Fuel pump on other Yukon years
No other Yukon model year has enough reports of fuel pump for a sheet of its own. See every Yukon year.
What this problem usually is
A lot of fuel pump complaints are tied to a recall. Owners describe a car that stalled or wouldn't start, sometimes at highway speed, and many mention that a recall covers it and the part isn't available yet. Others paid for the pump themselves before a recall existed, or on a car the recall didn't include.
What got replaced
Owners who name the part that was replaced mention the fuel pump (36 reports).
Recalls and investigations
5 recalls on the fuel and propulsion cover the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.
The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.
The transmission control valve may fail and cause the rear wheels to lock-up.
The rear wheel driveshaft assemblies may have internal components that were not heat-treated properly, possibly resulting in driveshaft failure.
The fuel pump power control module may cause the fuel pump to fail or operate intermittently, which can interrupt fuel flow to the engine, and cause an unexpected engine stall.
The fuel tank assemblies may be missing adhesive between two layers of the fuel tank shell which may result in a fuel leak.

Is this a known problem?
The manufacturer has sent NHTSA 2 service bulletins or notices for the 2021 GMC Yukon 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.
This service bulletin provides service information for customer concerns of an in-tank fuel pump whining noise, engine hard to start and/or stalls and Malfunction Indicator Lamp (MIL) is illuminated that may be caused by gelling of fuel in cold temperatures.

Should you keep driving it?
This page can't tell you that. 0 of 36 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.
