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.

Next-generation Buick Enclave spotted with Wildcat looks

The rollout of GM's next-generation three-row large SUVs is well under way with the reveals of the 2024 Chevy Traverse and GMC Acadia. Another vehicle on the platform is also getting a redesign soon, according to these spy photos: the Buick Enclave. It's still going to be big, and it will now receive the same sort of Wildcat concept-inspired styling as smaller Buicks such as the Envista and Encore GX. The Enclave's front is where the Wildcat connection is the most clear. It has the pointy shark nose and wide, frowning grille. It's hard to say whether it will get a mesh grille like some of the production SUVs, or a slatted grille like the concept. High up are slender daytime running lights with the actual illuminating headlights hidden lower in the outboard air intakes. We're not totally sure if this look will work on such a large, tall vehicle, but we'll reserve final judgment when we can see the car with all its paint and trim on display. The sides of the Enclave still have a fair bit of the Coke bottle curves that have appeared on every Enclave, if a bit more toned down. The greenhouse seems to take after the GMC Acadia more than the Traverse, as it seems it has a relatively thin C-pillar. The D-pillar looks quite thick, which will probably be toned down with judicious application of gloss black plastic.  Details of the rear are difficult to make out. It seems to have slim, wide and curvy rear taillights. The rectangular exhaust tips are nicely fitted to the rear bumper. But that's about all that stands out. We're expecting the Enclave to have basically the same powertrain as the GMC Acadia, with the one engine offering being a turbocharged 2.5-liter four-cylinder with 328 horsepower and 326 pound-feet of torque. It should be paired with an eight-speed automatic and either front- or all-wheel drive. Odds are it will not get an off-road variant like the Acadia AT4 or Traverse Z71. But it might get a sportier road-going version that could take advantage of the torque-vectoring dual-clutch rear differential from those aforementioned off-roaders. It should also be revealed sometime next year with deliveries likely in the same year. Related video:

Next-gen LaCrosse, Cascada convertible coming to Buick showrooms in 2016

It's difficult to overstate how significant the post-bankruptcy years have been for General Motors' Buick brand. Arguably the most improved American automaker, Buick has rounded out its range with an excellent compact in the Verano, a well-balanced midsizer in the Regal and a segment-busting mini-CUV, with the Encore. Seeking to keep that momentum going, the next several years will see the brand address a trio of its most obvious issues. First and foremost will be a replacement for the aging LaCrosse, a vehicle whose only bit of attention since its 2009 debut was a very light refresh in 2013. According to Automotive News, we should expect the next-generation LaCrosse to arrive late next year or early in 2016, as a 2016 model. AN expects big design changes, as Buick attempts to further the LaCrosse from its popular platform-mate, the Chevrolet Impala. The changes won't be so radical, though, as to do away with its front-drive architecture, as the latest version of the Epsilon platform will underpin the next LaCrosse. The 3.6-liter V6 is likely to carry on, although a smaller, budget-minded offering is also extremely likely (we'll eat our hat if it's not the 2.0-liter, turbocharged four-cylinder from the Regal, Verano and Cadillac CTS et al.). The other issue plaguing Buick's lineup is a lack of a midsize crossover. This is particularly damning for the brand as most of its showrooms are shared with GMC, which boasts its own midsizer in the form of the Terrain. With the upcoming Envision (see here for teasers), that problem should be addressed. Like the LaCrosse, the Envision will likely be a 2016 model. It will debut and launch in China early next year, while we can expect it to arrive stateside later next year, or even early in 2016. For American consumers, both a 2.5-liter four-cylinder and the aforementioned 2.0T could see action in the Envision. Finally, while Buick can boast a pair of vehicles available with manual transmissions, it's still far from what we'd call a brand for fun driving experiences. Of course, one way of solving that problem is with a two-door convertible. Yes, it's extremely likely that the Euro-market Opel Cascada convertible will be sold in the US early in 2016. Whether it keeps the Cascada name is unclear (all in favor of Skylark, say "aye"). Regardless, adding a reasonably priced, relaxed, two-door droptop to the Buick range to fill the space left by the not-so-dearly departed Chrysler 200 Convertible seems like a no brainer.
