The National Highway Traffic Safety Administration is beefing up its investigation into whether General Motors have adequately recalled its vehicles for a reported brake light problem. According to the agency, it is looking into whether G.M. should have recalled about 551,000 vehicles as opposed to the 8,000 vehicles it actually recalled.
The original recall of about 8,000 vehicles included 2005-2006 year models of G.M.'s Pontiac G6s. NHTSA issued its report identifying its investigation after receiving over 300 additional complaints involving later models years. Notably, this is the third time the agency has questioned the sufficiency of a G.M. recall.
The safety agency now says it has received 314 complaints. G.M. has also admitted that it has received 1,104 complaints, in addition to about 14,400 "potentially related warranty claims." At least one crash has been reported, although it apparently did not result in an injury.
The NHTSA has upgraded its investigation into an engineering analysis, which may end up resulting in additional model years being recalled.
The other G.M. recalls include a June recall of nearly 194,000 2005 to 2007 model year sport utility vehicles due to an electrical problem that posed a fire hazard. A similar recall of about 278,000 vehicles was issued last year, but only in certain states.
The vehicles subject to the recall include the 2006 Chevrolet Trailblazer EXT and GMC Envoy XL; the 2006-7 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Isuzu Ascender models and the 2005-7 Saab 9-7x.
Another G.M. recall subject to the NHTSA's investigation involved 2012 models of the Chevy Camaro, Cruze, and Sonic, and the Buick Verano. The NHTSA continues to look into whether about 400,000 vehicles instead of 6,900 should be subject to the recall due to an air bag problem.
