I do not experience any overheating problems with my a119Pro however I do have a lot of the features turned off such as LDWS, FCWS, GPS and Parking Mode. Here is a video
of a mod performed on an a119s to help dissipate heat build up. I'm assuming the a119pro may be similar and really don't know if the mod actually works or if the intent of the tape blocking the vents is intentional to prevent heat from getting into that section? Perhaps someone out there performed this mod and can comment.
