Buying Tips for 2020 Fiat 500X
- ✓Check for electronic parking brake (EPB) faults; they can be expensive to fix if the calipers seize.
- ✓On 1.4 MultiAir models, verify the oil service history is impeccable—the MultiAir unit is sensitive to oil quality.
- ✓Test the DDCT (Dual Clutch) automatic for smooth shifts; it is better than Dualogic but still complex.
- ✓Inspect the front suspension for knocking—bushes and drop links wear on UK roads.
- ✓Check the infotainment system for freezes or reboots; software updates may be available from a dealer.
- ✓Look for evidence of regular oil changes—Fiat's engines are sensitive to extended service intervals.
