The short answer
Based on available data, the Ford Expedition comes out ahead of the Chevrolet Suburban on fuel economy and power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is mixed and heavily dependent on model year and generation. Long-term owner reports for older generations (GMT400, GMT800, and early GMT900) frequently praise their durability, comfort, and capability as workhorse vehicles, with some considering them reliable and appreciating assets. However, feedback on newer generations (specifically 2015+ models) reveals significant and recurrent concerns regarding expensive electrical and powertrain failures occurring well under 100,000 miles.
Best version to buy
Insufficient owner data available to identify a consensus "best" model year or trim. Positive remarks are directed at older generations (e.g., 2000-2006, 2010-2014) for reliability, and at the 2025+ models for their updated interior electronics and dash design.
Known issues
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.
