I took my vehicle into the dealership where I bought it to have an oil change and tire rotation. I asked them to check the cooling system because it wasn't heating properly. They told me that I needed a new radiator because the transmission fluid was leaking into the radiator, and that there's a possibility that radiator fluid could leak into the transmission and ruin it.

I was made aware by another Nissan truck owner that these was recall on the Titan and the Frontier for that exact problem, but my Nissan dealer did not explain/tell me that.

Now I'm truly suspicious of my dealer for not informing me of that recall. Hmmm!
