Short answer: A brand-new CX-90 should not drip oil. Photograph it, keep the level safe, and make it a warranty visit—not a 'wait and see.'
Symptom: Oil spots on the ground, wetness near the turbo or front diff, low oil warning, or a dealer finding a gasket/seal seep on a low-mile CX-90.
What to check first
- Photograph the leak path before cleaning.
- Book a dealer warranty visit immediately.
- Check oil level until it is repaired.
- Ask for the exact failed part on the repair order.
Likely causes
- Turbo oil-feed gasket seep. Owners have posted low-mile oil leaks traced to turbo oil-feed gaskets.
- Front differential / axle seal leak. Some leaks show at the front diff area rather than the engine valley.
- Other new-vehicle seeps. Any new CX-90 oil leak should go straight to the dealer under warranty—do not wait.
What it usually costs
Should be warranty-covered on a new vehicle. Out-of-pocket would be moderate to high depending on labor access.
Is it safe to keep driving?
Top off if low; do not ignore a growing drip.
DIY or shop?
Inspection DIY; repair is dealer/shop.
