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 Chevy Volt will be 2016 model and ride on new chassis

What do we know about the 2016 Chevy Volt? Well, for now, all we can do is try to put the puzzle together without the box. Thankfully, a new batch of pieces has arrived from a new report in Edmunds, which says that the 2016 model year will introduce the second generation of a car that hasn't been dramatically updated since it went on sale in 2010. The new Volt is getting an "evolutionary styling change" and will ride on a new front-drive platform that has been developed by General Motors. GM's Kevin Kelly told AutoblogGreen that he has "no comment on future products," but he did acknowledge that Chevrolet is working on a second-generation Volt, "but I can't say anything about timing." Everybody already knew that a next-gen Volt is coming, so that's not a surprise. What we don't know is any real concrete information on the car itself. The few tidbits of information we do have help define the outlines of the next version of Chevy's halo car, but they're not confirmed yet. For the record, they range from the eye-raising (a $10,000 price drop) to the logical (20 percent more electric range). We can't see the whole picture yet, but the pieces do point to the 2016 Volt, which would be released next year sometime, being a much bigger deal than the last update, when the Volt's range was increased by three electric miles thanks to a battery capacity increase of 16 kWh to 16.5.

Buick Encore, Chevy Trax earn Top Safety Pick from IIHS [w/video]

The Buick Encore has been a massive sales success practically from the moment it debuted, and Buick recently decided to increase production to keep up with demand for the premium compact crossover. The Insurance Institute for Highway Safety recently put one to the test again, and the Encore earned a Top Safety Pick award. It's the first model from the brand to score the nod since 2013, according to the IIHS, and the rating also carries over to the 2015 Chevrolet Trax. The 2015 Encore scored a Good rating in all of the IIHS' evaluations, including the 40-mile-per-hour, small overlap front crash test. That was a big improvement over the previous model the institute tested, which scored a Poor result in the overlap test. In the first test, about 13 inches of the lower door hinge pillar came into the passenger compartment, and the steering wheel airbag moved too far to protect the dummy's head. Improvements for the latest model year showed six inches of intrusion this time, and the airbags caught the dummy's head well. The dummy's sensors also indicated a low risk of injury. The two CUVs missed out on the full Top Safety Pick+ because the IIHS scored the Encore as only having a basic front crash prevention system, and there was no such equipment for the Trax. To earn the highest mark, models need at least an advanced rating by the institute for this technology. Buick Encore, Chevrolet Trax earn 2015 TOP SAFETY PICK award ARLINGTON, Va. - A small SUV is the first vehicle from the Buick brand to qualify for a TOP SAFETY PICK award from the Insurance Institute for Highway Safety since 2013. The Buick Encore's newly introduced, lower-priced twin, the Chevrolet Trax, also qualifies for the honor. The Encore's award follows improvements to the SUV's structure for better small overlap front protection. The 2015 model earns a good rating in the small overlap test. In contrast, the 2013-14 Encore rated poor in the test. The driver's space was seriously compromised with intrusion measuring as much as 13 inches at the lower door hinge pillar. The dummy's head barely contacted the front airbag before sliding off the left side, as the steering column moved to the right. The side curtain airbag deployed too late and didn't have sufficient forward coverage to protect the head. In the latest test, the driver space was maintained reasonably well, with maximum intrusion of 6 inches at the door hinge pillar and instrument panel. The dummy's movement was well-controlled.
