The short answer
Based on available data, the Jeep Grand Cherokee comes out ahead of the Ford Expedition 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 sharply divided and heavily dependent on model year and generation. Long-term owner reports for the WK2 generation (approximately 2011-2021) indicate a pattern of initial satisfaction followed by significant reliability concerns, particularly after surpassing 100,000-120,000 miles. Owners of earlier models (e.g., 2005 with the 4.7L V8) express concerns about durability and high maintenance costs.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Isolated positive reports exist for the V8-powered models (e.g., Summit Reserve) for their power and towing capability, and for the Overland trim of the WK2 generation for its luxury features.
