Recommended and avoid configurations

RECOMMENDED CONFIGURATIONS (THE 'BUY' LIST)

  • S500/S550 (M278 V8 Engine)

    • Praised for robust performance and durability, especially in pre-facelift models (2015-2017), provided regular maintenance is performed.
    • Considered a reliable engine choice within the W222 generation, offering strong performance with smooth power delivery.

  • S400 (M276 V6 Engine)

    • Reported to have a lower complaint density compared to other engine options.
    • Offers a capable and smooth petrol V6 experience, often found in earlier models of the W222 generation.

  • S350d (OM642 V6 Diesel Engine)

    • Many owners report overall satisfaction and good fuel economy for long-distance driving.
    • Provides ample torque and performance suitable for the S-Class.

CONFIGURATIONS TO AVOID (THE 'LEMON' LIST)

  • Models equipped with Magic Body Control suspension

    • This highly complex system is known for expensive failures of components like ABC (Active Body Control) pumps and valve blocks, leading to significant repair bills.
    • Air struts can leak, causing suspension sagging and requiring costly replacements.

  • S350d (OM642 V6 Diesel) 2016 model year

    • Subject to a 2016 recall due to a wiring harness located too close to the exhaust system, posing a risk of failure.

  • Early 7G-Tronic Automatic Transmission (pre-software updates)

    • Some customers experienced rough downshifting and upshifting, particularly between second and third gear, although Mercedes-Benz often released software updates to resolve these issues.

Used car buyer guide (Australia)

Common problems & platform risks

For the Mercedes Benz S Class model year 2016 (2014-2020), recurring issues often cluster around specific engines, transmissions, and shared chassis electronics. The trust score reflects how often serious powertrain or drivetrain problems show up in real-world reports versus routine maintenance. Always verify with a pre-purchase inspection and service history.

What to inspect before you buy

Use the platform-wide inspection list above for leaks, rust, suspension wear, and electronics. On a test drive, listen for drivetrain noises, check transmission behaviour when hot, and scan for warning lights. In Australia, heat and urban short trips can accelerate wear—factor in climate-appropriate servicing.

Best engine or trim to target

A typical starting point is configurations similar to: S500/S550 (M278 V8 Engine). Cross-check against the recommended list and your budget; the "sweet spot" often balances fewer reported failures with parts availability.

Configurations to be cautious about

Sources frequently flag higher risk around: Models equipped with Magic Body Control suspension. That does not mean every car fails—use it as a prioritisation list for inspection and price negotiation.

Ownership cost signals

Higher reported failure rates usually mean more workshop time and parts cost. Before buying, get quotes for common jobs on this generation (timing, fluids, suspension, transmission service) from an independent specialist familiar with the brand.

What should I inspect on a used Mercedes Benz S Class model year 2016?
Air suspension system (AIRMATIC) component failures, including leaking air springs (air struts), faulty compressors, and ride height sensors, which can lead to uneven ride height, sagging, or a bumpy ride. Complex electrical system glitches, affecting the COMAND infotainment system (freezing screens, unresponsive controls), driver-assistance features, central locking, power windows, and causing unexplained battery drain. Oil leaks from various engine components, such as valve cover gaskets, oil pan gaskets, turbo oil lines, and oil filter housings, particularly as the vehicle ages or accumulates higher mileage. Potential for timing chain tensioner issues and check valve problems in higher mileage M278 V8 engines, often indicated by a rattle on startup.
