Seems like there are a number of issues with this.

1. Not defining “reliability challenge” in a meaningful way. (How many of these are problems that are expensive or time-consuming to repair? How expensive and how time-consuming? Are these problems that prevent the car from driving safely, or are they inconveniences that can be put off?)

2. Not controlling for manufacturer. (Toyota has long-been regarded as a reliable manufacturer, but they make 2 plug-in hybrids and 1 EV, all of which are new this year. Meanwhile, they offer about a dozen different traditional hybrids. I can believe that the Tesla Model 3 is less reliable than the Toyota Camry, but is a full-electric Hyundai Ioniq less reliable than a Hyundai Sonata?)

3. Including plug-in hybrids and full electric vehicles as one category. (Plug-in hybrids combine the old breakable parts such as transmissions with the new breakable parts such as lithium batteries. This is the trade-off that buyers make to get the efficiency of an electric vehicle at short ranges and the convenience of an ICE at long ranges.)

Important to note that this is a workaround. Solidarity strikes (which normally include general strikes) are illegal, but there’s no law that prevents every union from happening to strike on their own behalf at the same time.

American unions are kneecapped by the government. The 1947 Taft-Hartley Act made solidarity strikes (and several other forms of labor protest) illegal. It also opened the door for states to enact “right-to-work” laws.

This law is still standing in part because US courts have been anti-labor for their entire existence, aside from a brief period during FDR’s administration.
