Was 4-wheeling yesterday and the electronic stability control light came on. It turned off after restarting the engine but I scanned codes and got C1252-92, P258B and C0077-00. Seems to relate to the vacuum pump.

Curious how common this issue is? Any advice to fix?

Just an update in case anyone finds this thread through search.

The dealer replaced 2 vacuum lines. Probably a small vacuum leak.
