Red Fluid Leak - Possible Power Steering or Coolant Issue
A red fluid leak under a 2021 Tesla Model Y after parking is most likely power steering fluid (if equipped) or coolant from the battery thermal management system. Tesla uses a special red coolant for the battery and drive unit. A leak can lead to loss of steering assist or battery overheating, requiring prompt attention.
Diagnosis Details
Possible Causes
Power steering fluid leak from the steering rack, hoses, or pump (if hydraulic system present; some Model Ys have electric steering, so less common).
Coolant leak from the battery thermal management system, drive unit, or radiator. Tesla's coolant is typically red/orange.
Transmission fluid leak (if applicable) – Tesla's drive unit uses oil, but it is usually not red; more often amber or dark.
