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 announces $7 billion Michigan factory investment, most going to EVs

GM announced a $7 billion investment in Michigan manufacturing, much of which is earmarked for EV production. Four sites are included, but the key elements are a new battery cell plant in Lansing and the conversion of GM's existing Orion Township facility to expand production of the forthcoming Chevrolet Silverado EV and its GMC Sierra sibling.  GM says it is the largest investment announcement in company history and that it will create 4,000 new jobs. It also says 1,000 jobs will be retained. "We are building on the positive consumer response and reservations for our recent EV launches and debuts, including the GMC Hummer EV, Cadillac Lyriq, Chevrolet Equinox EV and Chevrolet Silverado EV," said GM CEO Mary Barra.  GM says the Orion expansion and new battery plant will support an increase in full-size electric truck production capacity to 600,000 units. This is in addition to the Factory ZERO facility in Detroit that will also be constructing the electric Silverado and Sierra.  The Orion Township factory current builds the Chevrolet Bolt EV and EUV, and will continue to do so during the plant's conversion. GM did not indicate what will happen with the Bolts once that conversion is complete or whether all will continue to be built at Orion. They do not use the Ultium vehicle architecture. GM will build other EV models at three other factories that are under construction or being converted. They are located in Spring Hill, Tennessee, Ingersoll, Ontario, and Ramos Arizpe, Mexico. GM says that it will have the ability to produce 1 million electric vehicles by 2025. The Ultium Cells Lansing facility is a $2.6 billion joint investment by GM and LG Energy Solution. GM says it alone will create 1,700 jobs once fully operational by late 2024. It will join two other GM Ultium Cells battery factories currently under construction in the United States, one in Ohio and the other in Tennessee.  Not all of the $7 billion investment will be for EVs. It also announced $510 million of the total will go toward upgrading the Lansing Delta Township Assembly to produce the next-generation Chevrolet Traverse and Buick Enclave. Money will also go to upgrading Lansing Grand River Assembly.

2022 Buick Encore starts at $25,795

The Buick Encore entered the market here for the 2013 model year, its combination of solid, practical, and premium-ish content working well enough to increase sales by about 10% every year until 2019. The shine on that first-year model was such that it was recently voted one of the best used-car buys under $10,000. Still in its first generation, the Encore soldiers into the 2022 model year with a few small changes. The biggest update for the 2022 Encore is a newer 1.4-liter four-cylinder engine with more power. The previous unit produced 138 horsepower and 148 pound-feet of torque; the new 1.4 will unleash 155 hp and 177 lb-ft. That engine will only be available on the Preferred trim — which is the only one left. In 2018, the Encore came in six flavors. Whittling reduced that to a base model and a Preferred model for 2021, and for next year the base departs. Also (kind of) under the hood, an electric heater and defroster replace the traditional heater core system, for faster toasties in cold climes.  The only change outside is the addition of an exterior temperature sensor. Inside, the eight-inch infotainment touchscreen shrinks to become a seven-inch touchscreen. The passenger's seatback will no longer fold flat, so Buick took the opportunity to add a seatback map pocket to the shotgun position. Buick will charge $25,795 for the 2022 Encore, that figure including the $1,195 destination charge. It's the same price as the 2021 Encore Preferred.  The continued paring of the lineup suggests GM is ready to wind the model down now that the tiny-bit-larger and more profitable Encore GX is killing the Encore in the sales race. Through the end of September, the Encore is down on its 2020 sales volume in the U.S. by about half, whereas the Encore GX has more than doubled its 2020 sales so far this year. Automotive News reported that the Encore will quit the U.S. market in 2023 without a replacement as the automaker digs into its electric efforts. GM Authority believes there's a chance the new-generation Encore sold in China could come here.
