Insulation question new build

Could of questions about insulation:

1 ) I have R6 ceiling insulation batts all over, and R2.5 to the external walls EXCEPT my garage external walls

They are R2.0, will that make a difference even if it is a garage?

2) The corner space between two walls towards the brick side does not have any insulation, will that be a problem?

Unless you insulate your garage door that is where the heat is.

Our triple garage is under the main roof with R6.0 batts there too and it gets hot. Your doors "attract" that heat and it goes in there.

I have installed some small windows in the garage plus an automatic extraction fan which draws the heat out and it works a treat. Dropped temp by almist 10 deg the other day when it was 40 outside.
