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.

Is this GM's next electric crossover?

GM made headlines this week when CEO Mary Barra presented the company's electrification and automation plans at the Barclays Global Automotive Conference in New York. "We are committed to a future electric vehicle portfolio that will be profitable," Barra said, which could be taken as a jab at Tesla. In the presentation ( PDF here), though, we see a new vehicle in a slide titled "Leveraging existing BEV platform to expand in near term." The vehicle, seen above, accompanied the captions "New CUV entries" and "two entries by 2020." Is this a sneak preview of an upcoming electric crossover from GM? The image seems too realistic and intentional to be a random placeholder. If this is, indeed, an upcoming battery-electric CUV based on the Bolt, the question remains: Will it be a Chevy or a Buick? It has no visible badging, but it shares DNA from both brands. As Inside EVs points out, though, it does bear a resemblance to the Chevrolet FNR-X concept unveiled in Shanghai earlier this year. With two CUVs on the way, it's not unthinkable that there could be a version for each brand. In addition to this slide, the presentation includes plans for an "All new multi-brand, multi-segment platform" launching in 2021. The all-new modular battery system will cost less than $100 per kWh, providing higher energy density and faster charging. The platform will host at least nine different vehicles, including a compact crossover, seven-seat luxury SUV and a large commercial van. GM has said it will launch 20 new EVs by 2023, and that it targets 1 million EV sales per year by 2026. Many of those sales will be in China. Related Video:

1987 Buick GNX with 8.5 miles sells for ... well, you won't believe it [UPDATE]

UPDATE, FRIDAY, FEB. 15: Blowing past what was believed to be the previous sales record of $165,000, this 8.5-mile 1987 Buick GNX sold for $200,000. It jumped approximately $80,000 in the final 10 minutes. The winning bid went to username PETRO917, who joined Bring a Trailer in February, seemingly specifically to bid on the GNX. The previous story appears below. Automotive grails are expected to cost unfathomable amounts of cash, but this 8.5-mile (EIGHT!) 1987 Buick GNX could reach monetary digits not seen before. With four days still left on the Bring a Trailer auction, the GNX is already up to $100,000. The Grand National, particularly the GNX, is one of those cars that has skyrocketed in value in the past 10 years. It's been earning payouts that put it in a rare class of General Motors vehicles typically occupied by classic Corvettes and Camaros. At the Barrett-Jackson Palm Beach auction in 2015, a 362-mile example sold for a brain-scrambling $165,000, likely the most ever paid for a GNX. Last year, the first GNX ever released to the public (VIN No. 1 and 2 were kept by the company) had 8,200 miles and sold for $126,500. The most expensive GNX ever sold on Bring a Trailer had 28,000 miles and ended at $60,000 in summer 2018. Bidding on this example is already $40K past that, with days to go. To the shock and dismay of many, this ultra-rare performance icon has been driven less than the distance of a half marathon. Its odometer reading makes it possibly the most pristine GNX on the planet. After it was originally sold in Mena, Arkansas, it simply sat on display in a Texas dealership for decades. The seller purchased the car in 2002 and supposedly kept it in a climate-controlled environment. Plastic wrapping over the seats and door panels further the immaculate cleanliness. According to the listing, the only parts that have been replaced are the battery and a relay switch, both of which come with the sale. In a comment on the auction, the owner shared the reason he has decided to sell the car: Collecting is enjoyable only if you can share the collection with other people of similar mind who can also appreciate it. I am at a point in my life when the relationships, not the material possessions, mean the most to me. The time has come for someone else to own a piece of history and share it with those individuals most important in his or her life.
