2013 Cadillac ATS Long Term Road Test


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.

    I see many cars on the road, mostly "crappy" or "poorly maintained" looking cars that sound like a thousand raging birds chirping when accelerating. This is probably a completely different issue, but please tell me what that sould is. It is fairly common.

    you may want to check the FEAD components as well... any of the belt accessories could be making the sound or the belt could be slipping/seizing, especially when the engine changes revs suddenly.
