Gas Pedal Flex Solution

[neokonig]

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.

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.

Looks to be the same as my '15 has.

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!!!!
