Why do automobile manufacturers issue part supersedures?

Where is it written a consumer must wait for a component, known to Manufacturer as detective, to fail before the warranty will be honored?

An inquiring mind wants to know.

A part can supersede from multiple factors.

One manufacturer stop producing for company

A part is improved in design

Old part has high failure rate

Different color

Different style

Different country

A part such as a roof rack comes assembled more or less complete

A part no longer is available new/ only re manufactured

There could be more but...you get the drift.

Car Manufacturers never admit they are wrong or at fault unless the NTSB forces them to. Then it becomes a recall "Special Service Campaign" or "SSC" If they see a trend of failure then it becomes a Technical Service Bulletin "TSB" but only replace actual failures hoping the warranty runs out on the others. Best thing is to find out what fails and why and then help it fail yourself.

An improved design doesn't mean the previous part was defective. In my experience, new PN's are frequently because of a different manufacturer.

You'd be in a constant state of repair if you changed every single PN that was superseded as it came out.

With all respect, not interested replacing "Every single PN that was superceded", only emission components presently known defective or improved, and only during the period of all applicable emission warranties.

For instance Bosch supplied Ignition Coils for a car. Then Denso offered a better deal for replacement parts. Both work just fine. But Denso is the only brand available. one of he suffix numbers will be different

Nothing and nobody is keeping you from replacing those parts.
But you really cannot expect a manufacturer to pay for it, for a part that functions well. Nor can you expect the manufacturer to replace parts past the warranty period. Stop trying to justify your desire for free stuff.

Yes, I grasp the concept. Again, I am only interested in emission control component presently known to manufacturer as defective. For example, DPF bracket, DEF pressure delivery line, NOx sensors, etc. all known to fail at some point.

Bob you remember seeing in the aircraft manuals the statement

"when exhausted use" and then about 5 supersedure's

Most frustrating were blueprints with 50-plus unincorporated change orders.

Well, it’s not defective until it fails.

I have a contractor friend with a 2010 w/160,000 that has had none of the common issues. If his rig has seen more than 10 freeway miles a week I’d be shocked. They don’t all sh;t the bed

[Heh. I see our prolific friend has gotten bored with lubrication engineering and has taken up the law.]

The whole issue of "improvements" or "superseded parts" is a total red herring. They have nothing whatsoever to do with either warranties or environmental regulations. As I have said elsewhere, new vehicle warranties protect against the consequences of "defects". In the product liability world, this term has a specific meaning, namely "[A] defective product is one that cannot be used for the purposes intended or is made dangerous as a result of a flaw or imperfection.
https://legal-dictionary.thefreedictionary.com/defect
The term is well-defined--guys on the Internet don't get to decide what it means.

The same term and underlying concept is routinely employed in the regulations that require extended warranties on emissions components. For example, all of the California warranty regulations on emissions devices are written around the term "defect" or "defective":
https://govt.westlaw.com/calregs/Do...Type=CategoryPageItem&contextData=(sc.Default)

Since this is not a defined term in these regulations, the standard legal definition applies. In other words, your emissions warranties apply to devices that cannot be used for the purposes intended or are made dangerous as a result of a flaw or imperfection. The fact that a given part may have been superseded in no sense in itself meets this criterion.
