Complaint Timeline
Chronological view of owner reports
Traveling at 65 MPH in the right-hand lane * Driving Assistance ON * Traffic Sign Assist ON * Speed Limit Adoption ON Staying in the right-hand lane, I pass by an offramp Sudden deceleration to 20 MPH – Phantom braking This has happened twice traveling past the same offramp. Since, I have turned the Speed Limit Adoption OFF Note that this particular off ramp has more than one speed limit sign (yellow) visible from the freeway. My guess is that the Mercedes is reading the off ramp signs and interpreting them to be for the freeway and not for the off ramp. I consider the sudden deceleration to be dangerous
