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.

Chevy gets cracking on Cruze EV fleet testing

The Chevrolet Volt hasn't yet gone on sale, but General Motors is looking at ways of expanding its electric vehicle lineup. Chevy, along with partner LG, is employing a group of all-electric cars in the form of the Cruze. The sedans are part of a demonstration fleet which is located in Seoul, South Korea and is being used to provide data in an electric vehicle research project. The goal is to gather information on driving patterns and charging behavior in addition to consumer acceptance.
The Cruze EVs, along with some Daewoo Lacetti Premieres EVs, are the first fleet of full-size electric vehicles and should provide invaluable information for The General. Staying full-size means not sacrificing cargo space, so the battery pack is mounted to the underbody, leaving the trunk area open for plenty recyclable, canvas grocery bags.

2014 Chevrolet Silverado and GMC Sierra show all their sides in Detroit

There could hardly be more riding on the next-generation General Motors full-size pickup trucks, so the automaker has wisely made sure to have a selection of different models on hand at the Detroit Auto Show to show off. The 2014 Chevrolet Silverado and 2014 GMC Sierra were both officially introduced last month at a stand-alone reveal, and now they'll be on display for the public to see in various body configurations and trim levels.
The Silverado LTZ Crew Cab and Sierra SLE Extended Cab are aimed at providing more of a high-end pickup experience, while the Silverado LT Z71 Extended Cab and Sierra SLT Z71 Crew Cab should have off-road fans scouting out their favorite trails. The crew cab trucks won't go into production until sometime during the second quarter of this year - with other bodystyles coming later in the year - but we have plenty of live images from Detroit for you to enjoy.
