2003 Nissan Maxima Problems
The Camshaft position sensor can leak oil into its electrical connector causing the Check Engine light to illuminate. The engine may also stall intermittently as a result.
The ground inside mass air flow (MAF) sensor can corrode and possibly cause drivability problems. The corrosion is enough to affect the sensor data but not enough to create a trouble code. Diagnosing this can be difficult because it won't always illuminate the Check Engine Light.
The thermostat may become stuck closed, causing an overheating condition. Replacement of the thermostat will be required to correct this concern.
Problems with the ignition coil will cause the vehicle to misfire or not start.
2003 Nissan Maxima Recalls (Recent)
RepairPal Expert Overview:
Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.

2003 Nissan Maxima Reviews
This car was purchased in october, '12 with 178k miles on it. I had never owned a nissan(car or truck) in all my 32 years of driving but, I'd heard so much about this maxima's V6 engine(voted best engine 8 years in a row)that I thought I make the change from Toyota---most reliable cars and trucks I've owned to date.
It being used with so many miles on it, i figured a few maintenance issues might need attention, but I didn't expect so much at one time. In these three months, I've replaced the spark plugs, brakes and rotors, interior/exterior lightbulbs, oil and air filters, and made some cosmetic improvements.
However, the car still needs new shocks, theirs an oil leak, and makes a rub sound each time I turn left for the 1st time after starting the car. I have to stop and restart the car again for it to make that sound again after turning left and it won't make it again while being drivin.
The '03 Toyota Tundra, V6/5-speed, also has 168k miles on it but all I've done to it is regular maintenance since buying it at 32k miles. It's been the best vehicle I've owned to date in terms of reliability and low upkeep. But the Maxima is the most fun to drive I've owned.
I hope that after I've 'bought it up to speed on maintanence, it will provide me with another 200k miles of trouble-free driving, but as of now the jury is still out. My only regret is not buying a maxima with less miles on it or that was upkept better. Other than that it is a the best looking car and has an engine that purrs and I can't wait to take a trip to California in it.
Old Maxine has been very reliable but the milage is getting up there, so major services are due.Just replaced the OEM radiator .All motor mounts are worn out at the point so thats going to cost.Engine still runs strong and everything works.
