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 adds Sport Touring trim to sedan lineup

Buick has made a few tweaks to its sedan lineup today, announcing that a new Sport Touring trim will be offered on the LaCrosse, Regal, and Verano. It's best to think of the new Sport Touring models as Buick's answer to Chevrolet's limited range of RS models, focusing on very small style changes rather than any added performance. Best to leave that to the Regal GS, we guess. For the ST trim, Buick has fitted its three four-doors with new 18-inch wheels. These relatively sporty hoops get machined faces with black inserts, like those offered on the Encore Sport Touring and the Enclave Tuscan Edition. Also coming to the LaCrosse, Regal, and Verano Sport Touring is a new rear spoiler. Like we said, these are simple styling packs meant to spice up the staid but handsome exteriors of the brand's sedans. "These new ST models underscore the importance of design choices, while complementing the safety, refinement and connectivity technologies that are drawing new customers to Buick dealerships," Buick VP Duncan Aldred said in the attached statement. The new trim level will be available on all three vehicles this fall, with prices to be announced closer to the on-sale date. Scroll on for the official presser from Buick.

Buick Riviera Concept debuts in China

It's nighttime in China, and Buick has just concluded an evening event the day before the first - and only - press day of the Shanghai Motor Show. The star of this evening's party was the Buick Riviera concept vehicle, a plug-in electric hybrid coupe that the automaker says gives a glimpse at its future design direction, not to mention resurrecting some nomenclature from the brand's history that includes a similarly named concept from 2007.
The shape of the Riviera is said to be inspired by water. While the traditional Buick "waterfall" grille is present, the front end gains a more aggressive note thanks to what appear to be vertical air inlets below each headlight.
As for the concept's drivetrain, Buick says it uses General Motors' new dual-mode wireless plug-in hybrid electric vehicle propulsion system, or W-PHEV for short. The keyword there is 'wireless,' as the Riviera can charge its onboard battery packs with a traditional cable or wirelessly via a "sensory recharge panel" underneath the car.
