• Issues with all aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your 2012 Hyundai Elantra if it’s not installed perfectly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prohibit the car from starting. If these issues sound receptive, bring your Elantra to Hyundai and have our company of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing all issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a microscopic bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• New Spark Plugs or Plug Wires are essential for your 2012 Hyundai Elantra. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your car. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or departed, you will experience 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, main to more expensive repairs.
• Your 2012 Hyundai Elantra has a vacuum leak. Every Hyundai Elantra has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower down harmful 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, especially if they’re exposed to adequate heat or extreme freezing.
• One of the most common and innumerable cause is that your 2012 Hyundai Elantra gas cap is loose, damaged or missing. The gas cap for your 2012 Hyundai Elantra serves multiple purposes. It prevents 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 bad fuel cap? If your gas cap is departed or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on immediately after you put gas in your 2012 Hyundai Elantra, first thing you should check is to make bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Hyundai Elantra’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by neglected maintenance, which is why Courtesy Hyundai of Tampa offers a complimentary multi-point inspection with every Hyundai service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 Hyundai Elantra will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause alternative problems from overheating.
• The battery is low or dead. The battery in your 2012 Hyundai Elantra is every decisive. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did various decades ago, and they don't genuinely require maintenance. The estimate of a new one depends on the type of Hyundai you drive, but check our current service coupons and specials.
• Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Hyundai Elantra is what determines how much fuel is essential to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to cognizant changes, like altitude. If your Hyundai Elantra is having trouble starting, idling rough or has a speedy change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
• Your O2 Sensor (Oxygen Sensor) needs to be changed. 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 faster and your car will be less productive 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 damage to your catalytic converter and your 2012 Hyundai Elantra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
