The outlets shown are 15 Amp maximum and should not be not be powered by the 20 Amp breakers pictured.
No, that's incorrect.
The information from this individual is spot on.
No, it's not spot on. It is false.
If I'm reading this correctly, you are saying this setup as is right now is dangerous? Should I get the landlord involved if that's the case?
No, it's not dangerous, and it is perfectly code-legal.
I believe what AlMason is saying is that there appears to be a mismatch between the outlet and the breaker. this could be a hazard and should be inspected.
No, it's not dangerous, and it is an allowed mismatch by NEC, and no it doesn't need to be inspected.
The fact that a 15 Amp outlet is attached deserves a check, just to be sure, before you pull any serious current.
It doesn't need a check. It's code compliant and standard practice.
Jeez. There are sections of the National Electric Code that talk about branch circuits with multiple outlets on them and which ratings of outlets are allowed to be on them. The main descriptive code section that talks about it is 210.21(B)(3), and then there is a reference table, which is 210.24. It very specifically allows that these household circuits that are 20A, with 20A circuit breakers and wiring are allowed to use a mix of 15 or 20 amp outlet types (5-15 or 5-20).
Here are a few references for this:

In 210.21(B)(3) we now need to deal with which amperage receptacles are permitted on which amperage circuits when using more than a single receptacle. Table 210.21(B)(3) gives us this information, but it can be a little confusing to those who try to apply common sense. The first line is ok: a 15-amp circuit limits us to 15-amp receptacle or lower. However, the second line allows us to install either a 15- or 20-amp receptacles on a 20-amp circuit. This is actually a very common practice for receptacle circuits. Unless specified by a design professional, the 15-amp receptacle commonly gets installed on a 20-amp circuit.
Here is a picture of the 210.24 table although this article is asking about a different question, but you can see it does say 15 or 20 amp outlet types allowed on the 20A circuits:
Why is it OK to use a 50 A receptacle on a 40 A circuit?
OK, now that we've cleared up all of this wrong information about code, let's talk about this, which is relevant:
Also if I can't, for some reason now the UMC shows a blinking red light on the regular 5-15. Before it was working. The outlet is pretty loose, could that be the problem?
Thanks to
@KJD. Loose outlet is definitely not good and should be fixed. That is a pretty common fire danger and is a general thing, not specifically related to car charging. Any kind of outlet that gets used a lot over many years can have the internal "squeezing" springs get worn out and not grip plugs very well. Those loose connections can make a resistive hot spot. So if you find outlets that are loose when you try to plug stuff in, go ahead and replace those outlets.
And blinking red light may be indicating that it can't detect ground. That is something you would need to check on.
