Just a heads up to all the other 2019 owners out there.  Last night I noticed water on the top on the back seat on the passenger side and my rear window is leaking.  It looks to be coming from the area around the sliding window rail.  I spoke with the dealership last night and will be dropping it off today for them to fix.  I'm not really pissed off about it because this is the kind of stuff that happens when you buy the first model year of a new design but I just wanted to give you guys a heads up on something to look out for.

Well my 2019 early build leaker was replaced with 2020 hopefully not leaker. No signs of an leaks on the window or headliner of the 2020 so fingers crossed. Very impressed with the 10 speed after th

No leaker here so can't do a 100% verification, but the problem seems to be with the spoiler design, regardless of weather the sealer leaks or not, and any cracks in the trim make it worse.

That sucks but if you ask me this shouldn't be expected. A window leak should never happen on a new vehicle. Its not like this is the first trucks they ever built and they had this problem on the last models.

I too am a disappointed owner of a 2019 GMC Sierra 1500 Denali. Have had the truck about a month with 2K miles and the rear window leaking as well in the upper right corner. Headliner needs to be replaced and the minimum wait from factory is 2 weeks?!?! Didn’t notice the leak until a trip back from Atlanta in extremely heavy rain. How long had this thing been leaking? Probably from the start. I agree with the previous post, this should not be an issue an owner should have to deal with on a brand new truck, regardless of purchase price. Seems to me a water tight interior is a fundamental requisite for any vehicle. Poor quality control GM, hope you fix this issue at factory by recalibration of the robot that applies the sealant. Hope this is the only QC issue but I can’t help being dubious at this point.

I would want my vehicle replaced if I found out it was leaking. Knowing that the interior got soaked would ruin my ownership experience.

My sentiment exactly. That’s what I have requested and GM has yet to acknowledge. It makes me think this issue is more prevalent than we yet know. I’m afraid there will be a lot of unhappy owners dealing with this same issue. Thankfully, the dealership is top notch. Not sure if I can mention the name on this forum, but they deserve the business.

I remember my dads 81' F150 leaking from the quarter window and watching it trickle down the door onto the rubber floor and not effecting anything. These new trucks are disasters waiting to happen in so many ways.

I probably should have given more details but the interior didn't get soaked, it was just dripping in and I don't think it even got the carpet wet.  There was water on the top of the back seat and I just wiped it off.  Of course this should still not happen and needs to be fixed but there was no damage done to the interior.

It is the nature of the beast.

2019 T1 GM trucks have the same sliding unit as the K2 current/outgoing platform.

My '14 sierra slider does not "leak" , but rather water gets in at car washes on occasion. Just enough to sprinkle the rear seat top.

Especially if you use the want and spray at an angle from the side.

Other than that rain and normal wet conditions do not produce any leaking.

My neighbor has an F150 and his slider does the same thing.

A good friend of mine has a new RAM 1500 and his also lets water in at the car wash.

It wasn't leaking at the rail for the window, that was the first place I looked.  I appears to be coming in from the top of the window and was leaking while it was raining.  Again, not a huge amount of water but enough that it needs to be fixed.  The dealership said it looks like the seal was not installed correctly.

I got the same diagnosis from my dealer. It’s not leaking from the split window, but rather from the top passenger side of the glass itself. Bad window seal. Not sure if GM uses the butyl rubber or an elastomeric sealant, but this is definitely a factory defect. BTW, I’m sure we can all agree that any window that opens has the potential to leak if enough water pressure applied. However, a fixed window should not leak and each vehicle should be tested before rolling out the factory door...in my humble opinion.

Absolutely a sliding window has the potential to leak.  I agree that a fixed window should not leak but it does happen.  Now if this becomes a common thing then Chevy really has an issue that needs to be addressed.

Agreed. Both of us have brand new trucks about a month old with the same problem in the same place. Time will tell how prevalent the issue is as hopefully others find this post and share their experience.

In that case, watch out when you head to the car wash with the slider! :thumbs:

I have learned to just keep the wand away from that area at full pressure.

Thanks Sierra Dan, I hand wash and wax my truck once a week. Has never seen a car wash which may explain why the leak wasn’t detected earlier. Sold my 2 year old Canyon for $$$$$, still looked like it just came of the showroom floor.

I hand wash also, but use the want to soak the truck down first to remove any light dust.

Black is not great for auto car washes! LOL

      Scan Tool Recommendation

      By AndrewF · Posted

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.
