Bentayga vs G-Class

Affected 2019-2023 Bentaygas, including V8, W12, and Hybrid variants, can drop to the lowest ride height, show a suspension fault warning, and suffer compressor or strut failure. A leaking strut can tear the rubber bellows and make the vehicle repeatedly re-level while parked, eventually immobilizing it. A full strut replacement is approximately $3,250 per corner at an independent specialist, while compressor replacement separately runs about $1,200-$2,500.

Bentaygas from 2019-2024 with the optional Dynamic Ride system can develop 48V actuator faults or seal failures that trigger a chassis system fault and noticeably increase body roll. Driving remains possible, but the active anti-roll function is disabled and a failed unit can eventually lead to a no-start if the 48V network is affected. Replacing one 48V actuator at a specialist typically costs around $4,500, with dealer work often exceeding $8,000-$12,000 when related modules are included.

Many 2019-2025 Bentaygas, especially Hybrid and V8 models, suffer parasitic 12V battery drain from telematics and standby electronics, often leaving the car dead after 5-14 days of sitting. Symptoms include low battery warnings, erratic infotainment behavior, and intermittent keyless-entry failure. A specialist battery replacement is roughly $800 including parts and labor, with dealer service and parasitic-draw diagnosis easily exceeding $1,000.

Pre-facelift 2019-2022 Bentaygas commonly experience MMI freezes, black screens, Bluetooth disconnects, and random reboots, with the 2021+ system also showing occasional reboots. Because climate and vehicle settings share the display, a failure also removes control of those functions. A replacement head unit from a specialist costs roughly $2,000-$4,500, while dealer new-unit replacement with labor and coding typically runs $5,000 or more.

Bentley issued recalls for fuel-line routing on 2019-2020 V8 models, oil-separator/PCV failures on V8 engines, and W12 coolant-pump leaks; recall repairs are free. Outside recall coverage, V8 oil-separator replacement costs about $2,000 at a specialist and a W12 coolant-pump replacement can run roughly $3,000-$5,000. Symptoms include fuel smell or visible leak, excessive oil consumption with blue smoke, and coolant loss with potential overheating.

The 2019-2021 Bentayga can have low-speed ZF 8HP jerking, delayed downshifts, and harsh 1-2 or 3-2 shifts, mostly due to TCU calibration rather than hardware failure. A dealer transmission-software update is usually covered under warranty or costs about $500 out of pocket; genuine mechatronic failure is less common and can require a $5,000-$9,000 replacement. Rare cases may trigger a transmission warning and limp-home mode.

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.
