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.

Chevy Express, GMC Savanna reportedly ending production for 2025

The oldest commercial vans on the market may only have a few years left, according to a report from Autoweek. The news outlet cited a "competitive analysis source" in saying that the Chevy Express and GMC Savanna commercial vans would be discontinued after the 2025 model year. They would then be replaced by a new electric van, likely Ultium-platform based, for the 2026 model year. We reached out to GM for comment, and this is the official statement sent to us: "We have said in the past that as part of GM’s larger EV acceleration plans that we will add two new vehicles to our commercial portfolio. The first is a full-sized battery electric cargo van and the second is a medium-duty truck that will put both Ultium and our Hydrotec hydrogen fuel cell technology to work. We have not disclosed timing, names or shared any other details, so any articles reporting more are purely speculative." The GM vans are mighty old, having been introduced for the 1996 model year. They've barely changed since then, having received just some facelifts and updated powertrains over the years. And with GM's electrification plans, we're not surprised that these vans will be on the way out. We do have some disagreement about the reported timeline for replacement, though. We suspect that the upcoming electric vans will overlap with the old vans for at least a year. The reason being that there are a lot of these vans on the road, and there are a lot of pieces of equipment that fit them. Box vans, buses and more have components that have been designed for the Express and Savanna. If you're a fleet that has invested in these components, you might not be ready to shift over to a whole new platform. So GM will probably want to give fleet buyers one last opportunity to replace any old vans before committing entirely to a new electric van platform. It will also be interesting to see what kind of market the GM electric vans enter. Ford already has its electric Transit on the way, and Stellantis will be launching the Ram ProMaster electric van next year. Those are both based on existing gas-powered vans. And GM itself has already delivered the first of its larger BrightDrop EV600 electric vans to FedEx. The coming GM vans will likely be new platforms, which could give them performance and range advantages, though the Ford and Stellantis vans will have the advantage of being compatible with equipment for the gas variants.

GM says its electric pickup truck is 'in development'

GM President Mark Reuss just reiterated the company's support for an electric pickup project. He also claimed that GM is going to be selling its future electric cars at "very average transaction prices" during the same conference with Wall Street analysts. Previously, Mary Barra informed the world of GM's electric pickup truck aspirations, but didn't tell us anything else. Reuss says the truck is already in development, though, according to a Wards Auto report. "We will have a complete electric lineup, including a pickup truck that's in development," Reuss said. This comment marks the second time GM has gone on the record about its intentions to bring an electric pickup to market. Additionally, Reuss said GM's third-generation global EV platform will be used to help develop the electric pickup. This platform was recently announced to underpin at least 20 new EVs from GM in the future — the platform itself is slated to be unveiled in 2021. Of course, this platform will be flexible and modular to allow various body styles to be used with it, a truck being one of those. Reuss still hasn't said what GM brand the pickup will be sold under, or what class of truck it will be. GM thinks this new platform is also going to be what helps it drive down the cost of building EVs. "We'll reach parity a lot sooner than people think," Reuss said comparing EVs to traditional gas-powered engines. "We're driving down the cost of batteries and the whole EV in general." As for electric pickups, Ford is also deep in development of its own electric F-150. However, neither of these truck projects have official timelines on them, so we can't say when they'll hit the market. For now, the cross-town rivals are both in development with their respective electric pickups. Even further across town is Rivian (in which Ford just invested half a billion dollars), a company that says its electric R1T pickup is right around the corner, with the official due date being end of 2020 for the time being.
