Germany has drawn four of its last five games – surrendering the lead on three occasions – to leave it second in its Nations League group behind Spain, AFP reported.
Germans squeezed past Ukraine 2-1 with a full strength side in Kiev on Saturday and after a 3-3 friendly home draw against Turkey last Wednesday, Loew's side was once again guilty of poor defending.
"Sure, when you concede three goals, the defense isn't good," admitted Toni Kroos, who was at fault for the second Swiss goal, after his 100th appearance for Germany.
The 60-year-old Loew has a German FA contract until the 2022 World Cup.
However, his popularity among German fans has plummeted, from the heights of winning the 2014 World Cup title, since Germany's debacle at Russia 2018 finals when it failed to get out of its group.
The draw with Switzerland will only enhance the domestic criticism of Loew from key names within German football such as Lothar Matthaeus and Bastian Schweinsteiger.
Dinamo Zagreb striker Mario Gavranovic scored goals either side of a deft chip by Remo Freuler as all three Swiss goals came from German mistakes.
Germany fought back behind closed doors with goals by Timo Werner, his Chelsea teammate Kai Havertz and Serge Gnabry.
"We always came back, despite a lot of setbacks, so we showed some good morale," said goal scorer Havertz, putting a positive spin on a disappointing evening for the Germans.
Loew also focused on the few plus points.
"Of course, we also see the mistakes, which we have to fix," said Loew.
"It was good that we came back. It shows that the team is eager.
"These mistakes are part of the process."
On the eve of the game, Loew said he expected "concentration, precision, courage", but it was the Swiss who showed those character traits to take a 2-0 lead.
The German defense was caught napping with just five minutes gone.
Right-back Robin Gosens lost the ball and Freuler headed across the box to Gavranovic who also used his head to guide the ball over German goalkeeper Manuel Neuer.
A weak clearance by Neuer then invited Gavranovic to claim his second, but the Swiss striker fired just wide.
The Swiss grabbed their second however when Toni Kroos, making his 100th appearance for Germany, surrendered possession.
Haris Seferovic flicked the ball across the box to Freuler, who had the time and space to chip Neuer on 26 minutes to leave Loew fuming on the sidelines.
Germany fought back with two 'Made in Chelsea' goals.
Kai Havertz won the ball and unleashed his Blues teammate Timo Werner, who beat a posse of defenders before delicately placing his shot out of reach of Swiss goalkeeper Yann Sommer to make it 2-1 on 29 minutes.
Having hit the post immediately after half-time, Havertz equalized on 55 minutes when he snapped up a loose ball and fired across Sommer to tuck his shot inside the far post.
However, the Swiss claimed their third goal when Gavranovic slammed home a shot on 57 minutes after the German defense had again been pulled apart.
It meant Germany has conceded six goals in Cologne in the space of seven days.
The Germans came back again when Werner turned provider and threaded a pass to Gnabry, who deftly flicked the ball past Sommer with half an hour to go to equalize for the second time.
