I have a 2007 Impala LT with the flex Fuel option and the same. Winter was endurable in Chicago with the "No heat at Idle" problem. occasionally the gauges and alarms would go crazy, but adding antifreeze would fix for months. Air conditioning this summer in traffic caused the problem gauges and alarms too often. Also the gurgling sound indicated a serious problem. I suggested to my mechanic a new thermostat to fix the problem thinking it would be in-expensive. It cost $179. It did not fix the gurgling. Next is the water pump. I took it to the dealer this evening. I paid $54 for a checkup. Dealer thinks the problem will be covered under warranty. I will find out tomorrow.

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.

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.

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.
