Rodent Damage Repair at Jefferson Auto Service

If your check engine light came on out of nowhere—or your vehicle’s electrical system is acting strange—it could be more than a mechanical issue. Squirrels, mice, and rats can cause serious damage under the hood. At Jefferson Auto Service, our auto mechanic team offers specialized auto repair for rodent damage in Harrison Township, Clinton Township, and Romeo. From chewed wiring to engine bay nests, we’ve seen it all—and we know how to fix it.

Soy-Based Wiring + Cold Weather = Rodent Hotel

Modern vehicle wiring uses eco-friendly, soy-based insulation—which rodents love to chew on. Combine that with a warm engine bay in the colder months, and you’ve got the perfect place for a mouse or squirrel to nest, gnaw, and wreak havoc on your electrical system.


Common signs of rodent damage include:


  • Random warning lights (especially “check engine”)
  • Electrical shorts or intermittent issues
  • Strange smells from nests or urine
  • Wires visibly chewed or frayed
  • Engine misfires or stalling


At Jefferson Auto Service, we perform thorough inspections and Digital Vehicle Inspections (DVIs) to find and document the damage. We repair or replace chewed wiring, clean out debris, and make sure your vehicle is fully functional and rodent-free.
