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.

One of the world's largest muscle car museums is auctioning off its cars

Rick Treworgy's Muscle Car City is one of the biggest collections of high-performance American cars in the world. With over 200 cars of mostly GM makes, it's a mecca for fans of the golden age of Detroit iron. Unfortunately, the museum will be shutting its doors for good on Jan. 17 and auctioning off most of its assets with no reserve. The collection is, to put it bluntly, astounding. Advertised as a combined 65,000-plus horsepower, it occupies a 60,000-square-foot retail space in Punta Gorda, Fla., in a former Walmart store. It make sense when you learn that founder Rick Treworgy made his fortune in the commercial real estate business. As a hobby, he began to amass a truly jaw-dropping collection of muscle cars, filling out a collection that often has every year of a particular model represented, or a grouping of the rarest and highest-performance option packages of that year or model. Often, Treworgy bought placeholders while scouring the country for even rarer versions. It helps that Muscle Car City also houses a showroom where unwanted cars are sold, as well as its own speed shop that stocks plenty of parts. There's even a '50s-style diner called Stingray's Bar and Grill. According to a 2014 episode of Car Crazy, Treworgy has 80 Corvettes alone, more than the actual Corvette Museum. Among them are 20 models from 1967, one of Treworgy's favorites. The rest span the decades from 1954 (he once had a '53 but sold it) to a recently acquired 2020 C8, which, according to The Drive, has only 300 miles on the odometer. You like Impalas? There are models of every year from 1958 to 1969. El Caminos? He's got 'em from 1964 to 1972. Novas? Every year from 1963 to 1970 is represented. Most are the more desirable examples of each breed, with four-speed transmissions, the biggest blocks, and unicorn option packages like a factory 1965 Z16 SS396 Chevelle, one of 200 that were ordered off-menu at Chevy dealerships. And don't even get us started on the Camaros, which include not one, but two COPO 1969s. Treworgy even owns the only known surviving example of a 1936 Chevrolet Phaeton, of which only seven were built. On top of it all, many of these cars are concours quality and have won awards at prestigious car shows. While it's sad to see a collection like this broken up, Treworgy told The Drive that he'd been planning to retire next year anyway. However, the COVID-19 pandemic sped up those plans, greatly reducing the number of visitors to his museum.

2020 Buick Encore GX pricing makes it a better bargain than the smaller Encore

In April, Buick revealed the Encore GX at Auto Shanghai. At the time, we thought there was a chance the slightly larger GX would supplant the Encore in the U.S. By August, we learned that wouldn't happen, the Encore GX slotting into the lineup between the Encore and the Envision. With nearly $8,000 between the starting prices of the Encore and the Envision, there'd be plenty of room for the GX to find a good home leaving plenty of MSRP daylight between the crossover bookends. That doesn't appear to be what's happened, though. CarsDirect got hold of an early order guide for the Encore GX, and writes that the Encore GX in Preferred trim will cost $24,100 before a $995 destination charge, totaling $25,095. That's $900 more than the entry-level Encore in 1SV trim, but $500 less than the Encore in comparable Preferred trim.    The Encore offers an intermediate Sport Touring trim between Preferred and top-level Essence trims. The Encore GX will come in an intermediate Select trim, which CarsDirect didn't mention a price for. Stepping up to the top Essence variant with front-wheel drive costs $29,495 for the Encore GX, $800 less than a similar Encore, which costs $30,295.   If these are the figures that show up on dealer lots, the Encore GX seems like a no-brainer. The Encore rides on an older GM platform called GEM, for Global Emerging Markets, the GX model is built on GM's new VSS-F architecture. Both are fine looking vehicles, but the GX is a little more handsome. The Encore offers one engine, a 1.4-liter four-cylinder with 138 horsepower and 148 pound-feet of torque, shifting through a six-speed transmission. The base engine on the Encore GX will be a 1.2-liter turbocharged three-cylinder with an estimated 137 hp and 166 lb-ft, shifting through a CVT. The second GX engine is a 1.3-liter turbocharged three-cylinder with an estimated 155 hp and 174 lb-ft, optional on the front-wheel drive Select and Essence trims, standard on every all-wheel-drive model. That more powerful motor shifts through a nine-speed automatic.  As if all that weren't enough, the GX's reason for being is that it offers more room. An additional three inches in length provides an extra 4.7 cubic feet of cargo room behind the second row. The GX wins on safety, too, coming standard with tech like forward collision alert, lane keep assist, lane departure warning, and automatic emergency braking.
