According to veteran mechanic Alan Gelfand, S-Class cars often start having serious and costly problems after hitting 100,000 miles, particularly with their Airmatic suspension, oil leaks, and advanced electronics, with the Airmatic system being a common culprit for expensive repairs due to its complexity and need for specialized parts and expertise.
Oil leaks, while seemingly a minor issue, can often indicate deeper problems within the engine or its intricate seals. Addressing these leaks effectively requires precise diagnostic work and often extensive labor, contributing to the overall high maintenance burden. Furthermore, the S-Class is brimming with cutting-edge electronic systems, from infotainment and driver-assistance features to engine management. As these systems age, they are susceptible to failures that necessitate specialized diagnostic equipment and proprietary parts, driving up repair costs significantly. The need for certified technicians to handle its complex systems further inflates the cost, as these professionals command premium rates for their specialized knowledge.
The financial impact of these issues is considerable. CarEdge estimates that the ten-year maintenance costs for an S-Class approach $13,000. It is crucial to note, however, that this figure does not even encompass potentially catastrophic transmission or engine repairs, which can easily add thousands more to the total. This means the stated estimate represents a minimum expectation, with the possibility of even higher expenditures for more extensive overhauls. For potential buyers, the S-Class represents a commitment not just to luxury, but to a continuous and substantial investment in its upkeep, particularly once it begins to accumulate significant mileage.
5. **Ram 2500**
While much of the discussion regarding expensive-to-maintain vehicles often centers on European luxury brands and high-performance sports cars, American pickups can also present significant financial challenges.
