Baking light on LODs problem

Anyone know how to solve this?

I'm trying to bake a vehicle with LODs and I have this issue where shadows and light are very different from the first LOD to the others. The shadows go almost black and the light is more saturated.

The light is set to baked and scene is set to only use baked GI.
I have all lods set to same scale in the object lightmap settings.
