Passenger side rear making rattling noise

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A rattling noise coming from the passenger side rear of your 2015 Kia Forte can be quite annoying and might indicate a few possible issues. Since it sounds like it's near the trunk area, there are a couple of things you can check: 1. **Loose Items in the Trunk**: Start by checking if there's anything loose in the trunk or under the spare tire. Sometimes, items can shift and rattle, creating noise. 2. **Trunk Lining and Covers**: Inspect the trunk lining and any plastic covers or panels. They can become loose over time, especially if they’ve been removed for any reason. 3. **Suspension Components**: If the noise persists, it could be related to suspension components like the rear shock absorbers or struts. A worn or loose part can rattle as you drive, especially over bumps. 4. **Exhaust System**: Check the exhaust system for any loose hangers or components that might be vibrating against the car’s frame. If you can’t find anything obvious, a visit to a trusted mechanic for a thorough inspection might be the best bet to pinpoint the source of the noise.
