2003 Nissan Sentra Problems

What owners report

Owner complaints about this model year center on engine stalling and long or failed starts, most often traced by mechanics to the crank or cam position sensor, and on a separate pattern of oil consumption and catalytic converter trouble on 2.5L cars. Electrical faults such as a dead instrument cluster, check-engine light codes and ECM communication problems are the second most common theme, and noisier electrics are reported at moderate mileage. Many complaints were filed between about 40,000 and 130,000 miles.

   Engine cooling

   Engine stalls or will not start (crank/cam sensor)

   • 90 complaints (50%)
   • median 72,500 mi at 6.4 yrs old (80 state mileage)
   • 4 mention a crash, fire or injury
   • owner-quoted repair $1,639 (median of 6 quotes)
   • filed 2003–2022

   Complaints describe the engine shutting off while driving, sometimes at highway speed and sometimes at traffic lights, often with the check engine light on before or after. Restarts are inconsistent, and some cars crank for a long time or need repeated attempts. Mechanics and dealers cited in the complaints frequently point to the crankshaft or camshaft position sensor; several owners say their vehicle identification number was not covered by the related campaigns, so the work was paid for out of pocket. Reported across a wide mileage range, from a few thousand to over 130,000 miles, with many reports between roughly 40,000 and 100,000 miles.

   What to check: Ask for service records showing whether the crank and cam position sensors were replaced and with which part, and note any long cranking or intermittent check-engine light on a cold start and during a test drive.

   “Check engine light has been on for a while with erratic gauges that only work sometimes.... Then recently car has been shutting off, completely dying while driving sometimes at low speeds, sometimes on the highway. Sometimes will restart for me, sometimes will not. After research online, found out about recall on 03 sentras with the exact things that my car has been doing. …”

   “2003 Nissan Sentra engine quit and check engine light came on. Would not start. Nissan had a recall 03v455000 but my VIN is not included in the recall even though it is a 2003 Nissan Sentra. I had to pay for the repair- around $280.00 out of pocket.”

   Engine

   Oil consumption, converter debris and engine damage (2.5L)

   Mentioned in 9 of 60 sampled complaints

   Owners of the 2.5L cars describe oil disappearing quickly, sometimes a quart every day or two, along with a sluggish engine and heavy noise. Several complaints say debris from a failing catalytic converter was drawn into the engine and that the result was low compression, scored cylinders and ultimately an engine replacement. Dealers in some accounts first called the oil use normal, and later diagnostics confirmed converter and engine work. Mostly reported between about 55,000 and 130,000 miles, often after the emissions warranty had expired.

   1 related service bulletin

   What to check: Check the oil level and look and smell for a fuel or burnt smell, ask whether the front converter was replaced, and have a compression or leak-down test done before buying a 2.5L car with unknown history.

   “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.”

   NHTSA complaint #10285195, filed 2009-09, 96,000 miles

   “I have a 2003 Nissan Sentra ser. From day 1, I have had issue after issue..I am the only owner of the vehicle. Upon many repairs under warranty, one of them was for the ECM, years later the same issue has come back. I contacted Nissan and the dealer about this and they will not help me because they state that they already fixed it with the recall. But they did not. A certified mechanic has determined the issue with the vehicle. It is not even safe at this point to drive. …”

   Electrical system

   Instrument cluster and check-engine light faults

   Mentioned in 9 of 60 sampled complaints

   Complaints describe gauges that bounce, drop out or read erratically, and instrument cluster backlighting that fails while the car keeps running. Many also report the check-engine light coming on with assorted codes, sometimes with hesitation or stalling, and mechanics proposing ECM replacement or reprogramming. A few owners say shops could not reproduce or locate the fault. Reported mostly from about 33,000 to 135,000 miles, often appearing intermittently rather than at one mileage.

   Recall 03V4770003 related service bulletins

   What to check: Watch the gauges and warning lights during a drive, ask for any stored code list, and ask whether the ECM has been reprogrammed or replaced.

   2 excerpts from owner complaints in NHTSA records

   “1. The car dies out while driving -suddenly all the gauges become erratic and engine dies out. Service engine soon light comes on. Bouncing gauges occur while driving. 2. Service engine soon light comes on every 3-4 months. The car dies out while driving once a year. Bouncing gauges occur at least once a month -erratic and sporadic. Because of this ongoing problems that the dealer has never been able to fix, it gives me great emotional distress and fear of driving. It was pure luck that I did not get into accidents so far. …”

   Fuel system

   Long cranking and hard starting

   • 40 complaints (22%)
   • median 70,459 mi at 6.2 yrs old (37 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $700 (median of 5 quotes)
   • filed 2004–2018

   Owners report the engine cranking for several seconds or needing several attempts before it fires, sometimes with a rough idle and a check-engine light. Complaints mention fuel pump replacement under warranty that did not hold, fuel level sensor circuit codes and ECM reprogramming. Some say a dealer initially found nothing wrong. Often reported in the 17,000 to 70,000 mile range, with a few at much lower mileage.

   2 related service bulletins

   What to check: Start the car from cold and time the crank, ask whether the fuel pump or level sensor was replaced, and check for emission-related reprogramming records.

   2 excerpts from owner complaints in NHTSA records

   “My car started to have a very long cranking period when starting the back in 6/2007, took the car to dealership they nothing was wrong. I took my car to the same dealership three time between 6/2007 and 10/2007 and everytime they said there was nothing wrong with the car. In 11/2007 I took the car to another dealership and they said it was the fuel pump, they replaced it under warranty. A year later in 11/2008 the started having the same issue and once again they fixed the issue, now in 3/2009 the car is having the same issue again. …”

   Air bags

   Passenger air bag inflator recall not completed

   Mentioned in 4 of 60 sampled complaints

   Several owners describe being unsure whether the passenger air bag inflator recall applies to their car, or being told a prior inspection did not include replacement of the inflator. Complaints also note that seat trim changes or prior service can affect air bag operation, so owners ask for confirmation of status. Reported as questions about recall status at high mileage, from about 100,000 miles upward.

   “- the contact called regarding the 2003 Nissan Sentra. The driver was traveling at 45-50 MPH when the engine suddenly shut off,and the vehicle continued to move.

Buying note. On this model year, budget for an ignition sensor and electrical sorting on top of the purchase, get records for the air bag inflator recall work, and have the engine checked for oil consumption and converter condition, especially on the 2.5L cars.
