Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

My vehicle has violently jolted 10+ times while driving at low speeds (15–30 mph) in all drive modes. The jolting is severe enough to feel like being rear-ended and poses an immediate safety hazard. The check engine light came on during one incident. My dealership told me they cannot diagnose or repair the vehicle because they do not yet have software for 2026 Mercedes models, leaving the vehicle unrepairable and unsafe to operate. I no longer feel safe driving this vehicle and am requesting investigation and manufacturer action.
