general problems of the 2009 Infiniti G37

Front passenger air bag occupancy sensor failure. Sensor is located on front passages seat and activates or deactivates passenger air bags based on occupancy and or weight. The vehicle has less than 90,000 miles. Passenger airbag/seat belt warning lamp on. Passenger airbag off indicator light remain on even when passenger seated. Repair cost estimated over $5,000. Vehicle will not pass inspection.

I am the original owner of this 2009 G37 sedan with only 12k miles. This car has never been in an accident. It is perfectly maintained and sits in a garage 99% of the time. Last week the airbag light flashed on. The dealer said the error code was b1018 (occupant classification sensor malfunction). The cost of the passenger seat cushion alone is $7,500. This problem was also found on the 2007 & 2008 G37 models and part of a NHTSA recall (#08v521000). I found this problem all over the internet and this NHTSA site for this model year G37. Please investigate this problem. Why isn't this part of the 2007/2008 recall when the sensor is bad in both instances?.

When it rains heavy water gets inside the car on both the drivers side and passengers side leaving the floor extremely wet. It is getting the wires wet. Many Infiniti owners are experiencing the same thing and believe inifiniti needs to make a recall.

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.

The passenger airbag light is blinking due to a faulty sensor contained in the passenger seat. If this light does not turn off, no airbags will deploy in the event of an accident, which is a huge safety issue. Infiniti charges more than $7000 to replace the sensor and the seat to fix this out of warranty. Infiniti refuses to do a recall for this issue which has been found to be very common in Nissan and Infiniti vehicles.

Airbag light is blinking so took to dealership charged $149. 00 and said they cleared codes. . . Service man said that something about passenger seat needed to be replaced for around $7000. 00. . . Light has come back on😬.

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.

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.

Apparently on 2009 Infiniti G37s, there is a programming error/deficiency in the electronic engine control module (ecm) affecting the processing of the mass flow rate sensor that will cause the engine to unexpectedly (and without a dash warning indicator) to lose power. At occurrence of the failure, the car will decelerate from highway speed to less than 35 mph within a few seconds. Following the failure, the engine rpm will not exceed 2,400 rpm and speeds above 35 mph are impossible (I found that 4th gear is the highest gear selectable). This failure can be dangerous in a number of traffic situations. I have learned from an Infiniti service dept. That the failure will temporarily correct itself if the engine is turned off for a period of time, but that the failure could reoccur. The car's ecm was re-programmed by towbin Infiniti (las vegas, nv) on August 30 and that supposedly fixes the failure. While at towbin, the service man said that Infiniti knows of the problem, but is waiting to see how wide-spread the problem is. Owners have not been told of this problem. Towbin service said they have seen about 300 cases of the problem. A salt lake city dealer service dept. Had also heard of this problem. Again, I feel this problem can be dangerous, because: if it were to occur in heavy traffic, it may be difficult to get out of the way of others; if it were to occur when turning in front of oncoming traffic; after it occurs, there is no way to keep up with higher speed traffic - one is left going slow and hoping no one rear ends me; without more information, I have no way of knowing if the problem has really been fixed.
