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.

Opel's version of the Chevy Bolt will confuse people at Paris Motor Show

Two things are now official. First, Opel will reveal the Ampera-e, or the European version of the Chevrolet Bolt, at the Paris Motor Show in October. Second, General Motors has outdone itself in brand confusion, topping the Bolt/Volt ridiculousness. Opel isn't giving a single-charge range for the Ampera-e but the company is promising a "significantly longer range" than other electric vehicles. The Bolt is estimated to have a 200-mile range on the EPA scale, so whatever the Opel achieves on the European cycle will be done with the same batteries and motor as the Chevy. Opel is also looking to appeal to the auto enthusiasts with other factoids, which are basically just Bolt stats translated into metric. For instance, the Ampera-e will be able to go 0 to 50 kilometers per hour (which is 31 miles per hour to us Americans, but we're talking Europe here) in just 3.2 seconds. And for those looking to stay connected, as many as seven mobile devices can attached to the car's wireless hot spot. GM said in February that the European of the Bolt would be available across the pond next year, so the most recent bit of news isn't shocking. Still, General Motors continues to create confusion between all-electric Bolt and the extended-range plug-in Volt. It's already been reported that the Korean symbol and pronunciation of what is "B" in English is identical to the English "V," meaning that there is no difference between "Bolt" and "Volt" in that country (though there are no plans to sell the Bolt in South Korea as of yet). Now, in Europe, they're taking the name they used to use for the European of the Volt — Ampera — and merely adding an "-e" at the end of it. For those looking to be less confused, take a look at Opel's press release here.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.
