I feel for you. Huge disappointment in buying a new vehicle. Especially since you are obviously very excited to get it, because you chose it over the competition, and paid all that money for it! I was in your exact situation. If I had to do it again, I would have returned the vehicle and started a legal proceeding to get my money back after they wouldn't deliver me an acceptable vehicle - no more than 2 weeks. Then go buy a new Expedition or Navigator. Or Toyota, Lexus or Infinity. GM has a lot of work to do to fix their: vehicles, manufacturing process, parts suppliers, and dealers. What a mess. The whole "Chevy Shake" in their pickup line is a disaster. If your dealer isn't taking you seriously, phone GM corporate direct and tell them you want an 'Executive Escalation'. You get to people who will work on your behalf to get it fixed right. If you have Desert Duellers, they need to be Road Force Balanced to under 10 lbs. The Duellers are defective but GM probably contracted for millions of them. It takes forever and dealers/mechanics don't like wasting the time searching through 20 tires to find 4 acceptable ones, but that is what it took on mine. (took the dealer the better part of a week to do it as each tire takes about 60-90 mins to tell if it's good or not!). Turning off magnetic ride seems like you're willing to accept that one of the Tahoe's most advanced systems (and costly) doesn't work. I wouldn't accept airing down the Duellers - it reduces the load you can carry. I bought my Yukon because of it's towing capacity - I'm not willing to compromise on that. Otherwise I would have bought a unibody 7 passenger SUV with more interior cargo space. If you're going to keep the vehicle and the vibration is focused on the wheels I would recommend these 3 options: - Get them to RFB below 10 (20 tires to get 4) - Tell the dealer to take a set of 20''s off a truck on the lot and drive it around and see if the vibration goes away. Then you can decide if you want to pursue getting your $3200 back for the 22" upgrade and sticking with the 20"s. - Argue for them to put Michellins on your 22" - maybe there's some compromise they're willing to do I wish you the best of luck.

Update - its been a year since i drove the truck off the lot and couldn't drive it over 100km/h. Spent months and a dozen visits to the dealer and tire shops. Complained to the dealer and GM Executive review. I was so frustrated with this whole issue that I just drove the truck. In August, I had the person at GM Executive Review reach out and ask me if I was happy now, and I replied back that I was so frustrated and I wasted a ton of time trying to fix something that should have been right from the factory. She put me in touch with another dealer in Toronto, who specializes in fixing these issues. The short version is that the dealer had my truck for a week and I got it back and it rode smooth! Longer version: They replaced 3 tires and road force balanced them to around 10lbs or less. The desert duelers are terrible/defective. The dealer orders 20 tires and has to road force balance them to get them around 10lbs. They send back 17 bad tires. One person confided that he just bought Michelins and solved the problem on his Silverado. But the GM engineers don't sign off on the Michelins on that truck and therefore it's not covered under warranty. The dealer is forced to dig through 20 tires to find 3 good ones. They ran the truck with the pico meter before and after, and it was much better. I've driven it for about 3 weeks and the truck rides much better. I just swapped the 22' factory rims with the duelers for my snow tires (20' with Blizzaks), and I really noticed how heavy the 22's are compared to the 20's. The weight difference is pretty significant, and I can imagine the shocks and springs work overtime on the 22's and that probably contributes to the reduction in ride quality when the 22's are on. In sum, the wheel balancing on the 22's is solved for me, and it took someone who acknowledged the issue, and knew how to fix it. I still will never buy another new GM vehicle given my experience. But I am grateful to Holly, the GM Executive specialist, and Bob, the service manager at Roy Foss in Thornhill, who tackled the issue and fixed it.

I left it with them and they put me in a rental Yukon - it rode like a dream. Just like mine with the 20" wheels I bought. They put on a 4th set of 22" hard chrome wheels. It's better, but still vibrates on the highway. Sigh. This is ridiculous....

First post on this site - I would never buy another GM vehicle. The quality control of their product is terrible. Their dealer network is in the dark ages. Complaints to corporate are acknowledged, but nothing happens. I’ve purchased cars from Toyota, Honda, Dodge, BMW, Mercedes, and Lexus. And never before have I been treated as if no one cares. The manufacturer delivered a 2016 Yukon Denali XL to the dealer in Toronto and it had 4 bent 22" Chrome Wheels (a $3200 upgrade). 120 Days ago I drove it off the lot and had to immediately return it because it shook so bad at 100kms/hr that it felt like the wheels were going to fall off. As unbelievable as that sounds, it gets more unbelievable. It took 2 weeks for the dealer to tell me it was going to be 90 days to get a replacement set of wheels. 90 days! Instead of driving around on bent wheels, or in a 2 year old beat up rental car the dealer had arranged, I bought 4 brand new 20” GMC factory take-off wheels with winter tires, and the Yukon drives perfect. However it should be noted that neither GM or the dealer offered to give me a discount on anything. I had to solve their problem by shelling out another $3000. I’ve logged complaints with the corporate ‘Executive Review’ and it wasn’t until I threatened to write Mary Barra a letter, that wheels showed up 60 days after purchase. They were installed on the Yukon and I was assured that they were balanced and they were not. I returned the wheels and an embarrassed service manager left me a voice mail and said 1 wheel and 3 tires were defective! Two weeks later, after no followup, I called the dealership and discovered the service manager left! And left my wheels and case sitting there with no followup. The new service manager said they would get 4 more wheels and tires. They were installed. And while the Road Force Balance readout at the tire shop say they are within specs, the truck still shakes and vibrates. I have never wasted more time on a new truck. Every trip to the dealership is a half a day out of my busy schedule. I was going on vacation for 10 days, and I called the service manager and told him he could have the Yukon for 10 days and solve the problem. He said “Why bother? We’ve put 3 sets of wheels on it, and you’re not happy. Let’s just do a factory buy-back”. Two days later, while I am on vacation, he informs me the Warranty Manager says it doesn’t qualify and the shaking and vibrating “may be as good as it gets”. GMC’s +$90,000 flagship SUV that was delivered with 4 defective wheels, and fitted with 2 more sets of defective wheels, is expected to ride worse that a 20 year old used car? This entire experience has been a nightmare. This company is in the dark ages when it comes to the customer experience. I’m confident that every other manufacturer I’ve dealt with would have been so embarrassed with the delivery of a defective vehicle (how does it pass quality control with 4 bent wheels in the first place?), they would have been proactive and worked to address this concern. This dealer is a Corvette dealer and doesn’t even have a road force balancing machine to balance these tires - they have to be sent out to a tire shop. My 20" wheels with Blizzaks ride great, but when I put the 22" on (that are RFB's below tolerances), it vibrates and shakes at highway speeds. AWJ52 - your posts at least give me some hope. I will try airing down the 22's, and writing a letter to Mary Barra. This is unbelievable on a $9000 vehicle, let alone a $90000 one.
