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.

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.

When driving at various speeds the car rpms will not go above 2500 rpms. As I was driving the car lost power and started to stall. I have had to put the car in neutral and coast to a stop from 70 MPH. This has happened now at least 15 times over the last two years. Many posts I've read that infiniti is aware of the issue but I have yet to find a solution. The issue is very dangerous and know of many others that have had this issue from posts online.

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 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.

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).

Pulling into parking stall (brakes applied / traveling 5-10 MPH) the car lurched forward twice and stuck a parked full size truck. The car bounced backwards and lurched forward again and stuck the truck a second time and bounced backwards again. The ( off button) was able to be pushed at that time. The brake was fully applied the entire time. This has been the only occurrence. Infinity has not been able to duplicate problem and has downloaded the data base. The formal report will take approx. 4 weeks to complete. No parts have been replaced. Infinities consumer's affair has told us to pickup the vehicle and drive the vehicle despite no explanation or written proof the vehicle is safe to drive. The problem is related to either braking, acceleration or both.
