The problem could be either a blown out channel or metamerism. If you could post an image we may be able to help you better.
To solve in post: Have you tried changing the hue and saturation of the yellows in the hsl panel in ACR? If you have Photoshop you may be able to do a selection based on color range and then change the hue / saturation
Shooting in RAW will definetly be a preferable option but it will not solve metamerism because it is a structural issue. Even if you shot RAW, you may have problems in straight conversions to AdobeRGB or sRGB, because the red primary (which is the same for both color spaces, is not very saturated), so any saturated red, yellow and orange will require some tweaking of hue / saturation in post.
