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.

Next-gen Chevy Volt will get 1.5-liter, four-cylinder engine

As General Motors gets ready to unveil the new Chevy Volt at the Detroit Auto Show in January, it's starting to reveal a few more details about the updated plug-in hybrid. Today should be fruitful on that front, thanks to an event GM is hosting today that focuses on the new Volt, and we've just had the first bit of new: a bigger engine is coming. Since the beginning, the Volt has used a 1.4-liter, four-cylinder engine as a range extender when the battery runs dry. The second-generation model will instead get a slightly larger 1.5-liter, four-cylinder engine that will be built in Flint, MI. That's a step up from the various engines that have been a part of the 2016 Volt's rumored mills, everything from a 1.0-liter or 1.2-liter three-cylinder to a 2.0-liter turbo. The confirmation about the new 1.5-liter powerplant was found in Automotive News, where we also heard again that GM is going to start building the new Volt's electric drive unit in Detroit, moving production up from Mexico. We will have more information on the 2016 Chevy Volt later today.

Chevy Gives World Series MVP Madison Bumgarner A Recalled Truck

Last night must have seemed like a dream come true for San Francisco Giants pitcher Madison Bumgarner. He helped his team win its third World Series Championship in four years, earned MVP status and was given a brand new 2015 Chevrolet Colorado. Bumgarner might want to hold off on taking a victory lap in his new truck however. The Colorado is currently under recall. General Motors issued a stop-delivery order earlier this month to fix the truck's air bag connectors, which were wired improperly during the manufacturing process. The faulty wiring can cause the system to deploy incorrectly. Only 138 customers have received their Chevrolet trucks, the rest were caught and repaired either in the plant or on their way to dealerships and show rooms. Recalls Chevrolet world series
