Rattling noise coming from underneath new Explorer ST!
- Thread starter Medotechinc
- Start date
Having the same noise issue over rough surface. Sounds like ball joints, wheel bearings, motor mounts or something significant. I have tightened the fastners on all the "Tupperware" air deflectors underneath and dealer tells me they can't find anything. Sounds like a worn out old truck with 20000 kms (15000 miles). Anyone have any major work needed under the vehicle?

Haven’t heard any unusual noises yet. But, I did discover a surplus airbag dash panel (the one that goes at the edge of the dash, facing the front passenger door). It was in the compartment beside the spare tire.
If they really operate the factory with JIT parts, one Explorer might not have gotten shipped that day.

Thanks for update Medotechinc. I'm reading many dealer responses that Ford says this is normal thumping over rough surface at slow speeds. Not acceptable answer! A $65,000-$70,000 new vehicle should not sound like a worn out old truck on the front end. Where is Ford? We want to know what is causing this and how to fix it. At least acknowledge what is causing it. We and the dealers are spending way too much time doing the same diagnostics when Ford knows what it is and chooses to not share that information.

Isn't that interesting. Not sure how that gets rid of the thumping noise that sounds like suspension but this change you made obviously has made a difference. Anybody else experience this positive change when going to small tires? Since we're left to figure this out for ourselves all information is helpful. Thanks for comment PP.

Ya this is what I posted before on another thread the fact that it feels like we are on our own with a lot of the problems we experience with this ST.
Not sure if its like that with other brands of cars and their customer service or if its just simply finding the right dealership idk.
One thing I'm sure everyone is grateful for is a forum like this one where people help one another out which I know has gone a long way for me!

I admit that I am old school and not always the early adopter though I am at times too. I simply don't like the idea of foam in the tires. Having said that, as I understand it these tires can be repaired using approved conventional methods once the foam is removed around the patch area. You are limited in that you shouldn't make these repairs using an external plug but the truth is that was never the best method for a repair anyway.
Man....
2021 Explorer ST build date 6/21 and purchased on 7/21 so it JUST landed at the dealer. Had to drive 2 and a half hours one way to pick it up.
I have had this exact experience on our brand new ST for the last 2 months of ownership.
The rattling coming from the bottom back passenger area is so bad, me and my wife hope that whatever it is falls off as a joke. Took it to a muffler shop a couple weeks ago and they put it on a lift to see whats going on. It seems like every inch of heat shielding is hitting the body as there is not any buffer installed between the heat shielding and the body. Also there is a clunking noise when I put it in reverse coming from the back passenger suspension area. Both back windows sound like theyre being crushed by the motors and when the come down, it sounds like it is pulling them out the body of the car. Drivers side window auto up and down doesn't work all the time. If you turn the car off and sit in it for 10 minutes, you can hear all this ish happening and to my knowledge ford says that it is circuits closing but whatever. Also during that process, the brake pedal when you try to start it will fall to the floor and the car won't start. You have to push it again and the start button to get it going. Transmission wouldn't accelerate when getting on freeway also throws you forward with shift shock on downshifts in Sport mode. The rpms went up and the car kept rolling at the same speed and of course it throws zero codes. Oh i forgot to mention that the muffler guy said that it seems like my drivers side muffler is bad already.
The best part of all this you ask?
There is no ford dealer that can look at my car within 100 miles (i called every single one) until December 27th.
I was having a convo with the muffler shop owner and another guy was listening and told me that i got a Monday car off the line. I asked him what that meant and he said you got the car built by the people that were getting drunk and high all weekend and are recovering on Monday.
Safe to say im pissed on a 60k car we have to deal with this.
Sorry bout the long post but ive been lurking this forum ever since i got the car and finally had to share my experience.

I have an absolutely ridiculous rattle from under the car. It started back over the summer. Someone else posted about it (might have been in this thread?) as well. It turns out for them it was one of the flex pipes. The mechanic at the dealership went on a drive with me so he could hear it, he also owns an ST, which was cool. It was fixed, and that was it. Until a few months later when it started again. Not only am I hearing a rattle at speed 35 and under, which I find to be humiliating on a 60k car driving around in a city where I am sure everyone else can hear it, because I hear it echoing off of the cars parked on the street, but I am also experiencing a resonating shudder when coasting / decelerating down through 40. One of these days Ill take it back to the dealership.

The amount of flaws especially noises, rattles and vibrations both inside and out are unacceptable, I agree. The good news is most non-enthusiasts don't know the ST MSRP is over $60K. All they see is a Ford Explorer with blacked out trim. The average person wouldn't know the difference between an ST and ST-line.

Took the car to the dealership yesterday, finally. They just called me and said that the rattling and resonation is coming from the same place: The flex pipe they previously clamped to reduce the rattling is now "disintegrating" and needs to be completely replaced.
So, today's lesson: The flex pipes used in at least early-mid production 2020 STs are garbage.
