Have a 2013 Foz and a couple weeks ago started hearing a squeal when I get to 35-40mpg. The noise is steady with the speed of the car, not the engine. As I start to decelerate the noise gets quieter and more high in pitch until I stop then it's quiet. Needed tires so thinking it's my brake pad warning since I needed brakes, too, I got tires, brakes, new pads and rotors and an alignment. Drove away only to hear the same noise. They want to replace the belt but I can drive until I hear the sound, shift into neutral and rev the engine and the noise starts steady.
Any ideas what this might be???
Totally stumped the local shop. Drove and got the noise started, put it in neutral, turn the engine off and noise stayed steady. Put it on the rack and could not get the noise to start no matter what was done. So I left, took a back road and tried to find some sense to when it does it. No one on the road so decided to just blow it out. Floored it and got up to about 60mph. When I slowed I didn't hear it. Accelerated normally and heard the noise but not much, kind of intermittently. Drove hard several more times and then I could not get it to make the squealing noise. Not sure if it has to do with the driving hard or the engine warming up but tomorrow when I drive I'll see which is true with that.
Update - It's totally odd.... after gunning the crap out of things and driving as hard as I could several time yesterday it seems that it did something as today i once again tried to make it squeal but nothing. Totally quiet. And totally baffling.
