OK... all complaints aside; How much does a new precat set one back, -VS- waiting for your engine to fail and legal action to pay for it all? Sounds to me like those of us outside the shadow of misfortune could be better off relacing the pre-cat at 75K miles; to save all the anger & heartache.

JMHO.

I don't mind replacing the precat, but did you read all of the other stories? Sounds to me like the cat is positioned to close to the exhaust so I will continue having the same problem. What I need is a new engine, not another faulty part.

From what I've heard so far, if you don't have the problem yet then you should think about installing aftermarket headers, you should still pass emissions but you may fail the visual inspection, pay someone a little extra $ to look the other way. But you are at 75k so you are still within Nissan's 80k/8 year exhaust warranty, pay a Nissan dealer a hundred bucks or so to do some "preventative maintainance" and let them know you are aware and worried about this problem. I am at 75K and THIS MORNING I picked up my car from the dealer with a new (not rebuilt) 2.5 longblock and new pre-cat, free of any charges. If I were over 80K it would have been harder to accomplish but I've read about people prevailing under those circumstances as well.

It's a defective design, and it will eventually ruin your engine.

I argued with NNA, Submitted a complaint with both them and NTSH (?), and tried to get a law firm to take a suit against them. Even spoke to very talented mechanics.

Proving a hazardous design in a court of law, it beyond my budget.

Ok, THIS is why I drive a Honda Accord! Nearly 5 years as a tech with Nissan & Infiniti, and yet their engineering hasn't improved much. Was a Honda tech before and can tell you that they don't have those problems, just major A/C & Automatic Transmission issues! Take care, and next time, buy a friggin Honda! Especially if you can't afford the Cat repair!!

LOOK! Another Honda God has Spoken.

A simple header problem... or A/C & transmission problems... Folks; this is yet another confirmation from a "GOD TECH"... why I choose Nissan.
Good thing Nissan let you go. :loser:

PLEASE HELP THE CAR HAS BEEN @ DEALER OVER A MONTH

I need some help. I have been without my 03 Nissan Altima since 9/12/07. Initial I thought the problem was with the transmission so I took it the transmission place and when the tow truck came and tried to start the car it drove for two minutes and died. Keys were stuck in the ignition and the car was stuck in gear. Once i took the vehicle to the dealer they took a while to diagnose the problem as the Unified meter control and told me it was going to cost over $500 to fix. The problem is now THOUGH THE GRAPEVINES I AM HEARING THERE IS A NATIONAL BACKORDER FOR THE PART. Which means I have no idea when I am getting my car back and Nissan consumer affairs nor the dealer is helping me. I have over 75,000 miles on the car, I bought the car in 05 and I am still making car payments and I don't know what to do. PLEASE HELP ME

i hate nissan too...

I've replaced my engine, and then months ago, my car kept randomly turning off. Fortunately, I ran into good mechanics and recommended me to an Auto Electrician Specialist. They had a difficult time figuring it out... It turns out it wasn't the computer chip, it was the insulation of the wires to the chip. The insulation was so bad that it was causing random interference with the electrical signal, hence, my car/engine failing.

Unfortunatley, with dealerships, no one looks out for you or your best interests... You pretty much need to get really pissed off and start threatening with media exposure, etc. Get everything documented, everything. In the end you may at least have a chance at small claims and get your costs/expenses back.

i empathize with you. good luck.

The current Recall DOES NOT INCLUDE 2003

Hi ALL, Update on my Nissan Issue since 9/11 the car is still there, I ended up buying another vehicle but apparently there is nothing they can do for me because the recall did not affect the 2003 Altima. Unreal

Wholesale cost without tax from Nissan is about $390!!........even then, no guarantee the SAME problem won't happen again!! I've heard of the pre-cat going bad several times causing several motor replacements!

You can change the Cat a million times and the engine will still get ruined because it's the actual bad design of the whole system that causes it.

I'd LOVE to do away with the poorly designed, factory exhaust header/catalyst! What fix or modification do you recommend that will solve the problem AND won't cause the CEL (check engine light) to come on? I'm in NC and the CEL can't be on, otherwise it won't pass yearly inspection.

Thousands of owners have this problem

My research on the internet shows hundreds if not thousands of owners have this problem. It appears to be related to the catt converter buring up and junk getting back into the engine. MY daughter has the problem on her car and it has had perfect maintenance. Nissan claims they know nothing about it. Right!
We have filed a complaint with the gov and hope everyone else will. Maybe they can get Nissan to make this right. Engines shouldn't wear out at 50-60,000 miles.

IVOQ - File a Complaint

Here's the link. This is rediculous.

I feel your pain. I did submit a complaint to the NHTSA, but I never used that website you posted; so I submitted another one. Everyone needs to do it. Below is my description. My complaint list the Engine, & Exhaust.

"After replacing the oxygen sensor various times, I began to get huge amounts of oil consumption where I had to add every week. As a result the Catalytic Converter was shot, and also ruined the engine. During that period, my 2002 Altima had spontaneously shut down completely while operating on city roads and Interstate freeways. Despite having perfect maintenance and completing all recalls (see NHTS Recall Number: 03V084000 or Nissan Recall R3007), I had no choice but to replace the engine. The design is completely flawed and no recall will correct this bad design. "​

I just took my 03 altima in for excessive oil consumption w/ 70K on it.
They have the car and told me that the cat broke up and I need a new engine.
Said it is completely covered under some federal emissions law. I asked if it was completely free of charge and they said yes. Haven't gotten the car back yet, but wondered if anyone else knows if Nissan somehow wrangled this through the govt. Emissions law.
We'll see what happens when i pick it up.
Side note; got an 09 maxima as a loaner. Sweet car!

Hello. Do you have an update on this free repair? I am having the same issue with my 03 Altima - Dealer is not willing to replace ithe engine for free. Can you explain a bit more about what you had to do, say, demonstrate in order to get it replaced? I bought my car new. It now has 72,000, and I want to be able to convince the dealer and/or NNA to replace the engine for free beucase the Cat system is covered for 80K miles under federal law.

Research time for me! Any advise input you could offer would be awesome.

The dealership replaced the cat and the engine block, completely free of charge.
Originally, they said it was covered under the Federal emissions law, but when my wife picked the car up, they said they covered it under our 100K extended warranty.
I don't have the paperwork in front of me, but I will read it thoroughly and try to give you a more detailed explanation of the work.
I really didn't question anything, as I was just happy that they took care of it at no charge. As a side note, they did it fairly quickly. Dropped the car off on a Monday morning and it was done by Thursday afternoon.Considering they probably don't keep engine blocks in stock, I didn't think that was too bad.
This dealership has been good to me. Over the course of about 15 years,between me, my wife and my mother, we have bought 4 cars from them.
