general problems of the 2009 Infiniti G37

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.

My car was slowing down and jerked in and out of first gear ive been having this problem for motnths I looked on Infiniti forum and seen itb12-027d and Infiniti will not fix my car I almost hit someone car due to the car driving really weird ! and swerved and hit a curb instead this is ridiculous im also reporting this to the bbb as well because plenty of people are reporting this as an issue with this years transmission and engine and they arent doing anything to fix it but throw prices at their customers for the to fix tehe problem themselves.

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!.

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.

My car was cutting off and over heating but it eventually locked up on me when I was driving on the highway.

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.

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.

When engine is started it occasionally revs to 4000-5000 rpm and remains there for about 5-7 seconds before slowing down to a normal idle speed. The occurrences are becoming more frequent. When acting normally, the engine starts and revs to about 2000 rpm and then slows to idle speed in about 1-2 seconds. The danger of the high revs for 5-7 seconds is that if the driver is not fully aware of the engine's speed, he could shift the car into gear and the car would accelerate, perhaps hitting nearby cars, house, out the garage door, etc. I had such an incident and was barely able to hold the car in place with full force on the brakes. The dealer has stated that he is unaware of any service bulletins concerning this issue, but if I would bring it in, they would check the settings on the engine control. In my opinion, this is a very serious situation akin to the Toyota unexpected acceleration problem and infinti needs to develop first an acknowledgment of the problem and then a solution.

Car buck and stop accelerate. Then will not go in to low gears or six gear.

While stopping vehicle, braking became non-responsive and engine began racing. Vehicle was extremely difficult to stop completely. After taking foot off of brake pedal, vehicle lunged forward as if accelerator pedal was fully depressed. This has occured on 12/9/12 , 12/10/12, 12/15/12. Infiniti has not corrected problem. This rapid acceleration / non-responsive braking has caused two (2) near miss accidents.

I have 38 pages of service regarding a starting problem. When the car is started with the ac on, it cranks but will not start. There have been 6 battery replacements, one 6 months after the car was purchased and 5 in the last 5 years. Within the last week and a half it has needed 4000 in repairs. A valve assembly, control and now an engine control module. The car was brought in dozens of times and the problem never fixed. Would be happy to provide all of the paperwork.

My 2009 Infiniti GX 37x lost power without warning. The mph went from 50 down to 30 in seconds, the rpms would not go above 1500. Acceleration failed. Power steering and braking still worked. I had to pull over and restart the engine. The first time this happened was July 2009 and the dealership said not to worry, that it was probably an isolated incident and to bring it in if it happened again. If something happens once, I can reason it away. But, twice? this is a major safety issue and Infiniti needs to issue a recall ASAP. Driving conditions have no factor and this problem strips the driver of any control of the vehicle. The dealership did a "reflash" or ecu update and said that a similar problem occured on a "m" model. I am not convinced this has solved the problem. I am terrified of driving this car.
