Red Fluid Leak – Possible Power Steering or Coolant Issue
A red fluid leak under a 2020 Tesla Model 3 after parking is most likely power steering fluid (if equipped) or coolant from the thermal management system. Tesla uses a specific red coolant for battery and drive unit cooling. A leak can lead to loss of steering assist or overheating, requiring prompt inspection.
Diagnosis Details
Possible Causes
Power steering fluid leak from the steering rack, hoses, or pump (if hydraulic system present; some Model 3s have electric steering, so this is less common).
Coolant leak from the battery thermal management system, drive unit, or radiator hoses. Tesla coolant is often red/orange.
Transmission fluid leak (if applicable) – Tesla drive units use gear oil, typically not red, but some aftermarket fluids may be red.
