Note: there's also a screw behind the glovebox that must be replaced as well.

Is your car ok now?My 2007 FX35 nightmare was originally diagnosed as "bad gasoline" by a nissan dealer. They quoted me $3000 for the coils and ECM. They forgot to mention that the ECM would be covered under warranty if an infiniti dealer installed it. I had it towed to an infiniti dealer, but they can't get my car running either. This car only has 49,000 on it. It ran great, no warning lights at all. It just began to rough idle and then it just stopped running. I'm going on one week without my car and it's 250 miles from where I live. I have already paid $800 in towing and repair bills from the nissan dealer. Frustrated!!!!
This is my 4th infiniti. I've never had an issue like this. Has anyone had any luck with infiniti customer care? This is obviously a widespread issue.
SYMTOMS: Sputtering, shaking, deceleration, jerking, etc...I think Infiniti has a problem with their electrical system based upon what I have read and had happen to my FX35. I have a 2007 FX35 with 90K miles. The car started to drive rough and then completely shut down on the interstate. The repair shop found the engine misfiring on 3 cylinders. $3000 later, the electrical grounds have been replaced along with 6 burned out ignition coils and one fried ECM. Sounds to me like some shotty engineering. The repair shop had to take it to Infiniti to have the ECM reprogrammed and they asked if they had seen anything like this. The Infiniti technician indicated that they are starting to see a few FX35 with 70-90K miles tickle in with this problem. Since I have read essentially the same scenario from at least 3 other people, I suspect this the is the tip of the iceberg. So report to it and save you receipts/documentation. Just hope my cat converters haven't gone bad from the unspent fuel being dumped by the misfiring engine, that seems to be the next step in this repair process.
I had the same issues with the coils and I even experienced the complete shutdown of my car during rush hour on the 405 freeway. The lord must have been looking out for me because an accident had occurred in the middle lanes. CHP had the right 3 lanes blocked, I happened to be in the 4th lane. Long story short, car shutdown completely, I managed to strong arm my vehicle off of the freeway and call AAA. 3 auto mechanics, 1 auto electrician and 12 new coils, 1 ECM later, and many resets of my check engine sensors. The most recent, 1 week ago on another busy SoCal freeway; back to the mechanic on 5 cylinders. New coil and then he told me that I would need to replace my catalytic converters. Price is steep for those.
I decided to "Google It", found this and several other threads with people experiencing the same issue. I also found the Infiniti Service Bulletin (ITB11-017) as a step-by-step pdf for this issue.
Found reasonably priced parts at infiniti parts deal. They arrived in 2 days.
You're going to have to
1. Replace the steering member mounting bolt on the right side (requires removal of the glove box).
2. Clean all the engine harness grounds
3. Replace the negative battery cables
4. Replace any damaged ignition coils.
End results, my "check engine" light went out right away. My rear inside dome light which had not worked in at least 3 years is working. My gas gauge appears to be back on track. I will keep my fingers crossed and I will update in 1 month.
hi everybody
Finally yesterday the car is back on the road. So replaced the ECM, new coils, and the alternator this last was the culprit of the problem, besides reviewing each ground connections and installing two AWG6 wires, one to ground the negative pole of the battery to the engine and the other engine to body frame. Lucky I have been to meet an excellent electrical engineer, a dominican who was trained in the US besides he attended a course in Japan at Nissan's. Thank you everybody for helping. By the way you can believe that, a gentleman had to replace 70 coils in 2 months so I directed him to the same engineer who detected that his car had the same problem as mine. It is amazing that some technicians just replace the coils and do not examine the reasons for that behaviour. So long friends let me enjoy the smooth driving of my FX35.
