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 trademarks 'Sport Touring' for Buick Regal, LaCrosse

Discovering trademarking or patents from automakers always fascinates us since the filings hint at the possible future of motoring. Based on two recent applications, Buick has something possibly brewing for two of its sedans, because the company now has the trademark for Sport Touring on the Regal (pictured above in GS trim) and LaCrosse. According to GM Inside News, both trademarks are dated April 27 and are simply described to the US Patent and Trademark Office as being for "motor land vehicles, namely, automobiles." That doesn't narrow things down at all. However, since the moniker is specifically for both sedans, Sport Touring might be a new trim or special edition for them. Buick had no comment when reached by Autoblog. Of course, there are a whole host of automotive trademarks that are claimed that end up with no actual vehicle in showrooms. Unfortunately, we just have to wait to find out if this is another case like the Buick Enclave Tuscan where the filing offers a preview of the future or a situation like the still long-awaited return of the Supra.

The new Buick Regal looks like a Mazda, and we're totally cool with that

Yes, this undisguised Opel Insignia, which will be brought here as the next Buick Regal, looks a lot like a Mazda. You can see it in the grille and headlights, especially – in fact, if you look at one of the photos with tape blocking out the badge in the middle of the winged grille, you might think this is a new Mazda6. The thing is, Mazdas look pretty darn good, so no one's complaining. And when you look at the rest of the car, there's a fair amount of originality going on. Aside from the GM-generic taillights (they look like they could fit on a Chevy, right?) the lines and details are all pretty fresh, and there are some design elements pulled from Buick's gorgeous Avista concept. A sweeping roofline leads to some healthy shoulders at the back, creating a coupe-ish profile with a very abbreviated rear deck. This appears to be a hatchback model and not the four-door sedan, but the general look should carry over. This is definitely a big improvement over the somewhat bulbous current-generation Regal, which also started life out as an Insignia. The car shown here is the Insignia OPC model, with Brembo brakes, big wheels, side skirts, and a front end with big (likely fake) intakes. It will most likely translate to a Regal GS for our market, as is the case with the current OPC and GS. The new Regal/Insignia is expected to use the same platform as the new Buick LaCrosse, which is also shared by the Chevy Malibu and Impala. They should once again be available with front- or all-wheel drive and a choice of turbocharged four-cylinder engines. Rumor has the Opel versions debuting at the Geneva show March, and the Buick would likely follow, possibly in New York in April. View 13 Photos And then there's the wagon. All signs point to Buick finally bringing the most practical Insignia to our market as a Regal. We got wind of a focus group testing the idea, Buick has trademarked the name Regal Tour X. That version would likely go up against the Audi Allroad in the classy, slightly lifted all-wheel-drive wagon category, basically acting as an almost-crossover for people who want a wagon but won't admit it to themselves. The Insignia wagon caught here is also an OPC, and we think it looks even more handsome than the hatch-sedan shown above. The trim piece stretching from the base of the A-pillar all the way up and back down to the tail is a nice touch in profile view, although we're not so sure about how it terminates abruptly at the taillight.
