Why Are there so many problems with my 2012 Buick?

I guess it's anything after 1970 which is a long group of POS from all manufacturer's. From another poster I'm wondering if Canada is considered a foreign country and any vehicle from there is also poorly made like a German GM vehicle, good thing GM didn't import the Parisienne LMAO.
 
People seem to forget that the old engines like the 3800 didn't have to adhere to many of the absolutely ridiculous emission regulations that we have today, and companies are forced to design and install secondary air systems, etc., all while still having to stay competitive...
 
A bad bearing will make a low pitch humming noise. My wife had one replaced and it failed a little over a year later. She doesn't drive her Regal hard so evidently it's a quality issue with the GM bearings. I had one replaced in the rear of my Regal too.
Unbelievable! I suppose--in the eventuality my bearings do failure--I could buy a superior quality set of rear bearings through a third-party parts supplier and have my "reliable" mechanic install them. It's really a shame that Buick dealers are increasingly perpetuating a second-rate and unreliable repair reputation...truly an accurate reflection on GM's "quick-buck" ideology.
 
Don't forget to mention the Corviar, Chevette, Citation & Monza! They were all doomed to fail from the beginning!
Sadly, it's amazing how GM (and other US auto brands) + slick advertising campaigns have duped the American public for a century! I suppose by now they know we'll never learn.

Actually, Pontiac was selling Parisiennes here in the states in the early 80s.
 
Thanks for the correct update, but it was all tongue in cheek as to what some people consider foreign. Seeing how Holden vehicles came in as Pontiac and Chevrolet I guess I should have mentioned them also, darn foreigners lol.

The OP seems to be one and done on this post so the exact problem may never get resolved.
 
I've got a 2012 Premium III with ~94k miles and have done little more than routine maintenance...had a few minor things taken care of when it was under warranty (bought as a CPO in 2013...car had 11k miles). I hit all the recalls and also had a belt tensioner replaced I think under warranty. I'm changing oil myself when indicator gets down to 25% oil life...close to 10k miles.

What recalls? What are the symptoms of a bad belt tensioner?

Which engine do you have? If you have the Ecotec engine, I highly recommend doing oil changes more often than 10K miles.
 
Thats too bad! Hopefully your able to fix the issues your having. The community here is great and full of knowledge. I dont know much about the 12's. I own a 16 and I've had my fair share of issues too. Alot of it was dealership related. I'm going to give this car a fair shot though!

Absolutely, this new trend of manufacturers recommending 7500-10k in between oil changes is absolutely ridiculous
 
With my 2011 2.4 I did full synthetic every 4000 miles. My reward was that the transmission blew up instead.

No it's not ridiculous it's true, motor oils are much more advanced today and they can easily last that long while still lubricating the motor properly.
 
The 10K oil change may be fine for having your car last 150K miles. Even if you make it past 150K miles, it might not be as efficient as an engine that had more regular oil changes. I like to get at least 300K miles on my cars! The majority of the people with 1 million miles on their original engine used 5K or less oil changes.
 
I have seen an oil analysis of synthetic oil after 7500 miles and there was still life left in the oil. That is real world results not just speculation. This is 2020 not 1980 so obviously some of you need to get up to date on the longevity of motor oil.

Why wimp out at 7500 - 10K range, go big or go home Mobil 1 Annual 20K
 
Well I do remember reading somewhere that GM had to update the oil life monitor for the 2012+ cars because infrequent oil changes led to stretched out timing chains and caused major issues. So for me I'll stick to 3k oil changes.

First of all, these oil analysis tests do not give a full picture of the protection of the oil. Do they test the dynamic wear under load at operating temperature? They do not. In fact, for the sample report they have on Blackstone, the SUS Viscosity is below the normal values with around 5K miles. I wouldn't want to push that any further than they did there.

Also, they do not take into account other aspects such as properties of the tensioner guides. Exactly what property of oil that keeps them failing is not known at this time. I do know that more frequent oil changes will prolong their life. Hence the reason GM changed the oil change mileage interval in later years. They do not even include TBN or TAN values for their basic test.
 
Oh yes it's 2020 but manufactures still make corrections on OLM. It's funny that it's the owners who will be responsible for this error after the warranty is over.
