It is a giant piece of plastic bolted to a giant piece of medal

They expand and contact at different rates

And it is bolted it isn’t taped or glued or put on with trim clips

You gotta drop the headliner...

I dropped my headliner to fix my rear window leak.  No loose fasteners.  No matter how I tried to mount the spoiler back on it was a bit off.  So I guess that's just how it is.

Any tips or tricks to dropping it?

Remove the rear headliner section

Remove the C and B pillars

Then pull down

You’ll make a crease in the liner but it’ll go away just don’t be resting your arm on it too much when servicing the spoiler

How is the headliner held up to the roof, clips?

I did the whole thing.  A, B, C pillar.  No tricks.  Just remember to put the driver seat all the way down before disconnecting the negative battery terminal.   
 

The upper center console, where the Onstar button is has two front T10 screws way up in the plastic housing.  That was the hardest to get to and hardest to put back in.  I would leave it on next time and not even drop that thing. 
 

Fairly easy otherwise.  I think it would take me 20-30 mins to do it again.  Faster if I was just ripping panels off held by clips without any regard.   
 

After taking the pillar panels off.  Really it is the visors, the two rear coat hooks on each side and the center rear light, which you just held in by two clips.  
 

Headliner itself only has two clips near the back rear window.  Mine was not clipped on since the GM tech worked on it to seal the rear window the first time.  And I wasn’t able to get the clips back in after my tear down either.  Oh well.  Doesn’t bother me.  
 

No other clips on the headliner otherwise.  It is tucked in snug into the weather stripping.  But still easy to pull it down.  

There is also a harness providing power to the third brake light/cargo lights partial glued on the headliner on the driver rear.  You won’t miss it.  Just pull down slower on that corner and disconnect it when you see it.  
 

I wore clean nitrile gloves or similar when touching the headliner.  You don’t have to, just be conscious about your dirty/oily hands touching it.  If you care.  
 

I recommend doing it.  It wasn’t bad.  And I was able to locate my leaks and seal them.

thanks! that knowledge could come in handy.

how hard was removing the pillar trim? I've done the A pillar before, haven't touched the others.

A pillar was probably the hardest of the 3 in my opinion.  B and C, pull from the bottom vertical or horizontal edge.  Don't start at the top.  Comes right out.

 

C pillar there are no bolts at all, only clips and a hook attached to a short (rubber?) line.  So pull with care.      

 

I used a plastic pry tool to help me get under it and get my fingers in.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By newdude · Posted

      I see some red flags.   - No mention in the Carfax if the oil pump belt was changed.  LM2s had a 150,000mi service interval, and its got 164,245mi on it.   - If something happens to the transmission valve body, the special coverage is expired by mileage.  That will likely be an out of pocket expense, with zero or near zero GM participation if something happened even though its in by time.   - 2020 LM2s seem to need timing chains after 80,000mi at some point.  They fixed this end of 2020/starting 2021 model year engines.     - Long oil change intervals.  7,000-8,000mi on average, probably close to 0% or perhaps to or beyond 0% on the OLM.  Lots of them not at the dealer which makes me wonder how much of the oil ran through that truck was the proper Dexos D rated 0w20 oil and not just gas engine 0w20, which is not the same at all.     - Long fuel filter changes, again likely taking the fuel filter life to 0% or more.  First one went 28,603, second was done 43,094 miles later at 71,697, from there another 46,452mi to 118,149mi, and then the most recent one 37,026mi later at 155,175mi.  So counting its original fuel filter, its had only 4 fuel filters on it.  No bueno IMO.     Good news?    - It has had only two warranty trips to the dealer.  The first free service (end of December 2020 on the Carfax), and the transmission reprogram recall (end of August 2025 on the Carfax).     - Truck did a LOT of moving, so that might explain the lack of emissions related repairs like bad NOX sensors, bad exhaust temp sensors, bad glow plugs, etc.     The "emissions system checked" could just be how something was flagged for Carfax.  GM dealers have to do SAVI reports for warranty repair orders so they scan the truck.  So its possible that is there for that?

      Thank you, @Z45!   NOTE - No all repair shop/Dealers reports to Carfax   That is my main concern.  The CARFAX looks way too clean for a 6 year old anything with 164,245 miles.  Even something known for reliability (like many Toyotas) typically has a lot more replaced, like a Nav screen, interior trim, shock/strut, or brake pads.  And surely the last set of tires (installed at ~58k miles) would be bald unless those were all highway miles.   I'm tempted to pay a local dealer to look up the VIN, but am not sure if that will be worthwhile.  Last time I did this, it was 100% useless, and I felt scammed - they noted the bumper was replaced years ago and that's it.  A 5-year old could spot the accident damage, even though nothing was on the CARFAX.   After giving the dealer a call, the truck may have a hard shift, but they have to verify with their mechanic if that's even a concern.  And I've test driven about a dozen of these now, many near Chicago, and half the trucks shift hard/odd at all throttle positions.  The ones with aftermarket lifts/larger tires shift terrible, and 3 stock trucks shifted so violently I thought the transmission valve body was going out.   At this point I'm conflicted, as I need a vehicle, and am coming up short locally.  Northern trucks in this price range tend to have either multiple owners, a lot of mods (lifts/oversized tires without re-gearing), and are generally in rougher shape.   If this truck showed up in your neighborhood for $27k and you had to purchase it sight-unseen, with the possibility of needing a 10L80 rebuild, torque converter, or rear end - would you do it?  I'm convinced most of the 10L80 trucks I test drove are broken, they can't all shift so bad, with massive flares/slipping/lurching and mis-matched downshifts like a teen driver learning stick.

      From the spy shots, the front end does look like it's borrowing some styling cues from the Canyon. I'm more interested in the powertrain news than the screens though. If the 3.0 diesel survives into the next generation, that alone will keep a lot of current owners interested.

      What is this tuner you mentioned that can shut the system off?

      I had it tested at the hardware store, and it showed no chip. He went out to started the truck today and it wouldnt fire. He waited an hour then tried again, and it started 3 times. In a row. My 2000 cavalier did not have a chip key, but still had a security system.  🤷‍♀️
