Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

A loose power cable connection may cause electrical arcing, which can increase the risk of a fire.

Daimler Trucks North America, LLC (DTNA) is recalling certain 2020-2022 Thomas Built EFX and HDX school buses.

The nut for the power cable stud on the alternator may not have been tightened properly, which can cause a loose cable connection.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
