Engine became inoperable while driving causing a major safety issue. Several warning lights came on simultaneously (check engine light, slip light, vdc light) at the time. Car was able to be restarted with some trouble. Problem repeated itself (stalling, loss of power, starting difficulty) over next couple days, although warning lights never went off. Independent mechanic identified problem as cam position sensor failures & advised there was a the federal safety agency safety recall (the federal safety agency campaign id 03v455000) for the problem with 2003 g35s, but that my VIN was outside the campaign recall vins. He suggested I contacted infiniti. I contacted both dealer and infiniti national customer service who acknowledged there was a cam position sensor problem with 2003 g35s, but because my VIN was not in the campaign they refused to do anything to address the safety issue. I had my mechanic replace the cam position sensors at my expense (about $700). There are a number of similar complaints filed with the federal safety agency about this problem with no apparent resolution with infiniti. The recall campaign 03v455000 needs to be extended to cover all problem vehicles.

In april (2010) I noticed that my check engine light was on and my vehicle would not start. I waited and attempted to restart it a few times until it finally started. I went home and I planned on taking my car to the infiniti service center the next day. When I took my vehicle to the infinit service center I was told that my camshaft position sensor needed to replaced. I replaced it that day and then seven months later in november my vehicle began to replicate the same malfunctions. I thought it was my battery because I had just had this problem fixed. So I bought another battery, but my car continued to not start at random times. Therefore, I took my vehicle back up to the infiniti service center I was told that the camshaft position b2 went out. I had that replaced as well.
Tl* the contact owns a 2003 infiniti g35. The contact stated that he was unable to start the vehicle. The contact diagnosed that the cam shaft position sensor was defective and needed to be replaced. The manufacturer was made aware of the failure who did not offer any assistance since the vehicle was not included in the federal safety agency campaign id number: 03v455000 ( engine and engine cooling). The vehicle was not repaired. The failure and current mileage was 167,000. The VIN was not available.
Tl*the contact owns a 2003 infiniti g35. While driving 40 MPH the vehicle stalled without warning.

The contact was told that the vehicle should not be driven without the replacement, in which ne believed to be a severe safety issue. The failure and current mileage was 82,000. Updated 06/01/11
Vehicle would randomly stall out at 55 MPH+ and control of power steering is lost (battery light & vdc light would come on dash), no control of car. Many complaints on same issue.
Tl* the contact owns a 2003 infiniti g35 coupe. The contact was driving 50 MPH when the vehicle stalled without warning. After two to three attempts, the contact was able to restart the vehicle. The vehicle was not taken to the dealer for diagnostic testing or repairs. Neither the dealer nor the manufacturer was contacted. The failure mileage was 101,000.
Tl*the contact owns a 2003 infiniti g35. The contact stated that while driving 50 MPH, the vehicle stalled. The brake and service engine lights illuminated before the failure. The vehicle was taken to a local mechanic who informed the contact about recall 03v45500 (engine and engine cooling) related to the crank position sensor. The contact called the manufacturer who stated that the vehicle was not included. The current and failure mileages were 107,181.
The car is a 2003 infiniti g35. My wife was crossing an intersection when the car just stopped. Traffic coming the other way had to also stop to avoid an accident. She was able to start the car and get it going again, only for it to stop running one more time before getting home. I pulled the diagnostic codes from the car. It failed with a p0345 crankshaft position sensor a circuit bank 2. This sensor had a voluntary replacement from infiniti on the same year model car, except our VIN number falls just outside of the range. I truly believe that should be expanded, as this can cause a fatal accident should it fail at the wrong time. The car dies, which means you lose the power steering and brakes. I will replace the sensors as the dealer I spoke with would not cover it under the voluntary replacement due to the VIN not being covered. There are 4 of these sensors on this car so there is a potential for failure. Please look into getting the recall for this part expanded to cover all cars. There is too much at stake to not do that.
Today, I found 2003 infiniti g35 sedan leak oil into spark plug hole. Oil leak into the spark hole would cause engine fire with high voltage from ignition coils. I also found this issue was not limited to my vehicle but most of infiniti/nissan vehicles had this problem. I believe nissan already has known this issue. I hope the federal safety agency would do something for all of nissan/infiniti vehicle owners.

