NHTSA's VIN data lists no trims for the 2006 Frontier, so these are the versions EPA tested, by its names. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 617 complaints with NHTSA about the 2006 Frontier. 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 4 recall campaigns for the 2006 Frontier 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 IS RECALLING CERTAIN MODEL YEAR 2004-2006 ARMADA, TITAN, INFINITI QX56 AND MODEL YEAR 2005-2006 FRONTIER, PATHFINDER AND XTERRA VEHICLES. THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) ASSEMBLY CONTAINS AN ENGINE CONTROL MODULE (ECM) RELAY THAT HAS A DIODE FOR ELECTRICAL CURRENT NOISE REDUCTION. THE ECM RELAY MAY ALLOW SILICON VAPOR TO FORM AND, OVER TIME, THE SILICON EVAPORATES FROM THE DIODE MOLDING WHICH CAUSES SILICON OXIDE TO DEVELOP ON THE ECM RELAY CONTACT DUE TO ARCING.
Risk: THIS COULD CAUSE ENGINE STALLING INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE ECM RELAY INSIDE THE IPDM ASSEMBLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 6, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
NISSAN IS RECALLING CERTAIN MODEL YEAR 2006 AND MODEL YEAR 2008 FRONTIER, XTERRA AND PATHFINDER VEHICLES. THE MOLDED FUEL TANK SHELLS CAN DEFORM, CAUSING THE FUEL SENDER FLOAT ARM TO CONTACT AN EMBOSSMENT MOLDED INTO THE TANK SHELL CAUSING THE INSTRUMENT PANEL FUEL GAUGE TO SHOW THAT THE VEHICLE HAS APPROXIMATELY ONE QUARTER TANK WHEN THE FUEL TANK IS EMPTY.
Risk: THIS COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL IN TRAFFIC, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE FUEL LEVEL SENDING UNIT INSIDE THE FUEL TANK WITH A NEW ONE THAT HAS A MODIFIED FLOAT ARM. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE MARCH 22, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
NISSAN IS RECALLING 242,720 MY 2005-2009 PATHFINDER, FRONTIER AND XTERRA VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA. IN THOSE AREAS OF THE COUNTRY WHICH USE HEAVY CONCENTRATIONS OF ROAD SALT IN THE WINTER, A MIXTURE OF SNOW/WATER AND SALT CAN ENTER INTO THE FRONT CRASH ZONE SENSOR (CZS) HOUSING. IF THIS OCCURS, THE CZS MAY INTERNALLY RUST RESULTING IN A SIGNAL INTERRUPTION. IF THIS HAPPENS, THE RED AIR BAG WARNING LIGHT WILL ILLUMINATE TO ALERT THE VEHICLE OPERATOR.
Risk: THIS ISSUE COULD RESULT IN THE NON-DEPLOYMENT OF THE DRIVER AND PASSENGER FRONT AIR BAGS IN A CRASH, INCREASING THE RISK OF PERSONAL INJURY.
Remedy: DEALERS WILL REPLACE THE FRONT CZS WITH A REDESIGNED SENSOR. THE RECALL BEGAN ON JANUARY 26, 2009. OWNERS IN THE OTHER STATES WILL RECEIVE EXTENDED WARRANTY COVERAGE FOR THE SENSOR TO 10 YEARS. THESE OWNERS WILL BE NOTIFIED OF THE WARRANTY EXTENSION BY MAIL AND WILL RECEIVE A STICKER TO PLACE IN THEIR WARRANTY BOOKLET EXPLAINING THE EXTENDED WARRANTY COVERAGE. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
ON CERTAIN KING CAB TRUCKS, IN A SEVERE SIDE IMPACT CRASH, THERE IS A POSSIBILITY THAT DEFORMATION OF THE VEHICLE'S BODY COULD CAUSE THE FUEL FILLER CAP TETHER TO BE STRETCHED TO THE POINT OF UNSCREWING THE FUEL FILLER CAP.
Risk: THIS MAY RESULT IN A FUEL SPILL WHICH IN THE PRESENCE OF AN IGNITION SOURCE COULD RESULT IN A FIRE.
Remedy: DEALERS WILL REPLACE THE FUEL CAP TETHER PIN ASSEMBLY WITH A MODIFIED ONE FREE OF CHARGE. THE RECALL BEGAN ON APRIL 24, 2006. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

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.
