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: BYD unveils 60-ft electric bus, Honda sticking with hybrids in Europe

BYD has debuted a 60-foot electric bus at the American Public Transportation Association Expo in Houston, TX. The Lancaster bus, as it is called, has a 120-passenger capacity and can drive over 170 miles on a single charge. The articulated bus features low floors and no steps, thanks to in-wheel hub motors. BYD also displayed a 40-foot electric bus that drove the 1,500 miles to the show under its own power (recharging along the way, of course). Read more in the press release below. Honda says it will continue to sell hybrids in Europe, despite the fact that it has stopped selling the CR-Z and Insight due to slow sales. "Our focus at the moment is on our 1.6-liter diesel but we haven't forgotten about hybrid technology," says Honda Europe's Philip Ross. Honda will sell the next-generation Fit (badged as the Jazz) in Europe when it launches next summer, and will sell the next-gen hybrid version beginning in 2016. Honda sold 4,500 of the Jazz hybrid in Europe last year. Read more at Automotive News. XL Hybrids is selling its XL3 Hybrid Electric Drive System in California. The news comes after the California Air Resources Board issued an executive order allowing the aftermarket hybrid conversion for 2012-2014 Chevrolet Express and GMC Savana vans.

NRG eVgo has finished installing 60 charging stations at the Sony Pictures Entertainment studio lot and offices in Culver City, California. The Level 2 chargers, which will be managed by NRG eVgo, allow employees to charge their EVs during the workday. An average of 90 EVs and PHEVs park at the studio headquarters every day, thanks in part to Sony Pictures' Alternative Vehicles Incentive program for its employees. Learn more in the press release below. Pennsylvania's Public Utility Commission will allow operators of EV charging stations to set prices based on kilowatt hour usage. This change ensures that drivers pay for the actual energy they use, rather than the time they spend charging, since different cars can charge at different speeds. Car Charging Group has already begun using the per-kWh fee structure at its charging stations throughout the state. Other states that allow kWh pricing are California, Colorado, Florida, Hawaii, Illinois, Maryland, Minnesota, New York, Oregon, Virginia and Washington. Read more in the press release below.

Fernando Alonso just misses qualifying for Indy 500 on first day

Former Formula One world champion Fernando Alonso will need a clutch run on Sunday to qualify for the Indianapolis 500 on May 26 after he failed to seal a guaranteed spot on Saturday. The Spaniard tried fives times to put his McLaren Racing Chevrolet in the top 30, but wound up one spot short. He can make the 33-car field only through a six-car shootout on Sunday that will determine the race's final three drivers. "We have another chance to be in the race," Alonso, who is seeking to make his second Indy 500 field, told IndyCar TV. The Spaniard twice got inside the top 30 but both times was bumped outside the mark, with JR Hildebrand and Graham Rahal the final two drivers to seal qualifying spots. Britain's Pippa Mann will be the only woman in the race, qualifying 30th in 227.244 mph. Race positions 10-30 were determined during the day-long qualifying with Saturday's nine fastest drivers set to return on Sunday to decide pole. Spencer Pigot, driving the Ed Carpenter Racing Chevrolet, led qualifying with a four-lap average of 230.083 mph. He was followed by 2018 winner Will Power of Australia (230.081) and Simon Pagenaud of France (229.854). The troubles for Alonso, whose top four-lap average was 227.224 mph, were exacerbated by a punctured tire in his first qualifying run. "That didn't help," Alonso told reporters. "But, obviously, our performance has been quite bad all week. Quite poor." The Spaniard crashed his Chevrolet in practice on Wednesday and missed nearly two full days of practice while a backup car was prepared. He returned on Friday. Alonso said he was worried the McLaren team was "not ready for the challenge." "We've been slow. You see Juncos Racing crashing yesterday and being ready at 6 o'clock. That's impressive," he said. "For us, we've been a little bit slow on everything." Alonso is bidding to join Graham Hill as the only drivers to achieve the 'Triple Crown of Motorsport' with an Indy 500 victory. He previously won the Monaco Grand Prix and Le Mans 24 Hours race. He also won two Formula One drivers' titles.
