Pros & cons
Pros
- Capable midsize towing and good off-road ability in Pro-4X form.
- Sturdy body-on-frame construction with the proven 4.0L VQ40 V6 and lots of metal parts where rivals use plastic.
- Strong resale value relative to price.
Cons
- Dated interior and below-average fuel economy.
- Early D40 (2005-2010) carries the radiator/transmission 'milkshake' failure risk; inspect the cooling system.
- VQ40 timing-chain tensioner wear and fuel-sender failures are common on the earliest years.

Depreciation
Move your cursor along the line to see the estimated value for any year.
This listing sits above the typical depreciation curve. Common for heavily-optioned cars and for 2021-2023 model years (pandemic-era pricing); the curve is anchored at base MSRP, which excludes options.
Curve anchored at the entry-trim base MSRP ($16,550). Higher trims started higher (up to $23,300), and options added more.
The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
