A Cybertruck owner forum has a complaint that when he tried to adjust the temperature while driving, an airbag deployed.

The fact that it was specifically the knee airbag that deployed while the driver was interacting with controls in that vicinity suggests the system may lack proper debouncing or validation logic to filter out false positives.

This is exactly the kind of systemic safety failure that strengthens the Piedmont lawsuit about Tesla’s defective approach to vehicle safety integration.

• False crash signal generation: airbag control module may have received bogus deployment signals, possibly from electrical noise or a fault in the crash sensor network
• CAN bus cross-contamination: touching the climate control (which communicates via CAN) may have introduced signals that the airbag system misinterpreted as a deployment trigger
• Grounding or electrical isolation failure: low-voltage interface action affects a safety-critical system
• Software logic error in the airbag deployment algorithm
