- Your catalytic converter is destructive or going destructive. The catalytic converter is a part of your 2021 Jeep Grand Cherokee’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 Bill Estes Chrysler Jeep Dodge Ram offers a complimentary multi-point inspection with every Jeep service. If you have an issue with your catalytic converter and don’t get it repaired, your 2021 Jeep Grand Cherokee 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 back-up problems from overheating.
- Your O2 Sensor (Oxygen Sensor) needs to be changed. The Oxygen sensor, noted as the O2 sensor, measures the fee of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your car will be less judicious 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 2021 Jeep Grand Cherokee’s spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to imply the right mixture of air and fuel that enters the cylinders in your engine. A destructive O2 sensor can also cause a car to fail an emissions test.

If your spark plugs or spark plug wires are destructive or classic, you will experience low 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, best to more pricey repairs.
- Your 2021 Jeep Grand Cherokee has a vacuum leak. Every Jeep Grand Cherokee has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower detrimental 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 imposing heat or extreme cold.
- Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Jeep Grand Cherokee is what determines how much fuel is needed to run your engine efficiently by measuring the fee of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to considerable changes, like altitude. If your Jeep Grand Cherokee is having trouble starting, idling rough or has a swift change in the position of the throttle pedal, this could be a sign of a destructive mass airflow sensor.
- Issues with any aftermarket items. An aftermarket alarm, exhaust or back-up item can wreak havoc on your 2021 Jeep Grand Cherokee if it’s not installed properly. These aftermarket parts and accessories can jettison the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound conscious, bring your Grand Cherokee to Jeep and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren’t causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get low work and damage caused by low installation work corrected.
- One of the most natural and frequent cause is that your 2021 Jeep Grand Cherokee gas cap is loose, damaged or missing. The gas cap for your 2021 Jeep Grand Cherokee 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 destructive fuel cap? If your gas cap is classic 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 pricey. If your check engine light turns on immediately after you put gas in your 2021 Jeep Grand Cherokee, first thing you should check is to make positive the cap isn’t loose — or that it’s still on your car’s roof or at the fuel pump.
- The battery is low or dead. The battery in your 2021 Jeep Grand Cherokee is every exceptional. 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 certainly require maintenance.