The vehicle wasn't repaired. The failure mileage was 137,000. The current mileage was 144,800.
Tl*the contact owns a 2003 infiniti g35 sedan. While driving approximately 40 MPH the vehicle stalled and the check engine, oil and battery service lights illuminated on the dashboard. Upon restarting the vehicle it would stall again within a few minutes. The vehicle was towed to an authorized dealer where it was in the process of being examined for the cause of failure. The manufacturer was notified and informed that his vehicle was not included in the recall associated with the federal safety agency campaign id number 03v455000, engine and engine cooling. The vehicle was not repaired. The failure and current mileages were 112,044.
Tl* the contact owns a 2003 infiniti g35. While the contact was driving approximately 35 MPH, with the air conditioner and radio activated, suddenly the air conditioner blower and radio became inoperable without warning.

The VIN was not included in the recall. The vehicle had not been repaired at the time of the complaint. The failure mileage was 93,000.
Vehicle would randomly stall out at 50 MPH+ and control of power steering would be lost (battery light & vdc light would come on dash), rendering the vehicle a dangerously fast moving lead sled. Power to the vehicle would resume after a few moments. Many trips to the dealership about this potentially deadly problem yielded no explanation or fix for the problem. After conducting my own research on the internet, it was finally determined to be caused by a malfunctioning crank shaft sensor. The sensor would get too hot and shut down, causing the loss of power to the vehicle. After a few seconds of cooling, power would resume. Apparently a tse bulletin was issued for this problem, but it did not include the VIN for my car since it was produced later in the model year. The sensor (a $40 cost part!) was replaced free of charge at the dealership only after putting up a fight. Infiniti/nissan needs to re-evaluate the scope of affected vehicles involved in this potentially deadly issue or be held responsible should someone die when their car stalls out at 65mph.
I was driving on the freeway and the car stopped. I had the car towed to a mechanic and he informed me that the cam shaft sensor and crank shaft sensor has gone bad. There was a nissan recall associated with this defect and they refuse to repair the defect.
Tl*the contact owns a 2003 infiniti g35. The contact stated the service engine warning light would illuminate on the dashboard and the engine would exhibit decreased power. The failure would occur intermittently over a two year period. The contact inquired with the manufacturer about the federal safety agency recall campaign id number: 03v455000 (engine and engine cooling) and was informed his VIN was not included in the recall. The vehicle was not repaired. The failure mileage was 95,000 and the current mileage was 125,000.
I have a 2003 infiniti g35 coupe with a cam angle sensor that went bad. There was a large batch of these issued for 620,000 vehicles, but not covered under my VIN. I was supplied with a faulty part that could put my life at risk in the event the car shuts off on the highway.
Tl*the contact owns a 2003 infiniti g35 sedan. While driving 20 MPH the check engine light illuminated on the instrument panel then the vehicle stalled. After repeated attempts the vehicle restarted and operated normally. The vehicle was taken to an authorized dealer the following day who stated that the bank one position crank shaft sensor needed to be replaced. The vehicle was not repaired. The failure continued to recur intermittently. The vehicle was taken to an authorized dealer again who replaced the bank one position crank shift sensor. The failure mileage was 124,000 and the current mileage was 126,000.
I just bought a used 2003 infiniti g35 a few months ago. I believe I am the fourth owner. It has run immaculate until the last couple weeks. For some reason the air conditioning system takes itself into auto mode and the radio lights go out, along with the rest of the lights on the panel that control the AC functions. I cannot use any of those buttons to change anything. The radio continues to work and I can still use the steering wheel controls to adjust the radio, but I can no longer see the lights that tell what station it's on nor adjust anything from the panel. The AC goes out of manual mode into auto mode, which if I understand it correctly, auto is a normal function, adjusting itself to maintain whatever temperature you have it set at, but the fact that I cannot change it back to manual mode, nor anything else on my own after it goes in that mode, and turns out the panel lights, makes me think this is not right. Thank god it is defaulting to on as it is summertime and over 90 degrees outside, but still gets very cold and is loud at full blast. However, if this were winter months, this would be a safety issue as there would be no way to defrost my windows and obviously cause serious discomfort in having freezing cold air blow on you in the middle of winter. I have seen several other complaints/technical services bulletins about this on mycarstats.com and wonder if there is already a recall on this. Some folks have stated something about a voluntary recall relating to the circuit board... Others have stated a voluntary recall for the equipment relating to this but only included the recall on certain VIN numbers. I haven't yet called the manufacturer, which I will do, but am hoping that this is covered by the manufacturer as in my opinion it is a safety concern and has been complained about by several infiniti owners.
