Engine makes a "ticking" sound

I just wanted to make sure this is "normal" for this engine and others are experiencing it.
A lot more noticable when the engine is cold but still there when it's warmed up. The engine makes a "ticking" sound, especially at idle. It almost sounds like the old Isuzu Rodeo engines (also Honda Passport) that had problems with the lifters sticking.
Does anyone else's make this noise? The car has 8000 miles now and we've had it since May.

it happens with the QR25DE engine. when the engine turns off, you get that sound. I don't think I've noticed it as much with my hybrid, but with my 2002 sentra, it always did that after I shut the car off.

I guess I should clarify. This is when the gas engine is running/idling and not when it's shut off. The only noises I get with the car shut off normally are those wierd electronic noises the Altima Hybrids make.

so i assume that it is when your engine is still warming up. currently, there is a sputtering/rattling issue for the Altima QR's that, I think, has something to do with the engine mounts. currently, it's being researched by Nissan on how to get rid of it...but it's probably worth your while to tell your dealership that you have an issue.
i've read about this from my other forums

We do hear that noise in our car as well. It's reasonably quiet, but noticeable, especially in the very quiet hybrid car environment. I don't have any specific evidence, but it sounds to an old gear head like me like a ticking lifter. Ticking lifters have a lot of causes, but the most common one is lack of oil pressure (which is not the same as NO oil pressure). My guess is that the ticking is because of the extremely thin oil used in these NAH's which will result in a lower oil pressure until some revs are on the engine and the oil pump can generate some good pressure. At idle, this generally is not hurtful to an engine. If you hear it at speed, you have a problem you need to have investigated by a good mechanic.

Newby with a question

I'm thinking of purchasing the Altima Hybrid and I'm hoping you guys can help me with some information. When driving the Altima Hybrid and you are at a stop does the engine shut off (like an auto-stop type feature)? Does the car run solely on battery power up to a certain speed (like 25 mph) and then does the engine kick in? If so, is the transition between the electric motor and the gas motor a smooth tranisition (which isn't noticeable) or is it a noticeable one?

assuming that the car has warmed up and has adequate battery life left....
the engine does shut off at stop lights (probably before your complete stop)
the car can run solely on battery power up to 42 mph.
the transition is sorta noticeable, but I think you get used to it. Personally, it doesn't bother me unless your engine is still cold, that's a bit more abrupt.
I think some cars may be better than others on the transition. Make sure to test drive the exact car you are buying before committing to it.

Chris... on a cold start, the engine will usually run for a few minutes even at stop lights if the engine or the tempreature of the cabin is not warm enough. the computer looks at it this way in terms of order:
1. Get engine to operating temperature
2. Get driver to the temperature he desires
3. Then go into EV mode if there is enough battery power and below 42 miles per hour.
That may be overly simple but that is what I notice.
As far as the transition from gas to electric, when it happens and the car is moving it is rarely noticable. But when it happens at the stop sign or red light, you do notice the transition. As someone said, you get used to it easily and should not be the reason you would not buy it. They all do it.

I concur with Chris007 and others. In regard to the bump of the engine starting, I think it's mostly noticeable in cold weather, but really, at the end of the day, the car is so quiet and smooth, you probably wouldn't even notice the bump in a normal car. The transmission is a particular gem of engineering. Since it is a CVT, it doesn't have gears like a normal automatic, so you'll never get a downshift on hard acceleration, and you'll never get that annoying shifting back and forth when you're on certain types of hills. We just got back from a drive down to Santa Barbara (we live in the Bay Area). The car cruises all day at 80 (or more, depending upon your willingness to risk a road side chat with a cop), and gets 34 MPG at that speed. Hills are no problem; plenty of power. Around Santa Barbara, we rolled in stealth mode, up to about 42. To STAY in EV mode takes careful gas pedal management, but the car is forgiving and will drop back into EV as soon as you lighten up on the pressure...
