This page covers 3 recalls and 12 owner complaints for the 2018 Lexus LS.
Complaints for the 2018 Lexus LS are spread across a small number of reports, so no single system dominates heavily. The fuel and propulsion system draws the most serious concern, with owners describing sudden stalling at highway speeds followed by failure to restart, in at least one case, metal shavings were found in the engine oil, suggesting internal engine wear. Wheel and tire complaints center on uneven inner tread wear across all four tires, which owners report being told has no available remedy. A separate seat complaint describes a structural lump in the driver's seat cushion that causes discomfort and numbness regardless of how the seat is adjusted. One report flags a navigation system limitation around coordinate entry, though that appears to be an isolated concern.

By System
The 2018 Lexus LS has 3 recalls, the most serious being a fuel pump that can fail while driving, stalling the engine without warning and raising the risk of a crash.
Two other recalls affect this model. On vehicles equipped with the Executive Package, internal interference within the front passenger seat assembly can confuse the passenger seat sensor, causing it to misread whether someone is sitting there. In a crash, that misreading can result in the airbag deploying with the wrong force or not deploying at all, raising the risk of injury to the passenger. On the tire side, this recall affects vehicles fitted with run-flat tires: the process used to mount those tires onto their wheels may have cracked the internal sidewall reinforcement layer, which can eventually cause the tread to peel away from the tire. Tread separation at speed significantly disrupts handling and stability.
