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.

NHTSA could add 1M cars to GM recall

The Detroit Free Press is reporting that the National Highway Traffic Safety Administration may expand a recall campaign for faulty brake lamps. The agency is currently looking into complaints that certain 2004-2011 Chevrolet Malibu models as well as some 2007-2009 Saturn Aura sedans may have brake lights that do not illuminate when the driver presses the pedal. Alternatively, the lamps may also illuminate without input from the driver. General Motors recalled 8,000 Pontiac G6 models from the 2005 model year for the same problem, and NHTSA is currently investigating whether to add 550,000 more G6 models built between 2005 and 2009 to the list for the same issue.
In addition, investigators are currently examining 97 complaints from Malibu and Aura owners with the same trouble. If NHTSA adds those models to the recall campaign, more than one million units could be covered. GM, meanwhile, says there have been no accidents or injuries as a result of the problem.

Jaguar I-Pace vs. Tesla Model 3 and other EVs: How they compare on paper

The 200-mile club of electric vehicles is really growing. The most recent member is the Jaguar I-Pace, the company's first pure EV. It promises luxury, performance, style, and most important, good range. Nearly as recent is the Hyundai Kona EV, and while it doesn't promise luxury or performance like the Jaguar (it's also smaller), it does pack impressive range. With the introduction of both of these electric cars, we thought we would see how they compare against each other, and the other two big names in high-capacity electric cars: the Chevy Bolt EV and the Tesla Model 3. This isn't intended to be a direct, apples-to-apples comparison, as the four are quite different. If anything, they break into two groups: bigger and more luxurious, and smaller and less expensive. Then again, the number of vehicles with this electric range is small and comparisons to EV's with less range wouldn't be too kind to the other guys. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools. Horsepower and torque There is one clear winner here, and that's the Jaguar I-Pace. It packs a whopping 394 horsepower and 512 pound-feet of torque. That comes through a pair of electric motors (one at the front, another at the rear) that provide the Jag with all-wheel drive, the only one of these vehicles to offer it (at the moment). Altogether, it allows the I-Pace to have the best 0-60 mph time of 4.5 seconds. At the other end of the spectrum is the Hyundai Kona EV. It's front-drive, like the Bolt EV, and has effectively the same amount of horsepower as the Chevy at 201 horsepower, but its 0-60-mph time is almost a second slower. And the low-range version of the Kona, excluded because it doesn't go more than 200 miles between charges, is slower still. The Tesla Model 3 is the only vehicle with rear-wheel drive, and with a 0-60 mph of 5.1 seconds for the Long Range model, it is still very quick. Range and energy use Frequently, the all-consuming question with electric cars is, "How far can I go on a charge?" And to go the farthest, you need the long-range Tesla Model 3. It can go 310 miles. It has the added advantage of being able to use the network of Tesla Supercharger stations, though they are pay-per-use with the Model 3. Even the lower capacity Model 3, with just 220 miles of range, can use these stations.
