer than 25,000 miles, 18 months after purchase. The selling dealer diagnosed a refrigerant leak from the AC condenser and denied warranty coverage citing road debris impact damage. No photographic documentation of a discrete impact event or specific leak point was provided to support the denial. This failure is consistent with a documented, systemic design vulnerability in the Lexus TX platform. The vehicle's wide-open front grille design allows road debris direct access to the AC condenser, which sits as the frontmost component in the cooling stack with no protective barrier. Multiple NHTSA complaints document identical failures on TX platform vehicles at extremely low mileages including 580 miles and 900 miles, with dealers uniformly denying warranty coverage. Operating without AC in Texas summer heat constitutes a safety hazard, particularly for child passengers. I am requesting NHTSA investigate this as a systemic design defect pattern across the TX platform. Attached photos include: (1) photos provided by the dealer as their evidence of "impact damage" — none of which document a specific leak point or impact deformation zone; and (2) photos taken by the owner of the condenser on the Westside Lexus loaner vehicle provided during this service visit, which show comparable fin condition and debris accumulation to the denied vehicle. The loaner vehicle photos demonstrate that this condenser condition is consistent with normal operation in this environment, not discrete impact damage.
