However, finally during the Monaco Grand Prix weekend in 2016, both parties made a decision to continue their deal on a two-year contract, but this time, without the Renault name on the engine, being substituted by the Swiss Tag Heuer brand label, a watch company from Switzerland.
Ricciardo will start third on the grid for the Singapore Grand Prix on Sunday, and is considered a good shot at a podium finish on the back of his most recent fast finish in Italy and the fact the Marina Bay tight track challenges driver skills more than horsepower.
Both Porsche and Aston Martin, a long-time affiliate of Red Bull, are thought to be interested in joining F1 depending on the outcome of the sport's proposed engine revamp for 2021.
There was no word from Renault or Red Bull on their future together, following reports that the French manufacturer will walk away from their partnership after 2018.
Honda have been a part of Formula One as a constructor and engine supplier - on and off - since 1964, but they have struggled with current regulations which require a hybrid, part-electric power unit.
Losing Ricciardo would be a major blow to the team as he has the potential to be a world champion, so Red Bull are eager to retain him.
"Our prerogative is to get to the end of 2020 as competitive as we can", Horner added.
"I love competition, it is my dream job, but I kind of don't just want to be here to be here".
"That's obviously what I'm trying to do with myself and Red Bull at the moment, but beyond that of course I want to be in the quickest auto every year".
But the tension has returned, even with Ricciardo's win in Azerbaijan, as it did not help things in the long run.
We will let the video below show you how that went.
"We were obviously close with the field today and we have still got some improvements to make with the vehicle", said Hamilton. There will be further developments with that but that doesn't relate to the engine.
