Malfunction in Opel Zafira

Our Opel Zafira has a malfunction, and we’re not exactly sure what’s causing it; we also had the battery replaced yesterday. We were planning to go to Italy on Sunday, but we’re not sure if we should. Our mechanic says it’s probably okay, but the six of us don’t want to end up stranded on the side of the road. What should we do now, because we made a two hour drive today and after two times restarting the car the malfunction was gone.
