For a person of many years of experience your friend is the problem. He has agreed to push untested code which is his responsibility, enabled other teams to work out of schedule and him producing dangerous results. All these without any indication that he sought approval from upper management. Why would you use the word "complaining" when communicating an issue? State the facts and how they diverge from the formal process, flag parts of the process that are problematic due to lack of resources of consistency, put them in an email with a "default" course of action if not answered and without using "I" or "They", use passive voice (tone). Keep the score in writing as an informal calendar linked to the respective communications. Cc the manager. Obtain bliss, people will fret then they will forget.

If the team is disfunctional or the manager bad consider changing work. Not only due to the dysfunction but because a good team and manager is part of ones' mentoring, and it hampers ones' growth. At least now you gain some reflexes that will assist you in the future, if you chose to move on.
