Thanks for sharing your experience! That's really helpful to know it was the ECU in your case. Been worried about potential repair costs would you mind sharing what you ended up paying for the whole job? Also, has everything stayed good since then, or have you noticed any other quirks pop up? I appreciate the tip about finding an Infiniti specialist. These cars can be pretty complex when it comes to electronics.
Hey! Glad I could help with my experience with the G35. Since you asked about the costs I ended up paying €625 for the ECU repair and programming. Honestly, considering how crucial the ECU is for the car's operation, I thought it was pretty reasonable. And you'll be happy to know that since getting it fixed by the mechanic, my car's been running like a dream! No more stalling, no more rough running, and definitely no more warning lights. It's been about 8 months now, and I haven't had a single issue pop up. The engine control problem was definitely the root cause of all those symptoms, and once they sorted that out, everything went back to normal. It was totally worth finding a specialist who knew what they were doing. These Infinitis can be tricky with their electronics, but once you get them sorted, they're really solid cars. Hope this helps with your decision making! Let me know if you need any other info.
Just wanted to update everyone I took your advice and found an Infiniti specialist in town. You were spot on it was the ECU causing all the trouble! Got it fixed last week, and what a difference it's made. The whole repair came to €680, which wasn't as bad as I was fearing. The mechanic was great really knew his stuff and explained everything clearly. They had to keep the car for three days to get the new ECU properly programmed, but it was worth the wait. Took it for a long drive yesterday, and it's running better than it has in months. No more unusual shutoffs, no warning lights, and the engine's super smooth now. Such a relief to have it sorted! Thanks again for sharing your experience it really helped me make the right decision. These Infinitis might be complicated, but they're great cars when everything's working right! Really appreciate all the help!
I had a similar issue with my '06 Infiniti G35 last summer. The symptoms you're describing sound exactly like what I experienced unusual stalling, rough idle, and starting problems. Turned out my ECU (Engine Control Unit) was failing, and it was causing all sorts of electrical gremlins. Took it to the Infiniti specialist in town they ran diagnostics and confirmed the ECU was shot. It was pretty serious since the ECU controls basically everything in the engine management system. The repair involved replacing the ECU and reprogramming it to match the car. Had to leave it at the shop for a couple of days. Would definitely recommend finding a specialist who knows Infinitis, as these issues can be tricky to diagnose correctly. The fix sorted out all my problems, and the car's been running perfectly since then.
