I got my 2007 Impala back Friday at 5:30 PM. All was covered by Warranty - Yea! Invoice says:
Pressure test cooling system
Locate leak at coolant crossover pipe gasket
Replace coolant crossover pipe gaskets.
Coolant 8.8 quarts
After I drove in traffic, I felt the top radiator hose. I could feel gurgling. I will be checking the reservoir. My gas station mechanic still thinks there is loose plastic in the water pump.
I hope that I find this before the Warranty expires.
Chevrolet tells me it is covered by 100,000 Power Train.
We will see.

Thank you for keeping me up to date on the repairs. Are you scheduled to go back to the dealership to have it checked out? Thank you,

I work at a chevy garage, and we've been doing alot of cylinder head gaskets on these for this type of problem. but any coolant leak will cause it.
#3582 of 3636 heat issues as well

I have an '06 Impala with the SAME issue. I took it in last winter (around Feb) and they said it was an air bubble in the line and things were "ok" after they took care of this. However now that I need to start using my heat again now, it is doing it again. I called the dealership and they said it is probably another air bubble. How frequently is this going to happen? I cannot afford a $150+ bill every 6 months! I am not happy with my Impala. I think it is interesting too that the issue starts after the warranty runs out. Imagine the luck of that!
How many time do you have to have something fixed before it's considered a lemon?!

When you are defrosting with heat, the AC system will engage in order to remove the moisture from the air within the car. This is why you will hear the AC clutch kick in in order to defrost and pull moisture.

I am also experiencing the swishing noise when I am in my card but that doesn't bother me as much as the air. My heater stopped working at idle as well. I took 06 Impala to the gm dealer and he told me the head gasket was leaking, the water pump needed replaced which would run me about $2500!
I personally know 2 people with the same car/problem but unfortunately at the time theirs were both under warranty.
I loved my car up to this point and have talked it up so much but I am very disgusted at the moment(not to mention freezing in town because its 7F out).

I am actually working on this problem with my friends car right now. Im in school for automotive technician and am bringing his 08 impala to the college tomorrow. But what I have come up with so far after doing an oil change/inspection already on the vehicle is that the serpentine belt was loose. We have picked up new coolant, a serpentine belt, and a new tensioner. My thought is that it is because of the loose belt not being able to operate the condenser properly at idle RPM's. I had a thermometer in the vent and was getting about 70 celcius while it was -17celcius outside while driving down the highway. But when at idle, it got frigid cold, pretty much to outside ambient temp.
I will let you know how it goes, and plan on doing the rad/heater core flushing and then testing it before replacing the belt/tensioner.
But for all of you other guys out there, give your belt a pull, if it feels loose then that may be the problem.

Looks like there is design flaw on these cars.I own a 2006 impala lt with3.5 litre engine,and I have the same problem.Just had the water pump replaced and the mechanic topped up the coolant made sure there was no air in the system by pressure tested it,this was end of summer,and now winter is here ....no heat at idle.Topped up again the coolant(both places,reservoir and radiator)still no heat at idle.And in Montreal it's dawn cold in witer time.
#3587 of 3636 2008, heat goes out when stopped
Dec 23, 2011 (1:00 pm)
I;m having a problem with heat too. Have 2008 impala with less then 70,000 miles. Heat is going out when stopped. Cannot pre-warm with remote start because of this. Coolant was gone in resevoir. Added some, was good under radiator cap. Ran it and I have heat now. Went out to check 2 hrs later and resevoir was down again but not as bad. Ran car again and still have heat. Called my mechanic and he said that it had to go somewhere, can't mysteriously disappear. Wants to check intake gasket soon. No warranty of course, I love my car til now. Had similar problem with last car, 2001 lumina, was gasket and it cost me $500 thru a friend. What is GM going to do about this. How do we get them to do a recall and fix this problem? Seems enough people have the same problem.

I'm in the same boat. I figured they would have gotten this fixed by now. I owned a 2005 Impala and it did the same thing. They said it was air back then, and fixed it, but it came back after awhile. I traded the car. Now I have a 2010 Impala, and it is doing the same thing. I read about the coolant being low, so I just went out and checked mine and there are puddles of coolant in the bottom of the resivoir so it seems low. I plan on bringing it into the shop next week so I will see what they say. It is still under warranty so they will say it is only air in the system, then when it goes out of warranty, they will say it is a leaking head gasket and want tons of money! I think this will be the last Chevy I own. I still have the sulfer smell that GM says is the gas I am using, but it is the same gas I use with my 2012 Elantra and it doesnt smell bad. interesting. ALso my impala has a water sloshing sound in the dash when I turn a corner, like water is trapped and now no heat at idle. I just dont have these issues with the other cars I own or have owned ( Kia Sorento, 2011 elantra, 2009 honda civic)
After 30 years of promoting GM products, I just cant do it anymore. Sad.
