Lexus filed this with NHTSA as a service bulletin dated Mar 6, 2026, received Apr 8, 2026, about the engine. It names 6 model years (2024–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 46 complaints with NHTSA since 2015. 2 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.
On Saturday, August 22, 2026, while traveling on the highway with my two toddler-aged children in the vehicle, the temperature gauge entered the red zone and the vehicle automatically reduced power due to overheating. This forced me to navigate a power-reduced vehicle on a highway with minor children — a serious safety hazard.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lexus L-TT-0349-26 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-TT-0349-26 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-TT-0349-26 cover?
The manufacturer filed it against 6 model years: 2026 Lexus NX, 2026 Lexus RX, 2026 Lexus RZ, 2025 Lexus RZ, 2024 Lexus RZ, 2026 Lexus TX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
