What 2008 Infiniti G37 owners say
Air bags all 21 →
The contact owns a 2008 Infiniti G37. The contact stated that while driving at various speeds, the air bag warning light flashed intermittently. The vehicle was taken to the dealer, where it was diagnosed, and determined that the Occupant Classification System (OCS) varistor in the front passenger seat had failed and needed to be replaced. The vehicle was not repaired due to the cost. The contact related the failure to the Manufacturer Recall Number: P8243. The manufacturer was made aware of the failure; however, no assistance was offered. The failure mileage was approximately 140,000.
The airbag control module can be damaged through normal use. Simply disconnecting the battery can damage the module, which then causes the airbag malfunction light on the instrument cluster to turn on. It is unclear weather or not the airbag will function when this occurs. Presumably, it will not. The dealer solution for this is to replace the module, at a cost of over $1000. Fortunately, it is possible to remove the module and send it to a 3rd party who can reflash a chip. However, doing this every time a random electrical glitch (common ) causes the warning system to trip is dangerous.

Around 6 am on 4/13/19 me and my family and neighbors were awoken by an explosion in the front end of my vehicle..we called the fire dept and they ruled it as an electrical problem..I noticed that all the sensor lights in the dash would blink and the airbag sensor light was going off that evening prior to the incident..I didnt think much of it..I was planning on taking it to a mechanic that morning but it caught on fire..its a total loss.the fire fighters had to cut the hood open in half to get to the fire in the engine compartment..its not fair..I had just bought that car..and I loved my infinity..luckily I wasnt injured or anyone else. The vehicle was parked in the street..I need my car for work , school and on a regular basis. Please help me.
Transmission & drivetrain
After 60K miles, the car has difficulty shifting in reverse. Once in reverse, the car doesn't roll back and it remains idle as if left in park. A foreign transmission repair shop owner said that this issue is not user error, and that Nissan/Infiniti have not been having ongoing trans issues with many of their models, but refuse to claim responsibility for most. Nissan/Infiniti USA will easily goad customers into paying $8K to install a new trans, however.
Driving the car in parking lot at work, placed car in reverse as the clutch was being released the car stalled out and shut off. The clutch bottomed out to the floor board and remained there. Car was unable to be driven. Was towed to auto shop to find out the slave cylinder requires to be changed.
