Google is your friend. AI Overview A Toyota Prius car alarm going off randomly could be due to several reasons, including a low 12V battery, faulty key fob, or a malfunctioning door switch. Other potential causes include environmental factors, electrical issues, or a faulty alarm system itself. Here's a more detailed look at potential causes and solutions: 1. Low 12V Battery: A low 12V battery can cause electrical problems, including the car alarm going off randomly, according to a Reddit user. Solution: Get the 12V battery checked and replaced if necessary. 2. Faulty Key Fob: A malfunctioning key fob, especially with a low battery, can send incorrect signals, triggering the alarm. Solution: Replace the key fob battery or consider replacing the entire key fob. 3. Faulty Door Switch: A failing door switch can be a common cause, as it signals a forced entry to the alarm system. Solution: Check the door switches, especially the ones near the doors, and consider having them repaired or replaced by a mechanic. 4. Environmental Factors: External factors like wind, rain, or passing vehicles can trigger the alarm, especially if the sensitivity is set too high. Solution: Try parking in a different location to see if the alarm continues to go off. You may also want to adjust the sensitivity level of the alarm. 5. Electrical Issues: A weak battery, faulty alternator, or loose connections can cause the alarm to malfunction. Solution: Have a mechanic check for any electrical faults. 6. Faulty Alarm System: The alarm system itself may be faulty, causing random triggers. Solution: Have a mechanic inspect the alarm system for any wiring or sensor issues. 7.

Trunck not closed all the way. Not placing the spare tire that's compartment correctly causes the deck lid to push up on the rear hatch. The rear hatch will feel like it's closed but it's only at the safety latch. When you go over bumps it rattles triggering weird alarms.
