Do I *Really* have to seed my Car?

So I recently downloaded a 2006 Toyota Camry and while I'm happy with it, I have noticed occasional issues like blinkers not working, Radio blasting static, and even occasional crashes (only like three people were hurt so far chill)

These only occur whenever I'm seeding, so do I really have to seed my car? The Camry is a popular model to download so I can't imagine there is a big lack of seeders?
