Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2015, 2016, 2017, 2022, 2026.

What this problem usually is

This is the biggest drivetrain group on the site: a transmission that shudders, slips, hesitates or bangs into gear. It's the everyday version of transmission trouble, where the car still drives but doesn't drive right, and it has three narrower sheets of its own for jerking, hesitation and slipping.

Is this a known problem?

The manufacturer has sent NHTSA 6 service bulletins or notices for the 2021 Ford Expedition that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

“Most mornings when I shift the vehicle from Park to Drive the transmission slams into gear and it feels like the vehicle just hit a wall. Also when shifting from 4th through 8th gear the transmission shudders through the shift sequence and sometimes it completely cuts out, total loss of power and have to coast to a stop on the side of the highway. This happens all the time.”

Should you keep driving it?

This page can't tell you that. 0 of 43 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
