Short answer: Avoid leaving a vape unattended in a vehicle, especially in direct sunlight or extreme temperatures. Moving it from the dashboard to another compartment does not make a hot car safe storage.

Why location matters
Heat can affect the battery and product condition; cold can also affect performance. Follow the storage range on the manufacturer’s packaging.
What to do after exposure
If the device is swollen, leaking, damaged or unusually hot, do not use or charge it. Seek manufacturer guidance and follow local disposal rules for damaged devices.
For battery precautions, see the FDA battery safety guidance. Follow the instructions for your exact device.
