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 NHTSA log this tracking data to investigate whether the manufacturer misrepresented the vehicle's real-world operational capabilities or fuel-system integration.

Severe safety issue! Pulled the vehicle into the driveway after a drive and put the vehicle in park and turned the car off. With key still in the vehicle, exited vehicle, closed driver door and went to open drivers-side rear passenger door where 2 year old baby was in car seat. Before being able to open the rear door, the car went dead and locked down all the doors (key is still inside the car). Could not get into car through any of the doors, including rear hatch. Tried the manual back up door handles (since this vehicle has electronic door releases), but none of them worked. All the while, baby is crying in the car and it's more than 85F outside. In panic, call Lexus roadside assistance. They advise that help may take 90 minutes and with baby in vehicle, we should call 911. After call to 911, fire and police arrive. Fireman tries all manual backup door handles (which are there in case battery dies and electronic release don't work) then takes crowbar to the door (bent door frame and A pillar, and other damage to car). Door still not open! Door is later opened by service tech and we successfully get baby out. Had another incident where after drive, put vehicle in park and turned off vehicle. The vehicle power immediately went dead (no lights, no ignition, nothing) and I couldn't exit car even when using the manual door handles. Had to sit and wait in car for a while until power came back to get out. This is extremely dangerous because someone could get stuck inside the car in traffic or somewhere else and be in death box unable to exit. Or someone, including kids, could get locked without. The physical key inserted under the door handle tab and using the manual override handles still doesn't work - it's an extremely dangerous design flaw. There was a police report made by Franklin Park, Illinois PD. We don't have a copy of the report yet.
