Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Highest: 2006 (362 complaints). Lowest: 2010 (14).
Mixed sentiment with a clear divide between appreciation for its off-road capability and criticism of its on-road performance, reliability, and value.
Described as sluggish, struggling with highway merging and towing, "feels like it belongs in a lawn tractor".
Automatic transmissions (particularly the 4-speed) noted as a weak point not expected to last beyond 200,000 miles; specific mention of failures linked to owner misuse (shifting while moving).
Tendency to run hot, especially under load or in hot climates; idle temperatures reaching 3/4 gauge indicative of a weak radiator fan; risk of internal radiator failure mixing coolant and transmission fluid ("pink milkshake").
Blower motor control module failures, especially in early models (e.g., 2006); subject of a major safety recall for connector/harness overheating.
Described as low quality; thick C-pillars and small rear window create significant blind spots.
