Gas Pedal Flex Solution

[Silverado-Hareek]

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.

 

 

 

Wow that is awful! I thought I had "the flex" but mine doesn't flex that much. About 1/8-1/4" at most. You definitely need to bring that to the dealer's attention ASAP that is completely unacceptable. The fact that mine doesn't flex as much leads me to believe it may be an assembly issue possibly and it could be fixed somehow? I don't have adjustable pedals. Build date 9/2013. Rest of my vehicle specs under my avatar.

Wow...that is crazy! I have 2014 Sierra with a build date of 7/14 and mine has no "flex" at all.

Just put a washer under my bracket, huge difference when on and off the throttle! Thanks to the OP for posting this info!

wow... 2015, (build 10-14) non adjustable and that is shocking.

 

I would never build peddles like that on anything even a go cart, let alone a $40k truck.

When it warms up I will try to put a metal block or something back there to stiff it.

I checked mine and it had a good amount of flex before it engaged. Loosened the (2) 10 mil. nuts and popped a large metal washer behind the bracket. This took out about 95% of the flex. Prior to making this change I really had to mash the pedal to get the truck to get up and go. I was starting to get use to the mushie feel but like it much better with this make shift mod. I was really surprised how crappy the pedal setup is. Thanks for the info.

Here is a video of the adjustable pedals, you can see there is maybe a 1/4' movement before the pedal moves. My build date is early 2014 shortly after the 6.2L started shipping.

This is of the pedal movement. You can see the go the angle on the brake wrong so even though the screw is still moving the pedal stops, but the gas pedal is still moving closer to the floor. Silly they can't get that right.

I pried the plastic bracket away from the firewall at its lowest point and wedged a 1/4" thick piece of rubber. Works great, even with the small (1/8") amount of play mine had, the vagueness of throttle is mostly gone now. I highly recommened using something like rubber. If you use something metal, it has a good chance of rattling.

^ I used a paint stick for mine. The thick rubber is probly a better option.

Mine ain't broke, so I ain't "fixin'" it with a piece of stick and some goo.

I'm having problems viewing your video, can others view it??

 

Thanks

I hosted it on here, so something to do with the site. It was showing how the adjustable is not as bad. It flexes a lot, but it rests at the bottom of the flex making it not bad when driving. Then the bad pin placement of the brakes pivot point for the drive screw. I'll try and get it posted another way later.

Thanks, looking forward to another video that will show the non adjustable pedal bracket flex at a different angle.

Update on my paint stick. Have about 2k miles on it. Loving it. Truck drives so much better, especially in traffic. Sad part is I'm looking at buying a custom ordering a '15 Acadia Denali for my wife later this year... I ask for punishment in life I guess. I have just over 13k on the clock since August of this year (yes I drive a lot) and other than the gas pedal, frame rust and the 4cyl exhaust squeak I'm real happy with it. I've had it off-road on my job sites quite a bit. lots of hwy and city driving. Really like the truck. no vibes either. But I'm probly going to let 2 free oil change I have left go and do them myself.... last time they couldn't understand I wanted a tire rotation per the manual. And I paint marked the tires for them.

Maybe I missed it, but has anyone ask their dealership to fix this? considering what we paid it should be on them.

I must be missing something. I got under my dash and looked at the pedal assembly. There does appear to be some looseness side to side in the assembly and a lot of flex when you PULL on the gas pedal, but when pressing the gas pedal, there's very little flex in mine. I have not put a shim in to see if there's any real world difference but frankly, I just don't see how it would help, at least in my case.

 

I see two bolts, one lower and to the right, one higher and more left. I assume from the pictures that the shim is going under the bracket near the lower bolt, correct?
