What owners say
Like thousands of other g35's, my vehicle's radio and air conditioning controls have become unresponsive. The panel's light goes off and none of the buttons work. The air conditioning unit resets itself to 75 degrees and auto climate, which promptly ramps up and goes full blast, with no way to turn it off. This problem also drains the battery while the car is off. Before I was aware of this battery draining, I was at a gas station at midnight in the freezing cold, when the car would no longer start. I was never told about the problem by infiniti, and they did have a recall for this but for a very small range of vins. According to my dealer, this is one of their most common jobs and non-warranty covered repairs will come up to $1300. Searching online reveals many threads with hundreds of posts about this very same issue. Apparently getting the repair may not solve the problem and it may resurface 3-4 months later. This should be recalled, as it could potentially be very dangerous. I'm lucky I don't live in an area where there is snow or freezing temperatures. You can get stuck out there with no battery.
The radio system malfunctions on an intermittent basis due to cold solder join on radio circuit board. Other engine functions and air conditioning controls are routed through the radio circuit board so when this fails, it presents a dangerous situation. When the radio system malfunctions, the air conditioner is set to maximum setting. Also in some cases, the malfunctioning radio results in battery drain. Infiniti previously issued a recall but the repaired radios also exhibit the same defect. I have contacted infiniti and they decline any responsibility. Local infiniti service manager states this is a well-known issue with infiniti radios. Would like the federal safety agency to compile statistics to determine if infiniti should have extended recall campaign.

1- battery drained every other day. 2- if the infiniti g35- 2003- is not in use for 1day the battery died. 3- I change the battery 4times in past 8 month!! 4- the AC goes to max and I can not turn it off, I was told this is due to the wiering and that is why the radio doesnt work either 5- if this is due to the wiering I am afraid that it might cause fire. 6- beside the wiering issue, unstopable AC, battery drainage every other day are health issue related since I have allergies and it cause eye tears and I cant see properly while I drive not to mention that I have had flue twice so far because I can not turn off my AC !!! I went through the infiniti website and saw many other infiniti g35/2003 drivers had same issue. Please helpppppppppppppp.
Something was draining the battery in the electrical system. One day while trying to start the car after it had been sitting for a few days, everything flickered (headlights, dashlights, control panel) and then the car wouldn't start. Charged the battery and then the radio, AC/heater/defroster did not work properly. Have seen many similar complaints on the internet.
