GM issues stop-sale for 3 SUVs over incorrect MPG rating

This week, GM sent a memo to Chevy, GMC, and Buick dealers to tell them to stop selling three SUVS. The 2016 Chevy Traverse, the GMC Acadia, and the Buick Enclave all have EPA window stickers that show higher fuel economy ratings than the vehicles actually have. Unlike other recent – and very public – fuel economy ratings problems from VW and Mitsubishi, it doesn't seem like GM did anything wrong with the testing for these vehicles, it just misprinted the labels. New labels are being printed and should arrive at dealerships this weekend and early next week. After that, the SUVs will be able to be sold and delivered again. The official fuel economy rating for the three SUVs are all the same. The correct numbers for the all-wheel drive versions are 17 miles per gallon combined, 15 city, and 22 highway. The stickers say the SUVs get 17/24/19. The front-wheel driver models were also incorrectly labeled, and the total number of affected vehicles is 59,823. In the memo, GM said the problem was caused by an "inadvertent error," Automotive News says. GM is working with the EPA to solve the issue. We have asked GM for a comment on the mistake and will update this post if we hear back. Related Gallery 2013 GMC Acadia View 16 Photos News Source: Automotive News – sub. req.

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 Blackhawk concept headed to auction block again

While the collector car auction market is often criticized for inflating the price of vintage models out of the realm of affordability for many buyers, these sales do give us an opportunity to look back on some of the beautiful, rare designs of the past. Just take a glance at this Buick Blackhawk concept with a shape right out of the '40s or '50s. Despite the heritage styling, it was pieced together from older pieces for Buick to celebrate itself in the early 2000s With styling inspiration from the classic Buick Y-Job concept car, the Blackhawk mixes actual vintage components to create its curvaceous shape. However, the power retractable top is thoroughly modern being made from carbon fiber and stows in the deck lid when the roof needs to go down. After so much work on the outside, the Buick has something equally surprising under the hood. It's a 1970 455-cubic-inch (7.5-liter) V8 GS Stage III V8 with a claimed 463 horsepower and 510 pound-feet of torque, and for easy cruising the mill is linked to a four-speed automatic. Built in-house by Buick, the Blackhawk was once part of the General Motors Heritage Fleet, but the automaker sold it off in 2009 at the Barrett-Jackson auction in Scottsdale, AZ, along with many other members of the collection. The concept went for $522,500 after the buyer's premium, according to the auctioneers. Now, it's crossing the block again with no reserve as part of RM Auctions sale of the Andrews Collection on May 2, 2015, in Fort Worth, TX. The 75-car auction also includes highlights like one of seven 1962 Ferrari 400 Superamerica SWB Cabriolet models bodied by Pininfarina.
