My in-laws have the electronic rodent repellers installed in two out of 3 vehicles. They hadn’t gotten around to installing the device into the recently purchased vehicle, a new RAV4. Last week, the service light was on and the dash computer stopped functioning. Took it to the dealer hoping to get it repaired under warranty. Turns out, it was rodent damage totaling $450-ish in chewed up wiring. The tech said the harness was salvageable but the damage wasn’t covered under warranty.
Looked it up to see if there was any precedent regarding the matter. Fairly recently, there was an unsuccessful class-action law suit against Toyota. So, no hope to get it fixed on Toyota’s dime. Despite the ruling in the class action, it’s obvious rodents are attracted to the soy-based wiring insulation.
I was skeptical of the electronic rodent devices. I could always hear the occasional high pitched noise from the devices when visiting my in-laws. I’m 80% convinced they help but 20% skeptical this was just coincidence. I’m going to pass along your glue traps idea.
By the way, my in-law purchased another electronic rodent repeller from the same manufacturer. After installation, I noticed it’s not as loud as the older versions. The pitch might be higher or the volume is lower.
