From the pictures it appears site grading and poor water runoff management is putting excessive amounts of water next to the foundation. The uneven drive is a classic example of subgrade failure due to excessive moisture. To make matter worse the one photo looks as if the drive is now sloping towards the house.
As a home inspector I would note cracks and possible settlement and suggest further investigation needed.
As a Structural Engineers my advice would be first develop a plan to manage the grading and runoff issues then second depending upon the foundation type and the severity of the settlement look at mudjacking and/or screw anchor jacks to restore the foundation to the proper elevation.
This is the short version, there are more measurements and cost estimates that need to be done to verify my assessment and to determine the most economical solution for this homeowner.
