INTRODUCTIONNissan has determined that some 2002-2003 model year Altima and 2002-2004 model yeaiSentra vehicles equipped with the 2.5 liter engine have defects that relate to motor vehiclesafety. For 2002-2003 model year Altimas, there is a possibility that the exhaust pipehanger pin may catch debris from the road that could be ignited by contact with the catalyticconverter and cause a fire. In addition, for 2002-2003 model year Altimas and 2002-2004model year Sentras, there is a possibility that certain engine operating conditions maycause damage to the pre-catalyst. Material from inside a damaged pre-catalyst could enterthe engine and result in increased oil consumption. If the engine oil level is not checked ona periodic basis and drops below the low level, and the driver continues to operate thevehicle ignoring noticeable engine noise, engine damage may occur which could result in afire.

NUMBER OF VEHICLES POTENTIALLY AFFECTEDThe number of vehicles potentially affected is approximately 360,000. OVERVIEW OF REPAIRExhaust Pipe Hanger Pin:• The exhaust pipe hanger pin is shortened on 2002-03 Altimas, except those that werealready repaired. This repair is NOT necessary on Sentra vehicles.ECM Reprogramminq / Pre-Catalvst / Exhaust Heat Shields:

• ECM reprogramming is required to prevent future damage to the pre-catalyst. A specialreprogramming card is available that contains ECM reprogramming data for allmodels/engine/transmission configurations affected by this campaign.

• The exhaust pre-catalyst will be tested to determine if the pre-catalyst needs to bereplaced.

• The exhaust pre-catalyst will be inspected to determine if more extensive repairs areneeded, that, for a limited number of vehicles, may include engine replacement.

• Installation of Heat Shields on the exhaust system is required.Use the "Repair Flow Chart" in the Service Procedure to determine the complete repairprocedures for a specific vehicle.

SPECIAL CUSTOMER ASSISTANCE FEATURES

Customers should be informed that: A. The basic repair for this campaign should take approximately 3 hours to complete.

B. A limited number of vehicles affected by this campaign may require more extensive campaign repairs.

INFORMATION REGARDING ENGINE & EXHAUST SYSTEM MODIFICATION(s)

Some vehicles may be presented for repair that have been modified using non-Nissancomponents or in a way not authorized by Nissan. Vehicles that have minor or cosmeticmodifications (such as a modified air filter/intake system) will be eligible for this campaign,as long as the modifications do not affect the dealer's ability to diagnose and install thecampaign parts in accordance with this bulletin within the allotted time(s).Owners of vehicles with more extensive, non-Nissan approved engine and/or exhaustsystem modifications may be responsible for bringing the vehicle into a condition thatallows the campaign procedures to be followed and the repairs completed. Extensivemodifications to these systems may make diagnosis (an essential part of this campaign)and the installation of campaign parts not possible. In such cases, the engine/vehicle mustbe returned to an appropriate condition in order for the campaign repair to be performed.For example, the following Original Equipment Manufacturer (OEM) parts must be installedand functional: • all oxygen sensors • the pre-catalytic converter • catalytic converter • engine (ECM) control moduleOnce the campaign repair is completed, the re-installation of any non-Nissan parts is thefinancial responsibility of the owner and the cost to install these parts must be negotiatedbetween the dealer and the vehicle owner. The Nissan dealer may elect not to perform anyrepairs that may violate emissions or other regulations.

this is what you will recieve from the dealer telling you about it.

OWNER'S LETTER (vehicles with exhaust pipe hanger pin)Dear Nissan owner:This notice is sent to you in accordance with the requirements of the National Traffic and MotorVehicle Safety Act. Nissan has decided that a defect that relates to motor vehicle safety exists in some 2002-2003 model year Nissan Altima vehicles equipped with the 2.5 liter engine.

Reason for RecallThere is a possibility that the exhaust pipe hanger pin may catch debris from the road that could be ignited by contact with the catalytic converter and cause a fire. In addition, there is a possibility that certain engine operating conditions may cause damage to the pre-catalyst. Material from inside a damaged pre-catalyst could enter the engine and result in increased oil consumption. If the engineoil level is not checked on a periodic basis and drops below the low level, and the driver continues to operate the vehicle ignoring noticeable engine noise, engine damage may occur which could result in a fire.

What Nissan Will DoIn order to prevent these incidents from occurring, your Nissan dealer will shorten the exhaust pipe hanger pin. The dealer will also reprogram the electronic control module to prevent any future damage to the pre-catalyst. In addition, the dealer will install heat shields on certain components of the exhaust system on vehicles that do not already have them. This free service should take about three hours to complete, but your Nissan dealer may require your vehicle for a longer period of time based upon the dealer's work schedule.The pre-catalyst will be tested to ensure it is working properly and replaced if necessary. If damage is found inside the pre-catalyst, it will be necessary to replace the engine. Nissan anticipates that few engines will need to be replaced. If the engine needs to be replaced, this also will be free of charge and will take several days. In this case, a car rental allowance is available from your Nissan dealer upon request.

NOTE: If the engine or exhaust system of your vehicle has been modified with non-Nissan parts orin a way not authorized by Nissan, you may be responsible for bringing the vehicle into a condition that allows the campaign diagnostic procedures to be followed and the repairs completed. If it is not possible to properly test the pre-catalyst and install all of the campaign parts, you will have to pay the cost to return the vehicle to an appropriate condition in order for the dealer to perform the campaign repairs. You may also have to pay to add any modifications back to your vehicle.

What You Should DoContact your Nissan dealer at your earliest convenience in order to arrange an appointment to have your vehicle repaired. Until then, check engine oil regularly and fill as needed. If you notice excessive engine noise or an abnormal odor from the engine compartment, you should stopdriving and contact your Nissan dealer to arrange to have the vehicle towed to the dealer forrepair. Please bring this notice with you when you keep your service appointment. Instructionshave been sent to your Nissan dealer.

realy? cause i heard the EXACT (word for word) same recall a while back, that had to be atleats 3 or 4 months ago, i also heard a problem of the cat thats coupled to the header becoming too hot and catching fire

Scott:

Thanks for the scoop!

Fred..:thumbup

fred, do u remember seeing a previous post about the same recall? either that or im having serious de ja vou, cause i couldve sworn ive seen teh exact same recall on these forums

im with nlzmo here. i saw the same thing posted here not too long ago like maybe earlier this year. your not crazy man dont worry.

find the link. I have been with nissan for 8 yrs. I knew approximatly 1 month prior to the recall it was coming but it was very hush hush with nissan so if it got on this site it had to of come from someone in NNA. Now there was a concern with the oil consumption problem for a good year or so before but nissan was not running a recall for that. this condition with the cat may have been related to the oil consumtion problem on some vehicles but was not discovered till about 6 months prior to its release. Research and development took place during the six months to find the cause and the last month lay out of the recall was performed. but if you can find the post you are refeering to that discusses the cat problem and the reprogramm of the ecm I will retract this statement.

Scott

retracted!!! now I need to find out where he got this info
