The 2002 Mercedes-Benz G-Class is a boxy, body-on-frame luxury SUV built with serious off-road hardware and a premium cabin, positioned as a high-end alternative to more mainstream full-size SUVs. Known for its iconic design and rugged construction, it’s ideal for buyers who want a timeless, upscale 4x4 with genuine trail capability rather than a soft-road crossover. For 2002, the G-Class remains part of the long-running W463 generation, with continual refinements to comfort, safety, and drivability rather than a full redesign. Its market position is unique: a luxury vehicle with truck-like durability, expensive parts, and strong long-term appeal.

1) W463 BODY-ON-FRAME PLATFORM: Built like a traditional truck with a ladder frame, giving the 2002 G-Class a solid, durable feel on-road and excellent strength off-road. 2) TRUE 4X4 HARDWARE: Full-time 4WD with low range and the G-Class hallmark—three locking differentials (center, rear, and front) for impressive traction in mud, snow, and steep terrain. 3) ENGINE OPTIONS (MARKET-DEPENDENT): Many 2002 models are powered by Mercedes V8 engines (such as the 5.0L V8 commonly associated with G 500 trims in various markets), paired with a smooth automatic transmission. Some regions also offered other gasoline and diesel variants, so verifying the engine by VIN and build sheet is important. 4) LUXURY INTERIOR AND SAFETY: Leather seating, upscale trim, strong visibility, and Mercedes safety engineering typical of the era, with a tall driving position that many owners prefer. 5) TIMELESS DESIGN AND HIGH RESIDUAL APPEAL: The upright styling and heavy-duty hardware keep demand strong, and many buyers seek the 2002 specifically for the classic “old-school” G-Wagen feel.

Shoppers often search “2002 Mercedes-Benz G-Class problems” and “2002 Mercedes-Benz G-Class reliability” because this SUV can be dependable when maintained, but it’s not inexpensive to own. Common issues tend to be age-related wear, electrical gremlins, and fluid leaks rather than catastrophic failures, and repairs can be costly due to premium parts and labor. 1) OIL LEAKS AND SEEPAGE: Valve cover gaskets, front timing cover areas, and general engine seals can seep with age, often showing up around 80,000–150,000 miles depending on heat cycles and maintenance. Small leaks are common; ignoring them can lead to messy engine bays and degraded rubber components. 2) SUSPENSION AND STEERING WEAR: Worn ball joints, control arm bushings, steering damper wear, and shocks are common complaints on higher-mile examples, typically noticeable after 90,000+ miles. Symptoms include wandering steering, clunks over bumps, and uneven tire wear. 3) BRAKE SYSTEM WEAR AND SENSORS: Heavy curb weight means brakes work hard. Owners report frequent pad/rotor replacement compared with lighter SUVs, and occasional ABS/ESP warning lights can be triggered by wheel speed sensors or wiring issues as the vehicle ages. 4) ELECTRICAL AND ACCESSORY ISSUES: Power window regulators, central locking/vacuum-related concerns (varies by configuration), and intermittent instrument or switchgear issues can occur on older G-Class vehicles. These tend to be more “annoying” than disabling but can be time-consuming to diagnose.
