#60 of 97 2011 Buick Lacrosse CXS Electircal by fastnfurious18

Aug 10, 2012 (11:08 am)

I am having a similar problem with my 2011 Buick Lacrosse CXS that was purchased brand new. This problem occurred around 5,000 some odd miles in February of 2012 and it is now August of 2012. My car has been in and out of the dealership over numerous days. (It will be a total of around 48 days now, which is completely ridiculous.) It has died on the highway twice with no electronics/brakes/steering, putting my safety in danger as well as others. The car is also having problems not starting and has been a frequent problem. The dealership has replaced body control modules, frayed wires under the steering column, key less entry modules, and media center modules. GM is clearly trying everything in the book to avoid classifying it as a lemon. Mind you, this car has also had quality assurance issues such as the bumper being misaligned with the vehicle, the back covers of the entertainment system DVD seat covers popping off, plastic of console coming off, and a rattling in the wheel well brake shield covers. This car is brand new and has been having all of this issues! There is no reason for a vehicle to be brought into service that many times! So with that said, I have began to documenting everything very closely. I have written a letter to GM demanding the buyback of the vehicle along with explaining all of the problems and concerns. (remember to keep copies of everything) I also went to BBB Autoline to file a complaint as I am working with them diligently. The manufacturer still has yet to do anything but try and "diagnose" the vehicle for problems that keep occurring. I am now using the lemon law to fight them! It has clearly gotten out of control with their lies and I am tired of it. I should not pay for a car that does not deliver what is promised and puts me and others in an unsafe, unreliable predicament. I will now be using the Magnuson-Moss Warranty Act under the Texas lemon law to finally put a stop to this. If you do not fight for yourself these companies will continue to deliver poor customer service and promises to a naive consumer who trusts them! It's time to do something about it, and I will!

So sorry to hear of your troubles. Actually, we really like our LaCrosse. I'm just looking for an affordable way to read my mileage again!

Yeah it is a shame indeed, a shame that GM DIDN'T listen to their customer... Don't get me wrong I love the car... it's just one of those... and one of those companies that obviously doesn't care.

Sorry for both of you. The lighting is controlled with dimmer circuitry. I think that includes the mileage reading. Do you have HUD? NAV is included on the CXS if I remember correctly.
Anyway, the different lights would require different variables to keep the sources approximately the same level. That is likely a panel with several controllers run in parallel from the dimming control. It sounds like the possibilities are that the circuit for mileage inside that box could be bad. The output from it is wired to the dash group including the mileage readout.
So three possibilities. The controller box, wiring, and/or the unit containing the readout. It should not require removing the entire dash to replace the units, but the wiring is a different situation. That is, it depends upon what GM requires as a warranty fix.
And there is a big part of the rub. It might require replacing a major wiring harness. The more that is taken apart, the greater the chance of something else being broken. That is the mechanic would be required to follow GM procedure, but may not. GM procedure could be incorrect, written by some nummy who may have never laid a hand on a vehicle, and thinks that the same procedure for a different vehicle will work. Frustrating the mechanic, who may be under trained/experienced, you may get a botched job. But he will certainly try to make sure the dealer gets paid and anyway possible attempt avoiding a free re-work. And somehow the GM know-it-alls go along with that. They are so smart that GM and any of its parts make no mistakes. (That was the attitude I percieved from the GM district rep, even when you could clearly show him the difference between yours and a working vehicle.) Alas, GM also took the attitude that if they are alike then it is not broken. Reality being they are all broken.
Hope this helps in determining if they have been trouble-shooting properly or changing correct components, etc.
BTW, see if the boots on your rear shocks have fallen and see if you can get them to fix. Please report back. The issue is that the fallen boot will lead to early failure of shocks, albeit maybe not until after warranty is expired. And if you have the touring package, that might be a very expensive job because of the full time electronic suspension.

Just got a 2011 lacrosse csx they tell me just push the fog lamp button when the lights are on and in auto they will always come back on.
Guess what they do not.. If i shut the car off and turn it back on with in 30 sec they do but if i go in the house or store work when i come back out turn on the car just the headlights come on.Think it's cool how you see the headlights go through there test by moving right to left i see them on my garage door.What i'm trying to find out should they come on after doing what i'm told about pushing the button when the lights come on Thanks

I don't remember exactly, but I think they went off. Check your manual to be certain and if you can find them, download a pdf version which is very searchable.
One of the nice points is the button to turn on. A large round button that only takes a tap to activate and is easy to locate by feel so no time "eyes off the road" needed. Wish my MKS worked that way. Large round button, but have to pull-push for on/off.
BTW, does yours have the fallen down boots on the rear shocks?

Good morning and congratulations on your 2011 LaCrosse! We hope you're enjoying your vehicle so far!
 
In regards to the fog lamps, if the fog lamps are turned on while the exterior lamp switch is in the AUTO position, the headlamps come on automatically (p.6-5 in the manual). Looking at the section on the automatic setting for headlamps, it does not seem to affect the fog lamps.
 
If you do have further questions about your new vehicle, we'd all be happy to help!
 
All the best,
Sarah

They come on if i turn off car for more than 5 minutes they will not come on until i push the button again.This is what i do not want to do everytime i get in the car. could you ask a mechanic if a relay could be faulty.Thanks

My 2012 is the same way.
 
You do know it is not preferred to drive with fogs on all the time correct?
 
The short throw of the lighting directs your attention from further down the road.
 
This can explain it well. DanielStern Lighting
