Why Cars Catch Fire: Hidden Risks of After-Market Mods & Missed Services

Introduction

In recent months, reports of cars—whether petrol, diesel, or electric—catching fire have surged across India. While social media often blames “bad luck” or “battery defects,” the truth is usually closer to home. From Wheely Wash’s experience in Lucknow, after-market electrical work and delayed servicing are the leading causes of these dangerous incidents.

1️⃣ After-Market Electrical Modifications: A Silent Fire Starter

Many car owners upgrade their base model with:

• Heavy-bass music systems & woofers

• High-intensity headlamps and ambient lights

• Sirens, hooters, or aftermarket security alarms

While these upgrades look and sound impressive, they often overload the car’s original electrical system.

How It Causes Fire

Cars are designed with a specific battery capacity—say 60 Ah. Adding power-hungry devices forces the alternator and battery to supply more current than they are built for. Overloaded wires and connectors can:

• Overheat

• Melt insulation

• Spark, leading to fire

Wheely Wash Tip: If you must upgrade, choose manufacturer-approved accessories and have them installed by certified technicians who match fuse ratings and wiring gauges.

2️⃣ Skipping Scheduled Service: Hidden Hazards

Routine service isn’t just about oil changes; it keeps your car’s cooling, fuel, and electrical systems in check.

Key Service-Related Risks

• Low or expired coolant → engine overheating → potential engine-bay fire.

• Worn belts or hoses → leaks of fuel or oil onto hot components.

• Neglected battery maintenance → corroded terminals or loose connections sparking under load.

Wheely Wash Tip: Follow your manufacturer’s service interval strictly—especially before summer heat waves or long trips.

3️⃣ Preventive Measures Every Car Owner Should Take

• Avoid unauthorized electrical work: Never compromise on wiring quality.

• Install a car fire extinguisher: A small ABC extinguisher can stop a minor blaze.

• Check fuses: Use the correct amperage; never bypass or up-size a fuse.

• Park smartly: Avoid parking near flammable materials when the engine is hot.

4️⃣ Special Note for EV Owners

Electric vehicles require certified charging equipment and dedicated wiring. Avoid extension cords and always monitor charging for abnormal heat or smell.

Conclusion

Saving a little money on aftermarket upgrades or skipping service might feel convenient, but it risks your car and your life. At Wheely Wash in Lucknow, we see the aftermath of these decisions daily.

Stay stock, stay serviced, stay safe.
