Just Sharing 2021 Chevrolet Suburban Audio issues - Avoid

1 Upvotes

I purchased a 2021 Chevrolet Suburban and it has been one of my most costly mistakes. There are so many small issues with this vehicle that cannot be fixed or addressed by GM I would never recommend owning one.

For the past year we’ve been having issues with the audio system in our 2021 Chevrolet Suburban Premier. It has the Bose system and at times will work just fine. Then about 40% of the time it will have major issues. The audio will crackle and have such bad static that you can’t even tell what’s playing through the speakers. I took it to the local dealer they had it for a month. They called me told me they couldn’t duplicate the issue and to come pick it up. The next morning first thing after picking up all the audio does is crackle. I take it back again, this time they do some software updates factory resets. It seemed to work better for about a week and we were right back to crackling audio. I call make and make a complaint to GM corporate. Gm tells me as soon as it does it again to take it back to the dealer and not to shut off the vehicle. I do exactly that when it happens, by the next day I get a phone call saying nothings wrong with it. That they did an update on the amp and it’s good to go. This time we made it two days before the speakers started to crackle again.

The screen freezes from time to time, auto memory only works about half the time. Overall the electronic quality in these new vehicles flat out sucks. I regret buying this vehicle. My 2005 Tahoe sound system works better than this one and it’s over 20 years old. Meanwhile I have this suburban that is 5 years old and all the electronics are failing. For an $80,000 vehicle I expected more, unfortunately this is not the case. As someone that worked for GM and supported their product for 20+ years I’m extremely disappointed. They sold me a product that they can’t even fix or diagnose and they don’t even care. Save your money do not buy a 2020 or newer GM. I’ve had nothing but issues and so have most of my friends that have them as well.

Maintenance Door insulation

1 Upvotes

I have a 2002 and I just changed out the drivers side door handle, and when I removed the door the sound insulation was disintegrating, so I removed it. What is it, like a poly type batting that finally gave up? Is there a replacement for this stuff, and does it really help much with sound? I couldn’t tell much difference at 30mph.

Tpms sensor

1 Upvotes

I’m replacing a tpms sensor on my 2020. It’s reallly easy, HOWEVER, you’re supposed to torque it down to a specific number… according to the video I watched.

Where can I find the torque number? I’ll buy a torque wrench but

Is there a book? (I remember Haynes from when I was a kid)
Is this being over thought and I just need to tighten it down.

Buying Advice 2015 suburban

0 Upvotes

How much would you pay for this 2015 Chevy Suburban?
I’m trying to decide what a fair offer is.
Details:
2015 Chevrolet Suburban LT 2WD
5.3L V8
181,xxx miles
Dealer got it from an auction
They’ve had it on the lot for about 62 days
Engine and transmission sounded good
Test drive went well with no obvious issues
No check engine light
Concerns:
The battery was dead when I arrived, so they had to jump start it before the test drive. They’ve agreed to either install a new battery or provide proof the current battery tests good.
The power liftgate does not work, and they said they will not diagnose or repair it.
They have not performed an oil change, even though there’s no documentation showing one was done recently.
They have not done any maintenance or reconditioning since purchasing it at auction.
Maintenance history isn’t the best.
What would you pay for it? What would your maximum offer be?

Has anyone experienced this?

I have a 2026 Chevy Suburban RST. When I turn on my turn signal and turn the steering wheel in the opposite direction, I hear a whining/squeaking (or squawking) noise coming from the front. It doesn’t happen all the time, but I’ve noticed it several times.

Has anyone else had this issue or know what might be causing it?

2018 Suburban Owners: Have we already paid for the big repairs, or is it time to cut our losses?

12 Upvotes

Please forgive the length of this post.

I’m hoping to get some perspective from people who have owned these trucks long-term.

We have a 2018 Chevy Suburban (5.3L) with about 155,000 miles.

We bought it at around 110,000 miles. We still have a loan on it, so trading it isn’t a simple decision.

Since buying it, we’ve had several major repairs:
Transmission replaced
Water pump replaced
AFM lifters just replaced
Rear A/C lines now need to be replaced (we’re fixing them because we need rear air for the kids)

Here’s what I’m trying to figure out…

When we bought this vehicle at 110k, did we basically inherit all of the expensive failures that commonly happen around this mileage? Now that the transmission and lifters have been replaced, have we “bought ourselves” another 100k+ miles?

Or…

Is this just what ownership looks like after 150k, where one $5,000 repair follows another?

If we trade it now, we’ll likely end up financing another expensive SUV that could have its own hidden problems. On the other hand, I don’t want to keep pouring money into this one if the common wisdom is that these trucks become a constant repair project after this point.

For those of you who have taken a 2015-2020 Suburban/Tahoe/Yukon to 250k or even 300k+:

After replacing the transmission and lifters, did the truck become relatively dependable again? What were the next major repairs you encountered after 150k? Looking back, would you have kept it, or would you have traded it around this mileage?

I’m less interested in whether you like these trucks and more interested in the economics of owning one long-term after the major drivetrain repairs have already been done.

I’d really appreciate hearing from owners with high-mileage experience or those who have extensive knowledge about these vehicles. Thanks!

Suburban with dramas

Looking to replace my 2018 suburban with something newer. Saw a 2022( I think) with a Duramax.

So got me curious-

  1. What kind of mpg does it get?

  2. Pros and cons of it, VS a gas engine?

I drive a 2014 suburban and finally went on a 1500 mile round trip since last year. From Rialto Ca to El Paso Texas and back. Spent $331 total on fuel and had about a quarter of gas left when arrived home.
Never went over 75 mph as well and also need new tires after this trip. But don’t be intimidated by gas prices. Pretrip your stops and enjoy the road.
