Hi all, looking at picking up a 2018 lacrosse fwd with the 3.6L v6 with around 50k miles, but was wondering if there were any recommendations for exhaust systems, most likely mufflers or a cat back system. I am aware this shares similarities to some Cadillac models like the ats and cts, and...

Mice chewed through wire harness in the trunk on the passenger side that goes to the right tail light and the parking sensors. If someone has a diagram or could point me to where I can get one, i would appreciate the help. If anyone has the part number for this harness that may be another option...

First time posting, but I've tried compiling as much information as I possibly can for this post to hopefully not waste everyone's time. Vehicle Year - 2012 Vehicle Model - LaCrosse Vehicle Trim - Premium Engine - 3.6L V6 (Flex Fuel option, but has never been used by me.) Mileage - 118,978...

Great video around failing hybrid generator with codes P0A3F P0A40 P0C53 P0C5D P1B03. Also, 12v battery is not charging. Previous mechanic had replaced the generator and a related module in the trunk. Problem was traced to corrosion at the 12-pin generator connector (located on the right side...

Hello. I am looking to install Brembo brakes off a Cadillac XTS to my 2014 Lacrosse and have a general question regarding brake hoses. The Brembos bolt up without issue. My main problem is the brake hose. It is not long enough. The length for the hose is 20.30 in long. The length for the brake...

Hi guys. I have a few codes coming on a regular basis on my 2010 lacrosse. For the engine it's a p2017 , and fuel control module mil code. And the fuel pump control module has a fuel pressure sensor code. However randomly when I start the car it will do the stabiltrac routine that plagues these...

Alright, so I just purchased a 2006 Lacrosse. I want to find some steel wheels so I can mount a Falken Wild Peak tire in either a 215/76r15 or 215/70r16, depending on what wheels I can find. Finding wheels seems to be a challenge with the 5x115 bolt pattern. I would like some offset to at least...

I have a 2015 Buick Lacrosse Leather and have noticed the fans being weaker than usual lately. I don’t know what’s wrong but I’ve done some testing and trial and error and this is what I’ve learned: - When I press auto, the dash vent and floor vent lights on the controls turn off, and if I turn...

2014 Buick Lacrosse 3.6L V6 115k Miles (Issues since 90k though) Bought my car less than a year ago from a Buick Dealership and started having intermittent problems maybe a week in. I had a gasket leak sealed and the ECM replaced (which wasn't covered under extended warranty). I've taken the...

My parents gave my 17-year-old son their old 2010 Buick Lacrosse CXL AWD 3.0L with 83,000 miles on it. There is a small leak between the engine and transmission. A mechanic suspects it's the rear main seal and quoted $4,300 to fix it, which we cannot afford (I am a disabled veteran). I...

For a few months now I’ve been having an issue with my LaCrosse starting up. If I don’t drive the vehicle for awhile and decide to drive it, it starts right up. If I turn the vehicle off at let’s stay a gas station or store and try to start it again, it struggles and the engine might not start...

I've posted here before about a temperature guage issue with fans on high all the time. I found out if the temperature is low enough, it will register that temp, but will turn the guage off until one resets the engine light, whether there is one on or not. Turned out my temp was low, even...

Alright everybody, I've got a weird one I've never seen before. Hopefully someone can shed some light on this. I have a 2017 LaCrosse 3.6 and about a month ago, the coolant temp guage started to intermittently drop all the way down and the fans kick on high. Now, normally I would think a...

I'm changing the thermostat on this LGX 3.6. In case I have to go back in, are the rubber intake seals reusable, or do I need to order an extra set? Thanks everyone

Hello, I am looking for a different set of rims for a 2014 buick regal gs. I found a set of rims off a 14 lacrosse. They are 19" chrome rims (I'll attach pics of them) and I'm curious if they would fit and clear the brembos on the regal gs. I remember seeing posts from regal gs owners buying...

Hey guys/gals! I have an 05 LaCrosse(Allure) with the 3800 series 3 v6, and while checking around my engine bay, I came across this disconnected wire, if anyone can tell me what it is it would be much appreciated 😄👌 Apologies for poor picture quality, I couldn't upload them at any higher...

Was patrolling the junkyard looking for goodies when I stumbled upon this gem. A 07 Lacrosse with a spoiler I've never seen .. sadly was cracked in a few places, so I couldn't use that one. so I am looking for this spoiler. Anyone know where I can get this gem?

i just purchased a 2008 lacrosse cxl, and i’m just kinda bored with her. i’m not used to it because i could race and have fun driving my old 2009 impala LOL. acceleration is just really slow in comparison. i know there’s not much you can do with the functionality/performance of the buick...

So my driver low beam headlight went out on my 2013 Buick LaCrosse. I bought the 100$ HID bulb, took the bumper & wheel walls off (pain in the ass) got the bulb in and it came on for less than 5 seconds & went out. Bummer. I’ve checked the fuses, they’re fine. I then realized the assembly...
