My 2012 Mazda 5 sport appears to me to be lower in the rear than it should be. It also seems to be lower than it was a year ago when I got it. There is nothing loaded in van to cause the droop. Any suggestions as to what’s wrong and what is needed to repair.

 

I would inspect your suspension components mostly the condition of the rear shocks.

 

Like was noted, check out the shocks. Life expectancy for shocks is around 50,000 miles, so with an eight year old car they’re likely worn. May need to swap out the springs as well as they can also get worn out depending on the driving conditions they’ve seen.
