Cracks from Garage Floor to the house
There are 2 types of concrete, concrete that cracks and concrete that hasn't cracked yet. Houses are essentially floating on dirt and with proper preparation you can minimize the likelihood of a slab cracking. From the picture it does look like a large crack if it happened all of a sudden and is heaving it may cause an issue due being unlevel/trip hazard. But in general cracks in slabs are pretty common. Sidewalks don't crack often because of the expansion joints in between each section of sidewalk but that's impractical for a basement or garage slab. If it's a new build it may be cause for conren or if your house is an area subject to landslides or the sort, you may want to have someone investigate it.
