GM-Isuzu joint venture assembles 1.5-millionth Duramax diesel

General Motors and Isuzu have officially stitched together 1.5 million Duramax 6.6-liter diesel engines. The joint venture between the two manufacturers started in 1998, and now the DMAX plant employs 517 workers in a 584,000 square-foot facility. GM introduced the Duramax turbo diesel engine to the US market for the 2001 model year, and it can be found trucks like the Chevrolet Silverado HD and GMC Sierra HD as well as the full-size Chevrolet Express and GMC Savana vans. In its current configuration, the engine yields 397 horsepower and 765 pound-feet of torque at just 1,600 rpm.
Of course, the big oil burner has plenty of tuning potential as well. As you may recall, a Duramax-powered truck recently set the land speed record for towing a vehicle at 142 miles per hour.
GM owns 60 percent of the joint venture, with Isuzu laying claim to the remaining 40 percent. The facility is located in Chicago. You can take a look at the brief press release below for more information on the milestone.

GM recalling 250,000 SUVs over door electronics

After a door-fire investigation that dates back to February, the National Highway Traffic Safety Administration has officially announced a recall today that affects around 250,000 General Motors SUVs for a faulty driver's door module. The recall applies to the Buick Rainier, Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X from the 2006 and 2007 model years, as well as the 2006 Chevrolet Trailblazer EXT and GMC Envoy XL for vehicles sold and/or registered in the Snow Belt.
Road salt use in these midwestern and northern states can lead to corrosion of the driver's door module on these GMT360 and GMT370 vehicles, which allows water to come in contact with the circuit board. If shorted out, the vehicle's power door locks and power windows will not work, and could possibly lead to overheating and, in some circumstances, a fire. No official word on how many total vehicles caught on fire, but back in June, 28 fires had been reported to the government agency. A fix for the problem is still being worked out, but all affected vehicle owners will be notified by GM.

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.
