#1 of 16 Two problems I am having with my CXS by nugba Nov 07, 2006 (12:45 pm)
Hi all...   I love my CXS but I am having two problems that my local dealership cant figure out.   1. My car sometimes runs the battery down overnight while sitting more then 8 hours.   Dealership upgraded software but it still does it once a week or so. Battery is taking change and alternator is working fine.   2. Car gives a vibration noise in the rear while in drive at a light.   They keep messing around with exhaust thinking that it is touching something but after having it in twice the noise is still there loud as ever!   Anyone have these problems??   John Replies to this message: KarenS (Nov 07, 2006 4:53 pm) rake2 (Nov 10, 2006 1:15 pm) gmccoy (May 28, 2007 4:19 am) dandydon2 (May 28, 2007 10:07 am) gmccoy (May 28, 2007 2:59 pm) estamper (Dec 15, 2007 10:06 pm) imidazol97 (Jan 30, 2008 8:44 am) imidazol97 (Jan 30, 2008 8:41 am) imidazol97 (Jan 30, 2008 8:23 am) imidazol97 (Jan 30, 2008 8:23 am) waylanddon (Apr 05, 2009 3:42 am)

Replying to: nugba (Nov 07, 2006 12:45 pm) I have not had either of those problems. Of the two, however, I'd be far more concerned about the first. If you have it in another time and the problem remains, check your state's lemon laws, because I would think that an electrical system that drains the battery at least once a week clearly affect the use, value, or safety of the car, which, at least in Pennsylvania, is the main criteria to look at to see if it falls under the lemon law.

I had that rundown problem with my 2000 LeSabre, checked everything we could think of with no change. It never happened again after I had to replace the battery.

Replying to: nugba (Nov 07, 2006 12:45 pm) I am also having the battery rundown problem on my 2007 Lucerne CXL. It has been to the dealer 3 times so far and this time they have had it for two weeks and still no resolution. What has your dealer found out so far about the problem?   Thanks!   Gary Replies to this message: dandydon2 (May 28, 2007 10:07 am) gmccoy (May 28, 2007 2:59 pm)

Replying to: gmccoy (May 28, 2007 4:19 am) Hi Gary,   Don't know if this will help, but I found that the battery ran down overnight for no apparent reason in a 2001 Chrysler 300 I used to have. Battery checked out OK. Discovered that the problem was due to my inadvertently turning on the instrument panel light switch when I wiped the dashboard. It seems that when the switch is turned full clockwise, the lights stay on indefinetly.   Dandydon Replies to this message: gmccoy (May 28, 2007 2:59 pm)

Replying to: dandydon2 (May 28, 2007 10:07 am) I am sure that is not the case here, because the car has a battery saver which will automatically turn off the interior lights if they are left on. I did find a TSB 06-06-03-009 which deals with battery run-down when the car is turned off, but don't yet know if it is my problem. It affects the Lucerne, Tahoe, Suburban, Impala, Silverado, and presumably a number of others. Apparently, the Body Control Module needs to be re-programmed with new software. We'll see if that helps once I talk to the dealer about it tomorrow.   Thanks! Gary
#8 of 16 Fix for the problem by nugba May 29, 2007 (5:54 am)
After months and trying almost everything else my dealership found the problem. It was the OnStar Module staying on trying to get a location fix. They replaced the OnStar Module and after 4 months of driving never had the problem again. Before the fix I was jumping the car every 3 weeks...

Replying to: nugba (Nov 07, 2006 12:45 pm) The noise you are experiencing sounds like the one I had. It drove me crazy! It sounded like a vibration on or around the rear window shelf area. I finally found the problem by crawling into the trunk with a flashlight and closing the trunk. Not to worry -- there is an emergency trunk release inside the trunk. The problem was caused by the two spring tension rods that run between the trunk hinges. With the trunk closed -- the rods were close enough to vibrated against each other. I took an 8" length of rubber vacuum hose with an inner diameter the same size as the tension rod (purchased from the local car parts store) and sliced it length-wise with a razor blade. Then I slipped it over one of the tension rods at the point where they are riding against each other. Lock the piece of hose in place with two or three nylon tie-straps and that should do it.

#10 of 16 Only two problems by paradox2 Jan 30, 2008 (3:58 am)
Geez, I wish that were the case for my Lucerne. Mine is garbage..... I can list you 20+ things wrong with mine, some of which have been corrected after numerous visits to the dealer, and others that they cannot/will not fix. Wack on the head...I 'shuda' bought a Lexus.
