This pedal flex thing is real.

 

For the record this is a 2017 with almost 300 miles on it.

 

I shimmed between the plastic and the firewall with a piece of 3/16 steel about 1.25" wide and 3" long. It does not move at all now.

 

Here are YouTube links before and after

 

 

 

 

 

I've already noticed a more steady throttle. No lag due to it flexing and no harsh gear hunting from it flexing back or over throttling to compensate for the flex. This is a must fix.bc3d3edca2d71335bd06e8798360c8f9.jpg

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.

I have adjustable pedals and it was joke with the play/flex. I removed the whole assembly down to the plastic mount that has bolts attached to it.

I placed 2qty 1/8" thick plastic washers 1.125" in diameter over the 3qty bolts and put pedal assembly back and tightened down. I then took a plastic shim like a wood shim yet plastic and cut it down. At this point I pried up plastic mount and squeezed caulk and shim behind.

 

Took truck for "Hot Lap" and this thing now has probably 100% better throttle response! The best and first MOD evey body should be doing! Thanks OP why didn't I open this thread 1yr ago?

Excellent. So the adjustable pedals flex too? :driving:

I've been anxious to try this fix to cure what I think is crappy throttle response. I just started looking at the videos posted and mine doesn't move like that. It's fully seated against the floor/firewall area. I can pull out on the whole assembly and the pedal moves up with it. So I think there's an unfortunate group who have this bracket/assembly bent or warped, so it flexes down where it should be with any pressure.

 

Kinda bummed, because I wanted to do this fix and gain some throttle response.

The difference is night and day. I slipped a small wood shim behind and between the left side and bottom bolts, took it for a drive without even thinking... backed out of the drive way and nearly chirped the tires with the standard amount of throttle to get going.

 

thanks to the OP!

Your welcome. I cannot believe how many people have done this mod. I thought it was just me coming from BMW's and had a very different expectation for a pedal. Turns out is a crap design that my 4yr old daughter could of done in pre-school.

I have a 2015 5.3, non adjustable pedals. I pulled the carpet back a bit and was able to jam a wood shim in there and it achieved the fix (cant see it, does not look bad in my opinion. Much easier than a bunch of bolts). No tools, no cutting, didnt take anything apart. It was not night and day in my case, BUT I for sure do feel it improved throttle response. I feel more connected to the motor. Easy, quick, cheap fix for a bit more of a real feel into the machine.

I've done it now too. Cut up a plastic scraper and stacked enough pieces to get a good fit and wrapped some electrical tape around the stack before stuffing it between the plastic mount and firewall. Makes a huge difference when I'm travelling slowly around parking garages etc and am trying to to apply light throttle.

Picked up a used 2015 about 2 weeks ago and it's not as bad as some others I've seen here, but mine is maybe 1/8". Will mess with tonight and compare.

Shoved a small piece of 1/8" plywood up under there. Definitely a different feel (a better feel) on the pedal between pressing the accelerator to the engine's reaction.

Hey, I have the adjustable pedals on my 2018 and the entire pedal seems loose and moves loosely in every which direction. I'm not sure if I have a fluke or if this is normal between all of the adjustable pedal models. I had a 2014 with non adjust and it had minimal flex but I still did this mod. Looking at my 2018 It doesn't look like as easy of a solution.

 

Any way you could post some pictures or more detailed process of what you did? Would be appreciated if you did.

I have a detailed written instructions under one post! I am not great with computers but the instructions are EXACT and will help you very much.....It never fix the "intended" floating aspect of pedal but will stop the "actual flex in materials and delayed throttle responses enormously" My post is legit and more involved than a paint stick fix.....It's a fix that your never coming back to "fix again or it might have moved etc" good luck son! Stay away from the ecoboost's man I hate ecoboost's!

      New car smell air freshener

      I found an odor eliminator spray that neutralizes unwanted smells pretty well. Using it with the car's AC running helps to distribute it evenly around the cabin.

      WTI futures / speculation is just that. WTI futures <> current 4-7% inflation and national average gas price over $4.00/gallon.   The spot price, at delivery, is currently $87-$95/barrel which is why gas prices remain high.   Edit: oH mY gOd mEnTaL BrEaKdoWn In tHE pOsT aBOve mInE.

      He does, actually. In another unrelated video he mentions the president called him in the middle of the night to relay some information on a cause (religious based) that he's invested in. Glenn expressed concern that another leftist administration could wield too much power with some procedure the Pentagon was using, classifying certain religions a certain way. Being that he is LDS (Latter Day Saints), he gets hate all the time from ALL over the political spectrum, so he's invested in this. Trump called him back at 5AM to tell him he had made some changes to that classification.   So, yes, they are and have been in contact regularly since the start of the administration. Glenn, of course, always asks his permission before discussing anything on the air.   I already spent an hour or more just searching for these videos. I may have my numbers wrong - I'm not a numbers guy. It may have been a MILLION barrels, not 1.5. The point is, our President, by his actions, gives a crap about America, and US - this is completely OPPOSITE the actions of the prior administration who projected hatred for anyone who wasn't following the left's edicts in lock-step.   Remember, they called January 6th an "Insurrection", when there were ZERO weapons among the crowd, undercover FBI agents agitating the crowd, along with paid leftists acting as aggressors, egging the crowd on in an attempt to whip everyone into a frenzy. It's all been proven.  Pelosi refused Trumps request for more National Guard troops. This smells 100% like an inside job for those with critical thinking skills. Only a handful of guys in the crowd got wrapped up in that, thankfully, but EVERYONE was searched out based on cell phone data, and charges were brought against many. And 6 or so people were locked up and left in solitary confinement for YEARS with ZERO due process!! If you give the slightest crap about our Nation, REGARDLESS of your political leanings, this should frighten you to your core. This is what men suffered, bled, fought, and died against 250 years ago!   This has gone FAR BEYOND left vs. right. This is a  threat to America, and our way of life. This is PRECISELY why Trump, a BILLIONAIRE who could have chosen to take Melania and sit on some tropical island that he could afford to buy himself and RELAX, instead chose to run for office, get hate from literally every corner of the media, get ATTEMPTS on his LIFE constantly, and begin to repair some of the severe damage that's been done to this Great Nation.   I don't know why I bother wasting my precious time here. Everyone has their minds made up. They won't realize we all were correct until it's too late ... after they elect another tyrant that hates America to office (Obama), or another puppet whose administration is secretly running the show behind the scenes (Biden).
