1 Check Engine Light On problem of the 2009 Infiniti G37

Failure Date: 06/20/2020

I was driving my vehicle on a state highway with no breakdown lane, only a �soft shoulder� going about 70 mph in the middle lane. There was a vehicle in front over me going about 65 mph and the furthest left lane was moving closer to my speed. When there was an opening, I signaled and began changing lanes when the vehicle began jerking and losing power. There was a car approaching fast in that left lane and also the vehicle that was behind me in the middle lane began closing in. I nearly caused a three car pile up trying get over to the soft shoulder. These vehicles are equipped with a vq37vhr motor which Infiniti equipped with a paper gasket in the depths of the motor called a �galley gasket�. Its cheap fragile design causes loss of power and for the vehicle to not exceed 2500 rpms which is very unsafe for highway driving as many times it is necessary to safely navigate or even exit the roadway. The paper gasket causes inevitable demise to the motor allowing oil to enter where it should not. This is all before the check engine light even illuminates. Once the light comes on, it will display a code �p0011� and/or �p0021� which calls for the variable valve timing solenoid to be addressed. I replaced both, changed the oil, and the car drove fine for a few days then the same thing repeated. After going to numerous shops and them either not wanting to take on the job or not knowing what else the issue may be, I went to the Infiniti dealership and was told that I need a new motor. After extensive research, I've come across thousands of owners experiencing the same issue. The more handy ones with time have discovered this �Nissan� cork paper gasket causing the issue. Infiniti designer and manufactured these motors with poor quality gaskets then charge the customer upwards to $3000 to fix the problem they caused through their own negligence or over $5000 for a new motor.

2 Check Engine Light On problem of the 2009 Infiniti G37

Failure Date: 11/24/2019

Vehicle's engine stalled (shuttered, acceleration lost, felt like choking) at highway speeds, about 50-60 mph, creating a dangerous situation and I needed to pull over onto the shoulder immediately as the car decelerated to under 30 within seconds. The check engine light came on soon after. Searched "2009 Infiniti G37 engine sputtering" with hundreds of similar results, somehow Infiniti dealerships were never able to reproduce the defect. This car is extremely dangerous and Infiniti needs to start placing human lives over their sales.
