Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While making a left turn at low speed, I applied the brakes, but the vehicle did not respond as expected and instead appeared to drift, surge, or accelerate forward. The vehicle struck a fire hydrant and a bus stop pole before crashing into a tree. Airbags deployed and both occupants sustained injuries. I suspect a possible malfunction involving braking, propulsion, electrical, or speed control systems. No final cause has been determined. The vehicle should still be available for inspection. Mercedes-Benz USA has opened a case regarding this incident.”
NHTSA complaint #11731921, filed 2026-04“We were driving locally, and the car stopped abruptly for no reason. There was no one and nothing in front of it, no animal around, and no reason for the stop. Had there been someone behind us, we would have had a big problem. We called the salesperson at the dealership only to learn that he had moved to Germany. We were told that another representative would return my call in about six minutes. No one called. A week later, we were on the highway and, also for no reason, the car slowed abruptly, and then resumed its speed. It happened a third time on a local street. …”
