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.

Why Cadillac needs a real truck in its lineup

Premium brands such as BMW, Mercedes-Benz, Lexus, and Cadillac sell vehicles that cover the spectrum from car to crossover to SUV. But trucks? They remain the last frontier when it comes to luxury brands. These days Chevy, GMC, Ford, and Ram sell cheap, bare-bones work trucks alongside loaded models that top $75,000. There is a reverse elitism that comes with this sales tactic. A brand gets to reflect a rugged working class lifestyle with the emblem up front, while what's behind it costs as much as a small house in middle America. But Americans who spend big money on cars and SUVs have always gradually tailed towards luxury nameplates over time. Everyone knows what an Escalade is, and thanks in large part to that image the Escalade is now the best-selling fullsize luxury SUV in the USA. Cadillac's flagship model, along with its midsize luxury crossover, the SRX, routinely outsell the competition from Audi, Mercedes, and BMW, not to mention Ford's Lincoln brand and most of the Japanese rivals. With trucks already dominating overall sales and headed into the pricing stratosphere, I believe it's time for Cadillac to consider a fullsize truck. And no, not a lipstick version that merely takes a Chevrolet Silverado pickup and throws in a few leather seats and some slight interior touches. That experiment already failed both for Cadillac (the Escalade EXT) and for Ford's Lincoln brand (Blackwood, Mark LT). Cadillac is an American brand that currently focuses a ridiculous amount of energy and resources trying to compete with European car offerings. The brand needs to create the Cadillac of trucks. Head honcho Johan de Nysschen has been blunt in his desire to "restore Cadillac to the pinnacle of global premium brands, not in sales but in aspirational brand character." This sounds well and wonderful. But the present problem in achieving this goal is that, on a global basis, Cadillac is a failed brand. Look at Europe, where Cadillac has sold so poorly in recent years that former Soviet manufacturer Lada managed more new registrations in 2014 by a factor of more than four to one. Cadillac is an American brand that currently focuses a ridiculous amount of energy and resources trying to compete with European car offerings. After more than 20 years of Cadillac models selling themselves as import killers, the only one with sustained success has been the CTS, and even that has been a marketplace loser for the last several years. The CTS-V?

Cadillac's Blackwing V8 was the best engine at the worst time

It should be clear that GM knows how to innovate and engineer excellent products when it wants to. Cadillac's 4.2-liter twin-turbo Blackwing V8 is recent proof of that. Yet, as related in an extensive Road & Track piece, the Blackwing became victim to some of The General's bugbears, like the reticence to — for whatever reasons — unleash its excellence everywhere, fund that excellence, and be consistent with that excellence over the long term beyond the Corvette and full-sized pickups and SUVs. The R/T story relates tales told by "several people deeply involved with the Blackwing project" about how an engine 18 years in the making was deprived of its reasons for being in less than three. Starting around 2000, GM spent a dozen years building Cadillac up to the point where the American luxury brand could rationally flip to the chapter called, "Taking the Fight to the Germans, but for Real this Time." The first steps in the plan meant an exclusive platform and an exclusive engine. The platform was called Omega. You know the engine's name. They were going to be the aluminum-blocked fist and velvet glove enabling Cadillac to break on through to the other side of luxury — proper luxury to global standards, that is — with a range of beautiful and dynamic crossovers and sedans. An engineer involved in the project estimates GM poured $16 million into the Blackwing's clean-sheet development. Many more seven-figure sums went into creating the first sedan on the Omega platform, the CT6. The automaker dropped millions again poaching ex-Audi and Infiniti chief Johan de Nysschen, and moving Cadillac's headquarters to New York City in 2014. Further pallets of cash funded the development and debut of the Escala concept at Pebble Beach in 2016. In 2018, GM revealed its dramatically named DOHC twin-turbo V8. Considering what came before, the Blackwing clearly wasn't designed for cars. It was designed for world domination. However, against the backdrop of plummeting sedan sales, the CT6 didn't sell like GM had hoped. The automaker hesitated to marshal another fleet of Brinks trucks to fund entries into a cratering bodystyle. Removing sedans from the world domination equation created more difficult math for the crossovers and the Escala.
