2009 Infiniti G37 engine problems

Filed Dec 12, 2022 · Electrical, Engine · CA

I was driving at about 65 mph on the tail end of a roughly 2 hour trip. The car shut off on me completely. Fortunately there weren't many cars on the road, so I was able to force the steering wheel - since power steering went out as well, I needed to turn the wheel forcefully - to the shoulder. The brakes worked ok, but not well, again because the engine shut off, so I was forcing the brakes and they took a lot longer to work than normally. Had there been normal to heavy traffic, I'd definitely have been in a very bad crash. The vehicle is available for inspection if needed. This is the second time this situation has occurred to me in this vehicle. There was no warning lamp, message, or symptom prior to or after the incident. A dealer, manufacturer, police, insurance, nor anyone else has inspected or reproduced the problem. Various Infiniti online forums reference the same issue.

After purchasing the vehicle used, I been experiencing issues with the vehicle. The service engine soon indicator has illuminated on the dashboard after two weeks of the purchase. I took the vehicle to valvoline for the oil change service, and the light was still illuminated. Notified my personal mechanic of the issue as well as the dealer. Took the vehicle to autozone and used their free diagnostic reader, which stated the o2 sensor for bank 2 sensor 1 as the issue. Purchased the part from the dealer, took it to the mechanic for service. After I paid for the service, the same day the service engine soon light illuminated again. The next day I took it back to autozone and the diagnostic read bank 1 sensor 1. Took it to multiple mechanics to only have the run around of paying them to look at but not fix the issue. Called the dealer I purchased it from, and they was supposed to set an appointment with their mechanic and did not. I had to reschedule the appointment on my own. Never took it because I went back to my mechanic and he supposedly fixed the sensor. Again, the same day of service the service engine soon light illuminated again, the car stalled very badly, and shut off on me. I was able to restart the engine, and drive it home. Not only am I making monthly payments on the vehicle, I'm paying for a vehicle that is a hazard on the road. I am putting money I don't have into a lemon, only having the vehicle for two months with a electrical and engine issue that I can not resolve on my own.

*the nissan and infiniti oil gallery gasket problem* it's ridiculous how nissan and infiniti have not come forward with a statement about this notorious problem. It's an utter shame how a company does not recognize their failures in their cars. Some nissan and infiniti vehicles are equipped with a paper material gallery gasket that tends to fail at any given moment it does not matter the mileage nor the age of the vehicle it's bound to happen regardless. Nissan/infiniti silently changed the gallery gasket in some pre-2012 production cars to a more reinforced gallery gasket made out of metal part # of gasket: 13533-jk21b - small lower gasket, 13533-jk21a - large upper gasket. Vehicles affected 350z 370z g35 g37 fx35 fx45. Moreover, this problem is inevitable!! Cars equipped with the faulty part can put many at risk of an accident of any sort. Not just that, but the burden of the costly labor that goes to replacing the part. It's time for nissan to pay their part and fix our cars!

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.

Between 40-50 MPH, on a busy rural highway, the car would occasionally (once in 3 months) go into limp mode. This problem is now occurring weekly! You cannot accelerate more 2,000 rpms when this happens. You can manually shift the transmission to a higher gear to get to a safe spot to pull over. However, it feels like the transmission might fall out of the car when shifting. Most of the time, when you cut the car off and restart it, it runs as normal. It's like the computer resets. As of late, I have to cut the car off and restart twice. This is beginning to happen more frequently, like once or twice a week. We have consulted with a dealer, and have tried several recommendations. We have new air filters and mas air sensors. This did not correct the problem. After further investigation, we found a dealership who admitted that they have seen or heard of this problem. The service advisor said that this could be a transmission issue. We have an appointment on 12-13-2019 with this dealership.

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.

Infiniti needs to recall the timing chain galley gaskets. My 2009 g37xs sedan recently blew the galley gaskets and it seems as if this is a common problem and is a very expensive fix. Recall this issue please I always use 93 gas. Always use mobil 1 full synthetic oil, and always do all maintenance on the car on time. I'm shocked and aggravated that this issue happened and infiniti did not recall it.

Gallery gasket blown is common on early models because the gasket is made out of paper.causing the car to go on limp mode.
