2007 Jeep Wrangler

The National Highway Traffic Safety Administration is investigating owner complaints about Jeep Wrangler and Nissan Altima vehicles. The government agency is looking into 29 consumer complaints for airbag problems on 2007 and 2008 Jeep Wrangler SUVs and 20 complaints for brake problems on 2007 and 2008 Nissan Altima cars.

The 29 Jeep Wrangler complaints the agency received were for airbag warning lights illuminating, The Wall Street Journal’s Driver’s Seat blog reports. The agency says 23 of the 29 Wrangler complaints reported that the airbag clockspring wiring assembly was the source of the problem. A problem with the airbag’s electrical circuit could cause the driver’s side front airbag not to inflate in an accident. About 222,500 Jeep Wranglers are being investigated by the NHTSA.

2007 Nissan Altima

The federal agency is also investigating 440,000 Nissan Altimas for braking problems, The Detroit News reports. The agency has received 20 complaints for potential brake master cylinder leakage. Some of the complaints stated that “brake fluid leaked into the brake booster assembly.” Two complaints report that the brakes weren’t as effective, while the remaining 18 complaints reported only an illumination of the brake warning light.

In July 2008, Nissan recalled 169,000 Sentra cars from the 2007 to 2008 model years to fix a similar problem with “the brake master cylinder that could result in brake fluid slowly leaking from the master cylinder into the brake booster assembly,” according to The Detroit News. In October 2009, 10,586 more 2008 Sentra cars were added to the recall.

"Nissan is committed to customer safety and the quick, effective resolution of safety issues and will work closely with NHTSA to investigate this issue,” Nissan Spokesman Colin Price told The Detroit News. “While we are aware of several customer complaints made directly to NHTSA related to this issue, we are not aware of any accidents or injuries related to this investigation."

We’ll let you know if these investigations lead to vehicle recalls.
