Two weeks ago whenever my max had an indicated quarter tank of fuel in it or less, the engine would hesitate. It would cut out like it was hitting the rev limiter under moderate accleration or if the rpm's were 3.5k or higher. As the fuel gauge went down the hesitation problems increased. There were no check engine lights when the problem was occuring. My max is four years and four months old and has 94,450 miles.

The cause of the engine hesitation was a failed fuel sender unit. When the dealership checked inside the gas tank they said it had almost no gas in it. The engine's hesitation was from fuel starvation. The low fuel light never came on. Typically the low fuel light on my max comes on when I have 3 to 4 gallons of fuel left. The fuel gauge was incorrect and not giving me a true indication of how much fuel was in the tank.

I got my max back from the dealership with the fuel gauge on E with no low fuel light. When I was driving my max home I was relieved that my max did not have the hesitation problems it did before. I filled the gas tank as soon as possible and it held 13.5 gallons so it appears that the low fuel light was correct in not coming on.

Before I had this problem the fuel gauge would take forever to drop from full to 3/4 tank and then drop quickly from 1/4 tank to E. Now the fuel gauge drops from full to 3/4 tank quickly and is slow from dropping from 1/4 tank to E. Go figure. I am keeping a keen eye on mpg just to be safe.

Now to the bad part. It took almost two weeks for the dealership to get my max back to me !!!! Four days to diagnose the problem and another week to get the parts. The worst part was that I had to drive a POS loaner which was a 12-year old Honda Accord! I find it unacceptable that the dealership took that long to diagnose the problem. Having to wait a week for the parts is Nissans fault. The total damage for this repair was $250.00.

I think it has been taking longer for them to get their parts shipments.

Where is the fuel sender unit located? under teh hood, or towards the back of the car? thanks...

The fuel sender unit is located inside the gas tank. Fuel sender unit sounds like a fancy name for a fuel pump if you ask me, but I am not sure of that. The fuel sender unit cost $100 and $10 for an o-ring.
