Red Bull powertrain reliability still in question

Both Red Bull and Alpha Tauri haven't had the best start to the year in terms of reliability concerning their power unit. With both Red Bulls and Pierre Gasly retiring during the race in Bahrain, and Yuki Tsunoda out in Q1. This all comes after Red Bull took over powertrain responsibilities from Honda this year, as the Japanese outfit closed their division.

Relentless powertrain issues.

This highlights a big issue looking forward to both teams as they aim to finish as high up the constructor's standings as possible. Especially with the Red Bull team who are pushing to try and take a fifth world constructors title this year. 

It's apparent that Tsunoda's issue today was concerning as the driver claims "I didn’t feel anything in the car, but the team told me there was a problem and I had to come in.". Alpha Tauri suspects it was a water system issue that the Alpha Tauri suffered in Q1. Which was a new engine put in today, before FP3 so now both he and teammate Gasly are already on their second set of parts before the second race has even begun.

Again would bring more alarm as it's yet another issue that will need to be fixed, as it doesn't appear to be related to the fuel issues their sister team suffered in Bahrain, while Gasly suffered something they suspect was battery related.
