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.

2019 Cadillac Escalade ESV Drivers' Notes Review | Old, but not antiquated

When the Cadillac Escalade debuted 20 years ago, car-based crossovers were just getting their start. The Escalade was and still is basically a Chevy Tahoe with new styling and a nicer interior. That's especially true today, as our test car has an interior that looks like it was lifted straight from a Cadillac CTS rather than a Chevy Silverado. Crossovers may be more comfortable and fuel efficient, but they can't hold a candle to towing and payload capabilities of a body-on-frame SUV. If you need to haul seven people and a full-size Airstream in quiet comfort, few options are better than the Escalade. This week, our tester was a long-wheelbase Escalade ESV. That means substantially more room both behind the third row and with the seats folded. The Premium Luxury trim sits in the middle of the lineup, but it still comes with a lot of goodies. Features include a Bose audio system, a digital instrument cluster, a heads-up display, heated and cooled leather seats, a heated steering wheel, tri-zone climate control, Magnetic Ride Control and a stout 6.2-liter V8. Options include upgraded leather for $2,000 and polished 22-inch wheels for $600. All in, this Escalade was just shy of $100,000. Editor-in-Chief Greg Migliore: The Escalade is arguably Cadillac's best vehicle. It's a bold, body-on-frame SUV that feels decadently all-American. The Escalade is still contemporary even though it's been years since the ute has had a major redesign. I enjoyed a couple nights in this luxury bruiser. The V8 is powerful, and the 10-speed is a smart improvement. The command seating position is always welcome for me. The interior is nicely laid out, and the materials all look and feel upscale. Not a huge fan of Cadillac's touchscreen (no longer officially called CUE), but it seems to be getting better or I'm getting used to it. Love the Escalade's exterior design. It's dramatic, imposing and gives Cadillac something that's a true style-leader. All that being said, I'll be interested to see how Caddy iterates the Escalade. The Lincoln Navigator is an excellent product and a worthy adversary. Cadillac would be wise to keep its SUV flagship fresh. Senior Editor, Green, John Beltz Snyder: I was not excited to get into the Escalade. This is really not my cup of tea. I used to love the Chevy Suburban, but that fondness has languished as my tastes evolved as these huge vehicles have modernized, losing the charm that drew me to them when I was younger.

Diesel engine will be a no-cost option on 2021 Cadillac Escalade

Pricing for the redesigned 2021 Cadillac Escalade was revealed yesterday, with the various trim levels ranging from $77,490 to $101,290 including $1,295 destination. And while we also learned that all-wheel drive will be a $3,000 option, what's surprising is that the optional 3.0-liter inline-six diesel engine will cost $0, this according to official pricing info released by Cadillac. The diesel is one of two engine choices for the new 2021 Escalade, the other being a 6.2-liter V8. The engine also is coming to the 2021 Chevrolet and GMC full-size SUVs, but it's not yet known what the upcharge will be there, if any. Already, the 3.0-liter I6 diesel is offered in the Chevy Silverado and GMC Sierra 1500 pickups, where it is currently a $2,500 option over the 6.2-liter V8. The Duramax inline-six turbodiesel is an aluminum-block design with dual overhead camshafts and a single, variable-geometry turbocharger. Cadillac quotes preliminary outputs of 277 horsepower and 460 lb-ft of torque. The 6.2-liter V8, meanwhile, musters 420 horses and the same torque output. The primary draw for the diesel is expected to be fuel economy. EPA estimates for the diesel engine in the Escalade (and in the GMC and Chevrolet full-size utes) have not yet been released. But in the pickup trucks, the engine returns 23 city/33 highway miles per gallon with rear-wheel drive and 23/29 mpg with four-wheel drive. The 2021 Cadillac Escalade had been scheduled to reach dealerships this summer, but it's not known whether that date might slip due to the current shutdown at GM's assembly plants. Related Video:
