I recently bought a brand new Nissan Altima 2007 2.5S. Soon after I bought it, I started to hear engine rattle at low speeds and during startup. I took the car in and I was told by the Nissan service department that it is a very common issue with Altima ’07 and ’08. They told me that they would fix it and allegedly did fix it but did they really???

Few days back, I started hearing the rattle again, the engine was too loud in the mornings during startup and I don’t think this is normal for a brand new car. I was thinking about taking the car back to the dealership but then thought I would wait until the oil change is due. But this morning, things changed, I received a mail from Nissan.

It talked about the same exact issue that I am having with my car. The stupid thing was, it said that we already did inform you about this before. No Sir! I was never informed, your service specialist said it was fixed the first time I took my car in and it wasn’t really fixed.

If you have a Nissan Altmia 2007-08 2.5SL, contact your dealer and find out when you can go to get the noise fixed. They obviously mention in the mail that only some drivers experienced it, yeah right. There won’t be this kind of an effort if only handful experienced this problem.

Nissan will install an exhaust stay bracket in your vehicle free of charge which would fix the rattle noise around the exhaust manifold heat shield. This noise supposedly doesn’t affect the engine…

    To Jeffrey Gagne–
    As per your last post saying…

    “I got fed up, as yesterday, when starting my car, the noise was unbelievably bad. I propped the car up on jacks and went to work. My heat shield near the cat was loose and I tightened them up myself. The problem that I notice is that when the car is cold, the heat shield shrinks causing the bolts to loosen, so, as to when the car is started, it rattles to a point of expanding from the heat, stopping the rattle noise. SO, if you want to resolve this problem once and for all, do it yourself. I hate to say it but the dealerships know nothing of what they are doing and I am logging a full complaint again the dealership and logging a complaint against Nissan as I finally resolved the problem myself. Any questions, let me know.”

    Jeffery–is this tightening of the heat shield something that you have to do over and over because of the expansion and contraction of the heat shield, or does tightening it up once solve the problem? Have you had any other problems? I am thinking about getting an ’09 Altima, but this blog is kind of a deterrent…thoughts after your experience?

    I owned an altima for under 5months before i trade it in for a mazda. I really like the altima but it was always making noises from the engine, being a girl that knows nothing about cars i felt the dealership was trying to tell me it was ok, when clearly it wasnt.

    I have an 08 Altima 2.5 SL. At first I loved the car and now I hate it. The noises are enough for me to consider another vehicle. I hear noises fromt the engine. A knocking noise when idle. The rattling noise from the rear. I’ve had enough. I think I’m just going to get something worth the money. Sometimes more expensive it the way to go. But with the enonomy the way it is I don’t know if that will be a smart idea !

    I have an altima 08 for about a year and a haft now and started to hear rattling noise. I’m not actually sure whether it’s coming from the engine or from the transmission but I can hear it at low speed i.e. below 40 (windows closed). The rattling noise is probably still there at higher speed but couldn’t hear it because of the louder engine sound. I’ve tried shifting the transmission manually to neutral during deceleration at low speed and still hear the same rattling noise. The rattling noise can only be heard while the car is in motion, when the car stops, the rattling noise also stops, when the car moves, the noise can be heard and as the car runs faster, the rattling noise sounds faster as well. Initially, the dealer thought that the noise is coming from the heat shield but after working on the heat shiled, the noise is still there. The dealer now says the noises coming from the CVT transmission which they are going to replace next week. Hopefully this would finally resolve the rattling noise problem.

    I have a 2008 Altima 2.5 Sedan SL. I have had nothing but problems with it from the first day I drove it home. Has anyone else experienced their car jerking upon acceleration and up to 45 – 50 MPH, lurching forward when barely pressing the gas pedal, vibrating at higher speeds or jumping forward when coming to a stop from higher speeds? I have experienced all of this plus more. I took the car in 3 times before the dealership acknowledged the popping noise in my heat shield, they finally replaced it. I've taken my car to 2 different dealerships several times complaining of how it drives but was told there was nothing wrong. Each time I got the car back however, it ran smoother, less jerking and better transition between the gears. I have even dealt with one of their regional technicians from Nissan who said they had a lot of complains about the CVT transmission and were working on a fix but didn't know when it would be available. So there contention is that there is nothing wrong with the car. I have contacted the BBB and hope to get some resolution that way. But from what I've been reading here, I know that I'm not alone.

    I own a 08 altima and have experianced jerking a hesitation for almost a year. I complained and the problem was looked at and acknoledged by the dealer. They even replace my transmission and it still did it. They sent a nissan tech out and he even admitted he felt the problem. He as well as nissan said there was nothing they could do. Then i contacted the bbb and filed a complaint. This did the trick. I had 3 engineers fly in from various states to look at my car. They worked on it for 3 days without success. Nissan contacted me 3 weeks later and is offering me a settlement of a new 2010 altima they would swap with me with no cost to me at all or they are going to buy back the car . In not sure what im going to do but this is what you have to do, put pressure on them and dont give up. Contact the bbb and fight until they make it right.

    07 Altima here! All thanks for this great info.  After 70k+ miles and 2 years, Nissan Corp finally acknowledged and fixed my ongoing break issues that started around the first 15k-20k miles.  The other issue that still remains unresolved is indeed the horrible rattle (sounds like a huge diesel truck/tractor) when starting up particularly in cold temps.  I’m a higher ed employee so I’ll have the next few weeks off for Christmas break.  I’m going to take it back to the dealer and ask them to keep it for a few days.  Since it seems to be related to low temps, it’s always bee hard to diagnose.  Any ideas, suggestions, before I make dealer contact again?

    I have a CVT tranmission in my 2007 altima. I just had the entire tranmission replaced at no cost to me. I had all the rattling noises…then it started jumping a little around 60 miles an hour…and when I pressed the gas. Finally last week my transmission completely failed. Nissan took care of everything including the rental car. I do like my altima…and now it drives better than it ever has. They verified the warranty on those has been extented to 120,000 miles or 10 years.

    I have an 2005 Maxima and I am hearing a clicking which I had diagnosed at my mechanic (not nissan) and he had the exact same car 2006 model that was knocking VERY loudly and said this is your future unless you can get nissan to fix it some how! THey should stand behind their work so me and my lawyer are going for it! I have already had the transmission rebuilt in this car too, NISSAN is on my shit list on the real!!!! Now from reading all this, Im scared that if Nissan does decide to stand behind their product and fix it that they wont do it right!?

    I had this problem once but recently upgraded to a newer nissan model which has worked flawlessly, better than nay previous car I have owned.

    I just bought a new 2010 nissan altima, and I noticed the rattling noise from the first time I started driving it. I took it to the dealer and they told me it is normal. I can’t remember exactly what he said, but it has something to do with antilock breaks. Since I don’t trust him, I went online and did a search and this page came up. Reading all these comments, I am guessing something is wrong with the car.

  • Abe

    I just bought a used ’08 altima 2.5s with 23,000 miles. After driving the car for 1 week, I started hearing rattling sounds coming from the interior front right side. This would happen every time I would go over any slight bump, usually under 40mph. I read online that the rattle is coming from the passenger door panel near the speaker. I drove the car with my friend and he discovered by opening the glove compartment, that the plastic map holder tabs were loose. He tapped them back in place and problem solved! I got the car certified and I am pretty impressed with how smooth the car drives and handles.

  • Mama

    I have a new 2010 nissan altima too…and most of the time at low speeds (up to 35 or 40 mph),it sounds like a diesel….but a rattle also at 1500 rpm’s. Never again will I test drive on a really hot day when the a/c is on HIGH,but it has gotten worse in the last month, and now I had my 1st oil change last week and it seems every more worse. They have “fixed” the problem twice but adding a exhaust clamp – NOT,and then told me I will experience the problem 10% of the time… well, I drive 30 miles of back roads traffic and an avg speed of 25 and I heard it about 75% of the time. Ready to schedule an appt. with the service manager to get in the car with me with I drive it… if you get in and push on the gas and get it passed 1500 rpms quickly, the sound is not that bad until you drop back down, but then again, I still think it just plans sounds like a diesel. And to make it worse, I’ve driven 4 other altima’s since I got mine…and guess what, no problems,no loud engine noise. I have also on 4 occasions had the “jump” when pulling on the gas – it pops so hard ahead, that my head hits the headrest. If I could of returned the car after 3 days I would of… I hoping Nissan will make it good soon and glad I have the 100K , zero co-payment warranty.

      I have the exact same problem with a used 2007 Altima I bought from the dealership two weeks ago! I love Nissans, but I am kinda dissappointed about this transaction. I keep hearing what sounds like a diesel engine! I just took it back to the dealership this morning…the acted like I was crazy and they didn’t hear the sound. Other than this problem I enjoy the car.

    I had the rattling sound on 2006 2.5 Altima SL since new. Replaced it with 2009. The same thing again. What drives me crazy is that Nissan dealer “never heard of this”. Hey, just Google and you will find 100s of complaints. So, don’t tell me that you did not hear about this problem!

       It’s a heat shield. Seriously. I own a 2008 with 102,000 miles, and the ONLY problem I’ve ever had was that noise during startup and cold takeoffs. I was about to take it tot he dealer, but then i decided to see if I could tackle it myself. There is was. loose bolts on the exhaust heat shield. Nothing to be alarmed about, but it was annoying.
