Owners have filed 116 complaints with NHTSA about the 2006 Sentra. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 5 recall campaigns for the 2006 Sentra over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Nissan North America, Inc. (Nissan) is recalling certain 2002-2006 Sentra vehicles whose passenger air bags were previously inspected and may have been released without replacing the Takata air bag inflator. In the event of a crash, Takata frontal passenger air bag inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Owners are advised not to drive their vehicles until the repair has been completed. Nissan will notify owners, and dealers will re-inspect the vehicle and, if necessary, replace the air bag inflator, free of charge. The recall began January 22, 2021. Owners may contact Nissan customer service at 1-800-867-7669. Nissan's number for this recall is PM964.
Nissan North America, Inc. (Nissan) is recalling certain 2001-2003 Maxima, 2002-2006 Sentra, 2002-2004 Pathfinder, 2007-2011 Versa Sedan and Versa Hatchback, 2001-2004 Infiniti I30 and I35, 2002-2003 Inifiniti QX4, 2003-2008 Infiniti FX35 and FX45 and 2006-2010 M35 and M45 vehicles. The vehicles are equipped with non-desiccated, frontal passenger air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Nissan will notify owners, and dealers will replace the front passenger air bag inflators with alternate desiccated inflators, free of charge. The recall began February 12, 2020. Owners may contact Nissan customer service at 888-737-9511 or Infiniti customer service at 888-810-3715.
Nissan North America, Inc. (Nissan) is recalling certain model year 2001-2003 Nissan Maxima, 2002-2004 Pathfinder, 2002-2006 Sentra, 2002-2003 Infiniti QX4 and I35, 2003 FX35 and FX45, and 2001 I30 vehicles. Upon deployment of the passenger side frontal air bag, excessive internal pressure may cause the inflator to rupture.
Risk: In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
Remedy: Nissan will notify owners, and dealers will replace the passenger air bag inflator, free of charge. The recall began on June 15, 2015. Owners may contact Nissan customer service at 1-800-647-7261. Note: On December 18, 2015 Nissan informed NHTSA of an amendment of this recall to remove 2004-2005 Infiniti FX35 and FX45 vehicles.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A 2.5L ENGINE, THE CRANKSHAFT POSITION SENSOR CAN OVERHEAT CAUSING A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR.
Risk: IF THE INTERRUPTION IN THE SIGNAL FROM THE CRANKSHAFT POSITION SENSOR 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 WHILE THE VEHICLE IS DRIVEN AT A LOW SPEED INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPROGRAM THE ECM FREE OF CHARGE. CERTAIN MY 2006 ALTIMAS WHICH HAVE BEEN PREVIOUSLY REMEDIED UNDER RECALL CAMPAIGN 06V223 (NISSAN R0606) ARE NOT INCLUDED IN THIS RECALL SINCE THE REPROGRAMMING FOR 06V223 ALSO INCLUDED THIS REPROGRAMMING. THE RECALL BEGAN ON DECEMBER 31, 2007. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
CERTAIN PASSENGER VEHICLES EQUIPPED WITH 2.5L ENGINES MAY EXPERIENCE EXCESSIVE ENGINE OIL CONSUMPTION AS A RESULT OF IMPROPER PERFORMANCE OF THE PISTON RINGS.
Risk: IF THE OIL IS NOT MAINTAINED AT LEAST AT THE MINIMUM LEVEL, ENGINE DAMAGE CAN OCCUR AND IN EXTREME CASES RESULT IN AN ENGINE FIRE.
Remedy: DEALERS WILL REPROGRAM THE ELECTRONIC CONTROL MODULE (ECM OR ENGINE COMPUTER). YOUR VEHICLE WILL ALSO BE INSPECTED TO DETERMINE IF IT HAS BEEN CONSUMING ENGINE OIL AT A HIGHER THAN NORMAL RATE. IN A SMALL PERCENTAGE OF VEHICLES, ENGINE REPLACEMENT WILL BE NEEDED. ON JUNE 9, 2006, NISSAN NOTIFIED OWNERS OF THE POSSIBILITY OF EXCESSIVE OIL CONSUMPTION AND THE IMPORTANCE OF MAINTAINING THE OIL AT A PROPER LEVEL. FOLLOW-UP LETTER TO OWNERS ADVISING THEM OF THE STATUS OF THE RECALL WAS SENT DURING AUGUST 2006. FOLLOWUP LETTER TO OWNERS WAS SENT ON NOVEMBER 15, 2006. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
Carmakers sent NHTSA 63 service bulletins and notices that cover the 2006 Sentra, the latest on Apr 13, 2026. They tell dealers how to fix known issues.
The parts they mention most: electrical system (13), engine and engine cooling (8), equipment (8), air bags (5), service brakes (5).
NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
