Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2005 Infiniti G35 owners, lightly cleaned up (personal details are redacted by NHTSA).
The fuel gauge is not reading correctly, and I have to rely on knowing my mileage and how much I last filled in my tank. I have to keep the car running longer than necessary to even duplicate the problem, and when I do the gas gauge just suddenly starts dropping. And if for some reason I even let my gas get low enough to have the low fuel lamp come on, it's almost too late and I barely make it to a gas station. I have not had the issue reproduced/confirmed by any independent servicer. I have seen in many G35 forums that this is an issue that has not had a recall yet. All of the other models for Nissan/Infiniti 2005 were recalled for the fuel sensor in 2010, but not the G35/G37 model. If this keeps happening I will eventually be involved in an accident when my gas runs out unexpectedly on the highway.
My car randomly shuts off when I'm driving. I actually ended up hitting the freeway divider. I need this problem fixed. I have been driving with the car turning off on me since January. The problem has gotten worse.
The car shuts down while driving and a combination of light such as slip and vdc appear. This has occurred 4 times in less than three years costing me 2500 in repairs. Each time the problem is diagnosed with a camshaft sensor issue. I researched online and there are hundreds of complaints listed from other Infiniti and Nissan owners. There certainly seems to be a pattern and this is a very dangerous situation as the car shuts down in the middle of a highway with traffic going 60 miles per hour and faster behind me. Since I am not breaking, the driver behind does not see a break light and could plow into me. I called Infiniti and they tell me there is no recall.
I was driving on the highway at 55 miles an hour when unexpectedly, the car starts to make some noise then it completely shuts down the motor, the check engine light comes on, vdc off, and slip lights all came on. I tried to restart the car, and only after multiple attempts (about three) did the car start. There is no warning. The auto repair facility ran a diagnostic and the code they got was the cam sensors needed replacing, which cost me $650. They said they have been replacing a lot of these. It's very prevalent. They informed me that the 2003 model of the Infiniti G35 had arecall for the same problem.
Tl* the contact owns a 2005 Infiniti G35. While driving approximately 5 MPH, the vehicle stalled and the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the camshaft position sensor needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and stated that the VIN was not included in NHTSA campaign number: 03V455000 (engine and engine cooling). The failure mileage was 115,000.
Driving car then it stalled. Tried to restart and all lights came on (engine, vcf, slip-light). Wouldn't start for 2 minutes. Once restarted, engine light stayed on. Drove car to get diagnostic test. Diagnostic says camshaft position sensor. Researched and found same happenings on 2002 & 2003 models; Infiniti has recall on those. Called about my VIN and Infiniti claims that my VIN is not included in recall.
While eating lunch at bojangles in petersburg, va., people inside the restaurant noticed smoke coming out of my car while parked. Fire department was called and fire was extinguished by a volunteer firefighter in area. Fire department arrived afterwards. It appears the seat caught fire unexpectedly. Interior of car also caught fire and was on burning until extinguished.
