Airbag on other Tahoe years
No other Tahoe model year has enough reports of airbag for a sheet of its own. See every Tahoe year.
What this problem usually is
Airbag complaints split into a few kinds. The most common is an airbag warning light that won't go out. Others involve the passenger seat sensor switching the passenger bag off with an adult sitting there, an airbag that didn't deploy in a crash, or one that went off without a crash at all. A large share also come from owners waiting on a recall part.
What got replaced
Owners who name the part that was replaced mention the occupant sensor (9 reports).
Recalls and investigations
One recall on the airbags covers the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.
The communications gateway module incorrectly processes a loss of communication with the sensing diagnostic module (SDM), causing the air bag malfunction indicator light to inconsistently illuminate.

Should you keep driving it?
This page can't tell you that. 2 of 27 reports involved a crash and 3 people were hurt. 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.
