Recalls & safety
Recall history hasn't been loaded for this model year yet.
Whether a recall is still open on a specific car depends on its VIN. Check it free at NHTSA's VIN lookup (nhtsa.gov/recalls), or ask the seller for proof the repair was done.
Pros & cons
Pros
- Class-leading towing and payload for a midsize truck, with an available 3.6L V6 and a torquey 2.8L Duramax diesel.
- Comfortable, car-like ride and a quieter cabin than most rivals of its era.
- Strong fuel economy from the available diesel and good resale value.
Cons
- Interior materials and base infotainment feel cheap for the price.
- The 2015-2016 electric-power-steering-loss defect is a serious safety concern; confirm the recalls are complete.
- The 8-speed automatic is prone to shudder and torque-converter problems, especially 2017-2018.

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 ($21,100). Higher trims started higher (up to $39,600), 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.
