2025 Lexus TX 350 problems

“My 2025 Lexus TX 500h has experienced an intermittent loss of acceleration from a stop approximately four times. The most recent incident occurred on September 27, 2026, at approximately 25,000 miles. At the time of the incident, the vehicle was in Eco mode. The engine had been started approximately five minutes earlier. I drove through a parking lot that is on a slight incline and came to a complete stop at a stop sign where the parking lot exits onto a public road. When I attempted to make a left turn onto the roadway, I pressed the accelerator, but the vehicle would only move at approximately creep speed. I pressed the accelerator further, including fully depressing the accelerator pedal, but the vehicle still did not accelerate normally. This condition lasted for approximately 15 seconds. After that, power gradually returned and the vehicle began accelerating normally. There were no warning lights or warning messages during the incident. Because this occurred while I was attempting to turn left and enter normal roadway traffic, the unexpected lack of acceleration created a significant safety concern due to approaching traffic. The vehicle operated normally…”

“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…”

“The electronic throttle control, vehicle speed control, and powertrain/transmission control system failed. When I press the pedal to accelerate there was no power. However I did not lose power to the vehicle as I can see the vehicle was in Drive mode but was not moving forward. I was on a decline hill and the decline helped me go downwards before a truck could hit me. This total loss of acceleration has occurred exactly 2 times within a 4-week period. The vehicle is currently located at the Lexus dealership service center and is available for immediate inspection upon request. My wife and small children were in the vehicle when the accelerator pedal went completely dead while driving. The sudden drop in speed in active traffic almost caused us to be catastrophically rear-ended by an 18-wheeler semi-truck. After one minute of zero throttle, the vehicle violently jerked, locked us into a highly dangerous 5 MPH limp mode on the road, jerked a second time, and then suddenly resumed normal speed. My family's lives were put at extreme risk. No. The vehicle is currently at the authorized Lexus dealership for inspection, but the service department states they cannot…”

“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…”

“On our 2025 Lexus TX350, less than 1 year old, and under normal driving conditions, our AC stopped working suddenly. Upon inspection at the dealership, they determined a rock or road debris came through the front grill and impacted the condenser, which caused a major refrigerant leak and ac to stop working. I believe this was due to a poor design of the lower half of the front grill, it’s wide open and offers little to no protection to ac and engine components. They should have a better honeycomb or similar grill to protect components. The refrigerant leak is an environmental and road safety issue, and living in hot climates like southern Nevada, when it’s 110 degrees outside, the heat inside the vehicle with no AC is a safety issue for children, adults, etc. The dealership did not cover repairs under warranty, and quoted $3,500 to repair either with cash or submit insurance claim.”

“While stopped in traffic with my foot firmly on the brake pedal, my vehicle began accelerating forward unexpectedly. The vehicle seemed "possessed". It was as if the gas pedal was fully on the ground while my foot was still on the brake, so the car was lurching and seemed to be fighting itself. The vehicle continued moving forward and would not stop despite sustained and hard brake pressure. I was rapidly closing distance on the vehicle in front of me and narrowly avoided a collision by inches. The vehicle only stopped after I shifted it into park and then I shut the car off. This was a terrifying and dangerous event. The vehicle accelerated against brake input and created an immediate collision risk. I reported this incident to my local Lexus dealership (Lexus of Fife, WA). However, the dealership minimized the event in their service documentation and did not accurately record my description of unintended acceleration while braking. At that time, I was informed that Lexus had issued a Technical Service Bulletin (TSB) related to this issue but has not issued a recall or broadly notified owners. If the manufacturer is aware of this defect and has not initiated a…”
