Air bags
12 reports3 related recalls
“The red airbag light on the instrument panel IS on. I have taken the car to the infinity dealer and they say a sensor is out and would be $800 to $1000 to repair. It seems the airbag system should be warranted as long as the car is registered. The mfg book says if this light is on the airbag may inflate, not inflate when needed, just not work. I am concerned, I do not want the bag to inflate as I or my wife is driving. This not a very good safety system if can go out from just one sensor it seems it should have a redundant system for this.This is a safety issue that seems infinity should have to fix especially with the problem with airbags. I do not want my wife or I to be a statistic for a bad airbag system.”

“ENGINE STOPPED RUNNING WITHOUT WARNING. LOST ALL POWER WHILE DRIVING ON THE ROAD. SERVICE ENGINE LIGHT SOON CAME ON ALONG WITH SEVERAL OTHER WARNING LIGHTS, ENGINE WOULD NOT RESTART READILY AND THEN STALLED AGAIN WITHOUT WARNING. HAD TO HAVE THE CAR TOWED FROM THE ROAD FOR REPAIR. THE CAM SHAFT SENSOR AND CRANKSHAFT SENSORS WERE REPLACED. THIS IS THE EXACT SAME REPAIR CONDUCTED UNDER THE RECALL 03V455000 FOR INFINITI I35S FOR 2002 AND 2003. OBVIOUSLY THIS PROBLEM CONTINUED IN CARS PRODUCED IN EARLY 2004.”
