It may actually be the case in the US. The problem is it's really hard to take something like this to court.
For starters, the arbitration clause is designed to make sure that these cases never get to the supreme court. Lower courts see an arbitration clause and say "Thank god, I don't want to deal with this" and are more than happy to sweep cases that way to unload their docket. Once in arbitration, any ruling made has no precedent setting value. The arbitration process is itself designed to drive up legal costs.
But even if that arbitration clause wasn't there or a judge decides to hear the case, it's incredibly expensive to take someone to court. Hundreds if not millions of dollars in fees. The US doesn't have a "loser pay" system, instead both sides are responsible for their own legal fees. Further, the US doesn't have any sort of public civil litigators. We barely have criminal defenders.
The best case scenario is that some sort of class action is built up. But that's really hard and isn't likely to address the contract itself. Even if it does, it'll only be the one contract for the one manufacturer.
Big legal fees, limited applicability, likely burden shifting from public courts. The only way this gets addressed would be through regulation or new laws outlawing the practice.
