2004 Nissan Maxima Si 3.5L from Australia and New Zealand
It's an OK car
FYI: This car is 70% RENAULT, I think. Apart from the engine which is Japanese, I believe everything else was done by Renault.
1. Recall on all the door actuators - driver's door locked up and would not open up at all. Had to get in from the passenger side.
2. Alternator recall; second time lucky.
3. The fuel gauge is playing up. Dealer told me to leave it alone as repairing this could cost me big bucks.
4. Now there is a weird engine noise when I start the car cold. The noise goes away in 5 seconds.
The car drives good, but is guzzling fuel now.
Now it does more like 14L / 100km, maybe because I am only doing short distances everyday; more like 2km / day.
I will be neutral on this review, as most of the issues mentioned above were replaced under manufacturer recall.
Would you buy another car from this manufacturer? Don't Know

Your poor fuel consumption is definitely affected by your driving distance. 2km is not enough for the engine temperature to warm up enough to send a signal to the ECU and run the fuel system in closed-loop mode. That means that until the car is warmed up enough, the ECU will run the engine rich so as to comply with emissions regulations. I had a similar temperature problem with an older Audi - bad fuel consumption. I read somewhere about the open-loop operation due to a thermostat stuck open (so it wouldn't warm up). I changed my thermostat, the consumption improved dramatically. The car will only start running in closed-loop mode when the engine has reached proper operating temperature. So if you drive 10 km, and it takes say 2 km for the engine to get warm, it will guzzle fuel for those two km and get more economical for the rest.
