Used car buyer guide (Australia)

Common problems & platform risks

For the Mercedes Benz Gle Class model year 2018 (2016-2019), 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: GLE 350d (OM642 V6 Diesel) with 9G-Tronic Transmission. 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: AMG GLE 63/63 S (M157 V8 Bi-Turbo). 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.
