1. Chewing on Wires

Rodents often chew on vehicle wiring, as some manufacturers use soy-based wire insulation that attracts them. This can lead to electrical malfunctions, such as:

• Dashboard warning lights.
• Problems with headlights, blinkers, or brake lights.
• Non-functional power windows or door locks.

2. Damage to Insulation and Hoses

Rodents can chew through:

• Hoses, potentially causing coolant or fluid leaks.
• Engine bay insulation, exposing components to heat or vibration damage.

3. Nest Building

Rodents often build nests in:

• Air filter compartments.
• Engine bays.
• Cabins (under seats or in vents).

4. Contamination

Rodents leave behind urine and feces, which:

• Produce unpleasant odors.
• Introduce potential health risks if airborne contaminants enter the cabin.

5. Impact on Engine Performance

Chewed wires or blocked components can cause:

• Engine misfires.
• Reduced airflow in air intake systems.
• Overheating due to chewed coolant hoses.

6. Physical Damage

In rare cases, rodents can gnaw on soft metals, causing further mechanical issues.

Preventative Measures

• Park in enclosed spaces: Use a garage whenever possible.
• Seal food sources: Don’t store pet food or garbage near parked vehicles.
• Regular inspection: Check under the hood for signs of rodents.
• Use deterrents: Mothballs, peppermint oil, or ultrasonic devices may discourage rodent activity.
• Rodent traps: Use traps near parked vehicles to catch them before they cause damage.

Southern California’s warm winters make year-round vigilance necessary. If you notice signs of rodent activity, it’s best to act quickly to prevent extensive damage.
