2018 Denali XL with ride issues

[Gezim Veliu]

I have a 2018 Denali XL, it has about 30K miles and seems like the ride is getting worse and worse, dealership says its fine, this is a vehicle I use for work ( Private Black Car Service ) its not beaten daily and its well kept, yet somehow its getting to me that my 2016 Denali XL has a better and smoother ride.

ANY ADVICE???

MRC front suspension?

there is a TSB for them that could help

did mechanic drive it alone? you should go with, if so.

Some days it feels great and other feels like crap.
