Ignoring that warning could end up causing major, extensive damage to expensive engine components.

If your spark plugs or spark plug wires are bad or old, you will experience a evident poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more pricey repairs.

If you have an issue with your catalytic converter and don't get it repaired, your 2021 Hyundai Ioniq EV will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other dangerous problems from overheating.

As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Hyundai Ioniq EV is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a important sign of a faulty mass airflow sensor.

It prevents perilous gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a faulty fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more expensive. Luckily, to replace a gas cap isn't pricey.

Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't absolutely require maintenance.

The vacuum system again helps lower adverse emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, exceptionally if they’re exposed to intense heat or extreme cold.
Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more quickly and your car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2021 Hyundai Ioniq EV's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the definitely correct mix of air and fuel that enters the cylinders in your engine. A faulty O2 sensor can again cause a vehicle to fail an emissions test.
