A mechanic who brought in one Nissan-pickup at his garage was completely shocked when he saw what was causing a “red light” on the underside of the vehicle.
The event was shared by the workshop Bratz Tire and Auto. They said the owner took the pickup to the repair shop after noticing a mysterious “red light” under the vehicle.
“I started looking around and… Oh! There you are! Yeah, I don’t think that’s an LED,” said the unnamed mechanic as he bent down and realized the exhaust system was hot and glowing red.

More specifically, it appears to be the catalytic converter that is the source of the problem. Although this component is designed to withstand high temperatures as it burns harmful emissions before the exhaust leaves the tailpipe, it should never glow like this.
According to the National Highway Traffic Safety Administration (NHTSA), such problems increase the risk of fires and explosions and should be addressed immediately as soon as the driver becomes aware of the problem.
But what causes this phenomenon? The most common cause is the presence of unburnt fuel in the exhaust system. When fuel that should have been burned in the engine reaches the catalytic converter, it ignites there and raises the temperature dramatically.
This in turn can be caused by defective spark plugs, faulty ignition coils, broken fuel injectors or problems with the oxygen sensors.
Oil burning also contributes to the problem. When piston rings or valve seals are worn, oil can reach the catalytic converter, impair its function and collect heat, which can lead to internal clogging.
In some cases, the catalytic converter itself is simply about to give up or is clogged, which is more common on high mileage vehicles. When exhaust flow is restricted, heat builds up quickly, and the glowing metal becomes the visible symptom of this restriction.
The repair can cost between 1,500 and 3,000 US dollars. However, it is important to emphasize that replacing the catalytic converter without addressing the root cause – such as ignition or fuel supply problems – often leads to recurring failures. Therefore, it is important to evaluate together with your mechanic what is causing the problem before rushing to replace the exhaust system.
