2020 Explorer ST Humming/Rattle When Accelerating

Okay, I just confirmed that the rattling flex pipe issue still exists on 22 model ST's.

There is a TSB for this issue but from what I have heard, it does not work.

Correct, the hose clamp "fix" doesn't work:

But this does:

Going to have Ford do the fix on the second video during my next oil change.

Cool, let us know how it turns out. Did they try the hose clamp thingy first?

I haven't brought up the issue yet so curious to see if they go the worm clamp route first. Hoping I can just talk them into changing out the flex pipes entirely. Also, need to have them check the heat shields as well. Heard some folks on here talking about those coming lose and rattling.

Man, I remember when loose heat shields was something that happened to vehicles with 50-60 thousand miles on them. Not new cars. Lol

Following, as mine has the 'card in the spokes' sound also.

My '21 ST will make the noise accel or decel, partial throttle. I can't tell if it does it all the time with the fake engine noise plumbed in. Seems to get louder if I drive it longer. Not super loud, but annoyingly loud.

Goes in tomorrow for some recall work and see if they can hear this sound.

Don't buy the normal BS from the dealerships. I will miss my 21 ST (Bought in Nov of 20) significantly - but the quality just isn't there IMHO. My problems in the 15 months that I have owned it in order

Defect in the lift gate glass caused cracking - fixed
Transleak - tailshaft seal as well as cooler seal - fixed
Sync problems - rear camera - fixed
Sync problems freezing - not fixed
Sync app no pairing anymore - can't reset connectivity - I'm SW engineer(an gearhead) so I know what I am doing - not fixed
Vibration at 60 in the steering wheel and only around that speed - not fixed
Vibration in the vehicle b/w 8-1100 rpm - continue reading

Forgetting sync absolutely sucks - and I could live with the quirks. The vibration issue experience made me pull the buy back trigger.

1. Flex pipe rattling will vibrate the entire exhaust which resonates through the vehicle
2. Tech called ford and said "crank imbalance" and engineering instructed them to replace the long block.
3. New engine put in vehicle - vibrations still exist(shocked I was).
4. Tech called Ford and said when they disconnected exhaust from the cats that vibration stopped(again shocked!).
5. Ford approved replacing from the cats back -2 week wait.
6. New exhaust arrived and tech noticed that there was rod knock in the new long block.
7. Tech inspected the oil and found it to be nice and glittery and the filter looked like a disco ball.
8. Ford said to replace long block (and no to the turbos).

Buyback approved and seems to be going smoothly. Wont get another exploder as tempting as it is -don't feel like paying the 3k difference in MSRP to get back to where I was. 15k MIles

So, push on these guys telling you the issues you have are normal. They are not!!

you ever get this fixed
