Why is my Subaru crosstrek shaking at idle?
If your Subaru Crosstrek is shaking at idle, it could be caused by a few different issues. The most common reasons include problems with the engine mounts, fuel system, or ignition system. Let's take a closer look at each of these potential causes and how to troubleshoot and fix the problem.
Engine Mounts
The engine mounts in your Subaru Crosstrek are responsible for securing the engine to the vehicle's frame and absorbing vibrations. If the engine mounts are worn out or damaged, it can cause the engine to shake excessively, especially at idle. You can inspect the engine mounts visually for cracks or signs of deterioration, and also check for any excessive movement or play in the mounts. If the engine mounts need to be replaced, this is typically a straightforward repair that a mechanic can handle.
Fuel System Issues
Problems with the fuel system, such as a faulty fuel injector or fuel pump, can also lead to an engine that shakes at idle. When the fuel system isn't delivering the proper amount of fuel to the engine, it can cause uneven combustion and vibrations. You may also notice other symptoms like poor acceleration, stalling, or the engine running rough. Diagnosing and repairing fuel system issues often requires specialized tools and expertise, so it's best to have a mechanic inspect and service the fuel system.
Ignition System Problems
Issues with the ignition system, such as faulty spark plugs, ignition coils, or the ignition control module, can also cause an engine to shake at idle. When the ignition system isn't providing the proper spark timing and voltage to the engine, it can lead to misfiring and vibrations. Replacing worn spark plugs or other ignition components may help resolve the shaking issue.
Other Potential Causes
- Loose or worn engine components (e.g., pulleys, belts, hoses)
- Transmission or driveline issues
- Problems with the engine's internal components (e.g., pistons, crankshaft, bearings)
If you're experiencing a shaking Subaru Crosstrek at idle, it's best to have a qualified mechanic diagnose and repair the issue. They can use specialized tools and techniques to identify the root cause and make the necessary repairs to restore smooth engine operation.

A little bit of slight vibration is no big deal.

Why does my car judder when idling?
If your engine doesn't get an even and continuous distribution of clean fuel, it can start to shake or shudder while it idles. If the judder only happens when idling, it could be a small leak on the vacuum side of the engine, or a worn-out electrical component such as the crankshaft sensor.
