NC dealer falsely announces return of Regal Grand National, Regal GNX

Like many new car dealers, Liberty Buick GMC gets so excited about its brands' new wares that it puts out press releases announcing when new models are on the way. That's not typically national news, but the Charlotte, NC store has created a bit of internet hubbub by announcing that it will be "one of the first dealers in the country to offer the Buick Regal GNX," and it's even started to add customers names to a waitlist. Only one problem: Despite seemingly annual rumors and calls for such a model, Buick hasn't announced any Grand National models at all – let alone a GNX – and no such models are actually in the cards. The Liberty Buick press release talks in a nostalgic, venerative tone of the original 1982-1987 GN franchise, and goes on to say: "These returning relics will be based on the highly-acclaimed Alpha vehicle architecture currently used in the Cadillac ATS, 2014 Cadillac CTS, and soon to be in the sixth-generation Chevy Camaro. Alpha is the internal name of a General Motors vehicle architecture engineered to underpin compact and mid-size rear-wheel-drive vehicles." In the release, Liberty Buick claimed the GN/GNX models would arrive in late 2015, citing a coupe bodystyle, including a rather fantastical-looking GNX rendering from Bestride.com. Unsurprisingly, none of this is true. Autoblog reached out to Buick for comment about the release, and brand communications manager Nick Richards confirmed that the company had discussed the matter with Liberty Buick representatives. Richards went on to say that the release was wholly incorrect, proclaiming "an agency [for the dealer] picked up a lot of stuff off the internet" and ran with it, including an old Car and Driver story from 2013. The dealership subsequently issued a retraction, with Scott McCorkle, owner of Liberty Buick GMC saying: "We love the idea of the Buick Regal GNX coming back to our showroom but for now, it's only a concept. Bottom-line, the article was incorrect.

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.

Question of the Day: Coolest factory-supercharged car?

Last week, we discussed possible engine-swap recipients for the plentiful-in-every-junkyard Eaton-supercharged GM 3800 V6 engine. The Buicks, Oldsmobiles, and Pontiacs that came with that engine from the factory were reasonably cool, of course, but when you look at all the production cars that have been available with supercharging over the decades you can find some pretty amazing stuff. My personal favorite has to be the Paxton-blown Studebaker Larks of the early 1960s, partly because the Lark was just about the stodgiest-looking, sleepiest little sedan available in America, possibly the most ridiculous recipient of a howling force-fed V8 imaginable, and partly because of the name of the optional supercharged 289-cubic-inch V8 you could get in the Lark: Jet-Thrust! What do you say is the coolest factory-supercharged car of all time? Related Video: Auto News Buick Automotive History Performance Classics supercharger questions
