Most Common Jeep 2.4 Engine Problems
Although it’s an old engine, it has a reputation for a reason; hardiness. Even after years, it doesn’t break down.
Even so, a few issues may rear their ugly heads. Most of them are minor, but some are significant issues that may be critical for you, but don’t worry! We’ll help you solve them!
High Oil Consumption
The most common issue owners face worldwide is this engine’s high oil consumption.
With low oil prices, it wasn’t this big of a deal back then. It has become a massive concern for consumers, with them through the roof now.

These issues cause sudden shutdowns and stoppages, which can be disastrous!

Vibrations and Rattling
Another common complaint from Jeep 2.4L owners is that it vibrates and shakes.

The issue is that when the Jeep 2.4L engine runs for a long time, it gets heated, raising many issues.
Another issue is the “Crank Walk.” It occurs when the crankshaft violently moves back and forth, and it can cause a lot of damage to the engine.
Vibrations can arise from the following underlying issues:
- Timing chain issues.
- Problems with the fuel intake.

The reason is that this engine is unstable. Sometimes, under heavy pressure and exertion, the Jeep throws out excess air outside, causing many emissions.
Not only that, the emissions are increased further due to the large amount of oil it consumes, about a quart every 1000 miles!
Another essential factor when buying a Jeep is passenger comfort. As you may have to travel long distances and on rough terrain, it’s better if your passenger is comfy.
The headrests in the Jeep 2.4L are super low, and this leads to tall passengers having to bend slightly to rest their heads on them.
