I know there has been multiple threads on this issue but I’m hoping someone has had luck with a resolution.

2023 Tremor. 3.5 Eco. Purchased new with 12 miles on the odometer. Just passed 4,000 miles. Right around the 3500 mile mark I started to notice a vibration felt in the gas pedal. It doesn’t matter what speed or gear I’m in. It happens in both 2WD and 4A. It’s way more pronounced when I get aggressive on the pedal. The vibration is not rough but very high frequency and constant. After driving for more than 20 minutes cruising at highway speeds my right foot feels tingly. It’s clearly not my imagination.

This was not an issue until the 3500 mile mark. Had the tires balanced and wheels aligned….didn’t help. Took it to the dealership. The tech drove it with me and said he noticed a vibration. They kept the truck for 2 days and told me they couldn’t find any problems and the vibration is “normal”. I drove my neighbor’s 2023 F150 and there is zero vibration in his.

It’s obvious the dealership is going to continue to tell me it’s normal until something fails or breaks.

Anyone have this issue?

 

You might want to post in the 21 and up, plus share specifics on drivetrain.

 

My 22 has a similar feel. I tightened the fiber insulation on the firewall and it seemed to help.
