Four problems related to body have been reported for the 2003 Infiniti G35. The most recently reported issues are listed below.
The car won't back up when it's on reverse, sometimes it won't move at all even when it's on drive.
My slip light and vct light has came on in my 2003 Infiniti G35 and also the ebrake light and non of them will go offf. I recently hydro planed in the rain due not being able to turn my traction control on abs did nothing to stop my car from loosing traction this would never of happened if my car did not have these problems. Further looking into it they have had made a TSB talking about how the abs and anti wheel lock may malfunction. I was in a 5 car pile up and almost died. If my traction control was able to be turned on witch it wouldn't let me I would not of hydro planed my whole back end just swung forward out of nowhere people though someone in my car pulled my ebrake the way the back end just swung forward. Both the slip light and the vct light remained on along with my ebrake light. I drive my car like a baby and to barley push the gas should not result in my back end swinging forward resulting in completely wreching my car along with 4 other drivers. I feel Infiniti is definitely reliable and should of recalled these parts due to putting people in danger instead of making it a TSB like its not a big deal. I am also not the only one iv found a few people that crashed there car due to rainy wether and the traction control not wanting to turn on. I was on the freeway doing about 60 to 65. If I new Infiniti had so many problems I would not of purchased one 77 bulletins and after reading about all the problems the 2003 had and all the recalled parts I would not of purchased it and put my life at risk. I feel Infiniti should be reliable it's commen sense to know that first hand not fixing those problems would lead to serious injuries and I'm not the only one. Let me know what you think I will be emailing Infiniti to. It may not be a recalled part but it' put me and everyone else on the freeway at risk and totaled my car. Bellow is someone who also had the issue.
The radio will turn off by itself and turn back on a few seconds later. All of the buttons in the center console become inoperable. The a/c controls also become inoperable and turns on by itself. It just doesn't turn on though, it turns on 90 degrees and starts blasting out. This is a safely issue because as a driver we never know when this air is just going to start blasting out at us like fire. If Infiniti is Smart enough to recall the sedan, they should do the same thing with the coupes. It is clearly a common problem among the '03-'04 models. If they want to keep their reputable name they will do what is right.
The rear upper quarter panels show signs of flexing, the body appears to have minor dent like ripples from where the rear window pillar meets the rear quarter panel. In the beginning, I thought it was just a minor issue, however as time progress, the body flexing is appearing more and more.
