The National Highway Traffic Safety Administration is investigating Chevrolet and GMC pickup trucks and sport-utility vehicles for possible brake failure, Bloomberg News reported.
NHTSA said it has received complaints about loss of braking effectiveness due to brake lines that rupture because of corrosion. The agency has received 110 complaints about a loss of braking effectiveness, including three crashes, involving the vehicles. In 37 of those cases, a brake line failure was confirmed by a dealer inspection, Bloomberg said.
The defect may affect 6 million Chevrolet and GMC C/K series pickups and SUVs for the 1999 through 2003 model years.
General Motors did not immediately respond to a request for comments, Bloomberg said.
