Re: Quadra Lift ride Quality

My ride is a 2016 4x4 Summit 5.7L. At any rate, I have read this thread and all comments from start to finish, and I think that things ought to be put in perspective...

The JGC with QL is a unibody-based truck frame (with a more stiff rear axle) rather than a gussied-up crossover vehicle that's nothing more than a suburban shuttle, based on a car frame. Therefore, don't compare apples and oranges.

Weighing in at more than 5000 pounds and being rather top-heavy as a consequence of being a true SUV, do not expect an ultra smooth Cadillac-like ride, nor sport-car handling. That said, I am quite pleased and impressed with the overall handling and ride quality of the Summit and its QL air suspension. In fact, the Summit is far smoother and more comfortable than the likes of a 2015 Infiniti Q50 sport sedan, which rattled my back teeth, especially on highways.

But all the comments have been based on GC with vs with out.

But I'm with you, the QL rides just fine. And so does non QL for that matter.

Preach on "Psydoc"!! I am completely satisfied with my 2015 4X4 Summit 5.7L as well. It exceeds my expectations for a vehicle with its capabilities. We will just lovers "Love" and haters "Hate"!!

Re: Quadra Lift ride Quality

My QL is pretty good until I get cracks at highway speed then I swear all four wheels come off the ground. There is one route on my way to work that requires me to constantly adjust steering input because the QL is treating me like a 64 impala low rider with switches. When I drive the same route in my wife's Ford Edge AWD its a thousand times smoother ride. Even my EVO with Ohlins racing suspension is more tolerable.

I always run 40 plus psi tire pressure after all its 2016. Most of the time I prefer to keep pressures at the upper limit. Anything under 40 and the thing is a plowing pig.

I know that one's take on ride/handling is subjective but I can't even begin to comprehend a ride description like that on any WK2 with the QL suspension.

Tire pressure can make quite a difference in ride quality if you're running 20's on your GC. Have you played around with pressures to find your sweet spot? My 14 rode and handled fine at the recommended 36 psi cold. Harshness increased above that. I still run 36 cold on my 16 HA even though (for whatever reason) they recommend 33 front / 36 rear now.

33 front / 36 rear wonder when/why they changed that is that through out all the 20s now on the my16+

It is on the HA, can't speak for other models. I was a little surprised to see that on the door frame decal. I have all four set to 36 psi and it rides and handles fine.

yeah strange I have often seen front tires requiring more which I always attributed to a heavy engine sitting on them but never saw the opposite. maybe to improve ride quality when they changed tires from the super soft forteras?

It could be the new Ecopia's or maybe for the slight suspension difference the HA has. Maybe someone with a 16 (other than a HA) with 20's can check their door decal and report what it says? It would be interesting to see if those tire pressures change with engine size as well.

Quadra Lift ride Quality

I find the ride to be average with QL. I had a 2012 Overland without QL and it seemed to ride nice but I don't really remember.

Squat upon takeoff is bad. One thing I really hate about QL.

The SUV excessively wobbles side to side when turning if the pavement is uneven.

The ride is sometimes jittery at speeds like 25-55mph with QL. Meaning a lot of small bumps and vibrations are felt from cracks and broken pavement. It also translates to a buffeting feeling in the cabin, like plugging up your ears.

I've had a 2014 Overland with QL and 52k miles and now my 2015 Overland with QL with 23k miles. Same complaints on both but neither systems have ever given me any issues.

I think they should make the QL adaptive. An adaptive QL system for the Summit would make total sense since it's the mall queen. It would clean up some of the QLs sloppy characteristics, on road. Since every new SUV coming out offers an adaptive suspension, I guarantee it'll be on the redesign GC that we will see soon.

Re: Quadra Lift ride Quality

I've never experienced any of that.

Anyone who feels the ride / handling characteristics of QL are poor or average has never owned any of the previous generations of the GC.