Tl* the contact owns a 2003 infiniti g35. The contact stated that while stopped at a traffic stop, the vehicle abnormally accelerated and then stalled. All warning lights on the dashboard were illuminated. She was able to restart the vehicle and resumed traveling at speeds of 75 MPH when the vehicle stalled a second time. The vehicle was towed to her place of residence and the manufacturer was contacted. She was advised that there were no recalls on her specific vehicle and that any repairs would be at her expense. The vehicle was not repaired. The current and failure mileages were approximately 94,000.
I was driving on the road and my car lost all power. My camshaft position sensor had to be replaced, but the dealer said it was not covered under the recall campaign 03v45500 which was for this exact problem.
There is an apparent known defect in the 2003 infiniti g35 models. The radio and climate control will apparently lose all indicators, as if there is no power, but will continue to function, staying frozen on at their last settings. The radio volume or channels cannot be changed and the air conditioning/heater,etc. Are stuck on their last settings and cannot be changed without turning the car off. This is caused by a defective control board behind the dash. Infiniti/nissan is aware of the problem, and has issued a voluntary service campaign (# itb03-007b) to repair the 26,300 vehicles listed by VIN # on the service bulletin. This is a hazard , as in the winter, the front or rear defrosters cannot be turned on, or the air conditioning turned off, causing a hazardous driving condition. Infiniti says my 2003 VIN # does not fall into the bulletin parameters, (VIN # is higher), and they will not cover the repairs, even though it is the same problem. Infiniti states the cost to repair.........$2600.00. It is apparent that the bulletin did not go far enough to cover this defect on a larger quantity of vehicles than infiniti wants to admit.
1 week ago I've noticed a sudden degrade in performance. The car is providing 1/2 as much power as usual, but no warning lights or gauges revealed anything. Inspected obvious things like fuel, oil level and purity. 2 days ago *vehicle for the first time suddenly stalled while driving, and was hard to start again. It took almost 1 minute to restart. Check engine light activated. Car continued to be hard to start after instances that it was shut off. Last night: *vehicle stalled again while driving on the freeway, during my delivery of the vehicle to the dealership to investigate this issue. This is a very dangerous problem, I'm lucky no one crashed into me.
Tl* the contact owns a 2003 infiniti g35. While traveling at speeds of 65 MPH, the check engine, brake, vdc and spin indicator warning lights illuminated on the warning panel. The engine stalled and all power was lost. The contact was able to maneuver the vehicle off the of the road and restart the engine within moments. An independent mechanic inspected the vehicle and advised the contact that an authorized dealer should diagnose the failure. The dealer advised the contact that vehicle was included in the federal safety agency campaign id number 03v455000 (engine and engine cooling). The vehicle had not been repaired. The current mileage was 98,937 and the failure mileage was 98,923.
My 2003 infiniti g35 sedan experiences intermittent failure of the control panel for operation of the A/C, radio, etc. Because of this electrical problem, the engine throttle is unable to be reset. It idles at 1000 RPM and does not reduce rpms when slowing or stopping the vehicle. This causes a shaking of the vehicle. While this make, model, and year vehicle do appear on a recall list, the VIN number is out of range so the dealer will not repair the vehicle.
2003 infiniti g35 coupe- loss of engine power while driving followed by "slip" and vrc warning lights coming on. The car just suddenly stopped on the freeway. Good thing it's a manual tranmission and I could coast to the side. I was lucky not to get into an accident . Tests reveal both cam sensors need to be replaced. I have seen numerous reports like this yet no recall is being produced. This is almost as bad as the toyota accelaration problem.
