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: Lexus CT 200h is NWAPA's favorite hybrid, 'No Charge to Charge' in LA

The Northwest Automotive Press Association (NWAPA) has given the Lexus CT 200h its Favorite Hybrid title. It named the compact luxury hybrid its favorite of 2014 at its Drive Revolution in Portland (where it also named the new Volkswagen Golf TDI the Northwest Green Car of the Year). According to NWAPA president Nik Miles, the CT 200h earned the honor for "impressive combination of state-of-the-art small car luxury and hybrid technology." For 2014, the Lexus CT200h got an updated front end, including the spindle grille we've been seeing on new Lexus vehicles, plus a redesigned steering wheel and sliding sun visors.

Chevrolet started including stop-start technology standard in Malibus equipped with the four-cylinder engine. Chevy has sold about 83,000 of that model, so 97 percent of 2014 and 2015 Malibu sales include stop-start. Now, that technology has made its way into the 2015 Impala. With drivers idling an average of 16 minutes a day, stop-start can significantly reduce harmful emissions and save fuel. According to Navigant Research, we can expect annual sales of cars equipped with stop-start technology to surpass 55 million by 2022. Read more in the press release below. Nissan Leaf customers in Los Angeles will get access to free charging beginning August 15. Nissan is extending its "No Charge to Charge" promotion to LA, which will allow customers to charge at public charging stations at no cost. Leaf customers - including those who bought or leased their car from the participating dealerships on or after July 1 - will get an EZ-Charge card, allowing them to use ChargePoint, Blink, CarCharging, AeroVironment and NRG eVgo chargers for free.

California will get six all-electric school buses for three school districts as part of a demonstration program. The California Energy Commission awarded a grant of $1.4 million for the program to National Strategies LLC; this is in addition to a $2.2-million grant from the South Coast Air Quality Management District. The EV buses use vehicle-to-grid technology, allowing them to sell energy back to the grid when it is needed.

Recharge Wrap-Up: LAPD gets Zero MMX, Chevy's new inverter, Hyundai Tucson's new powertrains

Some police in Los Angeles will be riding Zero MMX electric motorcycles on duty. The LAPD is adding the fully electric police/military all-terrain bikes to its patrol fleet. According to Officer Steve Carbajal of the department's off-road unit, "It costs less than 50 cents to charge compared to using gallons of gas, maintenance is simple, and the community appreciates how quiet they are." The electric bikes, with their lack of noise and a headlight the rider can turn off, also have the benefit of stealth, giving the officers what Carbajal calls "an added tactical advantage." The MMX also has swappable batteries, is designed for quick ignition and has power reserve capabilities so the rider won't be caught with a dead battery while chasing down a perp.

Drivers of classic cars in Detroit were able to fill up their tanks at gas prices corresponding to their model year, thanks to a promotion by Hagerty Insurance for National Collector Car Appreciation Day on July 11. That meant prices from 21 to 90 cents a gallon, as the cars that showed up ranged from the years 1929 to 1989. That's about as affordable as charging your EV.

GM is about two-thirds of the way through the development of the new inverter, which should be ready in January 2016. The inverter, which has a peak output of 55 kilowatts a continuous output of 33 kilowatts, will be adaptable for use in other GM vehicles. Chevrolet is working to reduce the Volt's production costs by $10,000 per vehicle, which should make it more affordable, and the new inverter could help reach that goal should it make its way into the car.
