Sorry that you feel that way. You haven’t actually provided much in the way of specifics, (including those words), making it pretty tough to understand the problem

I don’t have my car yet so can’t check myself but doesn’t the suspension adjustment screen provide the ability to individually adjust compression and rebound damping?

It does, but it doesn’t do any good. In fact, you can’t tell the difference between the softest and hardest settings. The sliders move, and the graphics change on the dampening screen, but the feel in your butt remains the exact same. At all ride heights. It’s subjective, of course, but I took the tech and SA with me and both said they can feel the difference, but it is almost imperceptbable. So yeah, it’s “within spec”, but the ride sucks.
Completely agree with you. When I had a P90D as a loaner the suspension was much better. Really is the biggest downer of the refresh and does not make it an enjoyable car to drive. Second biggest downer is the media interface and lack of configuration on drivers console. Don’t get how you have a driver console that has no adjustability. For a tech company complete let down, but know we get stupid games as updates.
Coming from a M3P, I was looking for a more comfortable ride like my wife’s Raven has. I was disappointed how bouncy the plaid was but noticed that the ride got much better with 4 people in the car. I tried adding weight to the trunk and that made a big difference. (four50 pound bags of pool salt) Now I can feel the difference when changing suspension modes. Talking to a plaid suspension specialist at the delivery event, he mentioned that they increased the spring rate.
For those with the bouncing issue, is the effect in Comfort mode and essentially described as a lack of damping, where car rebounds multiple times over bumps?
I’ve directly compared 2018 100D with my 2021+, and the latter is actually much smoother over bumps at 50 mph. The 2021+ bounces far less and hunkers down after hitting the same bumps. Anyway, I cannot compare to Raven, but I think the ride is better than ever in my 3rd Tesla.

i only have the issue on speed bumps and I drive in Comfort mode. Especially in the rear, the car goes up and comes down hard even if I am going 1 MPH. It is almost laughable.
Thank you. I increased the pressure to ~40 from the as-delivered pressure (which was 36) and I felt an improvement, but not a significant improvement. Problem persists. Appreciate the many thoughts on this thread, however.
Thank you DBV1. Yes, exactly. And I am comparing it to a BMW 5 Series, so your comparison is apt. Following this thread and hopefully there will be a fix at some point.
Chill mode also helped, I agree. Still not enough of an improvement, but it helped with the overall feel, overall comfort for my passengers and me.

In my '22 MS I can definitely tell the difference between comfort and sport mode in suspension setting. Came from LX570 if that matters. Aside from clunky noise when slow turning, car is perfect (hopefully service will take care of it)
I wonder if the stiff suspension is leading to all the creaks and rattles as time goes on? My car was dead quiet up to 1000 miles, but after that it's already a rattle box.
I've modified many suspension components on other cars and over time those cars started to produce rattles that were not present before the upgrades.

As an additional data point, when comparing my 22 Plaid to my 16.5 P90D MS, the suspension is so much better on the newer car. I have not had any of the bouncing reported in this thread. I use auto around town and comfort on AP activation. I have 19 inch wheels which undoubtedly helps with the ride.
I'm not sure that the different settings under "advanced" makes any appreciable difference either. I think comfort does allow more bounce when hitting big dips on the highway which isn't really a good thing. At low to medium speeds on local roads I see no difference at different settings. I do see the dampening number change when selecting different settings but don't feel any setting that takes away the initial harshness and crashing of hitting even modest bumps in the road.
If what someone said above is true, and they increased the spring rate, that sounds like it may not be fixable with software? The car is just too highly sprung for daily driving in order to accommodate the track?
Mine feels fine and I have everything manually set as stiff as I can but I would like it way tighter still. Track mode is even better but that forces you to trade off certain street driving features. I came from a modified GTR and with that I set the suspension to race mode all the time on the street. I like to feel the road, even the ruts. I think this could be chocked up to perception. We all have different expectations. Had a Lexus LS460 and that thing was so floaty I could not stand it but plenty people liked it. Being an engineer it is impossible to make a car right for everyone. In our industry we had a saying. ”Customer wants large buttons but on a small device“ impossible.
I’m 99% sure the car rides much better on Medium Height than on Low. I need to triple check it’s not placebo effect. Maybe I’ll have to have my wife set it blind or something.
I have it on Advanced max Comfort and height set to medium.
I’m on 19” Summer OEM tires set at 42psi
I have definitely felt the bounciness. And other times think it’s riding great. I believe it correlates with height more than comfort setting.
I wanted to keep it on low to minimize chance of developing vibration. But it feels better on Medium.
Curious if others have tried this.

I also run 38 PSI. Makes for a better compromise between ride and efficiency IMHO…

Has anyone heard anything new from Tesla about this issue? I too find no difference between the suspension settings and even when set to the softest, the ride is not comfortable. I will try the lower tire PSI as suggested, but we have paid for a comfort mode that has yet to be felt.
