Reliability favors the Acura MDX by a slight margin over the Mercedes-Benz GLC. The MDX costs less to repair and has far fewer recalls. Both rate good, and owner complaint rates are close. The GLC's fire reports, piston failures, and roof defects are the bigger worries.

How Do the Acura MDX and Mercedes-Benz GLC Generations Compare?

Most used GLCs a shopper will see are first generation, which covered the 2016 to 2022 model years and got a facelift for 2020. That puts 2018 and 2020, the weakest years, in the same generation. The second generation began with the 2023 model year. On the MDX side, the third generation ran from 2014 to 2020, with a facelift in 2017, and 2019 and 2020 fall there as its weakest years. The fourth generation arrived with 2022 and received a facelift for 2025. The newest model years on both cars have had less time to collect complaints, so their clean records say little yet.

Verdict

The Acura MDX is more reliable than the Mercedes-Benz GLC, scoring 72/100 vs 69/100.

A slight edge goes to the MDX. Both models rate good, and owner complaint rates are close. The deciding factors are cost and recalls: the MDX is cheaper to keep running, visits the shop less often, and carries far fewer recalls across the same eight model years. Its own problems are serious, including worn connecting rod bearings and a pause and lurch when pulling away. The GLC has cracked pistons and roof panels that come loose. Neither car is trouble free, so the MDX wins on running costs more than on freedom from defects.

What Are the Common Problems With the Acura MDX and Mercedes-Benz GLC?

Electrical faults top both lists, but they look different. GLC owners report fires, sudden power loss with no restart, and a screen that reboots and blacks out the rear camera.

The GLC adds costly, specific failures: a crankcase ventilation valve, cracked pistons, and panoramic roofs that shatter or lift. The MDX hesitates for a second or two when pulling away, and worn connecting rod bearings can end an engine. Steering is a crash-linked area on the GLC with 3 crash-linked complaints. The MDX has no steering category among its main problems.

Who Should Buy the Acura MDX vs the Mercedes-Benz GLC?

Pick the MDX if you want lower running costs and fewer recalls to chase. Before you buy, test it from a stop for the pause and lurch, and ask whether the connecting rod bearing recall work was finished. Be cautious with 2019 and 2020, its weakest years. Its electrical reports include two under-hood fires, so check for open recalls by VIN. Pick the GLC if you prefer a compact SUV and can accept higher upkeep. Skip 2018 and 2020, its weakest years. Check the recall history by VIN, and ask whether the panoramic roof is fitted, since reported failures there came at roughly 25,600 to 40,000 miles and one dealer quoted $10,484 for a replacement. Also confirm engine warranty status, because one owner was told an engine needed replacing just past 50,000 miles. Treat 2026 on either car as unproven. Newer years have had little time to collect complaints.
