 We have had 3 infinitis and have been very happy until this G35. The circuit board controlling the AC, heater Stereo, CD etc.will not work. It has been stuck with no stereo CD and AC has been at 64 degrees for the Last 8 months. We have been told it will cost $1500-$2000 to fix it if we are lucky. This seems so outrageous to us. We feel infinite has let us down totally. This should be a recall as the mechanic said many cars of this model have come in for the same problem. We are VERY disappointed in infiniti and would never buy another if this is the way they stand behind their clients. So sorry.
