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 Electra-X concept teased for Chinese audience

Buick is about to show its largest market, China, how the brand does an electric vehicle specifically for that clientele. The Tri-Shield released two images of the shark nose that will grace its Electra-X concept, a follow up to the Electra concept that debuted at the Auto Beijing in 2020. Instead of the 583-horsepower, high-riding, thick-bodied fanciful sedan of yore, the Electra-X should be a much more production-ready version of what Chinese buyers can expect. Buick China said that "The Electra-X concept takes Buick's innovative thinking and imagination of future electric mobility to the next level. It is designed to provide a safer, smarter and more desirable EV experience, building on Buick's deep understanding and insights of local consumers toward electrification and intelligent driving." This will be a different vehicle than the "groovy" EV concept Buick showed its American audience in February of this year, although there are similarities. Buick China also said of the Electra-X that it is "defined by the brand's all-new design language" that embodies "distinct and forward-looking styling, along with an airy interior." Another design trait will be slim, sloping DRLs, seen on the Chinese and U.S. concept teasers, with slight differences. The Asian market can also expect minimal surfacing, an ornate grille treatment, side mirror cameras, and trim A-pillars. Tech-wise, Buick says the Ultium-based product will come with Super Cruise and its Virtual Cockpit System. The China debut happens next month at 2022 Buick Brand Day. Our groovy EV debuts this summer, the automaker planning to have two electric vehicles in U.S. showrooms by the end of 2023. The Electra-X could give big clues about what's headed our way.

2020 Buick Encore, Encore GX set for Shanghai debut

Buick says it will debut the all-new 2020 Encore small crossover and new-for-China Encore GX compact crossover at the Buick Brand Night April 15 in Shanghai on the eve of Auto Shanghai 2019. They'll join the updated 2020 LaCrosse and LaCrosse Avenir sedans, which GM is discontinuing here in the U.S. Buick released a darkened teaser image of both vehicles in rear three-quarters view, though it's a little hard to tell which is which (we're going with the GX being the one on the right). It suggests the Encore gets more streamlined taillights that taper along the rear liftback, with some redesigned creases on the door panels and haunches. The latter don't appear to be present on the Encore GX, which Buick says is a new addition to the model series in China. Both will be offered with GM's new nine-speed Hydra-Matic and continuously variable transmissions, plus what Buick says will be "enhanced connectivity," including new technologies. They'll join the Envision and Enclave for China, which is Buick's largest market. First introduced in 2013, The Encore was last refreshed for 2017. It has been the top-selling Buick model in the U.S. for the past 3 years, with 93,073 sold last year, up 5.7% from 2017.
