Fixing Random Alarm Sound from 2011 Toyota Sienna
Last Saturday, the alarm from our 2011 Toyota Sienna went off at 7 pm, 12 am, and 3 am. I lost my sleep and decided to find a fix for it. I searched up YouTube and found this video, which seemed to have similar issue with a 2011 Toyota Sienna. The sensor right underneath the hood latch was clogged up; therefore, it triggered the alarm. The fix was to clean the latch.
- Engine Degreaser: $5
- Brake Cleaner: $5
I cleaned the latch on Sunday morning. The alarm hasn’t gone off since. I hope that did it.
