6 million GM light trucks being studied by NHTSA for corroded brakes

Around 6 million General Motors light pickup trucks and SUVs are under federal investigation for possible brake-line failure that can be caused by corrosion. The National Highway Traffic Safety Administration said its first stage of formal investigation covers Chevrolet Silverados, Avalanches, Suburbans and GMC Sierras, Tahoes and Yukons from the 1999 to 2003 model years.

NHTSA said that it received 110 owner complaints of “loss of breaking effectiveness,” 37 of which were confirmed by dealers. Three of the complaints allege that corroded brake line failure led to crashes.

In addition to the light pickup trucks, the NHTSA is also investigating 189,000 heavy-duty pickups for the same problem.
