2003 Nissan Sentra Owner Comments

Car stalled out and was restarted and staled out again vehicle was driven to dealership and they found that one power valve screw had come out and that some others were loose. I paid the dealership to repair the vehicle but there is a recall for the same problems on the 2004 Sentra and up and Nissan is aware there is a problem with the 2002 and 2003 Sentra and Altima with the QR25 engine but will not cover the 02 or 03's with this recall.

On several occasions my 2003 Sentra ser would not start....on three occasions I replaced the battery and it would restart...on the 4th occasion I took the car to Nissan dealer here in harvey, la. Where it sat for 3 days and the service dept told me the car would now start.a fifth occasion occurred and by this time I had heard of a recall which I asked the dealer on phone about and he told me to bring car in so again I took car to dealer hoping to find problem...car sat there again for a few days after which it would start. They again told me no fault found was found and that they had performed recall...which they did not...it took me a couple of calls to service writer before he admitted it had not been touched. I read here of many Sentra S with same problems...you would think some one would know what is going on. My Sentra now runs terrible sometimes not starting and other times runs like it is running on 2 cylinders with a bad smell from exhaust. I am afraid of this car, but cannot afford to replace it.

Pre owed vehicle in excellent condition failed the state inspection due to a oxygen sensor defected causing the car to stop running and had problems starting the engine to run. Also affecting the panel showing the "service engine soon" comes and goes.

I own a 2003 Nissan Sentra SE-R spec V and while driving the engine shut off which could of caused me an accident and it restarted but didn't want to pickup speed. Had to get towed off the freeway and now does not want to restart. I had my daughter with me, which was very dangerous. Called Nissan and they said my car is not on the recall list, even though there is a recall for this year and model. Several mechanics told me that I need the engine replace, which is very expensive to which I cannot afford and my car is just sitting there.

I have an 03 Nissan Sentra, there is a problem with the cat converter, I have taken it to the Nissan dealer and they said the recall had been performed on my car, the car will still not pass my state emission testing and the engine has already been replaced once ( may of 08 ) due to losing oil and now the engine is blown again so I will again need a new engine.
