Loud Rattling Noise Upon Cold Engine Start

[1991 sploder]

That certainly leaves the question why not more members are experiencing this and why Ford would even approve a buy back on something that is 'normal'. It also appears that this issue only pops up on the ST and not on the other models. So far, I haven't seen any reports about this issue on Aviators.

I know for sure that I won't accept a $60K vehicle that wakes up the entire neighborhood and sounds like a 50 year old diesel.

Ford cannot afford to have any fatal flaws in its sport utility cornerstone - Explorer. What is otherwise an excellent entry is flawed by a noisy engine.

Hmm seems like IT IS all models!

Lol 50 year old diesel

As far as I know, my Aviator has the same engine and is perfectly quiet on start-up.

The OP and others here have the ST which has the same motor as the Lincoln. Aviator.

Mine is quite at startup. The article that you linked said the 2.3L is loud on accelerating, not on startup. 2 different things.

Some 2020 Explorer/Aviator vehicles may exhibit a rattle type noise originating from the exhaust flexible pipe. This may be due to the natural harmonic frequency of the pipe. To correct the condition, follow the Service Procedure to install a worm gear clamp over the exhaust flexible pipe.

Guessing that's ur issue.

That is a TSB issued in June. Exhaust Rattle | Ford

But I doubt that is the issue as it relates to an exhaust noise, not noise coming from the engine.

Yea get a stethoscope lmk what u find

For this exhaust rattle issue, the TSB is dated 29 June 2020 so does that mean that it is applicable only to vehicles manufactured before that date?

I don't think they would take the vehicle apart if they think it's normal. I showed that video to the guys at the service department and as soon as they heard it, they confirmed something was wrong.

Now, if it would indeed be normal after 5k miles, how many cases/complaints about this issue would we have seen by now? Are you suggesting that owners would not be reporting this if their vehicle which was totally fine at startup when they bought it all of a sudden made this noise? It is so loud, no way you could miss that. If this would be affecting every Explorer (or even just the STs and all Aviators), the internet would be full of reports about it.

And look what the user WILMAC posted at the beginning of this thread. Would Ford do a buy back if this is normal? I doubt it...

Take a video or something

He's to busy with his stethoscope to read and listen to what has been posted. 1991 sploder do you have any experience with a 2020 Explorer?

Yeah, I agree, if this just suddenly develops and it is an abnormal rattle, it should Not be normal. I can understand and one second tappet kind of noise just upon starting but a long time rattle at startup on a gasoline engine that too suddenly developing after few thousand miles should Not be normal.
