I am posting the following in the case that someone may go through a similar problem and need some help diagnosing the problem. This is a copy of the review that I placed on Consumer Affairs today.

2009 INFINITI FX35. Car shut off while driving at slow speed, such as a parking lot or slow speed on the road. Just shut off while in drive, no lights on the dashboard until of course it shut off, then the battery light came on and probably other lights. So, I took the car in and the only code showing was the valve body code. I spent $2300 to replace that, got the car back, did it again after driving 29 miles. Took the car back, they said they had to "reprogram the valve body", they drove it around about 80 miles and it didn't have a problem. Got the car back, drove fine the first day, driving to work - got off the expressway and pulled up to a stop light and it shut off. THEN, a couple minutes later, the car completely shut off IN TRAFFIC and almost caused an accident. This time I had driven about 60 miles when the problem occurred again. Each time I was able to restart by putting in park and restarting as normal but that morning was extremely dangerous.
Infiniti of Coconut Creek (Florida) had a tech come pick up the car at my job and give me a brand new loaner as they had all previous times.
Couple things to note: They were able to reproduce the problem when I first brought it in so they didn’t think I was nuts, lol. Most of the time this happened when I came off a fast, busy road such as an expressway or interstate and then slow down to merge onto a slower road. Once I get to that first stop light or stop sign, I got a slight acceleration even though my foot was on the brake and slowing down. That was usually my first sign of trouble when I got that slight acceleration that I didn't ask for.
Three weeks later, I was finally able to pick up my car again and all seems to be well. I have to give special thanks to Infiniti of Coconut Creek for seeing this through, all while providing excellent customer service. End result: Fault EVT Control Magnet Retarder in both banks. During data monitor observation, improper signal sent to the ECM by the EVT Control Retarder. Replace both bank EVT Control Magnet Retarder and check for proper voltage signal. All ok. Pulled VTC Cover on both banks and replaced Solenoid Gasket. NOTE: this particular problem does not throw a code of any kind, so the only way they were able to figure it out was to drive it with a data reader UNTIL the intermittent stall issue presented itself again.
Infiniti of Coconut Creek will DEFINITELY get my business again this coming year when I purchase another Infiniti as a second car for the family. They went above and beyond to see this through and make sure that the problem was solved. This included getting Infiniti USA corporate involved and covering the second repair under some type of warranty. AGAIN, seriously above and beyond excellent customer service. Infiniti will definitely have my business for years to come. I have had many BMW cars and have never gotten this kind of service. Thank you!!!

I think i'm having a similar problem. I have a 2009 fx35 and recently it has been shutting down when moving at very low speeds. Took the car for a diagnosis and the exhaust valve timing control error came on. Changed the piece for the bank with the problem but the car still shutdowns like before and the error is still there.

Did you ever figure out the problem I have a fax 35 doing the exact same thing now

Same story here, I have 2009 Infinti FX35 that stalls at low speed. This is common practice when I go in reverse with my horse trailer. It all started years back with a defect battery, replaced it and since then the issue started to appear. Maybe a coincidence maybe not. The dealer cleaned the whole engine a few times and after each cleaning action it was okay for some weeks and then the issue came back again. I replaced the gear box as the mentioned the first gear slipped. Also this was not the issue. Reading error codes shows that there is an issue with the camshaft sensor.
Anyone any idea what the issue could be?

Hello,

I have a 2008 Fx35 and recently went through a series of random car shut offs. My boyfriend immediately thought it had to do with the fuel pump somehow based on how it was able to restart after shutting off. Reading through this forum, someone had replaced a fuel sensor and said it fixed the problem so we did that first. Car ran fine for a few days and shut off at a light. I took it to my local mechanic who luckily had experienced something similar with a Nissan in the past and it turns out it was the camshaft and crank position sensors. My car has actually been running better since. After replacing those, I was able to feel/hear the difference in how smoothly the car shifts into different gears which I hadn’t even noticed before.

My mechanic said when this happened with the Nissan, they used aftermarket sensors and the issue still prevailed. Instead of buying from the dealer and chance them not working they decided to get the sensors from a junk yard to test before buying them from the dealer. The junkyard sensors worked so they then purchased OEM. They run between in the mid-high $200s and there’s 3 sensors total. Issue was resolved in a few hours.

I hope this helps!

Hi

Thank you Truiz for sharing.
My mechanic didn't believe the issue could be with the camshaft sensors.
So, being in catch22 and the expert didn't want to step into my story I opened the hood and as first step disconnected all 4 camshaft sensors (VQ 2009 engine) cleaned the connectors and connected them again before buying new sensors.
Since then, close to 2 week ago, the issue didn't appear anymore and same as your experienced, my car is running smoothly.
I hope they issue is resolved (bad connection with one or more camshaft sensors).
If the issue will appear again I will buy new sensors but.....fingers crossed.

I'm having the exact same problem with my 2009 FX35 and have stalled in an intersection several times and both while backing at slow speeds.

If you don't mind me asking so how much was the final repair that you mentioned."

Hi, after I had a good result cleaning the camshaft sensor contacts the issue came back after 1 month. This made me guess that the issue was not with the sensor it self but with either the contacts or the wiring. I replaced all 4 camshaft sensors and the stalling issue is gone for more than 2 months.
