2025 Lexus Tx

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 am reporting a recurring potential fuel-system/EVAP safety issue with a 2025 Lexus TX 350 (same as Toyota Grand Highlander). On FIVE separate occasions (May, 6/27, July, 8/14, and 9/8/2026), I experienced an overwhelming raw gasoline odor associated with visible vapors coming from the fuel-filler/gas-cap area. Three incidents occurred after refueling; the two most recent occurred WITHOUT recent refueling and with less than half tank full. On 8/14, with temps in the 90s and approximately 135 miles to empty, I drove 30–40 miles, idled approximately 45 minutes, then drove another 10 miles. The overwhelming gasoline odor and visible vapors occurred again. On 9/8, at approximately 108°F and with 152 miles to empty, I drove 46 miles, idled 27 minutes, then drove another 10 miles. The overwhelming raw gasoline odor and visible vapors again came from the fuel-filler area. A strong gasoline odor was also present underneath/around the driver's-side rear wheel well, but not around the passenger-side rear wheel. This recurring release of gasoline vapors presents a potential fire and occupant/public safety concern because gasoline vapors are flammable. I have kept the vehicle outside after incidents rather than parking it in an enclosed garage near an ignition source. The vehicle is available for inspection. The vehicle was previously inspected by an authorized Lexus dealer for this same concern, and Lexus Brand Engagement opened a case and technical-assistance ticket. The dealer reported no fuel leak and deemed the vehicle safe to drive but did not reproduce the condition. The vehicle was driven only approximately 3 miles at the dealership under different conditions. The problem has since recurred multiple times. There have been NO warning lights or dashboard messages. The repeated visible vapors and overwhelming raw gasoline odor during normal operation raise concerns about a potentially unsafe fuel/EVAP system malfunction.

When starting from a stop, putting foot on the gas pedal the car won’t move. Hesitates for a longtime. It has happened numerous times since purchased new. The manufacturer stated that engineering is looking into it, with no definitive answers. No warning lights. It just won’t go, at times which is a safety concerning especially when crossing with oncoming traffic. Unresponsive.

I am reporting two separate but related fuel-system defects on my 2025 Lexus TX500h (VIN [XXX]) that raise safety concerns and appear to be widespread across Lexus TX and NX hybrid models. FUEL FILLER DOOR FAILS TO OPEN: The electronic fuel filler door intermittently fails to open when the release is activated. It sometimes requires multiple attempts, and at times will not open at all, leaving the vehicle unable to be refueled. This creates a safety risk of being stranded with no ability to add fuel, including the risk of running out of fuel on the road or being unable to refuel in an emergency. The failure appears to worsen in cold weather. This is a widely reported problem on 2022-2025 Lexus NX and TX hybrid vehicles and has been attributed to a faulty electronic fuel-door lock actuator (referenced by owners and parts suppliers as OEM part number 77030-F6020). Owners are frequently forced to use a manual emergency release located behind an access panel in the cargo area in order to refuel. FUEL TANK CANNOT BE FILLED TO CAPACITY: On a near-empty tank, the fuel pump nozzle shuts off after only approximately 8 gallons, despite the tank's rated capacity of approximately 17 gallons. Adding additional fuel requires repeated, prolonged attempts and often only a few more gallons can be added. This significantly reduces usable driving range relative to what the vehicle's fuel gauge and range estimate imply, creating a risk of unexpectedly low fuel and reduced range in situations where refueling options are limited. Other owners have reported the same behavior, and in at least one documented case a Lexus Field Technical Specialist diagnosed the cause as a deformed/defective fuel tank requiring a redesigned replacement. Both conditions are present on my vehicle. I am reporting them so that they are documented at the federal level. No crash, injury, or fire has occurred. I have also raised these issues with my Lexus dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle looses power and hesitates to accelerate from a stop start. This happens when The HV Battery State of Charge (SOC) is below 30%. •The vehicle is in catalyst warm-up mode (cold start). The Motor Generator (MG) is in charge mode. As a result of this scenario I have almost been T boned 3 times while attempting a left turn from my home across a dual carriage lane. And again nearly rear ended because of the lack of power or hesitation. To me this is a big safety concern that Lexus do not have a credible fix for.
