I was watching a video on YouTube and one of his 'final thoughts' sums up this thread.
Skip to 16:50 for power comment
I am on the edge of picking up a 2019 Sig or GTR ($4500 off) and this power issue is what's putting me on the edge. If not for the potential power issue, it would be in my garage.
I've watched that before and he seems to comingle issues in that comment...he initially talks about cold weather loss of turbo in the CX-5 (but not in the Mazda 6), and then he talks about an inconsistency with turbo power being there one moment and then not the next moment (in other words, just a "sometimes gone when it's cold" issue).
We've had someone here mention a consistency issue (unrelated to temperature), and another member responded with words to the effect that all turbos have some type of power decay...that successive use of turbos yielded less boost on each subsequent use. I could never find any backup to the assertion that turbos (or the engine) need some time to "fully recharge" after being deployed. If I feel like it later, I'll go spelunking for that thread and post a link here.
Savagegeese made his turbo comments at the very end of the video, yet didn't mention a turbo problem
once during the entire test drive...no real-time example and discussion of exactly what he observed and his trying to duplicate it. He just sat on it, or he edited it out, or he was recounting an issue he did not experience first-hand. I think this is a very odd thing to just tack onto the end, considering it's probably his most crucial criticism of the car and the most major issue he raised for many potential buyers and owners.
In fact, typing this caused me to go to the video and ask SG "what gives?" What gives with the passing mention at the end with no discussion (or demonstration) of this most crucial problem during an extended test drive, and what gives with this problem in general? (I should have asked the question when the video was fresh.)
