Frequently Asked Questions
What actually breaks on used Model 3s?▼
Mostly small things: front control-arm and link joints that creak ($200–$900 at EV-capable shops), and the 12V battery that early cars consume every 2–4 years ($100–$350). The big battery and motors have strong longevity records.
How do I check the main battery?▼
Charge to 100% (or note the displayed full-charge range) and compare against the car's original spec — a healthy pack typically retains 85–90%+ after five years. A big gap is your negotiation number, since range is the car's value.
