Question about castle warranty

[CerberusVI]

so I bought a new mamba monster v3 august of last year. 2 months before my warranty expired I ran into issues with my esc and sent it in and received a new esc with my 6.5mm bullets in the box.

Well now I'm having issues with the new one I received, really bad cogging, struggles with any motor I have (1717,1512,1520) on 4s to 6s 40c 5000mah batteries. I pulled it out of my truck fearing it was gonna let out the magic smoke. I checked all my solder joints and tested the motors with my other mmv3 in my MT and everything is fine.

My question is when receiving a new esc does it doesn't extend the warranty at all does it? I'm not too thrilled to shell out another $76 for a out of warranty repair and shipping.

Setup;
Mugen mbx5t prospec
Mamba monster
1520
Zippy 5s 40c 5000mah
Geared: 16/46 for roughly 43mph
