SIBU: The majority of vehicle fires stem from aftermarket electrical modifications rather than engine malfunctions, said Sarawak Fire and Rescue Department director Jamri Masran.
Speaking at a Hari Raya gathering held at the Sungai Merah Fire Station on Monday (Apr 7), Jamri said such incidents typically begin when car owners modify or upgrade their vehicle’s original wiring, often for accessories like upgraded audio systems.
“It all starts with the factory wiring. Then, people go to shops to change or enhance it, usually for things like radios, and that’s when problems begin,” he said.
He explained that the danger lies in electrical overloading, comparing it to household scenarios where plugging in too many appliances causes circuits to trip.
“At home, electricity is alternating current (AC), but in vehicles, it’s direct current (DC), which generates much higher temperatures and faster current flow. This increases the risk of overheating and fire,” he added.
Jamri stressed that based on investigations and available data, most vehicle fires are electrical in nature.
“Engine-related fires do happen, but they’re relatively rare,” he noted, although he declined to provide specific figures on cases involving wiring modifications.
He urged vehicle owners to avoid tampering with or modifying their car’s electrical system.
“If it’s absolutely necessary, go through the vehicle manufacturer. But ideally, keep everything in its original condition,” he advised.
Jamri also reminded the public that modifications could void manufacturer warranties.
“When you modify the electrical parts and then try to file a claim, the manufacturer usually won’t entertain it. You’ve altered the specifications, and that carries consequences,” he said.
He added that modifying a car’s electrical system often means adding new components while retaining the original fuse, which may not be rated to handle the increased load.
“This mismatch can easily lead to overheating and fire,” he warned.
On the subject of engine fires, Jamri advised vehicle owners to ensure their cars are regularly serviced, especially with regard to engine oil and related components.
