The failure pattern owners describe
Buyer takeaway: 2021 Tahoe owners report frequent 'Service Safety Restraint System' warnings that recur within days to weeks of dealer repair, often triggered by seat position changes; dealers confirm that when the warning is active, airbags may not deploy in a crash. At least one owner experienced actual airbag non-deployment in a frontal collision.
Owners of 2021 Chevrolet Tahoes report recurring "Service Safety Restraint System" warning lights that appear early in ownership—sometimes within a week of purchase—and cycle on repeatedly while driving, anywhere from every 2–5 minutes to every few miles. The warning often returns within a day or two after dealer repair, even after a 2022 recall attempt. The problem is linked to faulty seat connectors, short or damaged harnesses under the driver's seat, and broken wires; seat adjustment or passenger seating can trigger or worsen the alerts. When the warning is active, dealers confirm the airbags cannot be guaranteed to deploy in a crash. One owner experienced actual airbag non-deployment after significant frontal damage. Parts replacement costs have been quoted around $1,250, and parts availability has delayed repairs by weeks. A dealer-performed TSB did not resolve the issue in at least one case. Chevy corporate has offered only partial cost coverage in at least one instance, refusing recall coverage despite the safety implication.

The 'Service Safety Restraint System' warning lamp illuminates repeatedly or stays on, triggering airbag readiness warnings. Owners report the light cycling on and off every few minutes to every few miles, sometimes triggered by passenger seating or seat adjustment. Dealers confirm that when this light is active, airbag deployment cannot be guaranteed in a crash.
