One problem related to engine failure has been reported for the 2009 Infiniti FX35. The most recently reported issues are listed below.
This vehicle randomly and suddenly has engine failure. This alone should really not be much of an issue except this advanced technology vehicle looses steering and brakes as soon as the engine quits. I have had 3 near misses with accidents as a result. The dealership is not able to find the problem even though there is a service bulletin out about this problem. There are no computer codes left behind to detect why the stalls are occurring. The only thing that has saved me is that the vehicle can be started again in neutral which restores steering and breaking power. It is a scarry and unsafe vehicle at this time and no body seems to be able to find a cure.
