2009 Infiniti G37: check engine light

Filed Sep 11, 2020 · Acceleration, Engine · 186,000 miles · NC

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.

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.

My 2009 infiniti g37, third owner, has always had its scheduled maintenances through infiniti. Took the car in because of a rattle sound coming from the undercarriage. Dealership diagnosed it as "internal engine damage." no indication from the vehicle that their is a problem with the engine. There has never been a check engine light detected or any other symptom - other than the "rattle" sound - that would discern an engine problem when driving the vehicle. Infiniti consumer affairs will not help me, and say that I have no recourse. Now, the car is at infiniti of west chester, pa and I need a brand new engine! The car has less than 60,000 miles.

I was coming out from the freeway at the traffic light the car completely shutdown, and it will not start. First I called for aaa to tow it, once he came the driver checked the battery and he told me the battery was fine, then he told me the engine is gone. And then I called the dealer to check if this is a recall, or anything and I was told the power train was expired. I have no indication of any heating, or any engine lights, everything was working fine. I do the maintenance as recommended by infinity book. The this vehicle has low mileage 2009 year made and I don't drive much. I searched online and there are so many people suffer exactly like me.

We picked up our brand new infiniti g37 sedan out of town (52 miles on it) and the next day, drove it home 300 highway miles. Obviously, we were extremely fortunate the problem didn't begin on the trip. By the second day, the car started dying when we came to a stop. At first, the problem didn't happen every time we slowed down, and we discovered putting the car in neutral proved helpful. We hoped it was a fluke that would quickly abate. Unfortunately, by the next day, the problem worsened, and the check engine light went on. We took it to the local dealer, and with infiniti, they determined the torque converter was locking, and the car needed a new transmission/drive train - apparently, they found a po744 error code. This is our 3rd infiniti, and we've never had a single mechanical problem with the others, and both dealerships (the one we purchased from and the local one handling the service) claimed they'd never seen anything like this on a new car. I'm afraid what might have happened had we needed to stop suddenly in traffic. To reinforce the magnitude of this problem, the warranty repair estimate (thus far) stands at $11,000 (retail would be $16k+). In light of how significant the problem, I'm scared to drive a vehicle which immediately required this type of repair. Infiniti's consumer assistance department has turned the file over for review but will only look into whether the situation qualifies for replacement under applicable lemon laws. They won't consider owner loyalty or problem magnitude of the problem, and I remain very concerned about future safety.
