Just days after the latest Red Bull quit threat, Renault's Cyril Abiteboul says he understands Dietrich Mateschitz's "position and frustration."
In the wake of the Malaysian GP, the Red Bull owner once again threatened to walk away from F1.
He told the Austrian Press Agency that he will "only stay in Formula One if we have a competitive team, and we need a competitive power unit for that."
However, instead of the team recording a good result at the next race, Red Bull's woes were compounded.
While Daniil Kvyat retired with yet another engine failure, his team-mate Daniel Ricciardo could only manage ninth place.
Called before the press at Red Bull's post-Chinese GP briefing, Renault F1 MD Abiteboul was asked about the latest quit threat.
He responded: "I understand his position and frustration, and to a certain degree I'm sure Renault's board could share the same frustration.
"We understand we have issues. Those issues are supposed to be addressed by some of the many things going on at Renault Sport.
"There are things waiting to happen. There is a plan, and we need to understand if that plan is commensurate with the issues we've seen on track.
"This plan was more focused on power because we saw that was where we were missing. We've got all the driveability issues completely out of the way.
"Now we need to understand the reliability issues because a problem with reliability is bad%
