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 to build outgoing Silverado and Sierra until late 2019

As it has done with previous generations, General Motors is keeping the outgoing versions of its 1500 pickups in production despite the arrival of the all-new 2019 Chevrolet Silverado and 2019 GMC Sierra. The production of the previous, K2 generation models will begin to be wound down gradually, according to Automotive News, starting with crew cabs "early next year," and double and regular cab models following during "the early second half of next year." The old model trucks will continue to be built into "late 2019" based on market demand, GM's spokesperson Kim Carpenter said. The Chevrolet will go by the name Silverado LD, with the GMC Sierra designation still to be announced. Some of the outgoing models are built by sharing the assembly work between two GM plants. Partially finished Silverado and Sierra double cab bodies are shipped from Fort Wayne, Ind., to Oshawa, Ont., where the trucks are completed, including receiving paint. This eases the workload in Fort Wayne, where production of the new T1 generation trucks started in July 2018. In January, the Silao plant in Mexico will take on the duties of building new generation regular cab and crew cab trucks. Carpenter also said that the "Oshawa shuttle," as the shared production is called, has been very successful. As a result, 60,000 more trucks will be built than what the original production forecast initially called for. GM's latest quarterly profits, disclosed last week to be $1 billion, have been far higher than expected and will result in full-year profits far higher than what had been predicted in light of steel tariffs. GM isn't the only truck maker taking a similar multi-generation approach for 2019. Both the outgoing and redesigned Ram 1500 are in production, with the previous generation being dubbed Ram 1500 Classic. Related Video:

GM cutting Chevy Sonic, Buick Verano production [UPDATE]

UPDATE: A previous version of this story indicated that Orion Assembly would be idled for seven weeks, from February 16 through April 6. This was incorrect. The factory will instead only be idled for the weeks of February 16 and April 6. The story has been edited to reflect this. General Motors has announced that the factory responsible for the Buick Verano and Chevrolet Sonic will be idled for the weeks of February 16 and April 6, with blame being placed on excess supply. The Orion Assembly plant, about 45 minutes north of GM's Renaissance Center headquarters, employs about 1,800 people, but they'll be given a pair of furloughs as inventories of the sub-compact Sonic and premium compact Verano reach 127 days and 84 days, respectively. That works out to 26,600 Chevys and 9,800 Buicks waiting for buyers. According to Automotive News, the compact Chevy sales bested the industry average in 2014, jumping up nine percent versus the the overall segment's eight-percent gain, while the Buick sedan's sales were down four percent. When asked about the shutdown, a GM spokesman told AN that it will "build to market demand," while also pointing out that the company did not comment on production plans.
