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.

2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

Average transaction prices climb to a record $36,270 in January

The automotive sector made a hash of the numbers last month, a mess of pluses and minuses clogging the transaction-price charts according to Kelley Blue Book. The overall industry rose one percent, even though buyers bought fewer cars and light vehicles in January 2018 vs 2017 using the selling-day adjusted rate. Due to January transaction prices rising to $36,270, a record for January, the value of new vehicles sold climbed more than $1 billion compared to January 2017. KBB's transaction prices don't include customer incentives, which changes the complexion slightly; average incentive spending rose to just over ten percent. The average transaction price in December 2017 was $36,756, so January dropped a bit - nothing unexpected, with the month annually blamed for "January doldrums." More revealing is the fact that the average transaction price in January 2017 was $34,910. This year's plumped-up figure came courtesy of the continued shift to crossovers, SUVs, and light trucks, which shouldn't surprise anyone who's read an automotive blog in the past 20 years. That category comprised nearly 70 percent of new vehicle sales for the month. Some manufacturers profited more than others, though. Fiat Chrysler managed 12.8 percent fewer sales in January compared year-on-year, but the company's vehicles sold for $1,300 more. The Ford brand suffered a 6.3-percent dip in sales, but brand transaction prices increased $2,000, while a Lincoln sold for $8,700 more on average. General Motors sold more cars and sold them for more money; overall GM transaction prices rose four percent, or $1,270, while a GMC traded hands for seven-percent more than in January 2017 and a Cadillac got $2,300 more on average. Of KBB's listed automakers, the Volkswagen Group got the most of out its customers, transaction prices rising at the German automaker by 5.6 percent to $42,243 in January 2018 compared to a year earlier. American Honda followed with a 4.3-percent increase to $28,991, GM in third at 4.1 percent to $40,313. Find your next car at Autoblog using our new and used car listings or the Car Finder tool. Broken out by segment, minivans rocked the table, transaction prices leaping by 7.9 percent to $35,380 compared to January a year earlier. Luxury cars boasted the next-highest rise, at 3.6 percent to $58,533.
