GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

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.

GM re-recalls 11k SUVs

General Motors is recalling a bunch of previously recalled SUVs because, well, they still aren't quite fixed. The latest repairs are necessary on 10,974 SUVs in North America, including 9,932 in only the US. Affected models include the 2006-2007 Buick Rainier, Chevrolet Trailblazer, and GMC Envoy; plus the 2006 Trailblazer EXT and Envoy XL. While not listed by NHTSA, a statement by GM to Autoblog says the 2006-2007 Saab 9-7X and Isuzu Ascender are also affected. In these SUVs, it's possible that liquid could get into the driver's door master power window switch module and cause a short circuit. This could potentially lead to a fire, and owners are urged to park the vehicles outside until repaired. GM has been trying to fix this issue for years. It started as an investigation into fires, and that led to a recall for about 250,000 vehicles in cold-weather states. A nationwide campaign came in 2013 for 193,000 of them in the US. Last year, the automaker decided to replace the whole module as a repair. However in a recent investigation of these recalls, GM discovered that this latest group of SUVs never received the new part. According to documents submitted to NHTSA (as a PDF), "Some dealers incorrectly used the labor code associated with module replacement when, instead of replacing the module, they only added a protective coating to the module." To fix things this time, the models finally get the correct component.

Certain 2006 Chevrolet TrailBlazer EXT and GMC Envoy XL, and 2006-2007 TrailBlazer, Envoy, Buick Rainier, Saab 9-7X and Isuzu Ascender vehicles may continue to have a condition in which the printed circuit board inside the driver's door may corrode and short if exposed to certain fluids such as melted snow containing road salt. GM is aware of four fires but no crashes, injuries or fatalities associated with the expanded recall. The total number of vehicles being recalled, including Canada, Mexico and exports is 10.974. Customers are urged to park these vehicles outside until repairs have been made. GM reported this recall to the NHTSA on September 23.
