I just bought my 2010 3.5SR March 13th and from day one I've noticed upon starting the car and backing from my parking space then shifting to drive it will make a clunk, sometimes a twang sound when first starting out. I'd venture to say this isnt normal. I'm not pushing the pedal down hard at all, but I've begun to think maybe I'm not pushing it down enough, but theres no need to open it up in the parking lot to avoid this happening.

Has anyone else noticed something like this or should I take it back for service?

Thanks

Nobody has an idea or even suggestion? I swear forums get more worthless every year. 45 ppl read this in the past 2 days and nothing? Atleast Toyota forums had responses. Ban me or whatever for my response to a post which got none from any of you "Nissan enthusiasts" as you call yourselves. Bye bye altima forums Ill take my knowledge of 12+ years of tearing cars apart elsewhere where I might atleast get one suggestion.

My recently purchased 2010 Altima 3.5SR also experiences the same 'clunk' sound upon first driving out. It happens only once per drive/trip. (It appears to occur only after a cold start, but not certain as I have not done enough testing) My car had 35 mi when I purchased it and it now has ~250 mi.
I would agree with firewurx this does NOT seem normal. Common apparently; but not normal.
Everything else seems to be ok with the car, so I've been reluctant to go to the dealer as I have little, to no confidence in their ability to diagnose unusual issues. So I'm going to wait it out a bit.

From what I have been reading its normal for CVT.Some reviews i have read state the CVT sounds and performs very different from normal transmission and takes some getting used to.So what color 3.5SR did you get ? Post some pics.I wanna see all the 2010's i can .I have a brand new white 3.5SR Sedan waiting on me at home.I haven't even drover her yet
Had the wife go get it for me.I'm on a military deployment till november.Mine is sitting in the garage with 104 miles on the dash mostly from the drive home from where she bought the car from,

Thank Berg, Yeh, I'm actually not going to worry about the clunking too much for now. I'm just going to keep an eye out if anyone reports any adverse effects.

Congrats on your 3.5SR. Mine is in black, but I would have preferred to get White! I'll try to post some pics soon. Just haven't had much time. It's a great car overall, just wish it handled more like a sports car :-( (there's just way too much body sway). Apparently its a sports tuned suspension; so it may just be the OEM tires.
Eh, who am I kidding? - Is a Front engine, FWD sedan, with horrible weight dist... I shouldn't expect too much. Everything else is great though!

I too have a brand new 2010 3.5SR I just purchased it last week with 52 miles on it. I LOVE the car but just noticed the "clunk" sound on Monday morning (probably because every other time I had the music up too loud .
I called the dealer and they said that the sound is coming from the power steering fluid starting to pump back into the system after settling.
I only have the problem when I first start the car and reach 10mph there are no other incidences during session of driving. I was told it's not a problem but I don't like the fact that my car is so new and already has this "issue" They gave one recommendation: let the car warm up for a little bit before you drive (I didn't purchase this car because I like to be slow to get going). I'm going to try my own little test of driving straight for a long distance after starting it and passing 10 mph...no sound then I'm inclined to believe him; however, if there is a clunk I'm taking the car in. I'll let you know how it goes.

That sounds like a good idea!

Awesome. Look forward to your update - i highly doubt its the PS pump. I usually let my car warm up before I drive, and this clunk occurs more often than not.

I have a 2010 3.5SR too (bought in March), and it has makes this noise every time I put the car in drive and go about 10 feet. It's hard to ignore, but I hesitate to go to the dealership and get the run around.

I think all of you will find that it is your ABS pump making this noise. I haven't tested a 2010 Alty yet, but if they are anything like the 02-08's you will hear a distinctive humm/whirr/buzz from under the front floorboard.
Symptoms:
Only happens *once* per startup.
Occurs at less than 7mph.
Sound/clunk is brief (less than 3 seconds).

This is part of your ABS (anti lock brakes) Power On Self Test. The last thing the computer does is test the pump when you start moving. So you'll usually hear this backing out of your garage, o r upon initial takeoff. The car has to be in motion, but below about 5-7mph. This is completely normal. If you are on the brake when the test occurs, you'll feel it in the pedal.

On a side note, are the 2010's really 5th Gen Alty's? I always thought they were more like 4.5Gens? I mean, all of the hardware is the same as 2007-2008, only the wheels/fascias have changed right? Or am I missing something?

New guy here... first post. I've had my 2010 2.5 SL for just a week now, and I have that same clunk/click sound. Happens within the first 100 feet of driving, and then never occurs again that day - even after the car sits all day at work. Next morning - there it is again. Perhaps it's something turning on? Not sure.

When it first happened I thought I had run something over. After reading the above posts, I guess this is normal.
