The National Highway Traffic Safety Administration announced today that it is investigating roughly 6.2 million fullsize General Motors trucks for issues related to brake line corrosion.
The investigations will focus on brake lines fitted to nearly 6 million 1999-2003 Chevrolet Silverado, Tahoe, Suburban, and Avalanche models, along with their GMC equivalents, the 1999-2003 Sierra, Yukon, and Yukon XL. Likewise, a separate inquiry, targeting 189,000 Silverado and Sierra HDs built in 2003, also pertains to brake line corrosion.
According to the agency, corroded brake lines could burst during application, possibly triggering a sudden loss in braking strength, increased pedal travel, and increased stopping distances. The NHTSA says it has received 107 owner complaints for this issue from owners of the light-duty trucks above, and only three from owners of the 2003 Silverado/ Sierra 2500 HD. In 37 instances, the brake line failure was confirmed by a dealer inspection.
Although both investigations are but days old (they were opened on March 30 and 29, respectively), GM says it knows of the investigation, and is working with NHTSA to address the issue.
“We are aware of it and we are cooperating,” spokesman Alan Adler told The Detroit News.
