GM is training more first responders for EV emergencies in the U.S. and Canada

GM is training more first responders to be able to handle emergencies involving electric vehicles. The automaker is "significantly expanding" its EV First Responder Training program in the United States and Canada as electric vehicle sales continue to grow. Its initiative will primarily focus on training firefighters and equipping them with the necessary knowledge about full electric vehicle technologies. GM says it's hoping to dispel misconceptions when it comes to handling EVs in emergency situations. One of those misconceptions is that water is dangerous around EV batteries — turns out the recommended way to put out lithium-ion battery fires is by using copious amounts of water.  Andrew Klock, a senior manager of education and development at the National Fire Protection Association (NFPA), said: "The best way for the public and private vehicle fleet owners to rapidly adopt EVs is to train firefighters and emergency responders on how to handle incidents involving battery powered vehicles. The fire service has had more than 100 years to gain the knowledge needed to respond to internal combustion engine fires, and it is critical that they are now educated on EV safety." The NFPA held trainings of its own that had benefited 300,000 first responders, but it believes more than 800,000 members of the community still need further training.   GM previously piloted the program in southeast Michigan, but now it's conducting training events across Michigan and in Fort Worth, Texas, as well. Later this summer, it's bringing the program to metro New York City and Southern California. Participants will have to attend four-hour sessions, with up to two per day, held in various venues, such as fire houses and dealerships. Interested first and second responders can register through the program's dedicated website and earn a certificate from the Illinois Fire Service Institute if they score higher than 70 percent on the learning assessment by the end of their training.  The automaker already has a few EV models on the market, including the Chevy Bolts, the GMC Hummer EV and the Cadillac Lyriq. It has huge electrification plans for the future, though, and training responders could help make potential customers more receptive to the idea of switching to electric vehicles. GM aims to launch 30 EV models by 2025 and to exclusively sell EVs ten years after that. Related video: Green Cadillac Chevrolet GM GMC Safety Electric

2020 GMC Sierra 2500 HD and 3500 HD spied on public roads

We saw spy shots of the Chevrolet Silverado HD a short time ago, and now it looks like GM has got the 2020 GMC Sierra Heavy Duty trucks running around in public too. The one we're looking at here appears to be a 2500 Denali Crew Cab, distinguished easily by the same Denali grille on the 2019 Sierra 1500. Aesthetic differences between the front fascias on the 1500 and 2500 HD are small, but the 2500 is a bit more muscular in the hood and lower trim treatment. GMC doesn't look like it's hiding a whole lot with this camouflage, since the sheets over the grille and headlights are mostly transparent. The black tarp over what appears to be a hood scoop leads us to believe it will have the same type of hood design as the 2018 HD. Other interesting bits revealed here are around the rear of the pickup. We can see the same interface for the MultiPro six-way tailgate on this truck as the 1500, so at least the Denalis will have the trick tailgate (we'd expect every trim to have it, though). Just like we saw on the Silverado, the Sierra HD gets the stepside feature just ahead of the rear wheels. LED taillights are clearly visible through the thin veiling, and GM's rear steps remain as well. in addition to this 2500 HD, our spy photographers also caught a 3500 HD model. This one isn't a Denali, as the grille shows its hand again. The grille is different than any of GM's designs on the new trucks we've seen thus far, actually. GMC showed us a teaser of what a new Silverado HD grille would look like months ago, but this differs even further than that. It looks rather minimalistic under the sheet for now, with strong horizontal slats. The actual shape and design of the truck is revealed for the most part, since it's just wearing a thin body wrap. Its mirror design appears to be different from last year's, as the arm is completely solid. A sidestep right in front of the rear wheels carries over from the 2500 HD too. We imagine both this truck and the Silverado HD will debut early next year during auto show season. Related video: This content is hosted by a third party.

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.
