Hi all. Bought my 2021 Tahoe LT on September 7th. It has been in the shop twice since then for this issue. “Service safety restraint system”.
The first time I took the car in, the warning light came on and off repeatedly. The second time the warning light was showing less frequently.
Today when I picked up the car I asked a ton of questions. Thanks to your posts here I felt fairly well armed. Today they gave me a copy of an internal bulletin.
“Some customers may comment on a Service Safety Restraints Sytem message displayed in the DIC. When checking for DTCs, a B14DC symptom 1B and or 13 will be set in the K36 Resyraints Contol Module. This DTC is for an open or high resistance in the F106DA Driver’s front seat in order airbag deployment loop”
Hope this helps.
Hope their fix actually sticks.
Good luck!
