Six problems related to power train have been reported for the 2007 Infiniti G35. The most recently reported issues are listed below.
Powertrain control module my car keeps dying out at stop lights and on freeway yes by a service center auto care precision tune autocare just dying out on freeway when have to stop and go on freeway. It started doing this about 4 weeks ago as of today. 6/7/2021.
Two different incidents - I was in two minor low speed incidents. I believe at the time of the second the brake rod got bent (which is currently speculation and the insurance is investigating) from the first accident. After the first my accelerator would not function on some left hand turns. I got in the second accident because of the inability to "brake harder" and I was amazed I couldn't stop in the distance provided, and this braking scenario and outcome is repeatable. If I brake hard -- harder -- full stop. By the time I do a full stop my braking power is diminished and in my accident I was unable to stop in a "normal" distance. Furthermore, after this second accident at < 20 mph. I have intermittent accelerator failure in all driving scenarios. I could be driving and it just cuts out. No error lights in either of these scenarios. No check engine, no slip, no abs, warnings. I previously tried to bring it up to corporate Nissan and they said I had to contact the local dealership. Both dealerships I tried pawned me off to parts department, which the guy was confused as to why I am asking him about potential short falls. They wanted over $1,000 each issue to investigate. Meanwhile as I now find my car unsafe to drive for lack of accelerating and braking abilities, and the insurance company is investigating. Two accidents in 6 months, and at least the latter I think could be due to a potential faulty part - as every mechanic I have reached out to said if it is the brake rod, and in the accidents I had, it should not have bent (if that ends up being the root cause). Let alone the accelerator issues.
There is a hesitation when accelerating from stop and the vehicle is warmed after about 10 minutes of running. When tachometer hits 1100 rpms the engine sputters down to about 800 rpm and jerks forward. This does not appear to be a transmission issue as this happens every time whether in drive, park or neutral. Vehicle has only stalled once so far. There appears to be reports of this being related to a rear timing belt shield gasket. This is very concerning with the vehicle stalling.
I own a 2007 Infiniti G35 sedan. The vehicle hesitates/stutters/surges when slowly accelerating from a stop. This mainly occurs when the engine is cold (after a cold soak). The failure occurs while turning or driving forward and was noticed at 5-30 mph and rpms are between 700-1800. The vehicle was taken to the dealer on numerous occasions and they "could not duplicate failure. " this is dangerous as the vehicle engine surge could cause a collision.

I have had many problems with my G35x most notably the car jerks violently at or around 38 mph, I have called consumer affairs and the dealer and they both deny there even being a problem. The color is liquid platinum and there seems to be metal flakes in the clear causing there to be thousands of tiny rust spots on the paint.
