Air bags

54 reports4 crashes1 fire1 related recall
“B1022 OCCUPANT SENS C/U [COMM FAIL] - CURRENT B1022 OCCUPANT SENS C/U [COMM FAIL] - PAST Passenger seat Air Bag: There is a recall on this part for my vehicle's year make and model, but my VIN shows my car isn't apart of the recall.”

Electrical system

23 reports3 fires
“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.”

Power train

21 reports1 crash
“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.”

Structure

17 reports
“The Suspension Subframe Crossmember (Front) Part Number: 544B2-EG300 Supersession(s): 544B2EG300 Fits Infiniti G35’s (2007-2009) Have issues where it starts to rust on all areas of it . This includes the joints of the cross member and support areas. The rusting that occurs definitely impacts the structural integrity of the part and it can very well be a safety issue and a fatality waiting to occur . The cost of replacing this part may vary , as prices range from $473.00 +tax to $937.00 + tax not including labor cost that associates with the getting this unit replaced .”

Engine

16 reports1 fire
“Runaway acceleration. Three times now in the last two weeks the RPMs went to maximum redline without my foot on the accelerator pedal. Fortunately all occurred when I was at very slow speed and either in a driveway or a parking lot. Each time I immediately put the transmission to neutral and shut off the engine. For the first occurrence, Restarting the engine all went back to normal. But for the second instance, two weeks later on restart the engine again instantly went to maximum RPM (deep redline). On a second restart, with additional delay before attempting a restart, the problem cleared. I took the car to a mechanic and they said no error diagnostics were recorded. On test drive he said he noticed some brief unexpected surges. He said for liability reasons no way he would work on the car. No warnings, no instrument indications, car does not seem to "know" throttle is at max redline.”
