Tl* the contact owns a 2004 Infiniti G35. The contact stated that the driver and passenger side reflector lamps failed to illuminate and were replaced on two separate occasions. In addition, when refueling the vehicle, fuel would spray out of the fuel filler neck even though the fuel tank was not filled to the full capacity. The VIN was not included in NHTSA campaign numbers: 06e060000 (exterior lighting) and 05V555000 (fuel system, gasoline). The vehicle was not repaired. The contact also mentioned that after starting the vehicle the air bag warning indicator illuminated intermittently. The vehicle was taken to the dealer, but the mechanic could not locate the cause of the failure. The manufacturer was not notified of the failures. The approximate failure mileage was 173,000.

I recently bought a 2004 infinity g35x for my daughter. It was disclosed at purchase that the 3rd brake light was out but I figured that was not a dealbreaker, I would get the light fixed easily. Well, I contacted our local infinity dealer and was quoted $480 to replace a 6 LED board!! What?? After doing research online I discovered via infinity car forums (g35driver.com, x.infinitihelp.com, nicoforums.com) that this is an extremely common issue with these vehicles. The OEM board is known to be a defective design. This is a federally mandated safety issue! Infinity should be made to recall and repair these bad brake lights. It is the law that these lights be there and working. I sincerely hope someone at your branch will take notice of this issue and force the manufacturer to make it right.
Third light failed at approx 62800 miles 5/24/2013 .this is a well documented issue with this vehicle, causing an unsafe condition due to improper warning to following vehicles. This is a very costly repair and should be covered by a recall. To date Infiniti has done nothing to correct.
I am the owner of a 2004 Infiniti G35 sedan. The high mounted brake light, also known as the "third brake light" stopped working on my vehicle 15 months ago. Due to my fear of someone rear-ending me, or the inevitable stop by a police officer, I decided to take action on my own. I replaced the original and broken LED brake light, with an aftermarket LED light that was purchased off ebay. I understand that all light bulbs eventually burn out, but LED bulbs are not supposed to do so after twenty to one hundred thousand hours. I was forced to replace safety light on my vehicle, at my own cost, when inifniti/Nissan should have provided a functioning product in the first place. The reason I complaining about this is because nearly 75% of Infiniti G35 sedans from similar model years as my 2004, have a failed "third brake light". …
The third brake light on the rear deck has failed for no apparent reason. The car will not pass inspection. They want several hundred dollars to replace the entire unit. I have researched online and found this is a voluminous problem for this model year. It was recalled and addressed by Infiniti for the 2003 model year g and it is still a problem for the 2004 year. This needs to be recalled and fixed accordingly at the manufacturer cost. All these owners are not having the same failing issues without cause. I own two 2004 Infiniti G35 sedans. I used to love both of them. This one has problems with the brake light and now the airbag light is mysteriously blinking for no reason! The other one has had issues for years with being able to put gas in and I have had problems at the gas station trying to fill the car! Ridiculous! If Infiniti doesn't do something ... I'll be switching makers. …
I'm the second owner this particular vehicle, and although I did not notice the problem sooner, the 3rd light on my 2004 G35 does not work (my car does not have the spoiler). What I did was purchase a used 3rd light from a salvage yard....and it did work (briefly), now it's not working.....so I'm back to square one. I thought that it was unusual, so I googled the issue and much to surprise came up with many hits of owners of this vehicle with the same issue.......since reading the issue others have experienced with the 3rd light not functioning I have noticed this particular vehicles 3rd light issue on other G35 on the road, more than likely the owners have not noticed the light not operating.........the whole purpose of the 3rd light is to be seen by others driving behind you.......it's an accident waiting to happen, I hope the NHTSA and Infiniti takes steps to correct this problem.
There is a common failing issue with the 3rd brake lights of Infiniti G35 sedans that was manufactured in between 2003-2006. Infiniti/Nissan fixed the problem with the new generation (starting 2006) however they do not seem to response well to customer complaints for our vehicles. This causes potential threat to highway security. Please make Infiniti recall these vehicles and fix the issue. I have replaced the light once but it keeps failing because the issue is the board, not the LED lights. Thank you.
