Jeep 2.4 engine, also known as the 2.4 world engine has been used in four Jeep models over the years. Like any other engine, it does show issues after a certain amount of time. This is natural. But there are some problems in the 2.4 engine that have persisted commonly for many Jeep users till now.
So logically, every consumer would want to know the most common Jeep 2.4 engine problems. The most frequent one is aggressive oil consumption. Besides that; transmission problems, abrupt shaking, and excessive outflow are the most commonly faced issues in the 2.4 engine.
Properly inspecting your Jeep after every long journey or mileage can help you tackle these issues. But why is it so reliable even after such common problems? Keep reading to know more.
There are two types of 2.4 engines:
- World Gasoline Engine
- Tigershark engine
Here is a chart showing all the Jeep cars with 2.4 engines:

The 2.4 Jeep engine can cause different types of problems. This might vary from model to model. However, here we will be discussing the 4 common ones that most Jeep users complain about across all the models.
1. Aggressive Oil Abuse
The 2.4 engine uses up all the oil pretty quickly. It burns the oil super fast, even in moderate usage. So it’s possible that you might be left off oilless in the mid highway without any prior warning!
It’s better to test the oil usage every once in a while to be more sure. If anything seems suspicious, then it’s better to take professional support.
However, in this video, you can see that a certain software update in the 2.4l engine Jeep Cherokee was able to solve the issue.
2. Transmission Mismanagement
There are a lot of things that need to be managed properly in the transmission section of a vehicle. And the engine puts them all together in the final phase.
These include shifting the speed from a certain level, changing from forward to reverse gear, etc. However, if the engine can’t handle these operations, it causes serious abruptions.
In a 2.4 engine, this is another problem that causes wire disruption inside the engine. The car suddenly stops midway when such a thing happens. It requires a restart to solve. But the problem might not disappear easily.
An engine can experience four types of vibrations:
- Vibration when put in gear
- Vibration when starts
- Vibration after driving for a while
- Vibration while idling
The shaking problem persists in a 2.4 Jeep engine too. This engine can’t cope with the exhaust very well. As a result, the byproduct gases of the fuel intake system cause the engine to heat up pretty quickly.
Whenever this happens, the passengers experience absurd vibrations, mostly after driving for a while. This is an alarming situation because it might also indicate a problem in one of these parts:
- Spark plug
- Ignition switch
- Engine mounts
- Fuel and air filters
Too much air outflow through the exhaust pipe has been another common issue in the 2.4 engines. Put simply, you can’t rely on the actual capacity of this engine.
At times, the exhaustion increases trigonometrically. That’s because an unhealthy explosion takes place inside the engine. Hence, the outflow disrupts not only the transmission but also the control.
The amount of oil consumed per 1000 miles is one-fourth of a gallon for this car. That’s quite a big spending we are talking about here. So you can’t have any extra exhaustion that can add to that.
The above-discussed ones are the most frequent among all the users of the Jeep. However, there are some less common problems which were faced by a number of consumers. Those are:
- Occasionally, the engine area may emit a buzzing sound due to a damaged exhaust system.
- Issues related to vehicle performance caused by malfunctioning throttle position sensors.
- A worn gas cap caused the error code of p0456 to pop up in some of the Jeep.
Most of the time proper inspection can help you get the most out of your Jeep 2.4 engine. This can also reduce the commonly faced problems to a minimum.
Here are a few tips on inspection:
- Consider changing the oil after every 7.5k miles of the journey.
- If that’s not possible, never let the limit cross 10k.
- If you have driven 20k miles, give a thorough check-up of the CV joints, air filter, and suspension components in front.
- If you have driven 30k, then it’s time to say goodbye to the air filters immediately.
- And finally, if you have driven 60k miles, then change the ignition system including spark plugs and wires because they would be worn out by then.
Although there are some hiccups, a 2.4 engine is still widely used worldwide. There must be some reliability factors that make people go for it nevertheless. Let’s look at some of them:
- This engine can sustain long drives most of the time
- If you take proper care, then 12k miles at a stretch is a piece of cake for this engine
- Most of the consumers complain about issues after a whooping 120k miles
- The HP is 150, which is terrific compared to its competitors
- This engine is gas-friendly
- The price of this engine is reasonable
- The lightweight of this engine puts less stress on the whole structure of your Jeep
- This engine’s belting is mainly rubber-made, so the camshaft and timing are easily maintained through this
- If any of the components of this engine gets damaged, it’s easy to find mechanics to fix it and the replacement is also quite easy to come by.

Jeep has been using the 2.4 engine for a long time in its models. The reliability and sustainability of this engine have been top-notch. That’s why people frequently make queries regarding this engine. However, common problems such as oil consumption and vibrations remain as hiccups.
It’s a bit strange why the manufacturers still aren’t able to fix these issues for good. Hopefully, they will be able to find permanent fixes in the near future. Till then, this article will help you keep all those issues in check.
