Ranking Every Lexus LS Generation From Worst To Best
While Lexus’s flagship sedan has consistently impressed, not every generation has been created equal.
You’ll find the first generation (1989-1994) ranking 1st, pioneering the segment with its near-flawless design.
The third generation (2000-2006) ranks 2nd, boasting a larger V8 engine and advanced technologies like voice-controlled navigation.

The fifth generation (2017-present) ranks 4th, offering a twin-turbocharged V6 engine, but its hybrid model falls short.
The Worst Generation: Fourth Generation (2006-2017)
You’ll find that the fourth generation of the Lexus LS, spanning from 2006 to 2017, fell short in several key areas.
Specifically, its engine performance was underwhelming, reliability issues arose more frequently compared to other generations, and its overall design didn’t quite meet expectations.
These shortcomings earned it the title of the worst generation of the LS.
Poor Engine Performance
Engine problems plagued the fourth generation of the Lexus LS, making it the worst generation for engine performance.
You’ll want to avoid the 2007 model year, which had faulty oxygen sensors and engine issues on top of transmission problems.
The 2009 model year also experienced a high number of reported issues with the engine and transmission.
Even the V8 engine wasn’t immune to problems.
While brake actuator failure was a separate issue, it’s clear that engine performance was a major weakness in this generation of the Lexus LS.
Reliability Issues Arise
The fourth generation of the Lexus LS, spanning from 2006 to 2017, earned a reputation for being the most problematic.
You’ll find a slew of reliability issues, with transmission problems being a common complaint.

These common problems make the fourth generation a reliability nightmare.
Design Falls Short
While reliability concerns plagued the fourth generation of the Lexus LS, its design shortcomings further marred this already troubled era.
You might’ve expected a luxury sedan to excel in design, but this generation fell short.
The introduction of the F Sport trim, felt out of place.

Furthermore, its luxurious features failed to impress, making this generation a letdown for many LS enthusiasts.
A Slightly Better Generation: Fifth Generation (2017-present)
Lexus’s fifth-generation LS, launched in 2017, signals a significant departure from its predecessors.
You’ll notice it’s swapped the V8 engine for a twin-turbocharged V6, giving it more presence and a better chance of competing with its German rivals.
The ride is smooth, and the interior is whisper-quiet, but it’s not as quick or dynamic as the best S-Class or 7 Series.
The hybrid model’s CVT combined with a four-speed automatic underdelivers on performance expectations.
The interior is superbly detailed, but it was initially marred by the Remote Touch Interface, which was later improved with a new touchscreen from the 2022 model year.
A Refined Generation: Second Generation (1994-2000)
You’ll appreciate the buttery-smooth powertrain that makes the second-generation LS a highly relaxing car to drive.
