What can fail
The roof rail air bag inflator end cap may detach or the inflator sidewall may rupture, preventing the air bag from deploying properly.
The 2019 Chevrolet Silverado 3500 has 7 recalls, the most serious being roof rail airbags that can rupture or shed an end cap, sending metal fragments into the cabin during deployment.
The roof rail airbag issue appears across multiple filings covering different cab configurations, but the core danger is the same: the inflator end cap can detach or the inflator sidewall can burst, releasing compressed gas and propelling fragments toward occupants rather than providing protection. Prior repair attempts did not fully resolve the issue, which is why it appears under several campaigns.
On the fire side, trucks equipped with the optional Duramax 6.6-liter diesel engine and an engine block heater cord face two related concerns. The heater cable or its connection terminals can develop an electrical short circuit, and a separate filing notes that a short can damage engine components directly. Both situations raise the risk of a fire, and this applies only to vehicles with the optional block heater.
There is also a fuel system concern on trucks equipped with the optional dual tank setup. The rear fuel tank can collapse inward, which stops the fuel pump from moving fuel forward to the front tank. When that transfer fails, the engine can stall unexpectedly, leaving the driver without power in traffic.
