Air pump started making squealing noises on cold start so pump was replaced but noise was still persistent so dealer told us to drive car for 500 miles to break pump in. Noise persisted car back to dealer and dealer called GM. GM told dealer that this should not be making said noise so dealer replaced pump again. Now second pump had to be replaced because pump starting making the same noise on cold and hot start. Car back at dealer for noise and now dealer has said there is nothing they can due for the noise. Dealer said GM technician said this is normal for this model year and make of car. Can you please advise? This noise is why we took car in to be serviced in the first place.
