Perhaps the most important of these is a fix for a bug which has seen saved cars and upgrades going missing from garages, unfairly depriving characters of both a sexy ride and wasting a few grand of their spent cash. I've been afflicted by this one and it's a giant pain in the ass.
Here’s a list of all the headline fixes, courtesy of Rockstar:
Fix for interface issues when using Internet on the cell phone after completing the game, or during a mission replay
Fix for the Vanilla Unicorn occasionally becoming locked
Fix for issues where the character’s money could drop below zero and become stuck there
Fix for the Epsilon Program missions not progressing properly after delivering some cars
Fix for issue where the Atomic Blimp sometimes does not appear as a phone contact for Collector’s Edition owners
Fix for issues with saved vehicles going missing, or losing their upgrades
Fixes for several map escape and collision issues along with other various bug fixes
The title update was included as part of the download which unlocked Grand Theft Auto Online earlier today.

Rockstar support released a comment about the problem on Monday in which the developer recommended fans avoid using the garages inside the open-world game until a fix can be deployed.
The known bug that has a tendency to delete saved vehicles from garages seems to be triggered by several different things. Rockstar Games’ support stated that these include completing a mission or driving a character’s personal vehicle while controlling one of the game’s other two protagonists.
For the time being, Rockstar Games is suggesting that players avoid storing or withdrawing cars from garages. Additionally, fans should not drive the personal vehicles while on a character who is not the owner. The developer is currently looking into solving the issue, but the actually cause is not known at this time.
