NHTSA Complaint #11438750 — 2021 FORD EXPLORER

Vibration: First use of the day, at about 35 MPH vehicle exhibits vibration throughout, especially around 40-41mph. Felt in steering wheel, seat, and with a loud rumble often heard. Has been since car was new. Has a vibration in rear view mirror at highway speeds. Goes away after driving for 15 miles or so, and at least a half hour. Returns after vehicle cools off. Cruise control: Adaptive cruise sometimes causes extreme braking at highway speeds for no reason. This happened while driving past a vehicle on Alligator alley causing all my passengers to comment, even though I had not touched the brake. Happened again 10/28 on 75 coming down from Sarasota. Braking: ABS engages on dry roads, especially when turning, for example into a driveway, but it cold be just a normal stop for a traffic light. The brakes also “grab” when coming to final stop, causing the car to stop suddenly
