Lexus filed this with NHTSA as a service bulletin dated Apr 24, 2026, received May 8, 2026, about the engine. It names 5 model years (2023–2025).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome customers of 2023 – 2025 model year RX 350h, RX 500h, and 2024 – 2025 model year TX 500h vehicles may experience one or more of the following complaints when the low fuel level warning light illuminates: • The total amount of fuel dispensed during refueling is less than the customer expects when the fuel nozzle automatically clicks off, preventing the customer from being able to put as much fuel into the tank as expected. • The low fuel level warning light illuminates earlier than the customer expects. • The driving range is reduced compared to customers’ expectations, resulting in more frequent refueling than customers anticipate. The combination meter software logic has been updated to help meet customer expectations.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 233 complaints with NHTSA since 2015. 32 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
When removing foot from gas pedal the rpm shoot up to almost 4k instead of switching to EV mode or dropping to 1k rpm’s. This has scared my wife causing her to slam on brakes as she thought throttle was stuck since the rpm’s shot up. This is dangerous. It doesn’t happen all the time and Lexus did duplicate it but said was normal

When we purchased this car in June 2024 it did not have an engine revving issue. The engine, electrical or transmission maybe all of them have SERIOUS SAFETY ISSUES! When driving and you let off the gas pedal the engine starts revving very loudly, it scares the heck out of you because you don't know if you can stop!
2024 Lexus RX · Engine · filed with NHTSA Sep 3, 2025 · ODI 11684648
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.
2025 Lexus TX · Engine · filed with NHTSA Jun 22, 2026 · ODI 11745699
A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lexus L-SB-0010-26 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the L-SB-0010-26 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Toyota warranty extension on file lists the ones Toyota has filed.
Which vehicles does L-SB-0010-26 cover?
The manufacturer filed it against 5 model years: 2025 Lexus RX, 2024 Lexus RX, 2023 Lexus RX, 2025 Lexus TX, 2024 Lexus TX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
