NHTSA, fresh off its $16 million smackdown on Toyota is now investigating the company that booted Toyota from Consumerist’s Worst Company In America tournament — General Motor — for possible brake failure issues in millions of the company’s trucks and SUVs.

According to an announcement from NHTSA, the defect involves potential brake line rupture in Chevy and GMC C/K series pickups and SUVs for model years 1999 through 2003. That is a total of around 6 million vehicles.

NHTSA says is has received 110 complaints, which include 3 crashes, regarding an alleged loss of braking effectiveness.

In their words now:

The complaints allege the loss of braking effectiveness due to brake line rupture because of corrosion. In 37 of these complaints, the brake line failure was confirmed by a dealer inspection.

FYI, right now GM is losing to Anthem BCBS in the Sweet 16 of Worst Company In America.
