2006 Buick LaCrosse Question: DCS - Dashboard Lights

 

Question

Early in the morning, after sunrise, and again in the evening, before sunset, the dashlights,odometer lights, radio lights will not come on if you are driving west in the morning, with the sun behind the car and vice-versa in the evening. Once the sun is higher in the sky the lights work. Have taken it to two dealers and called the BUICK 'help line'. They all say there is nothing that can be done it is just a 'flaw'. BUICK gave me a year's worth of oil changes to 'go away'.
Thanks for your help.

    Hello,
    Did Buick ever figure out what was happening with your car? Have they heard this complaint from other LaCrosse owners?
    Thanks!

    I have the same problem with my 2006 cxl. It would seem that if they can build them they should be able to fix them.

    sorry I don't have an answer; but, we do have the same problem. took it to the dealer and they said they would fix it but it is just the same as it was. our 98 Regal GS also has a DIC with similar problem. if I should find out anything I will let you all know; and, if anyone hears more I would appreciate a response. Thanks...

    When I bought my 2005 Buick LaCrosse, one thing the salesperson said as he was going through the car's operation with me was that this was designed in on purpose, where if the sensor detected a certain situatiion, the system dimmed those lights to reduce glare. I take issue with that design, as to me those lights don't add any glare; but that's what I think is happening there. By the way, I think the Buick Lacrosse is a great car.

    I have an 05 LaCrosse and it works the same. The sensor that automatically turns on the headlights does so when it can no longer pick up the suns rays. When the headlights go on the dash lights dim to the night time level. This level is plenty bright at night but when the lights first turn on it is so dim that it appears they are not even lit.
