GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

2013 Buick Encore nets strong IIHS, NHTSA safety scores

After being crushed from every which way and rolled over like a labrador, the 2013 Buick Encore has been named a Top Safety Pick by the Insurance Institute for Highway Safety. To earn the accolade, a vehicle must achieve the highest rating of "Good" in each of the institute's four main crash tests: Front Moderate Overlap, Side, Rollover and Rear. The Encore aced those four tests with "Good" ratings, but missed out on the coveted Top Safety Pick+ designation by receiving a Poor rating in the institute's new Front Small Overlap test. To be named a Top Safety Pick+, the Encore would need to score at least an "Acceptable" rating in the new test, as well as "Good" in all four original crash tests.
Despite the miss, the Encore joins the Enclave, LaCrosse, Verano and Regal as Top Safety Picks all. If you count only the Encore with all-wheel drive, then all five Buicks have also earned five-star overall ratings from the National Highway Traffic Safety Adminstration, making Buick one of the few manufacturers to offer a full lineup with high scores from both safety rating organizations.
The front-wheel-drive Encore, despite performing equally as well as the all-wheel-drive version in NHTSA's crash tests, only earned four stars overall. As far as we can tell, the discrepancy between the two is because some safety equipment, like Forward Collision Warning and Lane Departure Assist, are optional features on the FWD Encore and standard on the AWD model.

Movie Review: Black Air: The Buick Grand National Documentary

As Buick currently claws and scratches its way back into relevance to compete against luxury brands like Lexus and Acura, it's hard to believe that not too long ago, the brand had a car that was mentioned in the same breath as Corvette, Lamborghini and Ferrari. That car? None other than the Buick Grand National. All black with a turbocharged V6 and some of the quickest acceleration of its time, the Grand National, in today's standards, is along the lines of a 2013 Shelby GT500 with both cars essentially being a working man's supercar.
The last Grand National rolled off the assembly line in Flint, MI on December 11, 1987, and to mark the silver anniversary of that somber occasion, Black Air is a documentary of the Grand National from the perspective of the enthusiast, the collector, the media and even from those at General Motors responsible for creating such a sinister legend. Like the car itself, Andrew Filippone Jr. shoots the documentary in a raw fashion, and it definitely helps to show why a low-volume muscle car from the 1980s is still the object of obsession for many automotive enthusiasts to this day.
