2004 Infiniti M45: check engine light

Filed Feb 24, 2012 · Fuel system · 112,000 miles · NJ

Hello, I own a 2004 infinity m45 and I wish to file a complaint. My gas gauge doesn't function properly and it reads half full at empty which caused my wife to stall out at night!!!!! On the highway!!!!! I thought it may have been just my car at first until I googled it realizing there are thousands of identical incidents. My check engine light is also on reading p0461 faulty fuel sensor. I hope someone can get infinity to fix this situation seeing its obvious that this is a manufacturing issue...thanks for your time in advance...

Purchased a 2004 infiniti m45 with 76k in may 2010. Within 2 days of buying the car the check engine light came on. I had it scanned and it said "fuel sending unit" so I replaced that part and the light went off. About 2 days later, the gas tank was about 1/4 tank shown, and I watched the fuel gauge needle move from 1/4 tank to "full" at the stop light. Shortly thereafter the check engine light came back on. I did a quick "google" search and found multiple online forums discussing this topic and the real fault is the gauge cluster. I contacted a local infiniti dealer and asked about the problem and was told "it's only happened a few times" but I had pages of other owners posting on the forums saying it had happened to them. The dealer told me it would be $800 to replace the gauge cluster, so I said "no thanks" and had my original cluster repaired with a lifetime warranty at bba remanufacturing and it has worked perfectly since september 2010. Prior to repairing the original one, I purchased a brand new gauge cluster on ebay, but it was not for my model with icc and nav, so I have spent money buying a gauge cluster and repairing my original one.

This car died on me on the highway when the fuel gauge said that I had a 3/4 tank of gas remaining. The car started sputtering like it had run out of gas so we added gas and it started right up. I drove it to a local infiniti dealership right away. They diagnosed the problem as in instrument cluster, which shocked me as I have never heard of an instrument cluster being responsible for a car running out of gas. I searched some online forums only to discover that there were hundreds of other people who had the same problem. Had the fuel sending unit or furl pump went out, that would be understandable, but the instrument cluster going bad could have been very dangerous. Since the cluster controls mileage and all the warning lights such as check engine lights, this was very scary. It seems that infiniti knows there is a problem with these as many of the people on the forums said infiniti had paid for a new instrument cluster. With this problem being so prevalent, I think it is very important for the federal safety agency to look into. I believe it should be a recall with the number of people having problems. Although my issue happened around 90,000 miles, there were many others that experienced the problem at 30 and 40,000 miles.

This complaint relates to a 2004 infinity m45. In the summer of 2009, I noticed that the fuel gauge was showing nearly a full tank of gas, but I that was incorrect because I had not put any gasoline in it in over 3 days. The next day as I was traveling over a very busy bridge in tampa, fl, my vehicle sputtered to a stop. Since that time, the fuel gauge has not worked correctly. Shortly after that time the "check engine" light illuminated. I took my vehicle to be checked out and was advised that the repair would cost in excess of $1,000.00. My vehicle was just outside of the 60,000 mile warranty so I went online to infiniti's website to seek assistance but never got a reply after numerous attempts and pleas for assistance. One would think that a manufacturer such as infiniti would take better care of it's customers. After not receiving a reply a reply online, I contacted my local infiniti dealer and was pretty much told I was on my own with getting my vehicle repaired and offered no assistance. As of the time of my complaint, my vehicle has 86,543 miles on it. This is why I'm filing this complaint!

This complaint relates to a 2004 infinity m45. In the spring of 2010, I noticed that the fuel gauge was showing nearly a full tank of gas, but it had been a long period of time before I had put gas in the tank. When I filled up the tank, I realized that the tank was nearly empty. Since that time, the fuel gauge has not worked. Shortly after that time the "check engine" light illuminated. I've taken the vehicle to the dealership several times. They have replaced several sensors. Finally, they concluded that the instrument cluster is bad and needs to be replaced, a costly repair. Running out of fuel on a busy interstate is a danger, and something that must be fixed. Moreover, the vehicle will not pass state inspection with an illuminated "check engine" light. After noticing several similar complaints related to this make and model of vehicle, I called infiniti to see if they would help with the repairs. The vehicle is outside of warranty, and infiniti refused to offer any assistance. This was disappointing. I would have thought that a luxury car manufacturer, like infiniti, would agree to repair or replace a defective sensor cluster that obviously suffers from a design or manufacturing defect. As a result of the safety issue associated with the defective sensors, and infiniti's refusal to voluntarily assist in the repair or replacement, I am filing this complaint.
