As federal regulators shared an update about the availability of parts to repair vehicles with faulty ignitions, General Motors announced its 79th recall of the year this week, detailing a campaign for more than 300,000 older sedans and SUVs because of a problem with their headlamps.

The affected models for possible intermittent or permanent loss of low beam headlamps include:

— 2006-2009 Buick LaCrosse
— 2006-2007 Chevrolet TrailBlazer and 2006 TrailBlazer EXT
— 2006-2007 GMC Envoy and 2006 Envoy XL
— 2006-2007 Buick Rainier
— 2006-2008 Saab 9-7X
— 2006-2008 Isuzu Ascender

“If the headlamp driver modules is not operating correctly, the low-beam headlamps and daytime running lamps could intermittently or permanently fail to illuminate,” GM spokesperson Alan Adler said in an email message. “This condition does not affect the high-beam headlamps, marker lamps, turn signals, or fog lamps.

“GM has not been able to confirm whether the HDMs in these vehicles caused any vehicle accidents,” Adler added.

The automaker indicated there are 273,182 units in the U.S. associated with this recall, and this campaign covers a total of 316,357 vehicles, including units in Canada, Mexico and exports from North America.

So far this year, the OEM has recalled 26,849,925 vehicles in the U.S. and 30,413,023 units worldwide.

NHTSA: Parts Available to Fix Faulty Ignitions

In related news, GM told the National Highway Traffic Safety Administration on Tuesday that the OEM has enough parts are available to fix all the faulty ignition switches that are covered by its recent recall of more than 2 million vehicles. NHTSA urges owners of unrepaired GM vehicles to immediately contact their local dealer to arrange a service appointment.

GM emphasized that many franchised dealers will help owners get their vehicles remedied after work and on the weekends.

Regulators contend there are nearly 1 million vehicles with these faulty ignition switches still in the vehicle, creating a danger of the airbags not deploying in the event of a crash. The involved vehicles are

— 2003-2007 Saturn ION
— 2005-2010 Chevrolet Cobalt
— 2006-2011 Chevrolet HHR
— 2007-2010 Pontiac G5
— 2006-2010 Pontiac Solstice
— 2007-2010 Saturn Sky.

Owners can also confirm whether their individual vehicle needs to be repaired under this recall or any other GM recall by using NHTSA’s free VIN look-up tool on safercar.gov.

At NHTSA’s direction, regulators indicated GM ramped up its production of replacement ignition switches in order to complete production of replacement parts ahead of its original goal of early November.

NHTSA also pushed the automaker to take steps to maximize the number of vehicle owners who bring in their vehicles for repair, including targeted outreach to non-English speakers, maintaining up-to-date information on its website as required by the consent order, and a combination of traditional and social media outreach, financial or other incentives, phone calls, and other approaches.

Consequently, the agency said GM has repaired nearly 60 percent of the affected vehicle population covered under the recall, but many others remain.

“Moving forward, NHTSA will continue to push the automaker to keep up the momentum and get the remaining vehicles fixed promptly,” officials said.

NHTSA went on to note that vehicle owners should contact their local dealers immediately to schedule an appointment to get the final remedy. Until the affected vehicle is fixed, owners should follow all of the interim safety steps advised by GM and keep in mind that the use of a single key is not a long term solution to the this serious safety problem.
