Toyota Sequoia alarm issues possibly linked to electrical problems from windshield replacement and water leakage on Toyota Sequoia

Some Toyota Sequoia owners report experiencing alarm malfunctions potentially linked to electrical issues arising from windshield replacement and water leakage. These problems can stem from water intrusion into the under dash fuse box or worn-out door lock actuators, which may trigger alarm disturbances, particularly after the vehicle has been exposed to moisture. Additionally, faulty components such as the hood switch, 12V battery, key fob, door sensors, or wiring issues can contribute to these alarm problems. Owners have noted alarms going off unexpectedly, especially at night or after rain, often due to imperfect door latching caused by damaged actuators. Repair shops may face challenges in diagnosing these intermittent alarm issues, especially when they do not present themselves during service visits. To mitigate these concerns, it is advisable for owners to inspect for water damage, check the condition of electrical components, and seek professional evaluation from qualified mechanics familiar with Toyota vehicles.
