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 Avenir concept struts into Motown

We love auto show surprises, and Buick has already gifted us a sparkly package on the eve of the 2015 Detroit Auto Show. Dubbed Avenir, this four-door concept is said to signal the future of the Trishield brand by previewing a possible flagship sedan. Incorporating time-honored Buick design hallmarks like the sweep-spear profile, Ventiports, and even a subtle boattail rear-end, the four-place sedan is powered by a surprisingly real-world powertrain – namely a next-generation V6 with cylinder deactivation and stop/start, with the most interesting part of the driveline arguably being a "twin-clutch all-wheel-drive system" and a nine-speed automatic gearbox with paddle shifters. Make no mistake, this is a big car. At 204.5 inches long, it's longer than a standard-wheelbase Cadillac Escalade – a span that's emphasized by the car's long hood and waterfall grille – though it's not quite as wide. While clearly a showcar, the beautifully crafted interior looks largely produceable, including attributes like a next-generation 12-inch touchscreen infotainment system and 4G LTE wifi, but we suspect a production car would pick up a third rear seatbelt and give away some of its flowing contours that are said to have been "inspired by nature and sea waves receding on a beach." No word yet on whether there's actually a showroom future for a car like this – it could simply be an exercise designed to test the waters for a next-generation LaCrosse. After all, sedans aren't exactly popular concept fodder these days, especially as crossovers continue to eat into traditional sedan sales in many of the world's markets. However, China still loves the coddling rear seats of a proper four-door sedan (which in this case include silk and bamboo elements), and with a majority of Buick sales happening in the People's Republic, the Asian nation controls the destiny of this General Motors brand. Said another way? Anything is possible, especially with General Motors known to be working on a large flagship sedan for Cadillac already – the Avenir is reportedly based on the same Omega architecture that will underpin the forthcoming CT6. What do you think? Is this a promising direction for the resurgent Buick? Scroll through our gallery, check out the video, and then have your say in Comments.

PSA's purchase of Opel from GM is expected to be finalized soon

PSA's purchase of the Opel/Vauxhall division from General Motors is expected to be officially announced on Monday, according to The New York Times. PSA, the parent company of European automakers Peugeot and Citroen, will reportedly hold a joint press conference with GM in Paris to announce the deal. GM has worked as part of an alliance with PSA in Europe since 2012. The deal could be a big boon for both companies. For PSA, the addition of Opel and Vauxhall into its fold would catapult the automaker into second place behind Volkswagen for European marketshare, and would allow the company to spend research and development costs across a greater number of vehicles. And GM, which has struggled in recent years to turn a profit with its European division, would be able to focus more squarely on the areas where it's most profitable and to invest in future technologies like automation. But the deal isn't without its potential pitfalls, primarily for PSA. GM hasn't been able to make a success of Opel and Vauxhall, and it's not a sure bet that PSA will, either. What's more, the addition of Opel and Vauxhall doesn't expand PSA's reach any further into new markets, like China or India. The NYT cites data from Ferdinand Dudenhoffer, a professor at the University of Duisburg-Essen in Germany, showing that 70 percent of PSA and Opel business is done in Europe, a market that has been shrinking since 1999. We'll have to wait a few days to see exactly how the deal between PSA and GM will be structured. We're also curious to see how the loss of Opel may affect GM's lineup in the States, especially for Buick, since the company's Regal sedan is based on the European Opel Insignia. In other words, stay tuned. Related Video:
