I'm going to the dealer on Thursday to get it looked at. I will let you know what they say.

I took mine to the dealer previously, they couldn't reproduce it, as it only happens occasionally on my truck.

After noticing the gas pedal has a lot of travel before it actually starts to work, I looked at it closely. I noticed it's a very bad design. There is a plastic bracket that is bolted to the floor p

I agree that a good video would be worth a million words of what the problem is and where it's located.   I filed the NHTSA complaint shown below:     VEHICLE SPEED CONTROL: 2014 Chevrolet Silver

I can't believe this post is still going strong almost 3yrs later. Glad my fix is helping others.

A shot of WD40 on each side of the pivot point should eliminate that, it worked for me.

Apparently Chevy is going to replace my pedal. They said they couldn't replicate the noise.

I hesitated to post this but figured I might as well as it's at least mildly related. I noticed today that the throttle response on my truck is very dependent on my foot placement on the gas pedal. I tend to keep my heel between the gas pedal and brake which lets me rotate the top of my foot between the gas pedal and brake. This basically means that I'm pushing on the bottom of the gas pedal. I happened to put my whole foot on the gas pedal in basically a vertical orientation and the throttle is much more responsive.

 

I've probably driven this way my whole life and never noticed that any of my cars were sensitive in this manner. My truck only has 400 miles on it but the throttle response has always seemed very slow unless I really pushed on the pedal. With my foot position adjusted, the throttle feels a lot more responsive. I feel a little goofy writing this but figured it couldn't hurt to throw it out there.

I have the same issue, I broke my ankle back in the day and the foot has a slight right turn to it, so I always have put my foot where you are describing, and have noticed the same thing you are talking about.

My '15 (build date 3/10/15) w/ adjustable pedals has an amazing amount of flex when pushing the pedal down. I need to find a small piece of .250" thick rubber to try this with mine.

Old big rig/dump truck mud flaps work GREAT for this. My buddy is a mechanic for the PA Turnpike and picked me up one. Cut off a nicer section of the flap for a 2"x1"x0.25" piece and it works great for fixing this.

2016 owner here (10/15 build date) - looked at mine after reading this, mine looks completely different But I do have the adjustable pedals.

 

Anyways mine looks more like a plastic cage/box and seems pretty sturdy especially at the bottom bolt everyone is referencing to shim.

 

See attached picture, note bolt at bottom and depth of plastic box coming out around it, this appears to be a different design.

Bumping this thread because there has been some discussion about lack of power with the 5.3 liter. I firmly believe that everyone should implement the fix found in this thread regarding the gas pedal bracket flexing. It made my trucks "throttle response" much better--it was never an issue with AFM or the engine/tranny, it was the gas pedal flexing!!

You put the piece of rubber under the pedal or do something slightly different?

damn, noticed this thread and shoved a paint stick behind it. Still some flex but not as bad. Definitely noticed the difference.

 

Someone should take the plastic housing out and 3d print a new one. It's astonishing they found that amount of play acceptable. It looks like it was done intentionally!

I cut a section off an old round table leg. A disc of hardwood about 4cm across and 1cm deep. Inserted at base of the plastic bracket assembly, pushed up behind it. To give yourself room to push it in, pull OUT on the gas pedal. Insert your chosen shim (imo, hardwood is the perfect material). Then let go of the pedal. The bracket will fall back against your shim and the flex will be gone.

I didnt even have to secure my shim in place. It just sits up here behind the bracket. If you make it big enough, it just wedges itself in there and doesnt move. You cant see anything once its in either.

I have a 2016 regular cab, no adjustable pedal, had same issue. I loosened the 2 10 mm. nuts that was on cheap aluminum bracket & stuffed old rubber floormat under right corner, tightened it down, no wobble anymore. Have not driven it yet, have a 55 mile round trip to work tonight, am confident this will help, will let everyone know. Gas pedal should not flex on ANYTHING! , nor should brake or emergency brake pedals for that matter. Very cheap design, probably done on purpose for throttle response.

Well, after driving truck to work & back, fixing the pedal made a huge difference. Truck does not hesitate when initial accelerating. I highly recommend everyone to look at there pedal & modify it. You will notice a difference. Thank you FL335i for bringing this up to everyone, would have never known if it wasn't for your sharing of information!!!! :driving:

      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.
