Suspension Wiggle Jiggle (5 Viewers)

[maasthor]

Hi, this is my first post; 2026 Luxury plus. after about 3,000 miles, 3 months...i cannot for the life of me believe a luxury vehicle, or any vehicle for that matter, even a truck, could be this jiggly, wobbly, rough of a ride. I owned an F-150, it was smooth compared to this. I have tried "comfort" and all the settings. Even just expansion joints cause reverberations throughout the vehicle. on some roads you can hardly have a conversation for being jiggled around so much. I know, the 22" wheels... but that should not cause this much wiggle jiggle. I find myself apologizing to passengers. Is this for real, or could there be something wrong? Again, I know it's a truck, but this is ridiculous.

It's a common owner complaint. What you can do is swap whees/tires to get more rubber, run a lower PSI. And/or replace suspensions.

I recommend sticking closely to the 33psi cold inflation pressure, as that made a big difference for me. You might also consider tires with a softer sidewall, as the factory tires seem to have very stiff, sporty sidewalls.

I found that after 10k miles, the ride in my car seems considerably softer and much closer to the experience I'd expect from a fat boat like the GX. Good luck.

thank you for the replies. I actually like the 22" wheels but may get different tires (AT Dueler Ascent are appealing), still, the full-vehicle jiggle seems more about the overall suspension than wheels/tires. I had Acura, Audi and know what tight/harsh rides are like with little rubber and tight suspensions. I own a Jeep wrangler and I swear the jeep is a smoother ride. I experienced a "death wobble" in that and fixed with new shocks. This GX reminds me of what the Jeep was doing just before full death wobble.

My first drive after delivery shocked me due to exactly what you’re describing. I checked the tire pressure to find the tires were at 44 PSI. I took them down to 33psi and that helped greatly. Since then I have still been sensitive to the ride to the point I had the service manager drive it with me. He said it felt like all the other GX’s. After 5,000 miles I can say the ride is much better so either we have gotten used to it or the suspension has “settled in”. I hope you have a similar experience.

would also expect more tire sidewall would make a difference. I've got a nice ride with my Toyo AT3s 275/70/18 EV SL on my OT. I had a 94 Jeep with that horrific Death Wobble a few times and unless you've experienced it, no way for someone to appreciate how that feels at >50 mph, like either or both the front tires flying off or steering components coming apart.

I agree with @280driver, regarding the ride softening up and tire pressure. To add…make sure to monitor the tire pressures and make adjustments when cold. Not after driving.



I’m changing mine fairly regularly and I adjust them to plan for the outdoor forecast. When it’s warmer out, I use 33 PSI and when it’s colder, 35PSI. Geographical location also comes into play but after owning and driving a big RV, I realized the true importance. Also, I’m still running my stock P+ 20” wheels at about 6,500 miles.



My wife has been a jeep wrangler owner since I met her. Though I’ve never experienced the death wobble myself, she has a few times. It doesn’t sound enjoyable.
