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 Silverado Midnight Edition, Custom ready to stand out in pickup line

Chevrolet spent its Chicago Auto Show introducing a pair of fullsize pickups that promise image-conscious buyers a truck experience that goes beyond the standard range, with the murdered-out Midnight Edition and the um, not murdered-out, Custom. Let's start with the Custom, which adds 20-inch alloys, as well as chrome bumpers, mirror caps and door handles to the Silverado LS. Available in both V6 and V8 varieties, and with the customer's choice of two- or four-wheel drive, the Silverado Custom is the decidedly mellower example of Chevy's special edition styling. The Midnight Edition, meanwhile, throws subtlety out the window with a menacing set of visual upgrades. Based on the Z71, the Midnight adds 18-inch wheels, a spray-in bedliner and unique Z71 and Bowtie badges, all in black, of course. The front and rear bumpers, headlamp bezels, tow hooks, mirror caps and door handles, are also finished in the stealthy shade. Check out our live images of both special edition trucks, and let us know what you think down in Comments.

Chevy monitors drivers' biometrics while experiencing new Corvette Stingray

We tell you about what a car is like to drive every day, remarking on throttle response, steering weight and feedback, squat, dive, brake fade and a dozen or more other factors of performance. What we can't tell you, though, is what the car does to us - how its performance impacts us, physically. That's what makes this video series from Chevrolet so darn cool.
The Bow-Tie brand rented out Spring Mountain Motorsports Ranch, got several (very) different individuals together, strapped a bunch of sensors to their bodies to record biometric data ranging from heart rate to respiration to brain activity, and then handed them keys to the new Chevrolet Corvette Stingray. The results are explained in a series of videos, devoted to each driver, showing how different people react to the Corvette's performance.
If, like your author, you're a nerd for medical science, this is going to be a fascinating set of videos. If not, it's still pretty cool to see how the body of someone with racing experience, like Gran Turismo creator Kazunori Yamauchi, reacts to tracking a car like the Corvette Stingray compared to the owner of legendary Detroit barbecue joint, Slows BBQ. Take a look below for all six videos from the series, or hop over to the Corvette Vimeo channel for the interactive experience, where you can see all the different metrics.
