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 61k more vehicles in three campaigns

Following a stop-delivery order for its new midsize trucks and a rash of recent recalls, General Motors is issuing three more campaigns covering 60,575 vehicles in North America with 57,182 of them in the US. As of October 1, the automaker has issued a total of 74 recalls (see the ridiculously long chart to the right) this year covering 26,495,070 units in the US.
The largest campaign covers 46,873 examples in the US of the 2008-2009 Pontiac G8 and 2011-2013 Chevrolet Caprice Police Patrol Vehicle imported from Australia. It's possible for the driver's knee to hit the key and make it move from the "Run" to "ACC" position while driving. GM says its Holden division is developing a fixed-blade key that's supposed to fix the problem by only allowing it to rotate toward the "On" position. There has been one crash caused by this fault but no injuries or fatalities.
The second recall is for 10,005 units of the 2004-2007 Cadillac CTS-V and 2006-2007 Cadillac STS-V because "the fuel pump module electrical terminal may overheat." This can cause a flange to melt and allow the pump to leak fuel. GM specifies that the remedy for the CTS-V is replacing the fuel module and fuel tank jumper harness, but it doesn't specify how the STS-V is being repaired.

Electric Cadillac Lyriq, Chevy Bolt EUV and more GM electric cars are on the way

GM’s murky and somewhat secretive electric car plan is falling into place, as the company dumped a massive amount of information about whatÂ’s in the pipeline at an event at its Warren, Michigan campus today. New EVs are going to be popping up across the GM brand lineup, with new entries from Chevrolet, Cadillac, GMC and Buick in progress. We also learned some big news about GMÂ’s new Ultium battery tech today, but check out this story for all of those nitty-gritty details. The electric vehicle onslaught will begin with the Cadillac Lyriq, an electric SUV thatÂ’s already been teased out. Naming it the Lyriq is the news today. No explanation for the name was provided, so weÂ’ll have to wait for April to learn more. GM didnÂ’t specifically say if the Lyriq would be launched at the NY Auto Show, but that show (assuming coronavirus doesnÂ’t cancel it) will begin on April 8 this year. Next up in the order of events is the GMC Hummer electric truck that we know will be launching on May 20. This truck will use GMÂ’s modular Ultium battery technology. However, the wait to buy a GMC Hummer will be a long one, as the truck isnÂ’t going to dive into production until fall 2021 at GMÂ’s Detroit-Hamtramck plant. GM revealed that its new modular Ultium batteries can be configured anywhere from a 50 kWh pack to a 200 kWh pack depending on the application. Range is estimated to be about 400 miles on the upper end with the largest battery pack, and GM continues to boast about a 0-60 mph acceleration time of three seconds. Charging estimates for the Ultium battery-equipped Hummer EV were also provided. GM says its truck platform will have 800-volt battery packs and be capable of 350 kW fast-charging. Time estimates werenÂ’t given, but those numbers suggest the truck will be a rapid charger. The Hummer truck on hand, which was the same that previously starred in GMC's Super Bowl spot, showed off removable roof panels that store in the frunk, as well as what appeared to be a version of GMC's Multi-Pro tailgate. It also featured sail panels on the sides, similar to those in front of the bed of the Chevy Avalanche. In addition to the Hummer, expect to see a couple Chevys launching. GM says the refreshed Bolt EV will be launched “in late 2020” with a refreshed interior and what appear to be thicker front seats.
