XM vs G-Class

The most commonly reported issues for the 2019-2026 G-Class are MBUX infotainment failures, A-pillar wind noise, and driveline vibration. These problems are most prevalent on 2019-2021 models, with later years showing fewer reports. The infotainment issue can cause the backup camera to go blank, while the wind noise and vibration are primarily comfort concerns.

Yes, the MBUX central display in 2019-2023 G 550 and AMG G 63 models can intermittently go black, freeze, reboot while driving, or show a blank backup camera after a cold start. This is a safety-relevant nuisance because the rear camera view can be lost, and the vehicle setup menu may be briefly inaccessible. Mercedes issued software updates and some 2019-2021 units required head-unit replacement under warranty.

Yes, 2019-2020 G 550 and AMG G 63 models, and some 2021 examples, can have persistent whistling or roaring from the front upper door or A-pillar at highway speeds. In a minority of cases, wind-driven water can drip onto the door sill or kick panel, potentially leading to damp carpets or door-area electrical connector issues. Mercedes performed seal adjustments or replacements under warranty on early builds.

Yes, 2019-2021 G 550 and AMG G 63 models can have a shimmy or vibration at 65-80 mph that persists after wheel balancing, and the 9G-Tronic automatic can have clunky 1st-to-2nd gear engagement and harsh downshifts at low speeds. The vibration is often traced to the driveshaft, while the shifting issues were addressed with transmission-control software updates. Severe shift complaints can progress to valve-body wear.
