NHTSA is far more concerned with emergent safety issues vs. general component failure. Illustrative examples: Headlight bulbs that burn out / fail at a higher than expected rate are generally not recall-worthy. Car electrical systems that could cause the headlights to unexpectedly completely fail WHILE DRIVING are a recall-worthy safety issue. The inability to control the HVAC/defroster isn’t generally a recall-worthy safety issue. Even if such controls fail while driving, you have more than enough time to pull over safely. Same with windshield wiper motors that fail. There’s a difference between component failure and unexpected or intermittent failure of the complete system that could cause a crash. A backup camera failure isn’t generally an emergent safety issue generally worthy of a recall. You’ll always know the backup cam isn’t working before you even start to back up, and can choose not to if you can’t do so safely. IMO the best possibility for this to be considered a recall-worthy safety issue is the turn signals not working. Everything else is pretty minor and doesn’t create an emergent, unexpected safety issue while driving.
