Stalling on other Tahoe years
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: 2016, 2017, 2018, 2026.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the battery (11 reports) and the fuel pump (3 reports).
Recalls and investigations
4 recalls on the electrical system cover the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.
In the affected vehicles, an electrical signal short may cause the transfer case to shift to neutral without the driver's input.
The radios in the affected vehicles may become inoperative, and as a result, there would be no audible chime to notify the driver if the door is opened with the key in the ignition or no audible seat belt warning indicating the seat belts were not buckled.
The subject vehicles may have a transmission oil cooler line that is not securely seated in the fitting.

Is this a known problem?
The manufacturer has sent NHTSA 11 service bulletins or notices for the 2015 Chevrolet Tahoe 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.

What owners wrote
“Transmission delays in shifts. Whine coming from transmission as well. New torque converter and thermal bypass installed with new transmission fluid and filter. Truck was diagnosed and itâs okay in Chevrolets computers. This is a scary and unsafe way of feeling scared if transmission will fail.”

“Vehicle has shut down twice while turning. When action happens the stability controls are turned off, parking assistance is turned off. All lights on dash flash. With this vehicle having electronic steering, I have no control of this vehicle when it shuts down while driving. Dealer could not reproduce actions to diagnose, but informed me to return if it was to happen again.”

Should you keep driving it?
This page can't tell you that. 0 of 40 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.
