Used EV Buying Checklist: 10 Things to Check Before You Buy
Before buying a used electric car, check battery health, charging hardware and port type, DC fast charge speed, software version, recall completion status, vehicle history, tire condition, onboard charging capability, and remaining warranty. These EV-specific factors are what separate a great used EV deal from an expensive mistake.
The 10-point used EV buying checklist
1. Battery health and estimated range
Ask the seller or dealer to charge the vehicle to 100% and show you the estimated range on the dashboard. Compare it to the original EPA-rated range for that trim and year. A car showing 85–90% of original range is normal for a 3–5 year old EV with moderate use. Below 80% warrants a discount or walk-away.
For Tesla: Check the battery section in the Energy app. Ask for a screenshot at 100% charge showing estimated range.
For others: Use an OBD2 adapter and apps like Leaf Spy (Nissan Leaf) or Torque Pro to read battery state of health data.
2. Charging port type
Know what charging standard the vehicle uses before you buy:
- Tesla NACS (North American Charging Standard): Native access to Superchargers. Many new non-Tesla EVs are adding NACS ports.
- CCS (Combined Charging System): Most non-Tesla EVs. Works with Electrify America, EVgo, ChargePoint, and many others.
- CHAdeMO: Older Nissan Leafs and Mitsubishi. Network is shrinking — factor this into your decision.
3. Maximum DC fast charge speed
Range tells you how far you can go. Fast charge speed tells you how quickly you can keep going on a road trip. Faster is better:
- 350 kW: Hyundai IONIQ 5, Kia EV6, Porsche Taycan
- 250 kW: Tesla Model 3/Y (latest), Chevy Silverado EV
- 150 kW: Tesla Model 3/Y (older), Ford Mustang Mach-E, VW ID.4
- 50 kW: Older Nissan Leaf, Chevy Bolt (older models)
4. Recall status
Check NHTSA.gov with the VIN for any open recalls. EVs have had recalls for battery management software, charging issues, and various safety items. Completed recalls are not a problem — open unrepaired recalls are a red flag.
5. Vehicle history report
Run a Carfax or AutoCheck report using the VIN. Look for: accident history (especially structural damage), salvage or rebuilt title, flood damage, number of previous owners, and service records. Even a minor accident can affect battery cooling system components.
6. Level 2 onboard charging capability
All EVs can charge on Level 1 (standard 120V outlet, very slow). For practical home charging, you need Level 2 (240V, typically 7.2–19 kW). Check the maximum AC onboard charging rate — some base models charge at 7.2 kW while others support 11.5 kW or 19.2 kW. Higher is better for overnight charging flexibility.
7. Software version and feature access
For Tesla, check the software version and whether key features (Sentry Mode, Dog Mode, FSD hardware generation) are present. For other brands, check whether over-the-air updates are still supported and whether any subscription features (like GM Super Cruise) are active or have expired.
8. Tire condition and age
EVs are heavier than equivalent gas cars and put more torque through the tires. Check tread depth (minimum 4/32" for safe driving, 6/32"+ is better) and the tire manufacturing date on the sidewall (format: WWWW/YY). Tires over 6 years old should be replaced regardless of tread. Budget $600–$1,200 for a new set of EV-appropriate tires.
9. Remaining warranty
Check what warranty remains:
- Battery warranty: Most manufacturers cover the battery for 8 years / 100,000 miles. This is the most important coverage for a used EV.
- Powertrain warranty: Usually 8 years / 100,000 miles.
- Bumper-to-bumper: Usually 3–5 years / 36,000–60,000 miles. Likely expired on older used EVs.
Check the original sale date and mileage to calculate remaining coverage.
10. Test drive and charging test
Drive the vehicle on a mix of surface streets and highway to feel regenerative braking, acceleration, and any unusual noises. If possible, plug into a DC fast charger and verify that it charges at the rated speed. A car that charges significantly below its rated speed may have a battery issue.
Frequently asked questions
How do I check battery health on a used EV?
The simplest method: charge to 100% and check the dashboard estimated range against the original EPA rating. For more detailed data, use a brand-specific diagnostic app or OBD2 reader.
What mileage is too high for a used EV?
EV batteries are built for longevity. 100,000 miles on a Tesla or Chevy Bolt is not alarming if battery health is strong. Focus on battery state of health rather than mileage as the primary indicator.
Should I get a pre-purchase inspection on a used EV?
Yes, for any vehicle over $20,000 or with unknown history. An EV-certified mechanic can inspect the battery cooling system, check for coolant leaks, read diagnostic codes, and assess charging system health. Well worth $150–$200.
