Other Fuel System Pump Problems of Chevrolet Spark

Takata recall: I purchased this vehicle oct 9 2015 with 56k miles on it. From the day I purchased it up to today I have been hearing a humming/buzzing/whistling noise coming from the rear of the vehicle. I had it checked out by a repair shop and was told it was a faulty fuel pump with an estimated cost of $500. The noise can be heard only when the car is on and running and it can be heard inside and outside of the vehicle when stopped or moving. It can be heard from inside and outside the vehicle and has only got worse since the day I purchased it. I am a part time uber driver and I own a mobile cell phone repair business and I am in my running vehicle up to 15 hrs/day. I have researched this issue and there are many threds and blogs online with customers complaining of the same issue. I do not feel I should be responsible for this repair charges has the vehicle was making this noise soon after the purchase and I was not notified. This noise has started to affect me mentally as there is nothing I can do to drown it out. I is also starting to affect the performance of the vehicle. Please help. "takata recall" also, since the purchase of this vehicle I have noticed the ac does not blow cold air when sitting at an idle. I live in arizona and temperatures can reach 120 degrees. As I mentioned I am in my vehicle up to 15 hrs/day and many of those hours are spent sitting idling while I repair my customers cell phones. When I am sitting in 120 degree heat with barely cool air blowing on me it makes it about 90 degrees in my vehicle which can cause health issues and worst case scenario death. I am at the verge of selling this vehicle, obtaining a lawyer, and filing a complaint or law suit, especially if my health is being affected. Please help.

I get this loud annoying high pitched ringing sound coming from back wheels. The sound is so loud at times that pedestrians can hear it as I am driving down the street. It does this after I have been driving the car for 30 minutes or more. Once the ringing sound starts it will not stop no matter what speed I'm going or whether I am sitting in idol, park or in any gear. Chevrolet dealership repair department doesn't know what it is but said it may be the fuel pump. What concerns me is that the dealership repair department will not at least check the fuel pump which would eliminate this as the potential problem. It definitely is not a functional sound and it may be dangerous to continue to drive the car when it is making this sound.
