Common Symptoms of Engine Issues
When it comes to engine problems, being aware of the symptoms can save you time and money. Here are some of the most common signs that your Jeep Liberty’s engine might be having trouble.

Ignoring this warning can lead to more severe problems down the line.

If you experience any of these signs, pull over immediately and let the engine cool down.

Keep an eye on your mileage to spot any significant changes.
Rough Idling
A smooth idle is essential for engine health. If your Jeep Liberty starts to idle roughly, it could indicate:
