Nissan Altima Engine Failures

    I am experiencing the pre cat failure (pieces sucked into the motor) on my 2006 Nissan Altima. I am currently battling Nissan on denying my claim for them covering the cost of a new motor. Please follow me on Twitter to help make this a more public issue and hopefully get some resolution on not only my issue but others as well. Follow me @kafeend. Hope we can get something from Nissan other than the runaround.

    In my opinion this is something they should replace/repair at no cost to the consumer. It is an engineering/design flaw that they are aware of but take no accountability.

    Thank-You and I wish us the best. I have the extended warranty until August so I will be contacting them in the morning. So Here I go.....hope I get what I need, like a new engine.
    I do not have a twitter account so sorry but will try to keep this site up to date on the issue.

    Thank-You. I will be contacting my extended Warranty company in the morning and will let the site know what happens.
  • Yep. Just happened to me. Blown engine. Was told to call Nissan for possible replacement but they wanted us to pay for the tow and to have their mechanics to look at it. Therefore, their mechanics Decide what happened and of course Nissan would say their not responsible. Spending close to 400.00 for the tow(both ways) and the mechanics charge, I'm need some more information on this.

    Any futher progress on your car would be appreciated.

    They denied my claim as well. They stated that since I have 120,000 miles on the motor that they will not assist in replacement. I have been after them up until a few weeks ago. They blocked me from FB page and then stopped responding to twitter. We really need to try to get a class action lawsuit as this is unacceptable. Their engineering flaw (which they deny) is what is destroying motors not customer negligence.

    How enlightening! Let me give you my scenario, and you give me your opinion. I own a 2005 altima 3.5. Driving down interstate in left lane with cruise control set at 65. Car begins to speed up on flat straight road, all by itself, then suddenly begins to lose power. I turn off cruise control and step on gas peddle. Car still drops down to 40 mph. Finally begins to accelerate, but very if it is switching gears up and down. Was able to get off road without being killed. No light came on except for a very brief "slip" light. Had car towed to dealership. Dealership said they could not find a problem since no code shows up and they can not replicate what happened. My car only has 44,000 miles on it. Does this sound like the same problem everyone else is having. Should I contact headquarters to see if there are recalls (I've never received any), or should I wait to see if problem occurs again, or should I dump the car while it is still running?
  • The problem we were experiencing was only with the 2.5L engine... and nissan did do some recalls on that engine ....

    I'm having the same issue with my 07 Altima 2.5. In addition to that, now my AC has cut out, and if I get over 25 mph, the engine races and then my tire and key lights come on and the speedometer stops working until I come to a stop sign or red light. I'm not getting a check engine light and no error codes have been found but the car is not driveable like this.
  • i have a 2003 Nissan Altima which had the issue with the cadillic converter. I took it to a muffler shop and they were supposed to fix it.. well a year later going out of state for vacation driving the car it catches on fire... well had it take to shop and they said it was the cadillic converte. Be as broke as I am i took the whole exhaust off from headers to back exhaust. The first cat near the headers was already hollowed out... (i believe the muffler shop hollowed it out and painted it and called it done after paying them 500..) anyways i hallowed out the second one just to see if i could get it to run.. well it does... and works good.. then later that evening its taking for ever to build up power. I changed out spark plugs and did oil change. even bought new alt and battery for it
  • If there is a Autozone parts store you can get to... take the car there and have them "read the engine computer (ECM) for error codes" with their diagnostic tool... its a free service that they provide.. they can tell you what is going on with your engine.. before you waste more of your hard earned money buying parts that you dont need to replace ..
  • The exhaust system might have plugged up again. With the engine idleing, go to the back of the car and feel how much exhaust gas is coming out of each tailpipe. You should feel some warm gas blowing out on your hand. Then have someone in the car rev the engine up to 4,000 to 5,000 RPM while you are checking the flow of exhaust gas out the tailpipes. You should feel a rush of exhaust gas blowing out the tailpipe. If not you have a plugged or restricted exhaust system, which could be either of the CATs or the muffler. If you have had both CAT's cleared out, some of the CAT material could have blown back into the muffler and plugged the muffler. Once the exhaust system is opened up, it will run much better.
    What happened to me is that material from the first CAT broke loose and blew down to the 2nd CAT and plugged the second CAT. After I cleared it all out, it ran good.
    My first messege was #75, go back and read that and the ones after it to find out what to do.

