What can fail
The front passenger seat frame may not have enough clearance from its stopper, causing the occupant detection sensor to misread whether someone is sitting there.
This page covers 4 recalls and 10 owner complaints for the 2023 Lexus LX.
Complaints for the 2023 Lexus LX cluster heavily around the engine. Owners most commonly describe sudden loss of power while driving, often accompanied by all warning lights illuminating at once and a dashboard message prompting them to pull over immediately. Several owners report the vehicle entering a reduced-power state, commonly called limp mode, that leaves little time to reach a safe stopping point. One owner reports complete engine failure at roughly 25,000 miles. The fuel and propulsion system draws a smaller number of complaints, with owners describing related propulsion loss consistent with the engine reports. A single complaint references brake behavior. A recurring frustration across multiple engine-related reports is that owners were notified of a safety campaign but told no repair remedy was yet available, leaving them in limbo on a vehicle they consider unsafe to drive.

By System
Complaints are owner-reported and reflect individual experiences, not confirmed defects. They are distinct from recalls. Data sourced from the national vehicle safety complaint database.
The 2023 Lexus LX has 4 recalls, the most serious being an engine that can stall without warning and a transmission that can allow the vehicle to roll unexpectedly when left in neutral.
The engine concern stems from debris that can damage the main bearings inside the V35A engine, causing the engine to stall and cut drive power while the vehicle is in motion. Recalls 2 and 3 describe the same underlying defect across overlapping model ranges and are treated here as a single issue. Separately from that, the transmission can allow the vehicle to move on its own when shifted to neutral if the brakes are not applied, which raises crash risk particularly in parking situations or during low-speed maneuvering.
The remaining recall involves the front passenger seat sensor, which detects whether the seat is occupied by an adult, a child, or is empty, and uses that information to control how the passenger airbag deploys in a crash. On affected vehicles, insufficient clearance between the seat frame and a mechanical stopper can cause the sensor to misread the occupant, meaning the airbag may deploy with the wrong force or at the wrong threshold during a collision, raising the risk of injury to whoever is sitting there.
