I believe there is a TSB for this problem. I would take the car to the dealer and have them take a look. Check buickforums.com too.

TY for the notice. I just checked mine. They have not yet fallen but both sides have the outer half out of the holder. Another on my punch list.
TY GM, you could have put a known good load-leveling system on for what this will cost you.

Great post and the pix highlite the problem.
We have ~8000 miles on 2010 CXL and the white plastic shock hoods are down on ours. You can see the reddish epoxy on the hoods when the hoods are seated correctly in the upper cast metal shock bracket.
If their is, in fact a TSB out per the other poster, then GM thinks they know how to fix the mating of the plastic hood to the metal shock bracket. The hood is supposed to keep water,salt,etc. out of the shock piston and seals to protect the integrity of the piston- very important so this is an excellent catch and well documented post on a potential problem down the road.
THANK YOU! Crankee

2010 CXL with H-arm and FWD per prior posts. The boots or hoods on ours are white plastic with rust colored epoxy smeared all around. The plastic cover over the shock body is black on ours. Our hoods are both down 1/4" or more from the metal upper shock bracket and you can see the piston rod.
I called the dealer this AM and the initial reaction was they had not heard this complain and no TSB so far. They are checking for TSB/fix/parts and I will take it in then. I know that the shock piston needs to be protected from weather,salt etc so the plastic hood cover would have to be secured into the metal shock bracket with the epoxy. I will follow up if I learn more with this but the post on this site with the pix is pretty self explanatory.

Mine is also a CXS with touring package and the hoods are black plastic.
to the other user that stated to take car to dealer, please read my post again and you will see i stated the dealer just replaced the rear shocks because the hoods were down on the original ones, so it will be going to dealer for a third time for same thing. Web have a lemon law in NJ and it states that if you have to take your car to dealer more than 3 times for same problem its classified as a lemon.
I will be making an appointment again for next week. I'll post the results

Sounds like we have similar but mine is 2011 so it was not fixed with a production update.
I like the touring package except the GY. It seems to me they could have implemented it better for when not in sport mode.
The xenons and HUD are great as well as the blind spot stuff. I feel they could have done better with the rear camera. Its range of clarity lacks. If you get exhaust condensation, clouds, it is near useless. Some angles of sunlight are bad. And if backing up where you need to ride brake, the red light destroys clarity.
The sound and NAV, well it is lacking in my opinion as well. First it could use a lot more voice commands. The NAV map is old and seems to have quite a few bad mappings and even stupid voice commands. (turn left when you actually need to turn right) The XM has way too many dropouts on this vehicle compared to 09Malibu. And the HK system seems to have terrible fidelity. Both on low end and high end. I pushed the treble to max to try to get faithful reproduction of cymbals, bells, other very high harmonic instrumets and it just does not seem to be there. (I will have to retry the highs with a pressed CD) Part of it may be XM compression methods.
There is a lot to like about this car compared to some lesser models but it does not seem to have the quality polish it should have.

Hemarr: What ever became of your latest trip for the hoods on your rear shocks? I do have white plastic hoods on 2010 CXL with H-arm suspension and FWD only. Hoods have dropped down partially from metal upper bracket, so I assume they will eventually fall into the black plastic shock cover as in your picture. My dealer seems completely unaware of any general problem with the epoxy/glue holding the hoods in place. I have not taken it in yet but they are a very professional dealer so no worry here.
Please let us know if there is a TSB, known problem or more info on hoods.

My dealer has replaced the shocks and 2 days later the hoods had come down again.
Its going back in tomorrow for new shocks again and for sway bar bushings along with spring retainers as they are the source of my rattling sound.
Why your dealer does not know of the shock problem is weird to me because its happening with all Buick models of lacrosse's 2010 and 2011. I even noted the hoods falling from shock at the dealer and on 2 cars i have seen parked and i looked above rear wheels.
The dealer says the upper shock bracket is pressed onto the hoods but it looks to me that its epoxied up instead. I'm a mechanic and I'm sure i could retain the hoods in place with a u bolt but don't want to do anything while car is under warranty
