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.

Supercharged 2015 Chevy Corvette Z06 takes the C7 beyond the ZR1

The Z06 is just about everything we got in the last ZR1, but better.
After a bright-yellow false start, here is the real thing: the fourth-generation, 2015 Corvette Z06. If Chevrolet makes a ZR1 version of the C7 Corvette, it's going to be absolutely mega, because the Z06 is just about everything we got in the last ZR1, but better.

GM's Buckle to Drive teen safety feature comes to more models for 2021

In 2014, GM announced a feature called "Belt Assurance," which would prevent a vehicle from being shifted out of park until the driver and front passenger had buckled their seatbelts. Initially launched on certain fleet vehicles in 2014, the feature rolled out as a free option on the 2015 GMC Sierra, Chevrolet Colorado, Cruze and Silverado. At the time, GM said it would push Belt Assurance to more models if customers took to it. That appears to have happened; come 2019, GM repackaged Belt Assurance as Buckle to Drive, part of the automaker's Teen Driver System that bundled tech such as geofencing and speed limit warnings to help parents keep track of their children's driving habits. In that implementation, the system only works when Teen Driver Mode is activated, locking out the shifter and muting the radio for 20 seconds or until the seatbelts are buckled, whichever comes first. The system shows a visual warning in the gauge cluster, too.  For this model year, the Teen Driver System came standard on 10 Chevy models, but Buckle to Drive was only allotted to the Colorado, Malibu and Traverse. Later this year, the 2021 Camaro will join the Chevys outfitted with the Teen Driver System and will get Buckle to Drive in addition. GM Authority reports that for the 2021 model year, Buckle to Drive will also be picked up by the Cadillac CT4 and CT5. Previously, the Cadillac ATS, CTS, Escalade and XTS came with the Teen Driver System, but three out of those four vehicles are no more, and the 2021 Escalade makes no mention of the Teen Driver System nor Buckle to Drive among its safety features. Elsewhere around the GM empire, the Buick Envision and Encore GX include the Teen Driver System, as do six GMC vehicles, but it's not clear when any will be upgraded with Buckle to Drive. The tech could help save numerous teenagers' lives. On its page of teen crash facts, the Centers for Disease Control and Prevention writes that roughly 300,000 teens between the ages of 16 and 19 ended up in emergency rooms to treat crash injuries in 2017. Furthermore, "only 58.8% of high school students always wore seat belts when riding as passengers," and, "Among young drivers aged 15-20 who died in car crashes in 2017, almost half were unrestrained at the time of the crash (when restraint use was known)."
