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.

How to hack a Buick Regal with CarKnow

If you own an Apple iPhone or Android device, perhaps you've been tempted to jailbreak or root it. This process gives you access to the the software's code, and can be used to make minor or drastic changes to its operating system. CarKnow, a company in Boston, is working applying a similar concept to the automobile.
Translogic recently took a look inside CarKnow to see just how it can tweak the computers inside a car and what sort of things can be done. As our transportation tech sister site explains, CarKnow basically created a digital duplicate of their Buick Regal in the cloud, while harvesting data generated to create custom apps and infiltrate the deepest function of their test car.
And before you freak out about people maliciously taking over your car, CarKnow's founder, Josh Siegel, stresses that it isn't quite so easy as driving up alongside someone. Take a look at the full video below to see just what it's like to jailbreak a car.

2014 Buick LaCrosse steps up to the big leagues with plenty of luxury

Following the introduction of the updated 2014 Buick LaCrosse and Regal, the oldest vehicle in Buick's lineup will be the Verano, which was just introduced last year. Having such a fresh product mix bodes well for Buick as it tries to create a new image in the US, and after checking out the amount of luxury being stuffed into the new LaCrosse for 2014, GM's awkwardly positioned brand may finally have the ability to stand out.
Granted, the model unveiled was the all-new, top-of-the-line Ultra Luxury Interior Package, but this package brings top-notch leather and soft suede covering everything above the beltline as well as real ash wood accent trim throughout the cabin. While there was no mention of price, we don't expect this model to come cheap in terms of what we expect from Buick, although it will likely be competitively priced with similarly equipped rivals like the Acura TL or Lexus ES. Adding even more to the LaCrosse's interior, dual eight-inch displays make up the gauge cluster and center stack, and the number of buttons on the center stack have been greatly reduced, creating a cleaner look for the instrument panel.
Another big change is the next-generation of Buick's IntelliLink infotainment system that brings with it all of the recent enhancements of the Cadillac CUE and Chevrolet MyLink systems. Differentiating itself from other GM infotainment systems, the new Buick IntelliLink stands out by allowing users to customize the apps they can add and not just being limited to what GM sees fit.
