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.

MotorWeek Retro Review revisits 1984 Corvette

MotorWeek's Retro Reviews are always a great glimpse into the cars of yesteryear. However, the newly uploaded look back at the 1984 Chevrolet Corvette is an absolute treasure trove for any auto history buff. This is a full episode of the show from the '80s, and it's dedicated to all of the details about the newest 'Vette to hit the market at the time. Beyond just the usual drive and an in-depth walk around, one of the major highlights here is a brief look at some on the concepts that eventually resulted in the fourth-generation Corvette of 1984. The C4's shape harkens back to sketches from 1978, and there even shots of early clay models that led the way for the design. MotorWeek also takes a tour through the Bowling Green, KY, factory for a detailed inspection of the entire production process. John Davis repeatedly calls the Corvette "the plastic fantastic" during the episode, and he can't find too much negative to say about being behind the wheel of the then-new coupe. See how it stands up to your own memories in the clip above.

McLaren and Alonso will use Chevy engines at Indy 500

Fernando Alonso will have a Chevrolet engine in his McLaren when the double Formula One champion attempts to win next year's Indianapolis 500 in his second attempt, the British team announced on Tuesday. The 37-year-old Spaniard led 27 laps last year on his debut at The Brickyard in a Honda-powered Andretti Autosport car before retiring with an engine problem with 21 laps to go. The 2018 Indy 500 winner, Australian Will Power, won with Chevrolet-powered Team Penske last May. "Having Chevrolet power behind me means we're putting ourselves in the best possible position to compete at the front," said Alonso in a McLaren statement. The double Monaco Grand Prix winner, who won the Le Mans 24 Hours with Toyota this year, left Formula One at the end of the season last month and is targeting Indianapolis as the final part of the "Triple Crown of Motorsport": winning the Formula One championship (or Monaco), Le Mans and the Indy 500. The late Briton Graham Hill, also a two-times Formula One champion who died in 1975, is the only one to have done it, completing the triple in 1972.Reporting by Alan BaldwinRelated Video: Motorsports Chevrolet McLaren Racing Vehicles IndyCar
