2013 Cadillac ATS: Chirping Sound

February 21, 2013

2013 Cadillac ATS

I noticed an odd little sound in our long-term 2013 Cadillac ATS the last time I drove it. It's a muted chirpchirpchirp that happens briefly during moderate acceleration from a standstill. The sound only occurs immediately following the 1-2 upshift and can be reproduced fairly easily.

It sounds vaguely like light compressor surge from the turbo, but the conditions aren't quite correct to produce that. The noise doesn't sound malignant in any way, more like just a weird little idiosyncrasy. I suspect it's one of those "they just do that" things.
