Esteban Gutierrez was frustrated after practice in Spain, saying Haas' reliability troubles are making him looking "very bad to the outside as a driver."
Gutierrez completed Friday's second practice at the Barcelona circuit down in 21st place, over four seconds off the P1 time.
The Mexican racer covered just nine laps in the 90-minutes, however, it was by no means his fault as his VF16 suffered an electrical issue that kept him on the sidelines.
It is not the first time that Gutierrez has had a problem with his car and the former Sauber driver says it is making him look "very bad" to outsiders.
"I honestly put myself aside from this because it's not really my responsibility to fix the car," he told reporters at the Spanish track.
"The team has to get on top of this.
"I am here to drive, to drive as fast as possible, and it is what I really love doing.
"It's not nice because it's making me look very bad to the outside as a driver, personally.
"All the f***ing great job I'm doing on the inside is not really perceived by the outside. So it's a little bit frustrating on that side.
"Also, showing my pace, I've been quick, I just hope to get the car that I deserve in order to put the results on paper."
But despite the troubles, Gutierrez, who has yet to score a point this season while team-mate Romain Grosjean has 22 to his name, says he feels "very good" as a driver.
"I don't worry about myself. At the moment I feel very good.
"Every time I drive the car I enjoy it a lot, I'm on top of everything and I'm doing my best with what I have.
"But this pressure is not on me, this pressure is on the people responsible for it."
