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.

GM applies to trademark Buick's Electra name in Canada

At Auto China 2020 in Beijing, Buick revealed an Electra concept with a design language called Potential Energy created by one of GM's Shanghai-based design studios. A press release about the concept said the "all-electric crossover offers a sneak peek at Buick’s vision for a new intelligent electric future." It's possible that the "intelligent electric future" could include the Electra name, as the Rivian Owners Forum discovered Buick applied to trademark that model name in Canada on December 20. Buick isn't new to the name, having put it on a luxury sedan it produced from 1959 to 1990. What better way to resurrect history with electricity using the name Electra and a design language called Potential Energy? As the Rivian forum also noted, Buick snuck a concept car into General Motors' promotional video for the Ultifi software platform that will connect owners' digital lives across vehicles and locations. For less than two seconds at the end of the vid, a seriously chic fastback sedan speeds through a digital landscape, a Buick tri-shield logo set into what looks like an active rear spoiler. We don't see Buick building this car, but we'd love it if Buick did. What we imagine more likely is a more production-possible evolution of the Electra concept shown in Beijing last year that had Ultium batteries powering two electric motors that shared a combined 583 horsepower among both axles. The sprint to 60 miles per hour was said to take 4.3 seconds, range estimated at about 410 miles. The dihedral doors enclosed a buttonless cockpit with a rectangular, retracting steering wheel, huge curved screen, eConnect software, and an AI-powered assistant for feature control. There was also a skateboard tucked into the rear bumper for last-mile travel to the destination or the half-pipe. We expect Buick to launch at least one crossover in 2024, and another in 2025. One of them will likely compete with the Ford Mustang Mach-E and the production version of the Chrysler Airflow concept. Related video:

Buick confirms 2017 Encore for New York Auto Show

Buick will unveil the refreshed 2017 Encore at the New York Auto Show in March, company spokesperson Stuart Fowle tells Autoblog. The brand isn't ready to divulge info about the updated compact crossover, but a recent revision to the Encore's European platform-mate, the Opel Mokka (above), might provide hints about what to expect. "While we have no additional details to announce, we're excited to confirm that media and customers will see the new 2017 Encore at next month's New York Auto Show. The Encore joins the Cascada convertible, Envision crossover, and LaCrosse sedan as the fourth new product arriving in Buick showrooms this year," Fowle said to Autoblog. Expect the 2017 Encore to have its own twist on the the Mokka's (now called the Mokka X) exterior styling, and spy shots hint the Buick has a new front end with a smaller grille. The Encore could benefit from the Opel's redesigned dashboard, which integrates the infotainment system into the center stack. It's a very attractive change, and we hope to see the switch in the US. The Mokka X also gets improved safety tech. The German compact CUV now sports adaptive LED headlights that adjust to traffic. US law doesn't allow these intelligent parts, but the Encore might get dumber LED lights. The Opel's improved front-mounted camera also increases the traffic sign detection rate. The Mokka X is available with the updated powertrain from the Encore Sport Touring, so there might not be any engine upgrades for the Buick. Buick needs to keep the Encore fresh, as the compact CUV is the brand's best selling model. It delivered 67,549 of them in 2015, a 38.2-percent jump over the previous year. The popularity continued into January 2016 with 4,920 deliveries – up 42 percent. Related Video:
