By Hari Vinayak · Updated 2026-06-12
Quick answer
A 2018 Jeep Grand Cherokee in good condition with average mileage (about 100,000 miles) is worth roughly $18,250 in a private-party sale — a fair range of $16,800 to $19,700, or about $21,000 at a dealer. 2018 is not on our years-to-avoid list, so condition, history, and maintenance matter more than the model year here.

Compare the best and worst Grand Cherokee yearsWhat to check before you pay
- Quadra-Lift air suspension (2014+): compressor and strut failures — confirm it raises/lowers through all modes and holds height
- 2011–2013 3.6L: cylinder head failure on the left bank — ticking or misfire on cylinders 2/4/6; many were replaced under extended warranty
- 2011–2013 TIPM (power module): fuel pump relay and electrical gremlins — intermittent no-starts are the symptom
