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.

Buick confirms US-market Envision CUV to be built in China

As expected, the Buick Envision will come to the US market in 2016, and as rumored, it'll be GM's first product imported from the People's Republic. Buick confirmed the news today, while also releasing a number of technical details on the mid-size CUV, which has sold nearly 130,000 units in the Chinese domestic market in the first 11 months of 2015. When it arrives in US dealers next summer, the Envision will feature a 2.0-liter, turbocharged four-cylinder EcoTec four-cylinder. Good for an estimated 252 horsepower and 260 pound-feet of torque, the four-pot turbo is paired to a well-received six-speed Hydra-Matic 6T70 transmission. That's the same automatic gearbox that's offered in the turbocharged Regal and Regal GS and the current six-cylinder LaCrosse. The entire affair is underpinned by torque-steer-fighting HiPer strut front suspension, a crossover first for Buick, with a four-link setup in back. According to Buick, the Envision will also get the same Active Twin Clutch all-wheel-drive system being offered on the Cadillac XT5 and the new LaCrosse. Like the Chinese-market Envision, Buick is offering the USDM model with active grille shutters, LED running lights, LED taillights, heated front/rear seats, a heated steering wheel, 19-inch wheels, and a Bose stereo as standard. Buick also lists highlights like Active Noise Cancellation and an eight-inch IntelliLink infotainment system, although it's not clear whether these are standard features. There's no word on which auto show the Envision will debut at. Considering the timing, next month's Detroit Auto Show is a strong contender, although if Buick wanted to really drum up headlines ahead of its on-sale date next summer, it'd formally introduce its newest CUV in April, at the New York Auto Show. Either way, expect to see more of this handsome, Chinese-built CUV soon.

It was awarded Motor Trend SUV of the Year in China and has 127,085 sales so far this year. When it goes on sale in 2016, it will play an important role in a crossover lineup that currently represents 60 percent of Buick sales in North America. It targets customers shopping between the Encore, the best-selling Buick in eight years, and the Enclave, which has continued to grow its customer base since its 2007 introduction.

GM throttles back Chevy Malibu, Buick LaCrosse production over swollen inventories

As inventory of the Chevrolet Malibu and Buick LaCrosse continues to pile up, General Motors will be idling its Fairfax Assembly Plant for two weeks, according to Automotive News. This move comes about a month after the plant was shut down for three weeks in late December and early January for the same reason. As of January 31, the GM had a 94-day supply of Malibu stock while the LaCrosse was a little worse with a 117-day supply.
Just last week, GM announced that it would be investing $600 million in upgrading this plant, but it's unclear what future plans the company has in store for Fairfax considering slow sales of both the plant's models. We do expect a refreshed and more luxurious LaCrosse shortly and an early design update for the Malibu to be announced at some point this year, although we have had no official word as to when either will happen.