  • I am currently having this problem with my 05 Altima, what was the outcome with your experience? Thanks
  • I have a 2003 Nissan Altima 2.5. I had the headlight bulbs replaced at the dealership and while it was there the dealership sideswiped something on the drivers side near the gas filler. I have begun to notice after driving the car and then parking it in the garage i can detect a strong smell of gas. I took it back to Nissan dealer and they put it up on the rack but could not see anything that would cause the fumes. They showed me that there was no work done around the filler neck and the charcoal canister was not flooded with gas but could not determine where the smell was coming from. They noticed that the fuel cap was not a OE one and said that could be it but wasen't sure. Well i haven't noticed the smell before i had it in the shop but i bought a new cap today but don't think that is the problem. Is there anything under the hood that might be causing this problem that they would have had to undo changing the bulbs? The car has 90,000 miles but just developed this problem. Any comment would be gratefully appreciated! Thanks
  • I have a 2003 Altima that had the precat die at 145,000 miles. Luckily, I caught it and after talking to the dealer I replaced it with an OEM replacement. then about 3000 miles later it did it again. Once again I got lucky on it and didn't suck any of the ceramic catalyst into the engine. Figured out after some research that the only real solution is to replace the precat with an aftermarket race header and install a test pipe on the number one O2 sensor. BTW, the reason that the exhaust can go backwards into the engine is that the EGR system on these engines is set up to hold the intake and exhaust valves open at the same time on the intake stroke for just a little while. Supposedly this makes the engine run cleaner by re-burning the exhaust. Of course the flip side is when the precat dies thanks to a bad design, some of the abrasive material can get pulled back into the engine.

    The EGR has nothing to do with valve timing. No exhaust is "reburned". The exact explanation is given in the messege that your replied to.
    "the pressure was high in the exhaust pipe all the way from the engine exhaust ports to the 2nd catalytic converter. This section of precatalyst/exhaust manifold and exhaust pipe has a volume and acts like a pressure tank holding high pressure when the engine is running, having higher pressure when the engine runs faster. So this is what happens, the exhaust coming out the engine exhaust ports is not a constant flow, as the exhaust valves are opening and closing very fast, so the gas comes out pulsating, pushing against the already high pressure in the precatalyst. At the END of a strong Exhaust Gas pulse, the high pressure in the precatalyst can actually push some gas BACK UP into the exhaust port, because of the high gas pressure in the precatalyst. So, the Exhaust gas is exhausting into high pressure, and some of the high pressure can PUSH BACK UP into the exhaust ports in between the high pressure pulses of exhaust gas coming out of the exhaust ports. Under "certain conditions" it is possible for material to blow from the precatalyst back into the engine causing engine damage.
    The problem doesn't seem to arise until there is backpressure in the system that can cause the precatalyst material to blow back into the engine."
    That is why this problem does not appear early in the engines life, but only after the milage is high(varies a lot). Only after the Catalytic Converter starts to clog the exhaust system and raise exhaust pressure at the outlet of the exhaust ports does this problem arise.

    I have a 2000 Altima, 96k, 2.5L 4 cylinder, and suspect I have a precat failure which previously caused a failed head gasket. Gasket was replaced and aluminum head was resurfaced. SES light was on prior to discovery of head gasket failure. SES light remains after replacement of head gasket. I'm not sure exactly when the gasket failed. Started it up one day and the parking lot turned into a cloud. So I suspect the precat has been bad for several months. Then head gasket failure. Now further symptoms of precat failure.

    (One question before continuing. I assume it is possible for the head gasket to blow even when temp gauge reads normal? Was it simply too much pressure?)

