engine failure GLB35
No engine production numbers or time window is known. The M274/264/254 and variants are all related and all can have major failures.
Owning one does not guarantee failure will happen, but I would not own these engines and would dump a vehicle with one. Unless it’s a leased disposable appliance, in which case the only cost to you is your time to deal with the inconvenience.
M264
M254
are successor four cylinder MB engines, with 2.0 liter displacement, turbocharging and direct injection. All are related and all have demonstrated major problems on multiple vehicle platforms.
There are smaller displacement variants of these engines in RoW markets. Multiple vehicle platforms and markets use the wide number of variants. There are east-west transverse and north-south longitudinal variants.
GLB, GLC, GLE and E-class are the most common users of these engines in the N. American market.
Summary: stay away from MB four bangers.

This might help (for USA markets, did not include Europe and Asia because of the abundance of models including but not limited to C 180, C 200, E 200, and the plug-in hybrid models too):
These vehicles (might not had listed all but just from the top of my head) are equipped with
M274: 2017(or was it 2016? anyways if the 2016 E was a W212 then it began in 2017 for the USA market)-2018 W213 E 300, 2015-2018 A/S/C/W205 300, 2016-2019 GLC 300
M264: Facelift W205 (2019-2021 C 300) 2019-2022 W213 E 350, 2019-2024 GLE 350 (although the 2024 V167 GLE 350 has the 48V mild hybrid system now) 2020-2022 X253 GLC 300
M254: All-new C-Class, W206 2022 C 300... as well as on all new GLC X254 2023 GLC 300.

With Porsche imo you need to know what you want and the price you want to pay for it. Then go and do the deal. For a Macan I wouldn’t expect a dealer to handhold the customer’s hand through the process of choosing options, colors etc and doing extensive test drives. There are always exceptions but the rule is more like the above.
Similar problem with MB and the A- and B- cars. The customer demographic is too disparate for one product lineup and one dealer network. A- cars are being discontinued in the US market. The GLB I could see taking over from GLC because the GLB has three rows and is made in Mexico, cheaper for MB than the overseas produced GLC. This would mean discontinuing the GLC in the US market.

You did mention they might want to replace GLC with GLB and discontinue you for MBUSA market? Reason why I asked is because, isn't GLC their best seller, why would they want to discontinue it in that case? Although I think I misunderstood you.
