General Motors has announced that it has incorporated the Duramax 2.8 liter turbo diesel engine in to its 2016 Chevrolet and GMC Canyon trucks. In addition, General Motors has announced that the EPA has certified the trucks for getting 31 mpg on the highway. On November 17, Engineering News Record reported that the engine is a four cylinder diesel and generates 181 horsepower and 369 foot pounds of torque. In addition, two wheel drive vehicles equipped with six speed transmissions will get EPA estimated mileage rates of 22 mpg in the city and 25 mpg in combined driving. For those interested in four wheel drive vehicles, the mileage rates are 20 mpg in the city, 29 mpg on the highway and 23 mpg in combined driving.
Duramax was created in 1998 as a result of a joint venture between General Motors and Isuzu to manufacture diesel engines. Specifically, the goal was to manufacture the first high pressure, common rail, direct injection engine. Prior to the Duramax engine, GM used an engine that was made entirely of iron in a V-8 configuration, was of the indirect injection type, took up 6.5 liter, rated at 215 horsepower and 440 foot pounds of torque. For the most part, GM began installing 6.6 liter diesel engines in some of the full size pickups back in 2001. As the demand evolved, so did the engine. From 2001 until the present, there have been 5 variations until now when the 2.8 liter engine has been introduced into the midsize truck range.

Recently, some major manufacturers have recalled some of their vehicles for some serious defects. First, General Motors has recalled 1.4 million of its vehicles for an oil leak that can result in an engine fire. This particular recall is also part of a series of recalls for this same problem; that were initiated in 2008. At one time, the problem was thought to have been caused by leaky valve cover gaskets. Currently, GM is saying that drops of oil can be deposited on a hot exhaust manifold and ignite. But, GM is not saying what the source of the oil is; only that they are working on a repair. The vehicles that are involved in this recall are:
1997-2004 Pontiac Grand Prix
2000-2004 Chevrolet Impala
1998-1999 Chevrolet Lumina
1998-2004 Chevrolet Monte Carlo
1998-1999 Oldsmobile Intrigue
1997-2004 Buick Regal
All of the above vehicles are equipped with 3.8 liter, V6 engines. Owners should take their vehicles to their GM dealerships for repair. For additional information, owners can contact GM by calling 1-800-222-1020 for Chevrolet vehicles, 1-800-762-2737 for Pontiac, and 1-800-521-7300 for Buick.
Second, GM isn’t the only car maker with problems. Nissan is recalling 46,846 model year 2013-2016 Altimas and 2016 Maximas. This is in addition to the already recalled 5,500 model year 2016 Maximas. These vehicles are all equipped with 3.5 liter, V6 engines. The problem with these vehicles is that an O-ring installed between the fuel tank and fuel sending unit was improperly installed and can leak in the event of a crash. Fuel in the presence of an ignition source can result in a fire. Nissan has already begun notifying owners. Owners should take their vehicles to a Nissan dealer for a free repair. For additional information, owners can contact Nissan at 1-800-647-7261.
Third, BMW is recalling approximately 86,000 Mini hatchbacks for a steering problem. The vehicles that are involved are 2002-2005 Mini Cooper, Cooper S, and 2005 Cooper and Cooper S convertibles. These vehicles can lose their electro-hydraulic power steering assist and as a result, drivers can find it more difficult to control the vehicle. It is possible for a crash to occur if the driver cannot apply the extra effort required to steer the vehicle and maintain control. Mini will begin notifying owners on or about December 1, 2015. Mini dealers will also inspect and replace components as necessary free of charge. For additional information, owners can contact MINI customer service by calling 1-866-825-1525.

An announcement was made this past week whereby General Motors would pay out 900 million dollars as a result of the ignition key switch defect that has cost the lives of over 100 people. On the other hand, the owner of the Peanut Corporation of America has been found guilty and is facing a prison term that could amount to life in prison for the deaths of nine people. If you will recall, this was the same company that knowingly distributed peanuts for use in food products consumed by both people and animals tainted with salmonella bacteria. When the two cases are compared, how is it that the deaths of nine people rate the imprisonment of the company owner when the deaths of over 100 require only a monetary payment from the company and no prison time for any of the company’s senior management?
