Broken leaf spring hanger 2015 Cycclone 4200

Is not that uncommon of an occurrence, have been told it can be caused by backing up over curbs or other obstacles while traveling too fast. The springs and shackles are designed to give in forward motion only being the shackle allows for the necessary movement for the springs to flex. When going in reverse, this feature is nullified being the shackle is not following the spring but leading.
Usually ends up with broken springs but I have heard of hangers bending etc.

Its still welded to the frame. It is a 3 sided bracket and both sides snapped off at the 90 degree bends

Probably more common if you're pulling a 20,000 lb GVW triple axle toyhauler.

I've got 18,000 miles on my 2015 4200 Cyclone. So far no issues in regards to springs or chassis. As Dan stated earlier, it's not a common occurrence. I suspect either a defective weld or significant impact such as the high curb backwards as stated by richheck. I will admit I try to avoid curbs and sharp turns.

If it is due to backing why wouldn't the front hanger break as it is solid and leading the spring?

My .02 cents
I think its from a combination of poor design and lots of u-turns and twisting side to side on windy roads. I had the same thing happen on my 2 axle toy-hauler after traveling up Hwy 1 on the Ca coast.
Clean it up, make a new hanger, weld it on and beef up the rest of them while you at it. weld in a cross support inside each one of them. Then you won't have to worry about them anymore.

Weakest link will usually break first, OP just wanted to know if problem was common.
As Jerrod suggests, weld it up and re support as suggested - could have been just a bad weld but it needs to addressed.
Thanks for all the insight. I'm just a little baffled because I have had the trailer for 2 1/2 years and 15-20K miles. I put Carlisle tires on it the week I bought it. the tires still have about 50% of their tread with no sidewall or wheel damage evident. Luckily I backed the trailer in the shop where I keep it with plans to check the brakes. When we jacked it up we discovered the issue. It appears due to rust that one side of the bracket was cracked for awhile and the other side is clean. The plan is to re weld and reinforce the bracket. I was just trying to find out if this was a freak occurrence so I knew whether to go to the expense of reinforcing the balance of the brackets.

Ti also appears to be the rear Rt hanger correct?

Yes it was the right rear hanger. And yes I noticed it after I had slowly back over a driveway apron, like maybe 3 inches, not a full curb. And if you look at the rust, it was probably already cracked and the backing bump finished it off.
My plans for the off season are to get it back to the frame shop that fixed the hanger and have them install a heavy duty shackle kit with wet bolts and weld square tubing in the hangers.
Good luck with your repairs and safe travels!!!
