My fuel pump went out 3 days after I purchased my qx56 so I had the dealership repair it but after I got it back the whole dash was in and out but after a while it stopped working completely and there is also random wires hanging. Before they did the fuel pump the dash was working perfectly fine and I seen no wires. I told the dealership about this and they told me it was the instrumental cluster and then tried to charge me an arm and a leg for repairs. So is there any tips on fixing this problem myself and/or knowing what the real problem is???
