2005-2009 Buick LaCrosse: Keep getting a starting system disabled on 2006 Lacross

Tue, 14 Oct 2025 12:23:28 -0700

I keep getting a starting disabled message while driving my 2006 Buick Lacross. And it shuts off. Disabling everything while I'm driving… power steering and engine. I let it sit for a couple of minutes after I manage to pull over and then it starts up again. I also get a couple of other messages like service IBS system soon and service traction system also when this happens. Any clues?

2005-2009 Buick LaCrosse: How to change coupling for Battery positive wire?

Fri, 26 Dec 2025 10:51:26 -0700

The coupling is attached to the battery itself for the positive wire is very rusty and doesn’t want to keep in touch with the battery, resulting in the car “dying” after every time that it is turned off. I have a spare positive wire with the coupling but I don’t know how to change just the coupling instead of the whole wire. I also would like to know what tools are needed for this.

I had to replace my alternator in my car but once I did I noticed that I had a service theft system light and shortly after I had a charging system failure light and a battery light .

I know my new alternator is good I e had it yesterday from the auto parts store I purchased it at.

I know my battery is good because I just purchased that as well I don't know why my car continues to die on me and is acting like it had a bad alternator when it's good .

2010-2016 Buick LaCrosse: Headlight assembly repair, fix and save me 1500 dollars

Sat, 11 Nov 2023 14:25:25 -0700

How come you brilliant people haven't figured out how to fix a broken headlight assembly (new one 1500.00) when it needs probably 10 dollars worth of parts? I have a good headlamp assembly but 2 parts inside are broken. I will ship it to you if you want to experiment I have a 2014 buick lacrosse and the plastic and the holder broke. It's a sealed unit so you can't get at it. There has to be a way to get it apart and fix the broken pieces
