The National Highway Traffic Safety Administration (NHTSA) has been investigating General Motors (GM) due to a 2015 headlamp driver module recall that was meant to fix faulty low-beam headlights. NHTSA is looking into whether or not the 2015 recall fixed the affected vehicles and if enough vehicles were included after receiving numerous consumer complaints.
Approximately 318,000 cars may be affected. Vehicles listed in the original recall include the 2005-2009 Buick LaCrosse, 2006-2007 Buick Rainier, 2006-2007 Chevy TrailBlazer, 2006 Chevy TrailBlazer EXT, 2006-2007 GMC Envoy, 2006 GMC Envoy XL, 2006-2008 Isuzu Ascender, 2007 Pontiac Grand Prix and 2006-2008 Saab 9-7X.
The company states that, in the affected vehicles, the headlamp driver module may overheat, which could melt the module under the hood and result in failing headlight and daytime running lights.
Since the 2015 recall, nearly 130 consumers filed complaints with NHTSA against GM for the same problem the recall was supposed to fix. Owners of affected vehicles allege that the replacement parts they received had the same issue as the original.
Other owners claim their GM vehicles had lost low-beam headlights several times, but were denied repairs because the vehicle identification number wasn’t included in the original recall.
