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.

There's an impending shortage of new trucks in America's heartland

URBANDALE, Iowa — Jerry Bill is worried the novel coronavirus could hurt business at the Des Moines auto dealership he runs, but not because of a shortage of buyers for the big Ram pickups on his lot. "Our biggest issue will be if we don't get more inventory," said Bill, general sales manager of Stew Hansen Chrysler Dodge Jeep Ram, which sells around 2,700 new vehicles a year in Urbandale, a suburb of Iowa's capital Des Moines. After a drop in sales in April when consumers stayed home, Bill expects pickup truck sales to end May similar to where they were a year earlier. And if demand remains strong, Bill said he will run out of popular models in June. Fiat Chrysler began slowly restarting Ram truck assembly lines on Monday after a two-month shutdown. The U.S. economy contracted in the first quarter at its sharpest pace since the Great Recession of 2007-2009 because of lockdown measures aimed at slowing the spread of the coronavirus. Economists warn the second quarter will be much worse. Still, far from the lockdowns of states like New York, Michigan or Ohio, dealerships like Stew Hansen have provided FCA and Detroit rivals General Motors and Ford a rare bright spot: strong sales of pickup trucks in America's heartland. Overall U.S. sales of cars and light trucks crashed to the weakest pace in 50 years last month. But sales of big Detroit brand pickups, particularly in southern and western states less affected by the outbreak, significantly outperformed the market, industry executives and analysts said. Pickup trucks are one of the most profitable automotive segments in the world. They account for a huge portion of the Detroit automakers' profits and formed a huge lure for Peugeot, which expects to merge with FCA by early 2021. The pressure is now on to boost pickup truck production and send vehicles to dealers in parts of the country with dwindling supplies. That is particularly true for GM, which is running short of certain truck models after losing 40 days of production to a strike last fall. "If you don't have what someone wants, they can choose to go to another brand," said Cox Automotive analyst Michelle Krebs. 'Easiest swap ever' Detroit automakers in March rolled out large discounts — such as interest-free loans for seven years — to keep vehicles rolling off dealer lots.

Recharge Wrap-up: Chevy Volt promos, Audi e-gas partnership

GM is offering promotions on the 2017 Chevrolet Volt. As dealers receive the first shipments of the new model year of the Volt, the automaker is giving customers in certain areas (California, Connecticut, Massachusetts, Maryland, Maine, New Hampshire, New Jersey, New York, Oregon, Rhode Island, and Vermont) $1,000 cash back on their purchase. GM Financial is also offering lease discounts for a limited time, and trade-ins may be eligible for even more money back. State and federal incentives could add up to make the new Volt quite the bargain for the right customer. Read more at Clean Technica. The UK's potential exit from the European Union could mean tighter emissions regulations, potentially even in the UK. While Britain has fought against the EU on stricter rules, the "Brexit" could leave officials in Brussels free to strengthen air quality laws. The UK, despite giving up its seat at the table, would still be beholden to some rules as a member of the European Economic Area free trade agreement. British voters vote on a referendum to leave the EU on June 23. Read more from Bloomberg Business. Daimler will refrain from investing in battery pack production with other automakers for the time being. Daimler CEO Dieter Zetsche cites an overabundance of battery production, saying, "Contrary to the expectation four or six years ago when everyone thought that the cells would be a rarity that could even be used as a tool of industrial policy, there is de facto a massive overcapacity in the market today and cells have become a commodity." Daimler recently shuttered its own lithium-ion battery production due to high costs and low demand. Read more from Automotive News. Audi is partnering with the Viessmann Group to increase e-gas production using a new biological process. Audi has been making the renewable fuel through a two-part process of electrolysis (splitting water into oxygen and hydrogen) and methanation (reacting hydrogen with CO2 to make synthetic methane). The new biological process uses microoganisms to absorb hydrogen and CO2 to make methane. The process requires lower temperature and pressure, and doesn't require high concentrations or purity of CO2. Read more in the press release below.
