    A good question concerning usage would be where was the oil going.
    I've had a number of vehicles that had lots of miles, circa 100K +, that used no oil or very little.
    I would have thought that today's engines were much tighter until I read the link cooter put up concerning piston slap. Thanks Cooter.
    Going back to an 86 Parisienne with Olds 307, about 85K, I was experiencing a little more than 1/2 quart low at change time. I switched to Mobil 1 and ran it according to how the oil looked. Oil still looking very good I extended the drain out to 10K, more than double previous changes with regular oil. It used no oil what-so-ever in that time.
    I did run Rislone through it before switching to synthetic and oil got really nasty indicating the engine had junk in it.
    Combining that experience with other engines and oil brands I have come to the conclusion that with at least older oils there was a significant variance in volatility. That is the engine did not use it or leak it. It just evaporated slowly at high temps, or in the case of old Quaker it stayed in the upper end mostly. Even with the cooler engines back then, it looked like that stuff you see in the Ford change you oil commercial. And with the high heat at the crossover in V8 intake manifolds it turned into something resembling lava rock.
    If not for that commercial, I would have thought such issues no longer existed because of greatly increase API standards. (American Petroleum Institute)

    Thought I would check in here with an update on my '09 Allure (Canadian Lacrosse). Just turned 7000 miles and the car is better than ever. Having passed break-in, the engine seems to have loosened up and the car pleases me with it's grunt off the line and peppiness in everyday driving. The heated leather seats remain very comfy and the automatic climate control is great in the cold weather we now have. Ride is still smooth and quiet with no rattles. No issues at all. Just a great car.

    Hi i am having problems with my rear shocks loosing its hood. Car has a bad rattle on the right rear that rattles really loud. Car is too stiff to rock it side to side and just about impossible to look under it unless you have a lift. I took it to the dealer 2 times for the rattle and on the second time they replaced the rear shocks. On the way home from dealer the rear end was rattling just as much as ever. I could not contact the dealer because i was just too mad and i would have said things they would not like. After i calmed down 3 days later i called the dealer and told them the loud rattle was still there and that the plastic ( believe it or not ) shock absorber hoods had fallen down again. The Dealer could not believe it and he said the hoods were pressed on. Personally I don't think that they are pressed on . looks to me that they are glued on with some kind of epoxy. Hard to believe they can press metal unto a plastic cover.

    I was wondering if anyone has had this problem. I have seen 2 2010 lacrosse's on the streets and i looked over the rear tires and you can see the cover had fallen from the holder so i don't think i'm the only one with this problem.

    I'm a mechanic myself but i work on Machinery's and i do not have a lift to fix the problem myself by drilling holes on bracket and inserting screws to hold hood in place.

    has anyone else had this problem?

  • I believe there is a TSB for this problem. I would take the car to the dealer and have them take a look. Check too.
  • e_net_ridere_net_rider Posts: 1,380
    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

    White? Mine are black as are hemar's. He did not say which model or suspension. Mine is the Touring, CSX.
  • crankeeecrankeee Posts: 298
    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.

    I thought i put down the model but here is mine

    2010 Buick lacrosse CSX . Its fully loaded with everything offered.

    Luxury Package
    Touring Package w/ 19inch rims
    supreme sound and navigation
    zenons and heads up
    and the cheap Goodyear tires (any Goodyear tire is worthless to me) I will change them this summer

    please note that those pictures are 3 days after the dealer replaced the complete shocks, they say.

    Car has only 8 thousand miles on it
  • 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
  • e_net_ridere_net_rider Posts: 1,380
    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.
  • hemarrhemarr Posts: 4
    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

    here is a link for rear noise at the Buick forums

    Hemarr: Thanks for the link. My dealer is normally great- maybe they have not caught up yet! I'll get back to them.
    thanks again

    I hope this is not a redundant post. The consensus of car magazines and websites is that 4 cylinders just won't cut it in moving a car as heavy as the LaCrosse. Makes sense to me - but I wonder if any readers here have practical experience to report. Perhaps 4 cyl is enough for some folks - ?
  • e_net_ridere_net_rider Posts: 1,380
    I have not personally driven one with 4 cylinder but I had 09 Malibu LT2 with one.
    First, let me say there seems to be a trending toward more power being available, however that may stop or slow with gas prices again getting quite high.
    Many seemed to be OK with Malibu I4 power, even with AT4, but there is a tremendous difference in acceleration when comparing the same vehicle when one has 4 speed and other 6 speed. Mine had 6 speed. Fully loaded, the Malibu would often shift threading my way up the mountains to Nashville from coastal Georgia, but it had plenty of power to make the climb automatically applying proper gearing. Supposedly that Ecotec has endurance that should not be effected, you just have to be willing to adjust to frequent shifting. Certainly much different from running that route with a 73 Town Car & big block 429(?) which got about a maximum of 16MPG. Definitely fit the Detroit barge definition.
    Putting that I-4 into the Lacrosse might be questionable. First the stats that GM has published seem questionable. On the Malibu, the base model is 11# heavier than the LT2? LT2 =3421# curb weight.
    According to the latest Buick webpage, the CX =3829#. With it being just over 400# heavier and the final drive being different I'd bet, the acceleration would seemingly be similar.
    Note: the curb weight for the CXS is now being listed as 4045#. I thought I saw figures that showed it around 4400# ? And that same Buick chart now shows the spoiler as being standard on the CX?

    thanks for the detailed information.
  • FYI: My owner's manual made wiper replacement look easy. Just pull the wiper arm assembly away from the windshield, detach the old blade, put on the new one. However, it is not possible to do that on my LaCrosse because the hood rim blocks the arm. With the hood open, not much better. Using the wiper control and/or the ignition switch, I was not able to stop the wiper with the arm in the "up" position. Solution: I located the fuse for the wipers under the hood. Turned the wipers on, pulled the fuse when the wipers were "up" and they came to a dead stop. NOW I can follow the owner's manual instructions. If the fuse trick didn't work, I was going to disconnect the ground to the battery when the wipers were on but then I would have to reset stuff (clock, radio, whatever). Anyone have a better approach, please share.

    Funny you bring this up. Just last week I was in the driveway playing with the wipers for this very purpose. If the engine is not running and you turn the ignition on, start the wipers, then turn off the ignition to get them to stop partway along the windshield, they won't do it and park automatically. But if the engine IS running when the wipers are on and you shut the ignition off, they stop where ever they happen to be on the windshield.

    Mine is a '09 model.

    Have your tried removing the entire arm?
  • Yep, your solution works on my '05 also. You have made wiper replacement for me easier the next time. Thanks!
  • crankeeecrankeee Posts: 298
    kleaver: Old news. My dealer did know that the shock cover had dropped and re epoxyed the one side. They were not willing to pin them up since that violates the original design. Seems like a glue problem since they have been using plastic shock covers for years. We feel lucky to have a great car and a great dealer to service the inevitable needs.
    We were lucky to avoid the needless accessories that disract the driver, like the nav screens/internet access and endless creature comforts that are prone to need service.
