widespread · 150 NHTSA complaints · electrical
-
Premature frame and rear-subframe rust, with owners reporting holes and structural failure on relatively low-mileage salt-belt trucks; can render the truck unsafe or a total loss.
commonly reported · 40 NHTSA complaints · typically 90k–130k miles · body
-
Heater blower-motor resistor and connector overheat and melt, a documented fire hazard with flames reported at the floorboard.
occasional · 15 NHTSA complaints · electrical

Wiring harness in the extended-cab door breaks from repeated door cycling, triggering airbag and seat-belt-tensioner warning lights and disabling those systems.

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
- Simple, durable drivetrain, the 3.7L inline-five and later 5.3L V8 are regarded as long-lived, and the truck is easy and inexpensive to service.
- Compact, maneuverable midsize footprint that is easy to park and place compared with a full-size pickup.
- Affordable to buy used and body-on-frame tough for light work and modest towing.
Cons
- Dated, plasticky interior, modest ride comfort and few safety features by modern standards.
- Salt-belt frame and subframe corrosion is a serious, well-documented weakness on early trucks.
- The 3.5L five-cylinder valve-seat issue makes pre-2007 trucks the ones to scrutinize.
- Chronic Passlock anti-theft no-start strands owners and was never recalled.

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 ($15,390). Higher trims started higher (up to $16,590), 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.
