GM recalls over 230,000 more Trailblazer-family SUVs over door electronics

Back in August, the National Highway Traffic Safety Administration announced a recall on the General Motors GMT360 SUVs (Buick Rainier, Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X) ranging from the 2005 to 2007 model years and the 2006 GMT370 SUVs (Chevrolet Trailblazer EXT and GMC Envoy XL) due to potential fires associated with the driver's door module. Initially limited to 250,000 units sold or registered in 20 Snow Belt states (and the District of Columbia), the recall has now been expanded to include an additional 193,000 of these SUVs in the US and, according to The Detroit News, 40,000 more sold outside the US, including Canada and Mexico.
Like the original recall, the issue is still a faulty driver's door module that can short out, which could lead to a fire. The Detroit News is reporting that, out of the 443,000 units being recalled, GM says that there were 58 fires that caused 11 minor injuries, and the expanded recall accounted for six fires and one injury. Despite the lower number of fires, the recall notice recommends that owners park their vehicles until the recall repairs has been performed.
On recalled units with functional modules, the repair consists of a protective coating being applied to the module, while vehicles with modules that are not working properly will have the driver's door module replaced. The official recall notice is posted below, and it includes contact information for customers of all five brands.

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

Last-ever Buick Grand National heads to Barrett-Jackson auction

This 1987 Buick Grand National brought the curtains down on a heap of General Motors history. When this black beauty rolled down the line at 5 p.m. on December 11, 1987, it represented the end of manufacturing at GM's Pontiac Assembly Plant after 60 years building cars. This was the last car to sit on GM's G-Body platform, having supported legendary names like Monte Carlo, Cutlass Supreme, and Regal. And this was the last-ever Buick Grand National, a big coupe that in just five years on the market had helped make the Buick Regal lineup an object of sincere lust among enthusiasts. Powered by a 3.8-liter turbocharged and intercooled 3.8-liter V6, the engine made 245 horsepower and 355 pound-feet of torque. The only car above it in the lineup was the exceptionally rare GNX, which made 276 hp and 360 lb-ft. The Buick Grand National is headed to the Barrett-Jackson auction block in Scottsdale next month.    Louisiana resident Bob Colvin bought this car from the factory. The Drive spoke to Colvin, who explained that then-GM President Roger Smith told him he could have the penultimate Grand National, but Buick planned to put the last car on display. When Colvin arrived at the plant, though, Colvin said the plant manager told him, "I'm running this plant and you've gone through the effort to be here. It will be a real celebration," and got him the last car made. As proof, a GM film crew followed the car down the line, plant workers and two GM execs signed various parts of the engine, including current GM President Mark Reuss. The car comes with all of the autographs and signage the autoworkers created to go with the car, as well as the original window sticker. Colvin and his wife built an addition onto their house to display the car. Save for a trip to the Buick Centennial Celebration in 2003, the Buick has lived in its special place all its life and has just 33 miles on the odometer. Behind the new-car plastic that shrouds the interior, the only flaw appears to be a tiny crack in the steering wheel center cap where a bolt might have been overtorqued. The car is being offered with no reserve, the pre-sale estimate landing right around the $500,000 mark. That would about double recent auction sales for low-mileage GNX's this year, but there's every reason to believe this car's one-of-one place in history could get auction paddles waving.
