Chevy Colorado configurator goes live as GM touts fuel efficiency

While the news of today is destined to be dominated by a certain plucky Japanese roadster, props to Chevrolet and GMC for announcing its own significant bit of news about their newest pickup twins, the midsize Colorado and Canyon. The two GM-owned brands announced that the twins' 3.6-liter V6 will return up to 26 miles per gallon on the freeway.
To get such efficiency from the 305-horsepower mill, you'll need to live without four-wheel drive and be okay with a max city fuel economy of 18 mpg. The combined rating for the 2WD model sits at 21 mpg. Adding four-wheel drive drops the city and combined ratings by one mpg, while the highway rating dips from 26 to 24 mpg.
As for the twins' eagerly anticipated 2.8-liter diesel engine, it's destined for model year 2016, meaning we've got a ways to go before its efficiency and output are certified.

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.

New J.D. Power Initial Quality Study puts Porsche, GM in spotlight

J.D. Power and Associates has released its annual Initial Quality Study, and this year, Porsche and General Motors took the spotlight. The study, which asks new car owners to report problems experienced during the first 90 days of ownership, found that overall, the industry averages 113 problems per 100 vehicles.
Porsche managed a score of just 80 problems per 100 vehicles, while GMC took the second spot on the podium with 90. Lexus filled out the top three with 94 problems per 100 vehicles, followed by Infiniti at 95 and Chevrolet at 97. The study also looks at specific models, and found the Lexus LS to enjoy the best initial quality at 59 problems per 100 vehicles.
Interestingly enough, the report found that around two-thirds of most owner problems experienced in the first 90 days are attributable to vehicle design instead of mechanical failure. Specifically - echoing a refrain we've been hearing for the last few years - owners are having a hard time figuring out how to use the technology present in their new vehicles. Head over to the J.D.
