I’m having a problem with my 2012 Mazda3 (automatic, non-skyactive model) that others seem to be complaining about on the online forums, but there seems to be no consensus.
About 10,000 miles into owning the car, it started making a sort of high-pitched gargling sound when I accelerate and the tachometer reads 1500-1900 RPMs. At first, the sound occurred sporadically when I was accelerating under these conditions, but now, at 28,000 miles, it’s happening almost every time I accelerate between 1500-1900 RPMs. Here are a few more facts:
The engine must be warm
The car must be in drive (I cannot replicate it in neutral or park)
The sound occurs regardless of whether the AC is on
I took it to the dealer 3 times. The first time, they changed the belt, and that helped for about 1000 miles. The second time, they told me that the noise is normal, and I should not worry. The third time, I took it to a different dealer, and they put a “dressing” on the belt. That helped for about 600 miles. Now the sound is back again, and it’s driving me nuts. It definitely doesn’t sound normal. If I test drove a car at 28,000 that made this sound, I definitely wouldn’t buy it.
I’d appreciate any suggestions.
