Sergio Perez has been left concerned by Red Bull's technical issues after experiencing another problem during the Miami Grand Prix.
The Mexican reported that he was losing power whilst chasing Carlos Sainz in a battle for P3. Whilst the team seemed able to keep on top of the problem – which Perez later said was a sensor fault – the driver lost time to Sainz, and he feels that this had an impact on the rest of his race.
"I think it was a sensor issue that we had," Perez told media, including RacingNews365.com.
"Throughout the race, it was working well, but then when we had the sensor issue, we lost like seven seconds in two laps, and then it was just a poor race."
When asked if the car had come back to him, Perez added: "No, it was never the same. I was losing too much time.
"I was like 10kph down on the straights."

Perez urges Red Bull to "work hard" on issues
Reliability woes have been a concern for Red Bull in the early stages of the 2022 season. Both Perez and Max Verstappen recorded DNFs at the opening race in Bahrain due to technical troubles, and another retirement followed for Verstappen in Australia.
Whilst Perez was able to finish the race on this occasion, he believes that the team still have work to do in staying on top of their different mechanical issues.
"We need to keep working hard, because every time we [are] finding different issues," he explained.
"Luckily, we managed to finish the race; I think at one point [it] was really close to [being] over. So to get that [result], and [to] be able to finish the race is good."
Perez finished the race in fourth, whilst teammate Verstappen took his third victory of the campaign so far.
The Ferrari duo of Charles Leclerc and Carlos Sainz separated them in P2 and P3 respectively.
