Hi all!! I have a 2007 Buick LaCrosse CXL, I bought it last January. Ever since I bought it the tires have been leaking air, I have to put air in them at least twice a week. We have been to 3 dealers to have this problem fixed. I have been told it is the tires changing pressure, But the tires actually lose air, we have to put in at least 10 to 15 lbs each time, on one or more of the four. Does anyone else have this problem?

Hey there,

one of 2 things.

1. valve stem has a crack in it (hose down the rim rub a bit of soap around valve see if it bubbles.
2. corrosion on the rim inners due to moisture seeping in will not seal the tire to the rim. dismount tire electric steel sander on the inner rim remount and done.
Mine was both all fixed. I had the 2005 cxs chrome wheels
