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?

Tue, 16 Jan 2024 11:17:20 -0700

My Buick's rpm gauge goes from working just fine to 0 in a matter of 20min. The car jolts a little bit when this happens and used to turn off completely while waiting at a red light/stop sign/idling. Can someone help me figure out whats going on?

Ive replaced the following:

Spark plugs/wires, fuel filter, serpentine belt, MAP sensor, Battery (brand new and 200$), gasket seals, oil change.

Thanks!

1997–2005 Buick Century: Why does my Buick sputter, accelerate on its own and is hard to stop?

Thu, 07 Dec 2017 09:48:03 -0700

A couple days ago my 99 Buick century suddenly started sputtering, backfiring and most the time will accelerate hard on its own while backing up, or pulling off from stop. Its cut off a couple times now at red lights. My brakes suddenly became hard to push in as well and is becoming harder and harder to stop. I know the two probably aren't connected, but can someone please tell me what it may be? Thanks!
