I bought a 2003 G35 in 2004. In 2007 with 58,800 miles on the car the radio/air conditioner problem happened. The dealer replaced the radio unit which fixed the issue at no charge as a known defect. I had the 60,000 mile service done at the same time. About a year and a half later it started to happen again but before it completely broke I lost the car to flooding. I purchased a 2007 G35. The dealer told me it would cost $300 to replace the car radio again.

Ira, the fact that the problem happened again certainly seems to point to the Car Radio being the source of the problem as I have been reading. For whatever reason, it causes excessive current drain on the circuit board which causes it to run hot and eventually malfunction over a period of time. This is definitely a poor design manufacturer's defect on part of Infiniti. I can understand these problems because I have an electrical engineering degree and something like this should have never left design and been released into production. I am glad that they replaced your circuit board at no charge and at least resolved the problem for a year and a half later. I dont seem to be getting even that far with them. I am claiming this as a safety issue. Even this morning I could not operate my defrost. Do you mind me asking what dealer you worked with?
 
thanks..

This was at West Houston Infiniti in Houston, Texas. Excellent service and customer relations. My 2007 G35 is the third car I have bought from them. I believe 2003 was the first year the car came out so I would expect some little nagging problem.

WOW! This is VERY discouraging news to read, I purchased a 2004 G35 and my 6 Disk CD player JUST stopped reading disks!! Now with all of the posts I am reading suggests that this is the tip of the iceberg. I thought I was making the best choice by not buying the Lexus, because of repair costs, hopefully, I didn't slip from the frying pan into the fire...will keep you all posted.

My 2003 G35 Battery Drain problem is FIXED! by nickdecarl

OK, now you can ignore all my previous posts -- here's the final scoop. I was measuring just under 1/2 amp draw at the 15A radio fuse next to the battery (fuse pulled, ignition off). I left the fuse out for two weeks and the car started every time. Convinced that the radio was causing the problem, I contacted the shop that repaired my CD changer (and supposedly the circuit board) back in August. They told me 1/2 amp draw was normal. At this time I became aware of another shop, Factory Car Stereo Repair, Inc. in Longwood, Florida (www.carstereohelp.com). I talked to two different guys there, and both told me the draw should be nearly zero at that fuse, ignition off. So I made arrangements to drive to them (two hours). First they metered the draw and got the same measurement as I did. Then they took the dash apart and pulled the radio (no easy task). They repaired the circuit board, and bench tested it, to confirm "no draw." While the dash was apart, they offered to replace the two small light bulbs in my dash clock, as they often die -- one of mine was bad. Then they re-installed the radio and dash. Everything worked with one crucial difference. Back at the 15A fuse (fuse pulled, ignition off), the draw was ZERO instead of 1/2 amp. Further, the car has started fine for the last week, even on the cold mornings we've had here in North Florida the last few days. Can you guess that I'm thrilled? I cannot overstate how pleased I was with the service, problem-solving methodology and expertise demonstrated by the three guys who helped me out at Factory Car Stereo Repair, Inc. All told, it took them about 2 1/2 hours to do the work. You can imagine how gratifying this was after taking a day off from work and driving two hours. But this problem had truly been drving me crazy. Their repair fee was incredibly reasonable too. They told me that they have fixed MANY of these 2003 G35 radios, and are seeing more and more of them. Good luck everybody and thanks for the many clues and information that helped me reach my solution.

Kdooley, I figured out that when I don't play my radio the problem don't occur. I haven't played my radio since August and the problem stopped. I know the problem still needs to get fixed and to make matters worst my cd changer is jammed and I cannot load or unload cd's. They told me at the dealer that I can trade my radio in for a new one and it will cost me $500 including labor. They said my radio is causing the vircuit board problem. I'm going to change the radio and then change my car.

2003 G35 Electrical Problem Resolution? by kimbracrowe

I have read all of these messages and I would love to hear from someone who has had a resolution to the climate control/audio problem. I live in Atlanta and the dealer I have used for service is Infinity of Gwinnett. I bought this car 3 years ago from them.I have really enjoyed owning this car so far - not one speck of trouble.
 
I called Infinity of Gwinnett and explained my problem and was told that in 95 percent of these cases replacing the stereo fixes the problem. If that does not do it the the dash module needs replacing also. But they said start with the stereo.
Their quotes were $800 to replace the Bose and 1300.00 for the module!
 
I can't see how fixing the sound system will restore the other dash functions??
I am not sure where to start? I have been laid off - so I have not been having to drive very much- but what if I need to defrost/defog my windshield? The ac is set at 67 degrees on auto and not on full blast like some I read about.
 
Please reply with some success stories!

We ended up having the ignition switch replaced about two week ago at a cost of $170 at KAM's in Acworth. We haven't had a problem since, but the problem was intermittent, so time will tell. Our problem was that the dash lights, ac control panel and stereo would go black and not work. We could giggle the ignition and it would come back. The repair shop said they have replaced several ignition switches in the Infinity G35 and thought that would take care of the problem. Now we have a different problem. The brake and slip lights stay on. We haven't investigated that problem yet -- just started yesterday.

The best way to solve this problem is putting an after market radio, kit cost about $160 plus the radio, cabling and installation. I bought a Infinity G35 2003 the dealer put about two factory radios on it and they will work for a day and break AGAIN the dealer where i bought the car did the same thing to all their Infinities G35s problem solved!!!!!!! it cost the dealer $305 the bough a cheap radio which ill change later.
