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.

Recharge Wrap-up: Cadillac CT6 Plug-In on sale in China, Oregon utilities spur EV adoption

The Cadillac CT6 Plug-In is now available in China. The luxury plug-in hybrid sedan uses a turbocharged 2.0-liter engine plus two electric motors, which give the car a 0-62 mph time of 5.4 seconds. Its liquid-cooled 18.4-kWh lithium-ion battery pack gives the car an all-electric range of 50 miles, with a total range of 581 miles. Cadillac offers a 200V charger with the CT6 Plug-In, which provides a full charge in less than five hours.

Two Oregon utilities are launching a program to increase EV adoption. Portland General Electric (PGE) will build six charging locations, each with up to four dual-standard fast chargers. PGE will also build and operate charging sites for electric buses, freeing up money for Portland's TriMet transit agency to spend on the actual buses. Pacific Power will also build public EV chargers, and lower some electricity rates for operators. Both companies will also work to inform the public about the benefits of electric mobility. Oregon utilities are required to stop using coal by 2030, and use 50 percent renewable energy by 2040, which will make EVs even cleaner. Read more at Green Car Reports. Continental says a shift to EVs will cost its company jobs. The automotive parts supplier's CEO, Elmar Degenhart, says that while the company will need to cut production jobs, those will be offset at least in part by the creation of new positions related to electric mobility. "There is enough time to design the process such that the blow is softened and major pain can be avoided," says Degenhart. Some 30,000 jobs at Continental are tied to combustion engines.

Cadillac introducing V2V communications on 2017 CTS sedans

While Audi has introduced vehicle-to-infrastructure technology in select cars in select cities, Cadillac is focusing on vehicle-to-vehicle (V2V) communications, and it all starts with the CTS sedan. Starting this month, the company will be adding V2V equipment to 2017 models. The feature will be standard on cars in the US and Canada. These V2V devices will allow these new Cadillacs to communicate with each other up to 980 feet away. The cars will be able to transmit and receive information on speed, direction, and location. An example of how this data can be used is in detecting a car coming up a side street that could pose a possible collision risk. The cars will also be able to transmit data about brake use, hazard lights, and low traction situations for advance warning of hazards. The warnings can be displayed on the instrument panel and heads-up display. Currently, the system only communicates with other CTS sedans equipped with the technology. According to Chris Bonelli at Cadillac part of the reason is that the CTS will be the only car with the equipment on US roads at the moment, but it also isn't currently set to communicate with other cars if they were to be offered right away. However, he said that the company is absolutely willing to work with other companies to make the system compatible if or when other cars are offered with the technology. This V2V system also doesn't send data to any sort of network, instead only communicating with nearby cars. For the time being, this precludes the possibility of receiving road condition information from cars that are farther away. But as Cadillac points out, it should work under any conditions with no delay since it isn't dependent on information from a network. As far as security is concerned, Bonelli told us that the Cadillac system does have firewalls and other security measures to keep it protected from interference. He also said the cars don't store any data they receive. In addition, none of the data could be used to identify a particular person. The cars use a radio frequency set aside by the government for this use. The introduction of this technology also puts Cadillac well ahead of proposed legislation by the Department of Transportation. The organization wants this type of short-range V2V communications equipment to be a standard feature by 2023, believing the technology could prevent many injuries and deaths due to crashes.
