Depends on your battery. If it has a new battery, it should be fine. If it is the original battery (now 4 years old), it may not hold up. You can disconnect the negative battery terminal cable to reduce the chance it will be dead when you return.
This all depends on the battery drain. Does the battery get weak when it sits for days? I would not disconnect the battery as this can cause issues. Try a battery tender to keep the charge up.
If I don't drive my 2015 Sienna for 3-4 months, will the battery be dead when I try to start it?
