Problems with 2009 Infiniti G37 ENGINE

On average, the 2009 Infiniti G37 starts to “feel” problems with the ENGINE and its various aspects after 79 169 miles.

Recently reported ENGINE problems on 2009 Infiniti G37

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.

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.

Rear galley gasket failure, vehicle is out of warranty, but only has 56k miles on the engine. is daily driven and not used for any driving outside of the day to day routine. contacted the dealership and while they see these gasket failures often they were unable to do any type of work on the vehicle due to it being outside of the warranty. the fix will be to replace the gasket which will be a 4,000$ repair, on a car that is only 9 years old and has low miles. this failure occurred while my wife was driving and instantly threw the car into limp mode, because of the lowered oil pressure reading, which resulted in a car unable to continue highway speeds and without knowledge of what limp mode was and what was occurring this could be a very dangerous situation that appears to be a common failure in the vq37vhr engine. i was surprised this isn't already a recall issue.

Code p0524. engine oil pressure, caused by my manufacturer installing bad gaskets. common problem on all 2009 g37 infiniti models.

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

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.

Without warning rpm's drop to about 2,000 and vehicle will not go over 30 mph and just stalls with no option to break. turning the car off for 30 seconds seems to reset the issue, but this very dangerous because it happens randomly. there is a tsb on this, but it should be recalled! it has happened several times and it's very scary and could result in a fata crash on the highway.

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.

I was driving on the highway and my car suddenly vibrate really heavy and then the car suddenly started to rapid decelerate no dash board warning light. the car would not accelerate and i have to quickly try to pull off the side of the road. the car never stall. i have shut the car off and restart it and it seems fine again and may not occur for awhile. i took it to the dealer as this is the third time it happen to me on the highway. *tr

My 2009 infiniti g37x lost power without warning on 3 separate occasions. the first two times the problem occurred in jan 2013 (car was still under 60k miles warranty). i was driving on the highway on a cold night and my car stalled at around 55/65 mph mark. the car was shaking when i tried to accelerate. when i pulled over to the emergency lane, my car had lost complete power. then, i restarted the car and the engine acted and sounded normal. i warmed up the car for 5 minutes before i drove home. i went to infiniti to get the problem fixed and i reported the problem to infiniti of north america. infiniti could not identify or re-create the problem. on dec 7, 2013, i noticed my car acted like it was losing power when i accelerated the car to 65 mph while i was on the highway on a cold rainy night. i tried to accelerate and the car felt very choppy and shaky as if it was choking on something. since this problem had occurred two times before, i decided not to continue to increase acceleration to the car any further. i pulled over to the emergency lane, parked the car, and i video recorded the problem. there was no lighting indication of any problem on dashboard. while the car was parked and the engine was running, i tried to rev up the engine. the car was shaking intensively when it was rev up to 2,000 rpm. i also restart the car and i tried to rev up the engine again and the car did not shake. after restarting, the car engine acted and sounded normal. i was able to drive the car home safely. there is a safety issue with this model. i've reported this problem to infiniti, but they denied there is any problem. infiniti needs to issue a recall on this model. i am scared to drive this car, but i need the car to get around. if anyone can help push forward this issue to the right level of attention, please contact me at [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

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. *tr

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

Tl* the contact owns a 2009 infiniti g37. the contact stated that the vehicle stalled without warning while driving. the failure was experienced several times. the vehicle was towed to the dealer. a diagnostic test was performed, which located the failure at the engine. the dealer stated that the engine failed due to poor maintenance. the vehicle was not repaired. the manufacture denied assistance with the repair. the vin was not available. the failure and current mileages were 27,000.

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.
