I bought a MacBook Pro two days ago and when I was using it for the first time I noticed that when it drops below 40% (20%-40%) it shuts down with no warning and it's impossible to turn it back on unless I plug in the power cable. I thought it must be a hardware issue so I got it replaced for a new one. I set up my new computer and I found out that it had the same issue.
I tried resetting the System Management Controller (SMC) as per Apple's instructions at: https://support.apple.com/en-gb/HT201295
Unfortunately, this didn't resolve the issue.
At this point I think it would be stupid to buy a third MacBook Pro just to find out that it's not working again.
Has anyone come across any information that indicates this is a known issue?
For the record, here is my battery information:
CHARGE INFORMATION:
Charge Remaining (mAh): 5107
Fully Charged: No(its 100%)
Charging: Yes
Full Charge Capacity (mAh): 5159
HEALTH INFORMATION:
Cycle Count: 3
Condition: Normal(1 day old battery)
Battery Installed: Yes
Amperage (mA): 2439
Voltage (mV): 12516

At this stage it's too early in the product cycle for this model to know if this rates as a known issue for Apple.
However, any product, no matter the type or manufacturer, can have a fault and having bad batches of components is not unheard of. Apple does use warranty extension programs, replacement programs and repair programs if/when it identifies there's a definite issue to address. At this stage though it would be pure speculation, even if a handful of MacBook Pros presented with the same issue.
You indicate you've reset the SMC as per Apple's instructions, but just to be thorough your model MacBook Pro has a T2 chip and you have two options for resetting the SMC (the 2nd to be tried if the first fails).
Resetting the SMC on a 2019 MacBook Pro
Once you've reset the SMC fully charge your MBP and see how you go. If it's still misbehaving, reset the SMC again but with the following steps instead:
Now test your MBP again.
If the above fails, then I'd be talking to Apple Support to explain what's happening. If they can't address the issue then you're entitled to a refund or replacement, but you'll want to get onto it straight away so that a case is logged this early in your ownership.
