Buick struggling to keep up with Encore demand

Buick is having a hard time keeping up with demand for its all-new Encore mini-CUV, according to a report from Automotive News. The stylish, lifted five-door went on sale in January, but dealers have reported that supplies have dwindled after the initial high demand, taking the proverbial "wind out of the sails."
General Motors admits that it underestimated demand for the diminutive Buick, which is built in Korea and sold as the Opel Mokka in Europe, where it's also seen success. Buick spokesperson Nick Richards told AN, "We increased production, so there have been a lot more landing within the last month."
Buick has done a booming business, though, even with its limited supply of Encores. With over 12,000 units sold in the first half of 2013, the small CUV is on pace to annihilate industry analysts' estimates, which predicted no more than 18,500 units in 2013. We're not entirely surprised. When we first drove the Encore late last year, Autoblog professed that we had no idea how sales would turn out, as the Encore wasn't really entering into an established segment. Even so, wefound a surprising amount to like in the Encore, enough that we "wouldn't bet against it" being a major success.

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 claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.
