One problem related to engine stall has been reported for the 2008 Infiniti G35. The most recently reported issues are listed below.
I recently purchased this car from a Nissan dealership and it happened on the first and second day owning it. The first day happened when I pulled into the gas station taxing to the gas pump and all the sudden, the steering wheel started to get harden. I looked at the rpm gauge and it was down to zero while I was in "d" mode. So shifted to park and restart the engine, then it works again. The second incident happened when I was at a stop sign turning right. Immediately after releasing the brake pedal, I turned the steering wheel and the engine stalled; therefore, the steering wheel was harden. Then I shift back to park and restart again. I'm not sure if this is common to any G35x but this is a safety issue. I do not want to image myself going into a round-about and the car stalls while other car coming toward me. Please look into this.
