The short answer
Based on available data, the Ford Expedition comes out ahead of the GMC Suburban on 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
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 broadly positive, with a strong appreciation for the vehicle's core attributes of immense space, comfort, and long-term durability across many generations. Owner discussions frequently highlight the Suburban's unparalleled utility for hauling people and cargo on long road trips, with specific praise for its comfortable ride and spacious interior even when fully loaded. There is a notable divide in feedback based on vehicle age.
Best version to buy
For newer models (2021+), the High Country trim with the 6.2L V8 engine and AWD is specifically cited as an excellent configuration, offering strong performance and comprehensive features. For older models, the 2500-series (particularly with the 7.4L or 8.1L big-block V8 engines) is held in high regard for its durability and capability.
Known issues
