Traffic issues: grid lock for no reason? traffic issues

While I can't exactly point out what you are calling a gridlock here, you have pedestrians crossing at your top roundabout which does make vehicles stop in order to allow them to pass.
 
I also have a problem with pedestrians in one of my cities. For what I have seen, cims walk al lot, and this means having lots of pedestrians, and pedestrians cause a lot of traffic issues, specifically in roundabouts. If you have traffic lights you can use the mod to customize traffic lights, don’t remember the name, and put an exclusive pedestrian phase, which helps greatly.
 
Yeah, the cars will stop completely random, for no reason in roundabouts even with no pedestrians in sight or any other cars nearby, it's interesting.
It's not too frequent but frequent enough that you will spot them if you watch a roundabout for a few minutes. It's as if their pathfinding just decided to stop working in the middle of their journey and the simulation will then despawn them.

I would bet there has been countless of bug reports posted already over the year by now. Maybe one day it can be fixed.

Roundabouts dont work well. They need some fixing from the developers
More like, roundabouts aren't supposed to be used for medium to high levels of traffic throughput at intersections. Instead, they are used for low traffic intersections.

The game is trying to teach you not every kind of intersections can be done with roundabouts. Sometimes, traffic lights are better than roundabouts, and this is one of those cases.

While it’s true that roundabouts are not a panacea for every traffic problem, there is a bug with multi-lane roundabouts that causes vehicles to freeze within the roundabout and never exit, even if the road ahead of them is clear.

Totally, it's absurd. Even if you move the vehicle manually with a mod, it go back to the stuck position again

I will forward this to the developers to take a look.
After checking the clip it reminded be one particular bug report. It might be the root cause of this issue and probably a lot of other where roundabouts are involved.
It might be worth bumping up the priority, or something, since it might resolve a lot of other strange traffic jam issues.

this is another. I do not know if this is a bug or something else like scared of ghosts type video..

I have come across this issue very often and after a lot of observation I accidentally noticed it's actually the emergency vehicles that cause this. Any traffic that crosses the path of an emergency vehicle stops and gives way to it. It is a good gameplay feature, however it sometimes takes place when the emergency vehicle is not the first in the line waiting to cross, just like in the clip above. In this case, the vehicles crossing the emergency vehicles' path either stops and then goes on or stays put forever. This is more prevalent in roundabouts, where you have extra priority rules in place.

So, in the clip here, the ambulance wants to use the outer lane of the roundabout (see the vehicles stuck right before than lane?) and, at the same time, the car in front of the ambulance gives way to the oncoming traffic from the roundabout, leading to gridlock.

Hope this gives a little insight on the issue.
