Risk guide

How to inspect battery pack impact

The battery pack sits underneath the car. Minor shield scrapes and structural battery-pack impact are very different risks. Lift the car and inspect edges, mounts, bolts, cooling pipes and high-voltage harnesses.

Job: viewing decision For: pre-purchase review Verify with diagnostics
