Infiniti G35 Electrical Issues
Hi all,
My 2003 G35 coupe at time would turn off all electronic while driving. Headlights are ok, but A/C, radio, CD and all the buttons on the console do not work. It happens once awhile. My warrantee has expired. Does anyone here have similar issue and how were you resolving it.

I have a substantial parasitic drain on the battery. If the car sits for more than 24 hours or so, it drains the battery completely.
I've been told the battery was too old and not holding a charge. Replaced the battery - w/ no effect.
Later told there was a short in the trunk release switch. Replaced switch - to no effect.
At this point - my CD exchanger failed. It seems to have developed a mechanical problem - and a microprocessor in the system burned out. Replaced the microprocessor and CD exchanger. At first, we thought this might have been related to the electrial problem, but after the repair, the drain remained. [Note, the work on the CD exchanger was quite involved. Not even the dealer would touch it. Had to disable the airbags and remove the dash to get at the system.]
The drain was tracked to the circuit which controls the radio, HVAC etc - but we've tested all the lines shown on the schematics that run off this circuit. Now at a loss - where else to look. I presume their are additional lines off this circuit - but without knowing where to look - its like finding a needle in the haystack.I've seen references to another radio circuit board - but not sure if that is my problem. All systems on the car seem to be functioning.
I'm taking the car back to the dealer next week and would appreciate any further guidance to help direct them in the search.
Point being, a specialist in tracking this stuff down will trump the dealer most times.
Google "auto electric city state" for your location and see what comes up.

VOLUNTARY SERVICE CAMPAIGN 2003 INFINITI G35 SEDAN; AUDIO FINISHER CIRCUIT BOARD
On some model year 2003 G35 Sedans manufactured through August 21, 2002, the audio and temperature controls may not operate as expected. When using the audio equipment or the temperature controls, the unit may become inoperative. In some cases, this can be corrected by turning the ignition switch off and back on again. In other cases, the unit remains inoperative and requires service by an Infiniti technician. To prevent this condition, Infiniti has initiated a Voluntary Service Campaign to replace the audio finisher circuit board on these vehicles. Use Infiniti Net to confirm if a specific vehicle is affected by this service campaign (P3104).
Also, I was told by Infinity dealer that I absolutely could not put an after-market stereo in my car because the a/c controls would not work. Does anyone know if that is true?
I spent enough money on repairs on a Lexus the last year I owned it to put a nice down payment on a new car!
They're money pits!
Nothing but problems!
The Dealerships must love them, real "money makers" for them!
Count your blessings!
I drive a Mercury Grand Marquis now for 2 1/2 years and haven't had *any* problems with it! A great car!
I have the same problem with my 2003 coupe. Car turns over strong but does not start. No code from the computer. Checked all the fuses and relays that I could find. Can hear the fuel pump prime. Sprayed starter fluid into the intake. It did not try to fire on it. Act's like it's not getting any spark. Changed the crank and cam sensors. No help.
Thanks, ~Scott
I was looking on autotoys.com and if you use the above link, you'll find aftermarket dashkits which allow you to change to an aftermarket radio. Is this possibly a fix for the radio/ac audio finisher board problems?
I also found this response to the radio/ac control problems:
AC controls are dead, stereo does not power up, no functions work. This is not a front face problem like the dealership may lead you to believe. This may be one of two problem, a bad ribbon cable connection pointed out in our removal instructions or most likely a stereo problem. Repair rate will range $185-295.
========================
This is only one repair service, but a very popular one.
The repair could involve the ribbon cable connecting the audio system components together or a problem inside the cd player itself.
Being and Infiniti is means the cost of repair will be little more than a less luxurious automobile.
I suggest you take it to a local car install/repair shop and get an estimate from them. It should not be so expensive as having to pull it out and send it off to a far-away place.
And, if it is the ribbon cable the repair might be nothing more than pulling the cable off, cleaning the contacts and carefully reinserting the cable ends to get good contacts.
But, this being an expensive model you should have it done by professionals. The Infiniti dealer is probably NOT the place to go unless they do have a trained audio system expert on staff (only a small percentage of Infinity dealers do have an expert)
The dealer has filed a claim with the consumers affair today and I'll wait and see what Infiniti will do this coming Monday. If they choose not to do anything, I must say that I will be VERY VERY upset and will pledge not to buy another Infiniti/Nissan as long as I live. If they can't take care of this problem, I would vote that we should all band together and make an impact at Infiniti... Enough people bringing this problem to other potential customers attention could cause enough negative impact to Infiniti's business that Infiniti might consider being responsible for a problem on their end and NOT the consumer. It is ludicrous to think I have to shell out $3000.00 to have use of my heating/air and car stereo in a luxury vehicle.
Anyways.... I wish all the best with this. I am hoping from the best. We should all support each other in this. I will keep everyone tuned in. Please those with this problem share your experiences.
Thanks so much for sharing. This confirms how much I detest Dealerships - the fact that I am quoted close to $3000 and you had yours fixed for $300.00. I think they just want to soak up money from customers. That figure came straight from the dealership. I have it on the work order. I spoke with the manager in the dealership and told him I knew about a service recall on this very issue. The service campaign is noted as ITB03-007b. It can be found by googling it. HOWEVER, the manager tells me that my VIN number falls outside of the cars that are covered. IN other words Infiniti only chooses to address a small portion of the cars that were affected by a manufacturers defect. I imagine they are quoting me that number for one or two reasons. One - to scare me away or Two - because they dont want to repair it but would rather just replace the whole audio/electrical sub system.
Either way this is a serious problem with Infiniti, and I hope they will address it. I would love to get more information on how you got your problem resolved and where you went to resolve it. It has been very difficult not having use of my AC/Heat. I am in Atlanta and we are just starting our winter. Although, I know the winters are mild here. You do have to use the defrost, so I could say that it would be a safety issue.
JMK
It does NOT matter what your VIN number is. The part only cost around $300 and you just add the hour to swap out the unit.
For a circuit board?
Are you sure it's not a Lexus?
Thanks so much for your post.
That is exactly the same dealer I am dealing with and I suspect I am getting the same run around. I will get an attorney involved if I have to. Infinit needs to take ownership of this. They do not want to take ownership for what is clearly a manufacturer defects. I am glad you posted. I can certainly appreciate what Ira posted, but it DOES matter according to Infiniti what your VIN is. It is on the Service Recall bulletin. You can download it off the internet. In the bulletin, they mention that only some 23,000 cars are affected. I would venture to say that is a very low conservative estimate. I am sure that there lack of Quality Control to carefully disign a circuit board for a Luxury car is the reason why this is a huge problem among 2003 Infiniti G35s.
Ira could you please share with kdooley and myself how you managed to get your problem fixed for $300.00. That certainly is much better than the same story that both kdooley and myself have been told at around $3000.00.
As far as the stereo having to be replaced too. I believe that is the case because I have found articles on the internet pointing to the a flaw being found in the car stereo which causes a huge current drain which eventually causes the finisher board to go out. Some Infiniti users have even had their batteries drain and go dead on a recurring basis.
I also agree with you that this is certainly a safety issue, when due to changing weather conditions or if their is rain and I can't operate my defrost then I have a serious problem on my hands which could cause an accident.
I hope that Infiniti will choose to address this and take it more seriously than they have been.
I think I should post an attachment of the service record from the dealership. Seems too unbelievable. Perhaps having an image of the document scanned would blow everybody's mind like it did mine when I saw it. I imagine the quote is to replace more than the circuit board and includes the stereo, since the dealership claims that the problem will resurface if the car stereo is not replaced.
thanks..
