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.

The new Opel Insignia might be a great Buick, but it's a sad Holden Commodore

Since the first shots of the uncovered Opel Insignia hit our inboxes, we've been filled with excitement for the new sedan. It looks great, it should come to America with little to no visual changes as the Buick Regal, and we might even get a wagon version. Unfortunately, there's a lead lining to this silver cloud, and it comes to us from Down Under. You see, the Opel Insignia is also undergoing a re-badging job in Australia to become the new Holden Commodore. It's replacing the beloved rear-drive Commodore (with an optional V8 and ultra-high performance HSV variants) with a front-drive-based platform offering four- or six-cylinder engines. This is depressing news considering the Zeta-platform underpinning the Commodore VF spawned the Pontiac G8, Chevrolet SS, and fifth-generation Camaro. Knowing this was going to happen doesn't help much either. What makes it all worse is that the new Commodore doesn't have a shred of unique styling in the bodywork. That's not an exaggeration. A new grille with a Holden lion badge instead of an Opel lightning bolt badge is the only change. See for yourself in the Insignia gallery below. Not only did GM erase a unique Australian model, it didn't even allow the brand to give the car a distinct shape. It's sort of like when Ford planned to replace the Mustang with the Mazda-derived Probe. The Probe wasn't that bad for the time, but it was no Mustang. At least in that case the Mustang survived. View 12 Photos Before we get ourselves too down, we should mention that there are reasons to be hopeful for the future. For one thing, the new all-wheel-drive Commodore/Insignias will come with a version of the GKN-developed rear differential found in the Focus RS and Range Rover Evoque, which is pretty neat on its own. And Opel/Vauxhall have always had wild performance versions of the Insignia and its Vectra predecessor. The last one made 325-horsepower and had all-wheel-drive. A new one would likely produce much more, since one of the available V6s makes 308 horsepower. Then imagine all of that extra hypothetical horsepower hooked up to the all-wheel-drive system that introduced us to "drift mode." Not only that, but rear-drive Holdens may not be completely dead yet. A Belgian man announced his intention to buy an old Holden factory along with the tooling and rights for the car once it was discontinued. His plan is to continue producing the old model after Holden is done with it.

2018 Buick Enclave: How engineers made it larger, lighter, more sophisticated

Buick used the unveiling of the 2018 Enclave at the New York Auto Show to introduce its new range-topping Avenir sub-brand to the world. With fancier interior finishes and exterior details, it's Buick's latest effort to make itself a proper luxury brand (or perhaps re-establish itself as such). However, lost in the Avenir song and dance is the fact that the 2018 Buick Enclave is a (very) long-awaited all-new model regardless of the trim level one selects. Like the Chevrolet Traverse upon which it is based, the new Enclave is bigger than the vehicle it replaces but considerably lighter, by about 400 pounds. "We told every engineer, 'get your job done, but then take the weight out,'" said engineer Rick Spina as we hovered next to his larger yet lighter creation. His team therefore set about taking a little bit of weight out from just about everywhere, from using additional aluminum in the suspension to varying the thickness of the frame (thicker in places that needed to be stronger, thinner and therefore lighter in places that didn't). Only about 100 pounds came out of the body with the rest coming from elsewhere. Not only will the reduced weight improve fuel economy (Buick-estimated at 19 mpg combined with FWD versus 18 for the 2017 model) and presumably the old Enclave's rather ponderous handling, but it should only make things easier for the new powertrain: General Motors' now-familiar 3.6-liter V6 and its latest nine-speed automatic. With 302 horsepower and 260 pound-feet of torque, Buick says the new engine will need 7.2 seconds to reach 60 mph with FWD or 7.5 seconds with AWD. That's a second quicker than before. Besides acceleration, towing is also bumped up by 500 pounds to 5,000. For those models with all-wheel drive, the Enclave has the same basic system featured on range-topping versions of the Buick LaCrosse. Besides power being sent front and rear, it can also differ from right to left in the back, although Spina is quick to point out that capability is for traction-enhancing purposes rather than sporty, handling-enhancing torque-vectoring ones. Buick owners already appreciated the Enclave for its quietness so the engineers decided to take it that much further. This included altering the exhaust, improving body sealing (there are triple door seals), including active sound deadening and utilizing advanced materials that absorb sound as opposed to simply being thick, dense and heavy enough to keep it out.
