“Car's fuel gauge indicated nearly 1/2 tank of fuel remaining when tank is completely empty. I found out the hard way -- was driving, made a right turn onto a busy road, hit the gas and the engine died. If this had happened on I-75, particularly the 20+ mile stretch that's under construction and has no shoulders, this probably would have resulted in a major accident.”
NHTSA complaint #10353972, filed 2010-09, 117,500 miles“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. …”