    Continuing... recently I have begun to have the poor acceleration/power problems often described as symptomatic of precat failure. I have driven it about three weeks under such conditions. I have finally looked into it. I will check oil level and consumption today. I have checked all fluids every week since symptoms began and all levels appear normal. I suspect I might dodge this problem if I eliminate the precat immediately? Am I on track here?

    Also, could someone provide a quick list of common Altima problems. So far: precat, intake manifold, sensors (which?), and head gasket. More specific? Anything else?

    Thanks so much. Especially electricdesign!

    Recently, I have same happen.. just engine stopped...Cant turn on the engine right away.
    I reserched from google. Mostly Cam and Crank shaft position sensor problem.
    I contact to nissan, this guy said I must dignostic and charge me $150.
    Iam thinking about buy the parts from autozone..
    Now ur altima is still ok? since changed cam and crank?
  • I have replaced my motor at 121,000 miles it was burning oil. Now arter 12,000 The motor has failed again. It had 121,000 miles on it when it was put in. I also have a p0340 code and my engine wont start. It has 90 psi compression. Is my motor bad?

    Why all the questions? This forum contains a wealth of information. It amazes me how people come on here and ask the same questions over and over, on subjects that have already been discussed to death here! All you have to do is go back and READ the previous posts in this forum. It is amazing, what you will learn if you start at the beginning and read through the whole thing, or use the search feature to find what you are looking for!

    And YES, you engine is shot. YOU especially need to read all the info in this forum.

    And the guy in the post above, the one who replaced his engine at 121,000 miles, YES, your engine is shot too! Was that a used or rebuilt engine that you put in? Either way, it's all junk. Get rid of the car and never buy another Nissan is the best advice I can give you.

    After I went through this NISSAN ALTIMA FIASCO in 2007 & 2008, I swore never again to have anything to do with ANY Nissan of ANY kind. I am now a happy TOYOTA driver, driving everywhere, all the time, having NO trouble whatsoever. All I do is put gas in it and drive & change oil when required, that's all, and I LOVE IT!

    Sorry for all you guys trouble, but buy a good car, and life will go so much better for you!

    I have code p0010 on my 2.5 altima how hard is it to get to actuator. Car stalls out occasionally ses is on now.
  • Actuator is near top of engine on timing cover on passenger side. The wire connector plugs in to the actuator solenoid from the backside. The computer sends a signal to this solenoid which then allows oil pressure to flow to the intake cam advance mechanism.

  • I am the latest casualty to the Nissan family. We bought a 2002 Altima about 6 months ago with 94K miles on it and just found out last month after I changed the oil myself back in August that the oil pan was bone dry. After doing my calculations the car burned through 1 qt. of oil every 300 miles. Certainly seems to tie into what everyone else is saying here. I wish I knew of this problem before I purchased the car otherwise I would have walked away. They previous owner knew I'm sure before he turned it over to the dealership. Oh well, I guess I will have to feed oil to this car until the engine dies. I called Nissan corporate and they play dumb to the whole thing like they are not aware of this situation.

    I haven't been here for over two years. I was checking to see if there was any new news about the Nissan Engine Problems caused by the Catalytic Converter being sucked into the 4 cylinder 2.5 L engines. I guess not, as these problems have died out as these engines bit the dust. It has been a very sad saga of our automotive industry and also a very sad saga for a government agency to NOT step in and make this right, and allowing a major Auto Manufacturer to screw over their innocent customers.
    I STRONGLY BESEECH all of you, in this day of computers and electronic technology, to PLEASE get on the INTERNET and research any vehicles that you are interested in, to find out any and all problems with them BEFORE you buy! DO NOT walk out on a car lot and shop for a vehicle according to how you :FEEL" or how it "LOOKS", or how much you "LIKE" it. Nothing wrong with liking your vehicle, but make sure it's a good reliable vehicle BEFORE you think about liking it.
    My first post on here was in October 2007, and then many more after that. If you are not too familiar with this problem, I would suggest that you go back to the begining of this thread and read through all the posts. You will find it very informative I'm sure.
    I hope this helps some of you.
