“While driving my 2004 Infiniti G35 sedan with 6 speed manaul on the highway- I suddenly got a vdc slip slight, service engine soon light. The car began to sputter intermittingly loosing power. I was able to make it to the side of the road and ultimately into a parking lot - although I was nearly rear ended when the car stumbled. This happened one before in sept. 2007 with my wife - in which the dealer replaced the cam sensor.”

“Nissan just started a recall for stalled engine. My car (2004 infinti G35) seems to do the exact same thing but it is not part of the recall and I took it to the dealer but they said there was no problem with the car. Now, the engine stalls once in a while and you have turn the car off and restart for it to work. I called Infiniti and they said can not do anything right now because it is not part of the specific recall. The car poses safety issue if it is to stall in the middle of highway, it will threaten safety of others including myself.”

“Engine started to smoke at start up's on my 2004 G35. Had vehicle for about a year. Took vehicle to Infiniti dealer to have problem corrected. Infinite would not repair stating that there was engine slug build up. Took vehicle to an independent mechanic to have second opinion. Mechanic found no slug build-up under oil cap nor in crankcase. I contacted Infiniti consumer affairs to stress my complaint. No satisfactions or resolution to my complaint. Infiniti has a poor warranty on their vehicles. …”
