The Biden administration is cracking down on manufacturers that place heavy restrictions on who can do repairs—voiding warranties, for instance, if work is not done by an authorized dealer.

Many legal departments have lots of decisions to make to avoid ending up in regulators’ sights, legal observers say. They expect the Federal Trade Commission to unleash additional regulatory actions along the lines of a settlement it reached with Harley-Davidson last month forcing it to back away from warranty terms that voided coverage if customers used anyone other than the company or its authorized dealers for repairs.
