150-200 kWhr batteries and 800V charging systems (ala Porsche Taycan) are where it will be at for electric trucks that can tow. 200 kWhr batteries would probably give a reasonable range for a pure EV, and 800V charging systems will charge twice as fast as the Tesla 400V superchargers, or let you charge a 200 kWhr battery in the same amount of time as a Tesla 100 kWhr battery @ 400V. What I think would be interesting is a series-hybrid truck with an all-electric drivetrain (think Volt), enough battery capacity to keep things going for quite awhile (maybe at least 100 kWhr), but then a beefy enough ICE to keep things going when you're pushing the limits. That 2.7L turbo-4 might work pretty well for that. A lot of weight and cost and complexity there, but it could work. These first gen EV trucks will just get their foot in the door with whatever they can do, and will probably have pretty limited towing capabilities as far as range, but things will only get better from there on out. I don't think gas and diesel powered trucks will be going anywhere anytime soon. There has to be a robust grid of 400V/800V charging stations or whatever they end up standardizing on everywhere including out in the sticks for these things to take off, and then our entire electric grid will probably collapse long before then. Lol. EV's are cool, but our grid won't handle a critical mass of people all charging their EV's overnight.
Yeah, there's not really a middle ground "just right" suspension in these trucks. The standard premium ride suspension is way too floaty and bouncy for me, and then the Magnetic Ride on LTZ/Premier trucks is definitely on the stiff side. I've observed Suburban LT's with standard suspension definitely having a lot of rear end bounce on the highway over bumps that my Premier with Mag Ride handled just fine. Whether it's that or blown shocks, I dunno. Between the two, it was the Mag Ride or nothing for me, as all of the body motion with the standard suspension would have made half of my motion-sickness prone family members ill. Even I got a little motion sickness with the standard premium ride suspension on a Suburban LT that I test drove. If there's a sweet spot for overall ride and handling quality, I'd say it's the LTZ/Premier trucks with Magnetic Ride and the 20" wheels.
Yes. 2018 Premier with Magnetic Ride and 22" wheels. There's TSB's for the vibration issues if you search the forum, and probably right in this thread. They probably just need to road-force balance the tires, and if they can't be balanced within spec, to replace the tires. Lots of people have done this. I had some minor vibrations/buffeting sounds at 66 mph (and 63 when tires were cold), but just short-circuited the whole thing and went straight to the Michelin tires out of pocket, as there were other reasons I didn't like the factory Bridgestone tires, lack of durability being one of them.
Okay, it's just the tire balance and/or Bridgestone tires issue, but you can lose thousands of dollars trading if you want. Did you not test drive? 2,200 mile road trip from D.C. to Orlando and back over the holidays, zero ride complaints or vibration issues with the Michelin tires and 22" wheels. Swapped out the Bridgestones for Michelin Premier LTX since my post a few above this one.
I decided to pretend that I was an auto journo again, and wrote a nice first look blog on the new Hoe and Burban. Hope you enjoy reading. ? FIRST LOOK AT THE 2021 CHEVY SUBURBAN AND TAHOE FROM A RECENT OWNER
Hi folks! Wrote a 1 year review blog of my 2018 Chevy Suburban. First time truck owner, first time American vehicle owner. "WE" love the Burb, my wife included. Just today it brought home the massive air hockey table from Costco that's on sale for $299 in store, but $469 online due to delivery fees. That sucker is 92x50" and weighed a freaking ton, but I stuffed the whole thing in the Suburban today and just updated the blog. It costs me about $500 extra in fuel bills per year versus the Chevy Traverse that I was almost going to buy, but it's paid for itself many times over in terms of utility and hauling ability, and time and productivity not wasted by being able to haul everything myself. The Suburban has been a truly awesome purchase. Zero regrets. CHEVY SUBURBAN LYFE - ONE YEAR REVIEW
BUMP — really want to get rid of these and clear out my garage. $400 for all 4 tires. They're basically NEW. 3 of them have 10k miles on them, and the other is literally brand new. Happy to drive an hour or so or meet halfway someplace to offload these. If you want a basically new set of tires on a budget before winter and snow, these are it.
Our E70 X5 (2012) was great. The X5 and most BMW SUVs have always been built in Spartanburg, SC since the original E53 X5 (1999), including for export back to Europe. It can also be tough to delineate things that are inherent in the design, and then things that can be traced to actual "build" and/or assembly issues.
Sorry to say that this has been a well known issue of this entire generation of K2xx platform trucks. Buyer beware. I did take mine for a very thorough test drive before buying, including up to full highway speeds, to confirm that my particular truck didn't have the issue, or at least not much of one. Wouldn't have bought the truck if there were serious issues. I did just swap out the OEM Bridgestone tires for a set of Michelin Premier LTX more for durability reasons and not for any ride or vibration reasons, but they do ride more smoothly and helped to get rid of what little highway vibration issues I had before. As posted above, there's some TSBs to fix this. In addition, you can have them road-force balance the tires, which need to be within a certain tolerance also. It's a bummer to hear that 2019 trucks can still have these issues, though! All of the manufacturing fixes they could make were "supposed" to have been implemented by the 2017 model years, so you'd think pretty much all of the 2019's ought to be safe. What a bummer, but good luck getting it all sorted out!
Bump. Have been traveling a lot lately. All 4 tires still available.
Definitely look for the infamous highway buffeting noises, especially 2015-2016 models, double especially on LTZ with 22" wheels and the Mag Ride. It's less of an issue with the 20's. Get it up to a good 70-80 mph. Most of the manufacturing improvements and bandaids to improve it were in by the 2017 models, which got it as good as possible, but not perfect. My 2018 had very mild "buffeting" issues on the highway at two specific speeds, but wasn't a big deal. Swapping out factory Bridgestones for Michelins fixed it. The issue is because of less than perfectly balance tires from the factory putting a lot of vibrations through the body structure at highway speeds, and said body being a bit too thin (to save weight) and ending up vibrating in such a way that it seems like somebody has one window open a crack and a pulsating pressure imbalance. Road force balancing tires can help, or swapping out the factory Bridgestones for Michelins, or going from 22's down to 20's, or having a 2017+ model all helps. Also, if you care about performance at all, get one with the 3.42 gearing. Look for ones with the 2-speed transfer case and a setting for both 4HI and 4LO on the dash. It's almost a sin that the 3.08 gearing is standard. The truck drives a lot better with the 3.42's and there's no fuel mileage penalty either. At cruise on the highway at 70 mph, you have 25% more power available in 6th gear with the 3.42's due to the engine being in a fatter part of the torque curve, which makes a huge difference going up highway grades. Hard to believe that 200 rpm could make such a difference, but it does. The 3.42 trucks are also probably around a half to a full second faster to 60 mph. There's a reason why most every single press fleet truck all had 3.42 gears.
The 8-speed transmission was left half-baked for the K2xx platform trucks, because GM was working on the joint 10-speed project with Ford at the same time. They claim to have improved it a ton in the T1xx trucks. A fluid change might temporarily mask some issues, but I seriously doubt it's going to fundamentally change the nature of the transmission. It is what it is. If it's going to worry you, just look for a Suburban or Yukon XL with the 3.42 gearing with the 5.3L/6-speed combo. It's nearly as good and without any of the issues. The 6L80E is pretty solid.
It's just the trend these days. I didn't actually want the 22's. Funny thing, the Michelin Premier LTX actually costs more for the 20's right now than it does for the 22's. LOL
