2003 Nissan Sentra Problems
The electronic throttle actuator (throttle body) can fail causing a loss of power and illumination of the Check Engine Light.
The mass air flow (MAF) sensor can fail, causing various drivability problems. Our technicians remind us that proper diagnoses should be performed to confirm the cause of any driveability concerns.
The engine may stall at times due to a failed crankshaft position sensor and/or camshaft position sensor, These sensors can fail intermittently as they warm with the engine. Sensors on certain models have been recalled by Nissan and will be replaced as necessary. Please visit our recall section for this model to see if your vehicle is covered by this recall.
The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.

RepairPal Expert Overview:
The engine coolant temperature can vary at the coolant sensor due to its unique location. If these variations are large enough, a brief interruption in the signal output from the sensor may occur. If the signal interruption is so brief that the electronic control module (ECM) logic does not have time to diagnose the condition, the engine may stop running without warning. This condition will commonly occur only at low speeds. If the engine stalls without warning, a crash may result. Dealers will reprogram the ECM to correct this concern. The Nissan recall number is R0606.

95K 2003 GXE: Purchased in 2004 with 11 miles. CD Player stopped working after the first year. The exhaust pipe fell down and needed to be reattached (simple issue). No major issues until 2012. Replaced the Head Gasket, water pump, radiator, radiator hoses, serpentine belt, thermostat, and normal maintenance items within the last three months. Now the transmission is slipping. Great car until it dies. I wouldn't invest major work into this vehicle. Lesson learned.
The interior can use a bit more leg room. I have had to replace the struts twice in 7 years, but I guess that has a lot to do with the terrain you drive on. I love this car and will drive it until the cows come home.
I LOVE my car. I have had this car for 7 years and it has never given me a problem. Yes, I do the maintenance regularly like oil, filter and fluid changes which protect the internal parts. I also have taken my car directly to the dealership for service (except for oil changes which are cheaper elsewhere). The funny part is that my dealer's service dept is always cheaper by a good bit than the pricing on these sites. I just had my steering ball joints replaced. Repairpal estimate = $300 lowest price without an alignment. My dealer cost was $253 total including the alignment and both joints, parts and labor and taxes. I Love this dealer. They are doing it right!
