If people reported this problem to the NHTSA, Honda basically could only choose whether or not to do the recall voluntarily.

Faulty rearview cameras are considered recall-worthy in the US, as they are a required safety feature for every new vehicle from May 2018 onwards.

For context, at the time of that rule being made, there were on average 210 fatalities and 15,000 injuries caused by backover crashes per year. Americans, with our love for big SUVs and trucks with terrible sight lines, basically made not having a functional backup camera into a risk for human harm.
