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.

GM recalls 51k Enclave, Traverse, Acadia crossovers over fuel gauge inaccuracy

With all eyes fixed on General Motors in the wake of the ignition recall debacle, the auto giant has been carefully calling in a wide array of vehicles to fix anything and everything that could prove problematic. Just the other day it issued two separate recalls - one concerning the Cadillac SRX and another its heavy-duty pickups - and now it is issuing another.
This time the vehicles in question are the Buick Enclave, Chevy Traverse and GMC Acadia, three fullsize crossovers based on GM's Lambda platform. In an estimated 51,640 units manufactured between March 26 and August 15, 2013, the engine control module has been found to incorrectly display the level of fuel in the tank.
As a result, owners are being notified to bring their vehicles in to their local dealers to have the ECU reflashed to fix the problem. View the full details in the announcement below from the National Highway Traffic Safety Administration.

2020 GMC Sierra HD pricing announced

Just as with its Chevy twin, pricing for the 2020 GMC Sierra HD has been revealed. Unlike the Chevy, though, prices haven't dropped across the board. The ultimate base prices for the 2500 HD and 3500 HD are technically less than the 2019 models at $37,195 and $38,395 respectively, but that's because those are the reintroduced regular cab models. Matching up the body styles of the last year's cheapest Sierras with their new equivalents, and the prices have crept up a few hundred dollars. But the next highest trim level, SLE, drops in price by nearly $2,000 between equivalent trucks. Equivalent SLT trucks are up nearly $2,000 each, though, and the base Denalis have gone up by about $7,000. This is due in part to the 2020 Sierra Denali no longer being offered with two-wheel drive. Comparing the old and new four-wheel drive models, the price is still up by about $4,000. While the new Sierra HD is only more affordable than the last one in certain circumstances, they all feature more capability. The standard 6.0-liter gas-powered V8 makes an extra 41 horsepower and 84 pound-feet of torque than the old one for a total of 401 horsepower and 464 pound-feet of torque. The 6.6-liter diesel V8 still makes 445 horsepower and 910 pound-feet of torque, but it now gets a 10-speed automatic transmission. Maximum fifth-wheel towing has increased, too. For the 2500, that number jumps from 15,400 pounds to 18,500 in the new model. For the 3500, fifth-wheel towing goes from 23,100 pounds to 35,500 pounds for the new truck. And of course, you can get GMC's fancy MultiPro tailgate on the new Sierra HD. One final note on the Sierra HD's pricing: it has the highest base price of the full-size heavy duty trucks. The Ford F-250 Super Duty is the cheapest at $34,745 and is closely followed by the Ram 2500 at $35,090. The full range of GMC Sierra HD pricing is listed below: Sierra 2500 HD Regular Cab Sierra: $37,195 SLE: $41,595 Double Cab Sierra: $39,795 SLE: $43,595 SLT: $52,195 Crew Cab Sierra: $41,595 SLE: $45,395 SLT: $53,995 AT4: $59,295 Denali: $65,295 Sierra 3500 HD Regular Cab Sierra: $38,395 SLE: $42,795 Double Cab Sierra: $41,195 SLE: $44,995 Crew Cab Sierra: $42,795 SLE: $46,595 SLT: $55,195 AT4: $60,495 Denali: $66,495 Update: The estimation of price difference between 2019 and 2020 Sierra Denalis has been corrected. Additional clarification of Denali price changes has also been added.
