The short answer
The Ford Expedition offers fuel economy, while the Lexus GX excels at long-term reliability instead. Choose the Ford Expedition if you prioritize fuel economy in daily driving, or the Lexus GX if long-term reliability matters more for your needs. Both are covered by real owner reports on CarWizz.
Overall
Mixed sentiment with a clear generational divide. Long-term owners of older models, particularly those with the 5.4L Triton V8 (e.g., 2013 model), report very high reliability with only routine maintenance required, describing them as "rock solid" and "so reliable." However, sentiment shifts significantly for newer generations equipped with the 3.5L EcoBoost V6 and the Ford/GM co-developed 10-speed automatic transmission. These models are frequently criticized for severe and recurrent transmission failures ("jerk, clunk, bang"), cam phaser issues requiring engine work, and other premature mechanical failures.
Best version to buy
Insufficient owner data available to declare a consensus "best" model year or trim. Data suggests avoiding specific problematic years is more critical than seeking a particular trim.
Known issues
Overall
Sentiment is sharply divided by generation. The previous-generation GX 460 (model years up to 2023) is overwhelmingly praised for its legendary reliability, proven V8 powertrain, comfortable and durable luxury, and high long-term value. Owner feedback describes it as a "bulletproof," over-engineered vehicle that benefits from decades of refinement, with a 10-year cost of repairs reportedly half that of competitors.
Best version to buy
For the GX 460 generation, the final model year (2023) is specifically highlighted as the "one to have" due to receiving the latest updates and a newer infotainment system with Apple CarPlay/Android Auto. The Luxury trim is highly recommended for its adjustable ride control (Comfort/Sport settings), which owners find invaluable for tuning ride quality on different road surfaces.
Known issues
The verdict
The Lexus GX is the better choice for most buyers.
It has stronger reliability sentiment in owner reports than the Ford Expedition, based on the data above. If the specific known issues on the Lexus GX are a dealbreaker, the Ford Expedition is worth a closer look instead.
