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 shows US dealers 2016 Cascada convertible

The affordable four-seat convertible has become a largely forgotten genre in the States, especially with the death of the Chrysler 200 Convertible. Of course, there are still premium options from Audi, BMW and Mercedes-Benz - not to mention more overtly performance-oriented droptop pony cars from Chevrolet and Ford - but if you want an affordable cruiser, you're kind of out of luck. That may be about to change, however, with renewed rumors of the Opel Cascada (pictured above) making it across the Atlantic wearing a Buick badge.
According to GM Inside News, Buick showed off the Cascada to US dealers last week, with renewed word that the company plans to bring it over from Europe for the 2016 model year. The US version will reportedly be practically identical to its German cousin in terms of styling, but the powertrain underneath is less certain. According to GMI, it may use the 1.6-liter turbocharged four-cylinder that is available in Europe with either 168 horsepower or 197 hp.
The Cascada rides on GM's Delta II platform, which also underpins the Verano, and the latest rumor certainly provides even more evidence that the convertible is probably on the way. Speculation about the droptop started when GM CEO Dan Akerson said last year that the car was on his wish list to bring over. Then, the US trademark on the name was reserved earlier this year, and the release was speculated for sometime in early 2016.

Buick Adam a reality after all... but only in China

General Motors may have parred down its brand portfolio, but it still has more under its umbrella than most. That's why, while a company like Ford might market the same vehicle under its own name in markets around the world, GM uses different brands in different markets. But no two are aligned quite as closely as Opel in Europe and Buick in the United States and China.
What we know here as the Buick Regal is sold overseas as the Opel Insignia. Our Encore is their Mokka. Verano? Astra sedan. But one thing we don't get here is the Opel Adam. The diminutive city car is GM's take on the Mini Cooper, Fiat 500, Citroën DS3 et al. Launched at the 2012 Paris Motor Show, the Opel Adam is named after the company's founder (like an ironic thumbing of the nose to the Ferrari Enzo). But while it's sold, like most Opels, in the UK as a Vauxhall, the prospect of it porting over to Buick seems slim to none. Right?
Sorta. While the Adam isn't likely to come Stateside, the latest reports (as yet unconfirmed by GM) suggest that The General is planning to sell the Adam in China where the Buick brand is also a strong seller. Local production could ensue, with prices targeting the Fiat 500 and engines - according to CarNewsChina.com - to include inline-fours displacing 1.2 and 1.4 liters with 69 and 100 horsepower, respectively.
