2024 Lexus TX problems

Filed Oct 16, 2026 · Acceleration, Engine · AZ

2024 Lexus TX 500h Luxury. Since I bought it new, the vehicle has intermittently failed to accelerate from a stop. I have reported it to my Lexus dealer at every 5,000-mile service. Lexus TAS case numbers:[XXX] and [XXX]. The dealer applied Lexus TSB L-SB-0026-25 (Hesitation From a Stop), a TCM reprogram. It reduced how often it happens but did not fix it. It still occurs, and is worse in Arizona summer heat with the A/C on max. It matches the TSB conditions: it happens when the energy monitor shows about 30% (3 of 10 bars) and within about 5 minutes of starting the vehicle. What happens: I am stopped at a green light waiting to turn left. When a gap opens I press the accelerator, and the vehicle coasts through the intersection at about 5 mph even with the pedal fully to the floor. I have nearly been hit by oncoming traffic while stuck in the intersection. A left turn across traffic depends on the vehicle accelerating when commanded, and this one does not. I no longer trust the vehicle to accelerate when I need it, so I have to wait for much larger gaps and take extra care on every turn across traffic. A second symptom: pulling away from a red light, the transmission suddenly downshifts and the vehicle lurches forward. The engine revs unexpectedly with no change in pedal input. My dealer has told me they have seen other TX 500h vehicles with this same problem after the TSB was applied. Other the federal safety agency complaints describe the same failure on the TX: ODI 11768652, 11653862, 11730468, 11679221, 11758930, 11697848, 11589001 and 11752837. Lexus's own TSB confirms the condition exists, but the fix is incomplete. The RX 500h shares the same powertrain and is covered by the same TSB. RX owners report the same failure: ODI 11621814, 11733235 and 11615471. The vehicle is available for inspection. I am asking the federal safety agency to investigate loss of acceleration from a stop on the 2024-2025 TX 500h and 2023-2025 RX 500h before it causes a crash.

I am reporting a severe, systemic vehicle performance discrepancy on my Lexus TX 500h (2.4L Turbo Hybrid powertrain). The vehicle is officially labeled with an EPA rating of 27 MPG combined. However, under normal, conservative driving conditions, the vehicle routinely achieves only 20 to 21 MPG—a consistent 20%+ shortfall from the manufacturer's certified window sticker metrics. 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 the federal safety agency log this tracking data to investigate whether the manufacturer misrepresented the vehicle's real-world operational capabilities or fuel-system integration.

I had my foot on the brakes waiting at a red light. The car just started jerking back and forth. It didn’t stop until I released my foot off the brake.

I am filing this complaint regarding my 2024 Lexus TX. A road rock/debris entered through the vehicle’s factory front grille and struck/punctured the A/C condenser, causing the air conditioning system to stop functioning properly. The repair cost is approximately $2,500. The factory grille has large openings that leave the condenser vulnerable to direct impact from normal road debris. Lexus does not have a protective screen or guard that can be installed to prevent this type of damage. This design flaw has affected many other Lexus TX owners and I think they need to offer up more protective measures to avoid this from happening over and over again.

Strong smell of gas coming from around the car and near rear end of car. Usually after a drive. The smell does not happen after every drive. I brought up the smell to my husband a number of times within the year…and finally took to JD Auto in Arizona in June but the gas smell could not be replicated and no source or defect could be visually seen. No recall for this has been reported by Lexus. dealership. No check engine light has been recorded. Worried that there is some internal issue that could cause huge problems. I do have children who have also reported smelling the gas in the back seat.
