Guenther Steiner says it is "not possible" for Mick Schumacher to continue crashing his Haas at the rate he has during the opening seven rounds of the F1 season.
Schumacher has suffered big shunts in both Saudi Arabia and Monaco, leaving the team with multi-million dollar repair bills.
He also collided with Sebastian Vettel in Miami, all while failing to score a point for the team during the first 28 races of his F1 career.
Steiner says he has spoken to the 23-year-old about the incidents, though has tried not to pile pressure on his young shoulders.
However, the team boss has to concede that the squad cannot afford for the German driver to continue crashing so frequently.
"I think he knows that it is not good for the team to crash. If I would have had to explain that to him then he shouldn't be here, he knows the damage," said Steiner, speaking to media, including RacingNews365.com.
"We [have] passed [the team's crash budget]. We passed that in Jeddah. We are beyond the allowance for crashes. We need to try to make savings somewhere else.
"It's just not possible to continue like this, and he knows this. Even for him, crashing into a wall is not healthy, at some stage. He wants to score points; if you do that you don't score points."

Steiner warns "serious chat" could be on the horizon
Along with costing his team cash, Schumacher has his own future in Formula 1 to think about.
The youngster, part of Ferrari's young driver programme, is a reserve driver for the Scuderia, and the possibility of him one day racing for the Italian outfit as his father did has often been speculated about.
But would another crash over the Azerbaijan Grand Prix weekend call for a serious chat, between team and driver, about Schumacher's future?
"I would say so," Steiner admitted.
"At some stage, we run out of parts; we cannot keep up making them, even if you throw money at it, physically you cannot do it. We need to make sure that, here, nothing happens.
"He just needs to adjust himself and not do what he did in Monte Carlo.
"There is no one simple answer. There are a lot of things we need to sort out now."
