Rockstar looking into fix for disappearing cars in GTA 5
Apparently there's a glitch in Grand Theft Auto 5 that results in your car disappearing. Several players have reported vehicles mysteriously disappearing from their garage, or flat out losing upgrades following completed missions.
"I upgraded my car and then completed a mission, and now my car is gone," one user noted. Another added, "I've lost some of my upgrades after completing some missions and then checking my garage." Neither revealed which system they've experienced the glitch on.
Rockstar is aware of the issue and is "looking into" a fix. Unfortunately, the developers have yet to come up with a workaround to recover a car if missing (but you can share your ideas in the comments below). The most recent update from Rockstar notes that the issue "may occur if you drive another character's personal vehicle."
Again, the developer is looking into a fix to prevent this from occurring in the future, but so far there's nothing yet. I've yet to experience the issue (Xbox 360 version), but let us know if you are suffering from the glitch.
