The short answer
Based on available data, the Ford Expedition comes out ahead of the Chrysler Aspen 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
Sentiment is sharply divided and heavily dependent on the specific generation discussed. For the 2007-2009 SUV model, owner experiences are polarized. A subset of long-term owners report deep satisfaction, praising the vehicle's comfort, towing capability, smooth handling, and overall utility when properly maintained, with some expressing strong loyalty over nearly two decades of ownership.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Anecdotal feedback suggests the 5.7L HEMI V8 is strongly preferred over the 4.7L Magnum V8 for adequate power, especially when towing.
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.
Known issues
The verdict
The Ford Expedition is the better choice for most buyers.
It has more power on its best-equipped version than the Chrysler Aspen, based on the data above. If efficiency matters more to you than outright power, the Chrysler Aspen is worth a closer look instead.
