Buick Forums - The Buick Owners Group

Most people either inherit or develop car preference based on unscientific parameters.
Without being a garage mechanic in an independent service station it is unlikely that people will be able to offer anything but opinions based on lore.
Buick has had some years and models that have been JD Power favorites, and others that have been poor.
Do not let some one else's perception of quality keep you from having a good experience.
Here is a link to a site that charts after purchase complaints.
Looks like the 2015 Lacrosse was fairly reliable.
Be sure to look up the Toyota you have to see how that did as well.

I have used 20 year old GM cars as primary transportation, you need to know which ones are the winners though.

Buick LaCrosse Problems

AlexMK335 said:

Recently running into a bit of a strange issue with my 2019 Encore Preferred. Have had it for 3 years now and up until the last month, I never had any issues with the infotainment system. However, recently there will be instances where the infotainment system (screen, radio, etc.) do not shut off after the car has been turned off and the driver's door opens. It is not consistently occurring and the majority of the time the infotainment system shuts off as normal. Any ideas on what this may be or if anyone else has run into this issue? From what I've gathered, it seems like it may be an issue with the retained power accessory (RAP) or the body control module (BCM).

When this happens do the interior lights remain OFF?

Yes, the interior lights stay off!

Guess is the switch in the driver's door latch is sticking

You can try searching by GM Part number 15225228 there may be a few floating around, but it's discontinued. Junkyard is probably the best route to locate any.

Thank you! That's the exact part I was looking for. Yeah most places arent selling it online, but I can try my local junkyards. Worse case, I can see if there is anything that would work with what is out there in non-unique parts.

I found an ebay listing, but its $22 per part and they have exactly 1 on hand 💀

You know there are people who would buy this. 😛 The only reason I would not is because now I'm too paranoid about getting an upset stomach - or worse. 😛

This car has been sold and is no longer available

According to my dealership's Service Manager, the problem is indeed caused by some blocked filters within the sunroof drains. The filters were originally owner-serviceable, but the tale goes that owners felt that was not adequate, so they were changed to dealer-only serviceable filters. My dealership says I should just ask to have the drains checked whenever I go in for an oil change, which (so far) has not resulted in any extra charge. Seems like too long an interval: we'll see which comes first. Also seems a bit crazy, if I'm just waiting for the car to flood instead of having any warning it might happen.

Appreciate this info. I have a 2018 TourX and today while driving in the rain, the car started calling OnStar SOS over and over. Then the overhead console started dripping. I suspected a sunroof drain issue. Proving my better half right that a sunroof brings trouble!

Sorry to hear this about your sunroof clog, but glad you got it figured out. I had this problem in my '07 RDX (parked under trees in my driveway for 12 years of ownership)...and it is why I did not get the roof option in my TourX. Although I do miss it, I have to remind myself no sunroof is the price of trees for me! (That, and about 4-5 rounds of leaf cleanup in the fall, LOL!)

HOWEVER, even without the pano roof, you will be astounded at the amount of debris that collects in the TINY crevice adjacent to the roof rails!
The only way to clear them out is with water blast or compressed air (or maybe a shop vac....)

Update: I got my TourX into my local mechanic before the dealership could see me. He was able to clear the drains and it resolved the issue completely.

Ha. Tell me about it. I blast all the crap from those channels every time I wash the car. 🤣

In the process of unclogging the driver's side front drain. When I popped the hood, I noticed that the grommet that secures the drain hose into the hood is missing. I can pull the hose through the opening but was hoping not to have to replace the entire piece. Does anyone know if that piece is detachable from the hose? Or am I going have to replace the whole thing?
Thanks

Depends, GM original bolts were 3/8" allen head. Most of the aftermarket replacements can be 14mm hex and chinese ones 10mm hex. Best is turn turn wheel all the way left or right and take a look, easy to see. After 30yrs only way to know

I know that some GM cars do have metric as well. Is there a possibility they could be metric? I'm not sure where this Buick was built. I just know that my '84 Camaro was built in Canada and it has a lot of metric bolts and nuts on it. And not being as young as I used to be makes me want to limit the amount of times I lay on the dirt to get under this car. So, guess I am wondering if a 10mm Allen would fit in the bolt head.

Very good tool vendor....

Oh, the wife caught me looking at the tools. 🙄 Uh oh.

Looks like Harbor Freight for me. lol

harbor freight hand tools are ok. Just be careful of tools that plug in, lift or support.

Lucky for me all I need is the Bit Socket. However, that cannot be better advice. Harbor Freight power tools are not very good.

I think a grade 10.9 M12 x 1.5 thread bolt would work if you can find it in or cut it the correct length.

My understanding after some deep digging is that the original bolt on the 2005 Century is not Torque-to-Yield (TTY). I am just seeing 10.9 class fasteners were used. If this is the case, then you should be able to re-use your old bolt with some medium blue locktite after a through clean of the bolt and bolt hole. Torque should be 80 ft-lbs. Cylinder head bolts are all I show that are TTY that I see.

The bolt is TTY. Here are the buick century specs.

Here is a link to a Grade 10.9 M12x1.5x45 bolt -


While it is not TTY, it should be strong enough for your application.

Or, you can order ARP M12x1.5x45 bolts from Summit Racing - https://www.summitracing.com/parts/arp-664-1005?seid=srese1

I think this is the best alternative. I have heard very little negative stuff about ARP, and there is a decent chance the replacement will not be TTY. A re-useable replacement would be ideal in either case. I don't do wrench work professionally anymore except for myself these days. I do deal in obsolete auto parts though.

I do know that at the dealership near by, they reuse those bolts for what it is worth. I also know I have reused them too at our shop with no issue, not to say that it can't happen. All things are possible. However, if a ARP replacement can be found, then that is great. The 3.1L was a very heavily used engine across GMs lineup for several decades, the possibility of there not being a single option makes very little sense. I know that engine was used through and may have been phased out just after the 2005 model year, which I think was the last year before it was replaced by the 3.4L. I think, it's been a minute. All that said, there were millions of those engines and it's variants floating around world wide.

If Dorman does not have one, then making a plea to ARP to produce one specifically for the 3.1L with torque specs should be considered and may take the community to back a representative or just flood their inbox.

Have you looked @ RA?
