GM Recalling More than 26,000 Cadillac, Chevrolet and GMC SUVs and Trucks

General Motors is expanding a previous recall concerning a faulty rear-axle cross pin to include another 26,751 SUVs and trucks from the 2011 model year. The first recall was issued in late December and concerned approximately 1,260 Cadillac Escalades, Chevrolet Avalanche and Silverado 1500s, and GMC Sierra 1500s, all from the 2011MY.

The updated recall now covers certain 2011MY Cadillac Escalade, Escalade ESV, Escalade EXT; Chevrolet Avalanche, Colorado, Silverado, Suburban, Tahoe; and GMC Canyon, Sierra, Yukon and Yukon XL vehicles.

The Detroit automaker said the rear axle cross pins were not properly heat treated and could fracture and become displaced within the rear axle.

"Should the pin shift out of position, it could create an interference condition and cause the rear axle to lock. The driver may not be able to maintain directional control of the vehicle and a crash could occur without warning," said GM in a statement on NHTSA's website.

As expected, GM's dealers will install a new rear axle cross pin free of charge, with the safety recall to begin before the end of the month

GMC Shows More of its Detroit-Bound Sierra All Terrain HD Concept

We first reported on the new GMC Sierra All Terrain HD Concept in mid-December, but since then, General Motors has released a slew of new photos. The updated gallery includes the first photos of the design study's interior that has been spruced up with higher quality and more luxurious materials than the standard Sierra, upon which it is based.

Set to debut at next week's North American International Auto Show, GMC says the concept model is an exploration of heavy-duty truck capability combined with greater off-road versatility. Even if the Sierra All Terrain HD Concept doesn't make it as is onto the road, chances are that it will inspire a future production version. Full HD gallery after the break.

GM Issues Separate Recalls on Cadillac CTS and Escalade, and Chevy and GMC Trucks

General Motors is recalling close to 100,000 vehicles in two separate campaigns. In a posting with the U.S. National Highway Traffic Safety Administration [NHTSA], GM said the first recall affects almost 96,000 Cadillac CTS sedans from the 2005-2007 model years over concerns that some of the vehicles have a condition in which repeated flexing of the passenger sensing system mat in the passenger seat may break the connection. The company said that if this occurs, the sensor may not detect the presence of a front seat passenger and will disable the air bag.

Dealers will replace the passenger sensing system free of charge, however, GM has yet to provide an owner notification schedule for the CTS recall.

The second recall from GM concerns approximately 1,260 Cadillac Escalades, Chevrolet Avalanche and Silverado 1500s, and GMC Sierra 1500s, all from the 2011 model year. These trucks may have a faulty rear-axle cross pin, which could fracture and become displaced within the axle.

GM said that if the pin shifts out of position, it could create an interference condition and cause the rear axle to lock, in which case, the driver may not be able to maintain directional control of the vehicle and a crash could occur without prior warning.

The company added that this safety recall is expected to begin during January 2011.

GMC Previews Sierra All Terrain HD Concept Ahead of Detroit Show

General Motors will be presenting an ultra-tough concept study based on the four-door 2011 GMC Sierra HD pickup truck at the rapidly approaching Detroit Motor Show in mid-January. The GMC Sierra All Terrain HD study is highlighted by its rough n' tough exterior design and enhanced all-road capability.

Shorter in overall length than production Sierra HD models, the concept boasts a unique five-foot, eight-inch Crew Cab/short box body configuration with the wheels pushed to corners of the vehicle.

It also features a wider, 73-inch (1,853 mm) track for greater stability and approximately 3 inches (76 mm) greater ground clearance for a total of 21.1 inches (536 mm) at the rockers and 11.8 inches (300 mm) at the skid plates.

To improve its off-road prowess, GMC retuned and upgraded the suspension with specialized Fox off-road shocks, while the All Terrain HD also features electronic disconnection of the front stabilizer bar at the push of a button. The 20-inch alloy wheels wrapped in 35-inch-tall BFGoodrich mud terrain tires and the full composite underbody protection that shields the transmission, drivetrain, fuel tank, exhaust system and axle differentials, round off the package.

Motivation comes from GM's new production 6.6-liter Duramax turbo-diesel V8 that delivers 397 horsepower and 765 lb.-ft. of torque (1,037 Nm), and is matched to a six-speed auto.

The concept also features four-wheel drive, with automatic locking front and rear differentials, and 14-inch, four-wheel disc brake system from the production Sierra HD.

General Motors did not say if it has plans to develop a production version of the concept, but given that it is based on the 2011 Sierra HD, we wouldn't be surprised if the automaker launched a similarly flavored variant in the near future.
