Hey guys, I had my G37 for 3 days and I loved it. Last Saturday I woke up to get lunch, when I press the ignition start button the engine would turn on but my instruments (speedometer, gauges, dash lights) would flicker on and off. Eventually it stayed off. I left my engine one for a minute or two and tried again. That time it flickered maybe 3-5 times and everyone came back on with the Service light on.
It flickered again when I came out from lunch but everyone turned on okay after 3-5 flickers. Eventually the everything was fine that day, minus the service light being on. I drove to the Infiniti dealership and get my car fixed, but I forgot their service department was closed on the weekends. I left a voicemail regarding the situation. I went home around 9pm, was a little stressed about my new car.
Sunday morning around 10am, i started the car again and everyone came on smoothly. The service light was actually OFF. I was relieved. I had an appointment to installed an amp and sub (JL 500/1 and 2x 10" JLw3). This was done by professionals (Custom Sounds). They took about 3 hours to finish the installation. When I got the car back, everything was working great! sub sounded good and no problems with the G what so ever. I was very pleased and went to bed at 11pm knowing my car issue was resolved.
Monday 7am, I started the car to head to work and it happened again! The engine turned on, but the panels flickered. This time it flickered about 15-20 times and eventually turned everything on, of course with the service light on as well. I called Infiniti when they opened so the salesman drove to my work and gave me a loaner while he drove it back to service.
Later that afternoon I received a call saying that the problem was caused by the aftermarket audio system. I explained to them that this issue happened before the audio installation (they actually called CS to check if I installed it on Sunday). I left my car there for night.
This afternoon, I received a call saying that the issue was caused by the "tripper" cable coming from the amp. I drove to CS during my lunch break and asked them about the wiring and they told me about the wiring process and it should not effect the car at all. Apparently the "trip cable" to turn on the amp was wired to the lighter (I was told this only drains ~1Amps) and this could not be a problem. However, the tech at Infiniti says this is causing "secondary" issues with the electronics. But they called some Infiniti place in California and supposedly they are sending in an "Electronic Modulator" that should resolve my issue.
CS manager talked to the Infiniti tech, and the tech told him he cannot plug the trip wire there. The CS guy asked where was he suppose to wire it, but all he got from the tech was "I need to ask my boss, I will call you tomorrow".
I apologize for any grammatical or spelling errors. I'm typing as quickly as possible so I can get to bed.
After all inconvenience, what do you guys think about this? Is the Infiniti dealership feeding me bull****? Or was there some wiring gone wrong?
Thanks for your time,Kream
