2017 GMC Acadia adds four-cylinder and All Terrain model

General Motors has officially started the process of updating its long-in-the-tooth fullsize CUVs by unveiling the second-generation GMC Acadia at the 2016 Detroit Auto Show. While the Acadia is 700 pounds lighter, it's also shorter and narrower, which means it's not quite the people mover it used to be. You'll no longer be able to haul eight passengers, although there will still be five-, six-, and seven-passenger offerings. While families might not be thrilled with the loss of a seat, the lighter weight is a net win. Not only will the V6 model feel more powerful and efficient – in addition to the lower curb weight, there's a new, 310-horsepower engine – but it will also likely be more economical. GM estimates the front-drive V6 will return 25 miles per gallon on the freeway, compared to 24 mpg for the current front driver, but city fuel economy remains pegged at 17 mpg. In a move we're not entirely sold on, though, the Acadia will also adopt a four-cylinder engine, and no, it's not GM's highly regarded 2.0-liter turbo. Instead, you'll be able to order this 4,000-pound CUV with a 2.5-liter, 194-horsepower four-cylinder. What it won't be able to provide in straight-line speed, it will make up for with fuel economy. GM is wagering the front-drive, four-cylinder Acadia will net 22 mpg in the city and 28 on the highway. Both engines are paired with a HydraMatic 6T75 six-speed automatic. A new All Terrain model is said to be optimized for wet, snowy and icy conditions, and its drive mode selector removes the Off Road selection in favor of All Terrain. We have live images of both the new Acadia Denali, as well as the new-for-2017 All Terrain model, direct from the floor of the 2016 Detroit Auto Show.

2020 GMC Acadia AT4 priced just a little more than the SLT trim

Cars Direct has seen the order guide pricing the 2020 Acadia AT4 at $42,495 after destination; that means a $41,300 MSRP plus $1,195 for shipping and handling. GMC has left a lot of pricing room between the rugged, all-wheel drive AT4 and the dressed-up, top-shelf Acadia Denali with AWD, the latter costing $49,495, a $7,000 difference. The spread's blown out some by what appears to be an $800 increase for the 2020 Acadia Denali with all-wheel drive. The 2019 model costs $48,695. On the other hand, it looks like the 200 Acadia SLT trim has gone down in price. Cars Direct says that model will run $41,995, which is $300 less than the 2019 version that goes for $42,295 after destination. The new price leaves a $500 gap between the SLT-1 model with all-wheel drive and the AT4 trim, a figure that's a no-brainer to justify for any buyers trying to get a more butch curb appeal.     The Acadia AT4 package comes standard with all-wheel drive and the 3.6-liter V6 with 310 horsepower and 271 pound-feet of torque, puts black chrome on the grille, and nabs a set of exclusive 17-inch wheels on all-terrain tires. The other two engines in the lineup are a new turbocharged 2.0-liter four-cylinder with 230 horsepower and 258 pound-feet of torque, and cylinder deactivation. That motor will be the standard kit on the SLT and Denali trim levels, supplanting the 3.6-liter that's standard on the 2019 models. The entry-level engine carries over, a naturally aspirated 2.5-liter four-cylinder making 193 horsepower and 188 pound-feet of torque.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.
