Catastrophic engine failures, including seizing and internal component damage (lifters, rods, pistons), are a significant concern. Some failures occur at very low mileage, suggesting potential manufacturing defects. Estimated repair cost: $4,000 - $10,000+.

Complaints include transmission control valve failures leading to rear wheel lock-up (diesel variants) and general loss of power. These often correlate with engine problems but can also be independent transmission faults. Estimated repair cost: $1,000 - $5,000+.

Electrical System Malfunctions

Issues include stalling, system malfunctions, and camera failures. Software glitches and module communication problems can contribute to these issues. Estimated repair cost: $200 - $1,500.
