When a customer rolls into your shop asking for a used EV inspection, it’s not your typical oil check and brake pad scenario. A thorough inspection protects your customer and your shop’s reputation.
Battery health is king. The battery pack is the heart (and wallet) of any EV. A degraded or damaged battery can cost thousands to replace. Check the State of Health (SOH) using the vehicle’s diagnostics. Most models, like Teslas, Nissan Leafs, and Chevy Bolts, display this data via the infotainment system or through an OBD-II scan tool.
Use the right software to spot excessive capacity loss or uneven cell voltages. If SOH drops below 70%, that’s a red flag. Also, check for signs of physical damage, corrosion on terminals, or leaks. Coolant leaks from thermal management systems are rare but serious. EVs come with unique challenges, and as a trusted technician, you’ve got to know what to look for.
Used EV Inspection: Test the Charging System and Port Integrity
Verify the onboard charger by plugging the vehicle into a level 2 charger. Make sure the connection is solid and the charging rate is on spec. Look over the charging port for signs of wear, contamination, or damage. A broken port or charger, especially with proprietary parts like CCS connectors, could leave your customer stranded with a costly repair.
Inspect Tires, Suspension, and Brake Wear
EVs are heavy. Those battery packs add weight that wears down tires, suspension components, and brakes. Look for uneven tire wear, damaged bushings, and tired shocks or struts. Examine the brake rotors closely. Because regenerative braking handles much of the stopping, traditional brakes can develop rust or pitting from lack of use.
Used EV Inspection: Check Electronics, Software, and Diagnostic Codes
Modern EVs are rolling computers. During your used EV inspection, make sure everything powers up as it should: lights, infotainment, driver assist features, cameras, and sensors.
Review the software update history if available. Outdated firmware may reduce safety or performance. Use a compatible diagnostic tool to scan for hidden error codes.
Don’t Skip the Thermal Management System
The EV cooling system does more than keep passengers comfortable—it also regulates battery temperature. Check coolant levels and inspect for leaks. A neglected thermal system can lead to overheating, lower performance, or long-term battery damage.
Close the Deal with Confidence and Credibility
A used EV inspection is your chance to help a customer make a smart, informed decision. By focusing on the battery, charging system, mechanical parts, electronics, and thermal system, you’ll not only deliver peace of mind, but you’ll also position your shop as EV-ready.
And when it’s time for that customer to service their EV? They’ll know exactly where to go.
