I have 2021 Denali 1500  7 month old.   I noticed  where the clear protective coating on the panel right in front of the rear tires, was full if chips, through the coating and the paint. I thought this coating was hear to protect the paint. I have not driven on gravel roads more than a couple times. Ther are no chips out side of the protective coating, pretty much start where the coating is applied . I showed the local  GMC dealer body shop  , and his response was " what do you want ne to do about it"  He was a real dick .  Just wondering if others have had an issue, or is this just normal wear and tear as the dealer seems to think.  Seems this shouldn't  happen in 7 month in normal driving  conditions

My 2021 is the same way. They won't do anything as the paint chipping is because of the way its designed. You can repair it and it will be the same way 6 months later.

I guess the Sierra does not come with the front-positioned mini mudflap in front of the rear wheels as the Silverado does? Are there aftermarket solutions?

They do but that does not help. This is in front of the back tire. Actually right above that plastic. Also it is not a mudflap. It is a wind resister flap. Installed to direct wind around the back tire for better aerodynamics. 
this is the reason I always get running boards, also because I need them to get in ha ha.

Thanks for the clarification. This is an issue I haven't experienced on my 2020 Silverado in 16,000 miles.  While the majority of those miles have been on pavement, I do drive on gravel roads occasionally.  But then again the design of the Sierra's wheel well is different than the Silverado's, but I have no idea if that is a contributing factor.

The design is the reason.  The lower part of the rear fender sticks out as seen in the photo above and road debris will hit this area.  Running boards do not help, I have them and have the same issue and never been on a gravel road nor do I have agressive tires, Bridgestone Alenza tires.

At 3500 miles, my (always on the street at that time) had 7-8 chips on each side ranging from 1/16th to 1/8th"

I'm going to drive it another couple years and likely dump it.  Totally not my thing as I usually drive them into the ground before getting rid of, but with how it looks already (at 6k now) I likely won't be doing GM unless they make some crazy changes to paint

Have it painted and then get paint protection film on lower half of the body......i just had mine protection filmed. Shouldn't have to do this...but seems like the paint quality just gets worse and worse.

The only problem is can't put the film on that area as the roughness of the rock guard ( as my dealer calls it ) would leave bubbles and look horrible, at least that's what I've been told by a few places I contacted.

 

I had the same problem on my old 19 Denali twice on both sides of the box. First time the dealer warrantied it and repainted the areas as it happened with less than 400 miles on the truck. Second time about a year later they worked with me and I had them take that rock guard crap off the box, repaint it and than applied the 3M film. 

 

My new 21 AT4 got quite a few small ones in that same area after driving 23 miles on gravel over the 4th weekend while attending a funeral, the only time I've been on gravel since I bought it. There seems to be a problem with the paint on the 19+ Sierras, pretty disappointing considering the price of a new truck

Flat and wide running boards will prevent this. (or at least a big percentage of it)

 

Mudflaps are a only a partial solution. 

 

For many years I always added aftermarket boards to stop this, but for starting have since decided it's just easier to have the wide/flat GM ones installed.

 

I like the current ones better than the ones that GM offered for used for many years prior. 

 

 

Lived on a gravel road for 25 or so years....including a bunch of years running GM boards.

Ditto on that when I was getting clear film from a well established installer in the area. Told me the same for the chrome.

 

This is really unacceptable. Have you all went up the chain to the regional level and receiving the same answer?

I had my film done by a reputable company in my area with Xpel film and you cant even tell its on that rock guard area.....its just as smooth as on the regular paint. I'll get some pictures when I get the truck back this week from getting it ceramic coated and then it's gotta go to the gmc body shop for a bed alignment....sticks out overd a half inch on passenger side by the cab and the bed lines and the door lines are not level. Check yours out to.....there's a gmc bulletin for it.

The 19 Denali I traded had to have the bed aligned but thankfully my 21 is even. I will check out the Xpel film, found a couple of places that install it locally when searching online. The ones I contacted only used 3m on said it would leave bubbles. I would like to get the film on if possible, plan on keeping this truck a while and don't want to have to fight paint chips all the time.

I already had 3 pretty bad rock chips on the lower front the front passenger door before I managed to get PPF on. My guy used 3m and also wouldn't cover the rock guard area. My chips weren't in that area anyway. I'm not sure when they occurred, before or after mud flaps and/or nerf bars. But the truck hasn't been off pavement yet.

      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.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
