| The issue of the car radio and air conditioning controls going out along with some other dash lights is a well documented issue. I had a 2003 where the unit was replaced under warranty as a known defect. The replacement unit lasted about a year and a half and started showing signs of going out again. I have since traded the car in on a 2007 which is totally awesome. The service manager said that he feels the problem is caused by a lack or loss of contact. If you have the issue I would see about working a deal or getting a discount due to the fact it is a known defect. | |

Checking back in (my car had the slow battery drain problem). I've had my control module replaced, and had the radio repaired by a Bose repair outfit, that says they do one a day for the nearest Infiniti dealer. Following that: first my interior lights failed to work. My repair guys did something to the unit to reset it and now they work. But the dead battery issue is back. I had to jump start the car three mornings in a row this week; now I'm disconnecting the battery at night. It goes back into the shop on Tuesday to have a new control module installed; they believe my "new" module was defective. I'm starting to seriously think about trading the car in, even though it's paid off and I love it otherwise.

In Feb, 2008, I bought a new 2008 G35. Since then, I've taken it back to the dealership 3 times for the same problem. I start the car and none of the functions controlled by the center console/computer work. It's frozen for about 10 minutes. The nonoperating functions include heat/air, all stereo functions, blue tooth phone connection and the satellite clock (not the manual clock). The clock will be stuck at the time when I last drove the car, which has always been several hours or less earlier. I assume the problem also affects the navigation system, but I haven't yet used my nav system so am not sure. The car itself drives fine. Windows, door locks, etc. work. After about 10 minutes, and before I can make it to the dealership, everything starts working. Dealership keeps my car several days and then gives it back to me saying they can't duplicate the problem and there's nothing they can do. My car is still under warranty, but that doesn't seem to matter. The dealership is indicating that it's not going to do anything, and from reading other posts, I'm not too optimistic about Infiniti. For now, I'm just going through the motions that my warranty book says I have to. Any advice or solutions would be greatly appreciated.

Here's the latest. Several days ago, I used a multi-tester to measure the drain with the car off, at the 12v battery. The ONLY fuse that makes a difference when pulled is the 15A fuse in the block right by the battery. With the fuse in, it ranges from 0.8 to over 1.0 A. Pull the fuse and it drops as low as 0.02. I've gotten the vehicle service manual and examined the schematics closely -- that fuse only covers the radio/CD/AC controls (it would cover the NAV if I had it; I do not). The 15A fuse in the kick panel block is only for the (optional) Bose amp in the trunk, under the upper deck, which I do have. I did try pulling that fuse with no change. I also pulled the harness plug out of the amp just to be sure; no change in draw. My radio was repaired by an outfit that does many, many of these G35 radios per WEEK. I'm going to be back in touch with them tomorrow morning to see what my next step is. I'm all but convinced there is something left in that radio needing repair, and then my troubles will be over -- for at least a little while. BTW, I did look into the aftermarket center dash console solution -- it has AC controls, and allows you to put in a different radio. By the time you're done, I think you could easily spend a grand. And the plastic only comes in one of the two interior colors (not mine, "willow" -- of course)... But it may come to that yet. I've been driving with the aforementioned 15A fuse pulled for a week now -- the car has started each and every time. The AC is on where I left the settings before pulling the fuse. The radio/CD, of course, is out... But at least I can drive and no dead car in the morning...

| Even though I'm not heading down this path, these aftermarket dashes clearly must work -- Crutchfield is one of several reputable dealers that sell them, and have for a few years. They wouldn't if they did not work. I can see where a service tech, not having seen one, would figure that you'd lose your AC control. But the aftermarket console HAS the AC controls and circuit board/harness built in. You can see it at Crutchfield's website. Also, somebody sells them on ebay -- same unit. The downside to me is twofold -- first, the color does not match my willow interior (they sell the more titanium interior color), and second, between the consolde, harnesses, steering wheel control adapter module, new stereo, etc. -- it's a lot of money to put into a car actually manufactured in the Summer of 2002. For my own situation, I'm going to try again to have my Bose repaired, and hope to do that this week. I will be able to see the drain go away (or not) on my multitester before I drive home! | |

Replying to: airjoe (Oct 12, 2008 7:09 pm)  http://www.autotoys.com/x/product.php?productid=9777 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? |
