Owner report 11755359 · 2026-08-06 (August 6, 2026)
Vehicle experiences a severe, abrupt jerk/jolt during deceleration around the 5th-to-4th gear downshift. The issue occurs consistently when slowing down. Dealership verified the condition on Repair Order #1906625 and confirmed a transmission flaw. Dealer stated software is required from the manufacturer with no ETA for release. The abrupt deceleration creates unexpected cabin jolting during normal traffic slowing.

When the malfunction occurs, both display screens suddenly go completely black and become inoperable while the vehicle is running. During these failures, the vehicle also produces a repetitive clicking sound from the dashboard area while…

Owner report 11695851 · 2025-10-27 (October 27, 2025)
The instrument panel behind the steering wheel has gone totally dark. This issue happened about a month ago but resolved itself somehow. Issue happened again and will not correct itself. Took vehicle to dealer and they could not resolve issue with software update. Upon researching the MBWorld.org user forum I noticed this may be a wide spread issue. With a dark/blank instrument panel you cannot know your speed, fuel level, or what gear you have placed the car in. My technician even indicated he has seen this issue on several 2025 MB models.
