Complete center console not working. Stuck on auto a/c with no way to defrost windshield and it was raining. No modes work, no cd, no radio, no heat, no defrost- front or rear. I have already had this happen before, replaced motherboard and it cost me 1200.00 and that was in 2011. Now it has happened again. This is very unsafe. I had my children with me and it started raining and we couldnt get the windshield or rear to defrost so I couldnt see. Why arent all 2003's covered under the recall?????
The charger port had some sort of malfunction and my car was burned to the frame. It was parked in my drive way and had been since 8:00 p.m police officers where coming in my front door at around 2:00 a.m. My car was engulfed in flames.

Twice while driving approximately 70 mph on the freeway, the engine shut off without warning and the service engine soon warning indicator illuminated. The vehicle coasted. There was no shoulder to pull over to. I put it in neutral and it restarted. The vehicle was taken to an independent mechanic where it was diagnosed that the camshaft and crank sensor failed. I looked online and saw a recall for the cam shaft and crank sensors for the, 2003 Infiniti G35. However, when I called, I was told that my vin was not included in the recall. The failure mileage was 230,000.
The car engine cuts off / stalls while driving. This has happened multiple times. When driving on highway, the engine stops running, the car loses all power, and it is very difficult to restart the car. I had the car inspected and the local mechanic stated the crankshaft sensor/ camshaft censor is not working properly and he believed this was on recall, but Infiniti stated that my car is not covered. This is extremely dangerous - call stalls in the middle of the road with no power at all.

I was entering onto the highway and my entire defrost / ac / radio cluster failed. The ac came on full blast, replacing the defrost!!! I had to pull over and park the car due to the safety factor of not being able to run my defrost. The issue is the ac, defrost, and radio stack controls stop working. There is no way to get them to work once the problem occurs. There has been a recall on this for G35''s built in 2002 for the 2003 model year. My G35 was built in 2002 but when I called Infiniti they said my ''engine is the wrong model'' Infiniti needs to fix this thru recall as this is a major safety issue concerning the defrost. I can only imagine if my 17 year old daughter had been driving and the defrost went out. I could have been a very rich man at the expense of my daughters life. I have read where thousands of G35 owners are having the same issue. …
