What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

Vehicle experienced a minor grazing impact on both right side doors (in the middle of an intersection), which deployed the right side airbags and also the airbag inside the front passenger leather seat. After the accident, the window glass didn't break, the doors opened and closed normally. The safety issue is that when the airbags deployed, the engine died immediately, as if from an electrical failure, and the steering wheel pulled to the right and the driver (me) had no braking.

I am reporting a defect with the fx windshileds. They may have been misinstalled because today I noticed a 12" crack in my windshiled which started in the passenger side pillar. I have contacted infiniti and they said they are not aware of any issues with the fx windshiled. Yet on the infiniti website - [link removed] 12 fx owners have reported similar issues with the fx windshields. I would like infiniti to repace the windshield.

I own a 2003 infinity fx45 AWD. About june 2007 the steering wheel started to peel and breakdown and become sticky. So I put a wheel cover. Problem covered up. Thought nothing of it until about a month ago I noticed a crack on the dash in the corner by the speaker in the center of the dash. Then the next time I noticed a crack by the corner of the left dash speaker, then the next time the right dash speaker. Now I noticed a crack by the far right air conditioner vent on the dash.
