Gas Pedal Flex Solution

I have been having throttle response and other issues since I got my truck in late October. I stumbled across this post, and checked mine. I cannot believe GM approved this design and let this off the assembly line, the flex is insane. The actual pedal moves about a 1/2" before it even registers the gas is being pressed. I'm not nit picking as someone said earlier in this post. I wish I knew how to get a video uploaded. This is unacceptable in my book.

 

Has anyone had the dealer look at theirs? I'm sure its just another "that's normal" issue.

 

Well if it was designed that way, then it is normal. Mine is this way also, I just push the pedal a little more. It is obviously designed this way, I don't know why, seems to be on spacers. It may be this way to reduce sensitivity. I've seen pedals so touchy that any little bump has the vehicle lunging and pulling up uncontrollable. I'd rather have mine this way than feel like it's a bucking bronco. It seems like there is a solution earlier in the thread if you feel the need to improve it, I'm leaving mine as is.

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.

Yes I will definitely making a solution for this, Just curious what the dealers have said before I put some spacers in. Its already lazy being wire controlled. No need for them reduce throttle sensitivity on these trucks any worse than they are. The flex of this cheesy ass design is just making it worse. Why its not mounted to the floorboard or a solid surface is beyond me.

Common GM. It wasn't that long ago that Toyota lost millions of dollars over a gas pedal, that in the end was perfectly fine. Turned out to be a bunch of idiots that can't drive cars. Figured after the camry gas pedal fiasco engineers would scrutinize the gas pedals moving forward. This is a legit POS gas pedal design anyone with a iphone can video and post on the net.

VEHICLE SPEED CONTROL: 2014 Chevrolet Silverado

Filed: 12/26/2014

 

WHILE MOVING FROM A STOP THE TRUCK SOMETIMES LAGS IN ACCELERATION WHICH MAY CAUSE THE OPERATOR TO DEPRESS THE ACCELERATOR FURTHER THAN REQUIRED TO ENTER TRAFFIC. THIS CONDITION ALSO MAY CAUSE A SHORT ACCELERATION DELAY WHEN PULLING INTO TRAFFIC THAT CAN BE UNEXPECTED BY THE OPERATOR. I HAVE BEEN SURPRISED MANY TIMES BY THIS OPERATOR DISCONNECT ACCELERATING FROM A STATIONARY POSITION. AFTER DRIVING MY NEW TRUCK 900 MILES I INVESTIGATED THE ACCELERATOR PEDAL ASSEMBLY BRACKET TO FIND THAT THE ENTIRE BRACKET IS NOT PROPERLY FASTENED STRUCTURALLY TO THE FIRE WALL BY DESIGN. I INSPECTED MY TRUCK ON 12/23/14 AND FOUND THIS PROBLEM, THE ACCELERATOR PEDAL BRACKET FLEX ON MY TRUCK LOOKS TO BE ~3/4" TO 1" BEFORE THE ELECTRONIC LINKAGE ENGAGES. THE PEDAL TIP-IN ENGAGEMENT HAS TO FLEX THE MOUNTING BRACKET BEFORE THE ELECTRONIC ACCELERATION SWITCH ENGAGES. I CAN'T BELIEVE THE GM ENGINEERING AND DESIGN TEAM'S WOULD APPROVE OF SUCH A FLIMSY MOUNTING BRACKET FOR THIS IMPORTANT PART OF BASIC MOTOR VEHICLE OPERATION. I FEEL OVER TIME AND USAGE THAT THIS BRACKET MAY COMPLETELY FAIL AS CURRENTLY DESIGNED. I COULD SHIM AND INSTALL ADDITIONAL HARDWARE TO CORRECT THIS SAFETY ISSUE, BUT I FEEL THIS DESIGN ISSUE SHOULD BE ADDRESSED WITH GM BEFORE SOMEONE HAS A CRASH OR WORST.

This is the video I shot this afternoon. Hopefully you can see the flex of the bracket. Sorry for the poor quality of the video. First one I have done.

The adjustable pedals don't move as bad. I'll make a video of it next chance I get.

Holy shat! Lol. I just went and checked mine out...zero flex..zero! Strange the difference. Wonder if later built trucks had a "fix"? Mine is 08/14

I own a 2014 Silverado LT 4x4 double cab V-6 with a build date of June 2014, I do not have adjustable pedals, my pedal bracket flex is insane.

 

I noticed the lag in accelerator pedal tip in response from my first test drive of my new Silverado from day one with 18 miles and still have issues at 900 miles.

This design problem isn't going to correct it self and will only get worst from usage.

 

I don't know from reading all of the threads and posts which 2014/2015 build dates and models are impacted, but I think once owners can see the bracket flex in their trucks they will only then understand the issue.

 

This issue seems to be for the fixed pedals only and not for the optional adjustable pedals.

 

Happy 2015 !!!

Just checked mine. Non-adjustable pedals, surprisingly little flex. Only about 1/8" at the most. I wedged a piece of rubber behind it anyway.

My '15 doesn't have adjustable pedals and the bracket doesn't flex like depicted in the video when pedal is pushed downward; its build date is 9/14.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
