I'm about 2 seconds away from returning this thing. I installed it myself and noticed leaks from all 4 corners. Brought it into the dealership and they reinstalled in incase I didnt do it correctly, which I've always put my own on and never had issues like this, however I had the old GM hard fold that sat on top of the bed

 

We finally had a heavy rain today to test it and this to me seems unacceptable. I've only had the cover for 4 weeks now.

 

I have the leer hf350m tonneau cover in my garage waiting to be returned but now I'm wondering if I should just return the GM one.

It’s rare for any folding cover to be completely leak proof, but yours seems pretty excessive to me. I have a LoMax and get just very slight leaks at the front corners. Again it’s very minor. If staying dry is important to you, I’d return it and look for another cover.

Hate to see it!!  One thing to keep in mind, no company that sells Tonneaus is going to guarantee no leaks.  
 

With the right amount of time, patience, and sealant you can get it there.  I have the MX4 (Bak version of yours) and it took time and tinkering to get it to where I have 99% coverage.   
 

4 tips:

 

get rid of the weather stripping they give.  It sucks.  Find something thinner and wider for the front.  
 

chop down / cut the drain tubes up front for the rails.  This helps and allow proper drainage for leak into the rails. 
 

wait until it’s sunny, crawl in the back with the cover on and close the gate.  Look for light.  If it’s at the rear, loosen up front and adjust the cover, If it’s not on a functioning joint - put some silicone on it

 

make sure the “flaps” on the side are flat and straight.   I had bad leaks from the side and noticed that the flaps were getting folded under. I rarely fully unfold the cover so just checking this when I close it again is easy enough. 
 

 

there is a ton of hate for the MX4 and it’s GM counterpart.  To each their own.  I’ve found it as great quality with great features (the full fold up

is a lifesaver), but it took me some TLC to make it that way. 
 

good luck!!

If you want complete dryness, get a cap. Never seen a tonneau of any variety 100% keep out rain.

I agree no cover is 100% waterproof however I feel like this is excessive maybe I'm wrong. My gm hard cover I had in my 17 denali never leaked as much as this. Although that cover was not flush and sat above the rails.

This cover has some big gaps at the front 2 corners

Yeah I got rid the the bulkhead strip that came with it. I actually have no seal on that right now and I'm getting minimal leaking from there. It's up and down the rails and corners.

I have the GM rev. The panel fills with water and leaks through the screw holes the hold the teather straps on. If tried different gaskets, silicone sealant, etc. I deeply regret my purchase. It has its strengths for sure but overall it's low profile design is not enough to outweigh the leaksd5e69e1f9c2daedbf6f8663605d7e65d.jpg

In my opinion, anything that sits on top of bed is superior for water leaking. Then you only have to fight water around the edge and not all the water that gets inside from the flush mount with a gutter system. Also my Cabela's yeti type cooler fits with a 1/4 inch to spare under the rev cover. That extra couple inches that a sit on top cover gives you could be huge

I wonder if the design has changed over time. I had my cover installed at the dealer when I purchased the truck a year ago and it has never leaked. There was a recall on the tonneau earlier this year, so I took it off temporarily until resolved, the weather stripping looked superior to the Bak I had on the last truck.

I just ordered a Leer in preparation for a road trip this summer, where rain is to be expected at any moment here in FL.

I don't need it watertight, just enough to keep it from getting drenched.

Some drips are normal with any tonneau. The OP's is clearly excessive IMO.

Never had a drop of water in my diamondback! The other plus for me is the security of it. No coat hanger is going to open this one. Even a crowbar would take a long time. The rugged looks and cost are not for everyone I understand.However for what I haul security and dry are the most important things.

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
