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.

2016 Buick Cascada First Drive

Florida became a state in 1845. It is the third most populous state in the United States, home to the most-visited theme park in the world. It is where you'll find every convertible ever sold in the United States, be it a pasty white Infiniti M30 or a Lamborghini. And soon, many examples of the 2016 Buick Cascada will call it home. Florida is full of Buicks. Wonder if anyone bought a Rendezvous Ultra? It's in Florida. The Buick Reatta, the company's last convertible before this? Also there. Buick, however, is eager to get those who better remember Bush vs. Gore than Nixon vs. Kennedy to ask, "That's a Buick?" Which is how we arrive at the Cascada. The Cascada isn't so much a new Buick as a car that's new to Buick. It's been on sale for about three years as the Opel Cascada in Europe, along with badge-engineered siblings sold by Vauxhall and Holden in other parts of the world. Buick took that time to make several hundred changes to the Cascada for US consumption and then found it without many rivals. The Chrysler 200 convertible, Volkswagen Eos, and Volvo C70 would all be prime targets for the Cascada here, were they not all dead now. Buick's gamble is that these Chrysler, VW, and Volvo (also Saab, for that matter) customers are looking for somewhere to go next. The Cascada isn't so much a new Buick as a car that's new to Buick. One thing is certain: the Cascada is eye-catching to Floridians. I had no fewer than six people in Miami and Key West walk up to me and ask what kind of car it was, or even say, "That's that new Buick convertible, right?" Despite being three years old, the Cascada's looks have aged pretty well. And it's been spared many of the tacked-on details, like fake portholes and chrome wheels, that were adhered to the Regal when it made its trip over from Opel-land. Top up or down, the Cascada is attractive. Unlike the Audi A3 or BMW 2 Series convertibles (the former being the Buick's prime target), there's no abruptness to the design, no sharply ending lines. The Buick looks relaxed in a Palm Beach or Palm Springs way, even on the inside with the convincingly stitched dash top and standard heated leather seats (one of the pieces redesigned for the Buick). That being said, the pattern on the seat material is a misstep, looking like it was inspired by Aunt Flora's 1972 patio furniture. Then it's surprising that you don't exactly sink into the Cascada. While the seats are mounted low, they're not pillow soft.

Trademarks indicate Buick Regal wagon could be on the way

American wagon fans have been waiting for General Motors to import a Buick-badged version of the Opel Insignia Sports Tourer since the current Insignia-based Regal hit dealers. If a new patent filing is any indication, that day could be coming soon. Then again, it might not mean anything. AutoGuide reports that Buick has filed two trademarks with the US Patent and Trademark Office for "Motor land vehicles, namely automobiles." You can see the trademarks for "Tourx" and "Regal Tourx" here and here. "Tour" smacks of wagon models, while the "x" – for all-wheel drive – makes us wonder if maybe we'll be seeing a rebadged version of the high-riding Opel Insignia Country Tourer (shown above). This isn't the first time Buick has stoked the hopes of US wagon fans, though. Earlier this year, trademarks were filed for the "Regal Sport Touring," a name that's very close to the Euro-market wagon's title. In fact, that trademark had the same description as the Tourx/Regal Tourx filings. As we've established before, automakers file trademarks all the time. It's far from a guarantee that anything will come of such trademarked names. Still, two wagon-ish filings with the USPTO from Buick in under a year makes it seem like there's at least someone at the Trishield brand that's campaigning for a long-roof Regal. Fight the good fight, friend. Related Video:
