Understanding the Impact of Monsoon on Your Car's Electrical System

As soon as the first rains give us the sweet relief from the sweltering heat, people often hit the roads to travel to hill stations. While we go on road trips to see waterfalls during weekends, our weekdays are filled with countless hours of being stuck in traffic and waterlogged roads. Imagine the impact that has on our cars.

In a country where monsoon brings extremely rampant torrential rains, it is natural that your car and its systems will be impacted. While everyday cars are designed to withstand various weather conditions but extended exposure to moisture and water can lead to several issues that can make driving your car unsafe:

  • Water ingress and leakage
    Constant exposure to moisture, rainwater and floodwater can lead to water entering into the car. Thus parts that are not water resistant can significantly suffer from the same. If water enters the engine bay, interior compartments and other sensitive areas can lead to potential damage to sensitive electronic components.
  • Corrosion and Oxidation
    The presence of moisture or water can become a catalyst for the corrosion process. Considering most of the components of a car are made of metal, corroded parts like wires and connectors can cause poor electrical conductivity. This may lead to malfunctions or even failures of various car electrical systems.
  • Short Circuits
    Water collection, or even moisture, can lead electrical components to short circuit. Car's essential systems, like engine control module, sensors, ignition system and lighting system, can be affected. This can lead to sudden malfunctions that range from minor inconveniences to serious safety hazards.
  • Malfunctioning Sensors
    Today, several modern cars rely on sensors to monitor various parameters and provide inputs regarding the car's systems. Any water exposure, be it moisture or water leakage, can disrupt the functions of sensors such as the engine management system, lock-window control system, anti-lock braking system, and traction control, amongst others.
  • Ignition Issues
    Water or moisture in the ignition system can cause difficulties in starting the engine. Wet spark plugs, ignition coils and other ignition components can lead to reduced engine performance and result in poor fuel efficiency.
  • Battery Problems
    Prolonged exposure to moisture can corrode car’s battery terminals which over time reduces the battery's ability to deliver uninterrupted power. This can result in starting issues and overall electrical system instability.
  • Lags in Infotainment and Electronics
    Prolonged exposure to moisture can damage the car's infotainment system and its dashboards too. Additionally, touchscreen, certain buttons and other electronic components might malfunction or become unresponsive altogether.
  • Flickering and Diminished lights
    As moisture seeps into the fixtures of exterior lights such as headlights, tail lights and indicator lights-- this can not only lead to lesser visibility due to ineffectiveness but also pose a safety hazard.
  • Fuse and Relay issues
    Water seepage or even prolonged moisture can lead to corrosion on fuses and relays which can potentially cause them to fail. Additionally, this can lead to the failure or inability of various electrical systems to work to the fullest of their abilities.
  • Brake and ABS System issues
    Water seepage into the brakes' system can lead to reduced performance or even temporary loss of braking ability. The Anti-Lock Braking System (ABS) may also be compromised if its sensors and control unit have prolonged moisture exposure.

Now that you know the effects of monsoons on the car's electrical system, here are a few ways to reduce the impact of monsoons on your car’s maintenance:

  • Regular Maintenance: Take your car for the recommended services to keep a check on its electrical components. Ensure that the car's components, especially its brake system, battery terminals, connectors, and wiring, are in a good condition.
  • Waterproofing: Applying waterproof electric tape or waterproof sealants to vulnerable electrical connections can help prevent moisture from causing corrosion.
  • Responsible parking: Whenever possible, park your car in a covered area or use a car cover to shield it from the onslaught of heavy rains, leaves and other debris.
  • Avoid waterlogged areas: During monsoons, try not driving on waterlogged roads as you know water can damage the engine and electrical systems. If you must drive through water, do so cautiously and at a slow speed.
