The contact stated that there was a complete loss of power. The contact coasted the vehicle to the side of the road and was able to restart the vehicle. On another occasion, the contact stated that the engine indicator illuminated and "check your fuel cap" displayed on the instrument panel. A dealer and the manufacturer were not made aware of the failures. The contact cited the federal safety agency campaign number: 03v455000 (engine and engine cooling) as a possible cause of the failures, as reported by a code reader.

While I was driving this vehicle, it had shut off while I was driving and I lost all power. It started back up like normal. This has happened twice and I'm afraid this could happen while I'm on the highway with my family. I see there was a recall involving this but not for my vehicle. This has happened to me just recently.

While leaving an entrance ramp to merge onto the interstate, the vehicle suffered a complete and total engine power loss along with its power steering and power braking functions. After this failure, the vehicle would crank but not start, leaving it stranded. There is currently a recall in place for the vehicle's make, model, and model year (recall #03v455000), however I was told by both the dealership and infiniti that the vehicle was not covered under that recall because the part in question was made by a different manufacturer than what was included under the existing recall. The summary and consequences of this failure align exactly with that of the existing recall. It is evident that the safety hazard exists beyond the scope of the original recall and the purpose of this complaint is to address that deficiency.

I was traveling down I-85 n bound doing about 65 in the middle lane with heavy traffic when the RPM dropped all the way out and the car lost all power as if it cut off leaving me in shock because I had no way of getting over to get off on the shoulder.after taking it to a shop I was told that it was the cam and crankshaft position sensors and that I need to contact infiniti before paying to have this issue fixed because it was a recall for this issue, so I contact the infiniti dealer and the lady I spoke with informed me that it has never been a recall for any issue on this car and that since the car was 10 years old that was a possible problem with the car shutting down while operating the vehicle,.

This vehicle randomly will shut down all mechanical systems simultaneously at any speed which creates an extremely dangerous situation, especially around other traffic, which could result in a crash. The car's "service engine soon" light appears, the car immediately loses engine power, brakes, and steering and many times will not restart immediately which puts the passengers at risk of a crash in any situation. These are the exact same symptoms of a recall issued by infiniti for the 2003 m45, however, infiniti insists that this vehicle is not included in the recall. Maybe once someone is killed in a crash infiniti will reconsider its position on this matter. According to the infiniti dealer, they do not know the cause of the problem. Their suggestion was to leave the car with them for 2 or 3 days so they could hook up equipment to the car and drive it around (at $130 per hour) hoping that the problem would occur. Both the dealer and infiniti USA seem unwilling to investigate this problem without costing me hundreds or even thousands of dollars to fund their research in an effort to prevent a crash. Here is the description of the symptoms caused by the recall: this could cause the "service engine soon" warning light to come on, create a no start condition, cause reduced engine power, or cause the engine to stop running without warning during vehicle operation, which could result in a crash.

On the freeway with the wife, at ~60 MPH, the engine stalls, characteristics very similar to recall. Had to put into neutral and restart car on the fly to avoid a major accident. Since then it has happened two more times, luckily while at a stop. Contacted infinity and was told that the VIN on my car was not affected by the recall, although I have the exact same issues. (even a camshaft sensor code popped up since and have had an issue turning the engine from a cold start once already). My car also suffers from the infamous fuel gauge issue which infiniti doesn't even have a recall for yet. See recall from infiniti/nissan below: engine and engine cooling recall date: nov 17, 2003 model affected: 2003 infiniti m45 summary: on certain passenger vehicles, the circuit board for the crank position sensor or cam position sensor may have an improper solder joint due to solder deformation caused by heat stress accelerated by the existence of flux residue during the soldering process. Consequences: this could cause the "service engine soon" warning light to come on, create a no start condition, cause reduced engine power, or cause the engine to stop running without warning during vehicle operation, which could result in a crash. Remedy: dealers will replace the crank position sensors. Camshaft position sensor(s), and in some cases, the variable timing control sensor(s). Vehicles involved in a previous recall campaign, 01v357, are also included in this new campaign. The replacement sensors used in that campaign are also affected. Owner notification began on december 22, 2003. Owners should contact nissan at 1‑800‑647‑7261 or infiniti at 1‑800‑662‑6200. Potential units affected: 630000 notes: nissan north america, inc.

Fuel gauge level indicator stays at much higher level than is actually present. Mostly stays at full reading, but sometimes goes to half level when in actuality the fuel level is close to empty. For the most part, it stays at full level indication and sometimes causes an intermittent "service engine soon" light to appear on the dash cluster assembly. After having the obd2 error code read, it states that the fuel sending unit is faulty, however after having it tested, the fuel sending unit is working within normal specifications. After much research, it is believed that the fuel gauge itself is faulty and a replacement of the cluster assembly is recommended to remedy this specific issue. When this first happened, I almost ran out of fuel on the freeway.I felt power loss while cruising at highway speeds. Fortunately, there was a gas station coming up at the closest oncoming exit and I was able to make it in and refuel. That is when I discovered that I had an issue with this fuel gauge and decided to research this. I have found this has been a problem for many owners of this specific infiniti model vehicle.
