Selected complaints filed with NHTSA by 2004 Infiniti G35 owners, lightly cleaned up (personal details are redacted by NHTSA).
I was driving my car and heard a loud sound and then my airbags went off. I lost control on my steering and was able to coast the car to shoulder. The airbags deployed even though there was no collision with another car. Under further inspecting it looks as if all the bolts came loose on the drive Trane. I have no idea why the airbags went off. I did sustain an minor injury to my hand. police were called, fire trucks checked for possible fire hazards. I looked for recalls and or air bag malfuctions for this year make and model but did not find any. Had I not been in the far right lane I could have been in a serious accident. The airbags deploying scared me. Both the driver and passenger side airbags went off. I was the only one in the vehicle.
The car burned nearly 4.2. Qts of oil in under 4000 miles. Massive number of users indicate same problem of insane amounts of oil consumption on various forums on the internet. This is most likely also a serious smog violation in ca and also is causing engines to blow up. Numerous mechanics will verify that they have seen the same problem with engines blowing at under 100,00 miles do to excess oil consumption. I have proof of my last oil change and number of miles. Also the amount of oil that came out of my car was less than a quarter of quart after only 4,000 miles of driving. My mechanic verified that there are no leaks. Please NHTSA! Please investigate this issue further. 20,0000 dollar car is basically totaled now. All dealers and Nissan refuses to acknowledge the problem even though there is a high possibility they know of the problem and are hiding it. …
While driving our 2004 infinity G35 on the fwy going about 40 MPH (the ground was wet) we felt the track control started to shift side to side, a truck cut in fron us us, which made my husband put on brakes, as he putted on brakes, the driver side front brake locked, which caused for the card to turn sideways and hit the center divider full speed. The brakes after they locked, never stopped the car, the only thing that stopped us was the center divider. The airbags never pop, as we hit the wall going 40 miles per hours. I have taken the car to the dealer recently and had the brakes changed (2 times in 11 months) and the last tme I tood the car I informed the dealer that the brakes felt hard, and they were hard to stop they stated that the brakes will get better with use, and that's how it usually felt after the brakes were changed. …
On August 30, 2007, I was stopped at a red light in my 2004 Infiniti g35x and was struck from behind while stationary with my foot on the brake. The vehicle that struck me was traveling at a high rate of speed estimated to be in excess of 40mph. The impact crushed my rear bumper and trunk and drove my vehicle into the rear of the SUV stopped in front of me, crushing my front end and inducing deployment of the passenger air bag although there was no one occupying the passenger seat. However, the driver's side air bag did not deploy in this collision, and while the seat belt restrained me, my arm hit the steering wheel, and I suffered musculoskeletal injuries in this accident. The car has been deemed a total loss. Both the insurance appraiser and I have questioned whether a defect prevented the driver's side airbag from deploying. I have reported the incident to Infiniti.

I was traveling at 35 MPH and I was hit by another car in the driver side door and I slipped straight about 100 feet and hit a light pole none of my airbags deployed and my foot was on the brake the whole time and it seemed the bakes did not perform as expected.
I'm astoundingly concerned about the safety of this vehicle. This is the second 2004 G35 I've owned and the first one I purchased brand new, owned 9 years, drove 230,000 miles and had none of these issues/failures when it was sold to a happy new owner ... Although it was a g35x. This is how I know these are in fact failures/defects in this second one. This vehicle has not experienced any recent damage or known problems, yet the last few days every time it has been started, the airbag light is remaining lit for an extended period of time before it decides to go off on the dash. It lingers and then finally goes out. It has been very rainy and humid here for an extended period and we are a state targeted for Takata recall, but this vehicle is "not one" allegedly. I fear for my safety! …
The third brake light on the rear deck has failed for no apparent reason. The car will not pass inspection. They want several hundred dollars to replace the entire unit. I have researched online and found this is a voluminous problem for this model year. It was recalled and addressed by Infiniti for the 2003 model year g and it is still a problem for the 2004 year. This needs to be recalled and fixed accordingly at the manufacturer cost. All these owners are not having the same failing issues without cause. I own two 2004 Infiniti G35 sedans. I used to love both of them. This one has problems with the brake light and now the airbag light is mysteriously blinking for no reason! The other one has had issues for years with being able to put gas in and I have had problems at the gas station trying to fill the car! Ridiculous! If Infiniti doesn't do something ... I'll be switching makers. …
