Hello, I was wondering if I could switch from a 185 60 14 to a 185 65 14 tire on my aveo without having any issues?

That depends on what you mean by issues ?

Going to the 65 will increase the overall Tire Diameter about 3/4", which will equate to a speed increase of about 2 mph over what your Speedometer is reading, and you should notice some reduction in Braking and Power.

You will also gain just under 1" in tread width (to 6.5") which will equate to less "crispness" in control unless you are mounting them on like width Rims. (do you know what the width of the Rims are that you'll be mounting them on ?)

And IMHO, as far as any "scrubbing", I don't think that you'll have a problem with that issue.

I believe it's a 14x6

Well, if it is a 6" wide rim, that is within a reasonable fit, so the (crispness) won't be effected all that much. Tires perform their best, when the Sidewalls are straight up and down. Several other negative factors come into play when they aren't as well.

All things considered, I'd say go for it.

Keep in mind, that all new tires need a break in period.
That's usually about 500 miles.
During that period, you should keep them aired to a higher pressure.
That's usually within two (2) Lbs of the Maximum Cold Inflation Pressure.
That number is found stamped on the Sidewall of the Tire.

I run my Tires aired to that higher pressure throughout the year.
Gas mileage and several other performance features are enhanced at that level.

About the Maximum Cold Inflation Pressure...
The PSI (Pounds per Square Inch) number stamped on the Sidewall of any tire, is the Manufacturers guarantee that it can be operated safely at that pressure, for the life of the Tire. Airing your tires up to/at that pressure, is NOT considered over inflation.
