DIY Mechanic Check: Before Visiting a Shop
- Visual Inspection: On 2.4L models, listen to the front passenger engine cover. A loud rattling on cold start means the timing chain tensioner and guides have failed.
- Check Fluid Levels: Verify engine oil level, coolant level in the reservoir, and transmission/power steering fluid condition.
- Replicate Under Control: Note whether the sound happens when moving or stationary, and if turning the steering wheel alters the pitch.
