I appreciate you reaching out, but all they will say is " it is low on antifreeze" I will ask them " antifreeze just doesn't evaporate, where did it go?" and they will tell me that they pressure tested the system and it tested good with no leaks. When I think about the other cars I have had and currently own that have not needed a drop of antifreeze added, and this will be the second time I have to bring it in for the same thing, I just naturally think it is leaking. But Chevy says it isn't, so that is supposed to cancel out the evidence and we are supposed to just be happy chevy owners.
I think it is good that you gmCustsvc folks check these posts, but this is not the only place folks are complaining about this issue. And if all data was compiled, it would probably be a pretty big collection of information about the same issue(s). BUT, again, If I brought all of that to the dealer, and set it on the service advisors desk, he would say " we tested the system and found no leaks, so we filled it up and you are good to go".
I have been through this before with this car on the sulfer smell. They say nothing is wrong, but everyone who I take around in my car sure smells it. Chevy said in the beginning it was the gas I use. They had me drive all over town filling up at different gas stations in case there was a " bad batch" of gas in my area. ha! I did everything they said for me to do and the smell is still there. So what happened the last time I brought it in for that? They said " no smell detected". If there is no smell detected, then they have nothing to fix and there is no issues with the car. I got custsrv involved and they told me the same thing " we talked with the dealership and they didn't smell anything". Of course they didn't! They cant have a record of it smelling like sulphur, so they just call me crazy and write on the report " no smell". So frustrating!
Do we dare to even talk about the uneven tire wear issue on the Impala and how the inside of the tires wear pre-maturely? Then when you bring it in to chevy they say everything is fine, but when you bring it into a local repair shop, they say it has too much camber, but there is no way for them to adjust the camber because Chevy didnt design it with any more room for adjustment! Nice!
Sorry for the rant!

I have a 2010 Impala. First problem was the sloshing...they bled the cooling system, fixed the problem for a couple days then it came back. They bled it again and it came back again. My question is - where is the air coming in? My coolant hasn't been low.
Also asked about the sulfer smell with my car - they couldn't reproduce the smell and said there were no code errors when they checked it.
Then I had no A/C and had a light on on the dash (can't remember what it was) and the display where the mileage is kept flashing something at me. I took it to the dealer and they said it was the 4th Impala that day with that problem. They replaced the thermostat and it worked.
Most recently, the sloshing came back and my heat wasn't working when I was stopped or using the remote start. They replaced the thermostat, suggested I flush the coolant system and I told them they could flush it at their cost if they felt it would help this problem but a coolant flush isn't even suggested with the mileage I have on the car....they didn't flush it but blew out the lines to the heater core.
Their shuttle came and picked me up - I started the car in the parking lot with the remote start then sat in it for a little bit while I figured out my plans for the day and tried to get organized....the car still wasn't blowing warm air (it was about as warm as if you breathe on your hand). I went right back in and told them, they said "you have to drive the car to get the thermostat to open up to get heat" Seriously! I live in a family full of mechanics and had to learn how to work on a car before I was even allowed to get my license!
We went and started 3 other Impalas on the lot and they all heated up fine - - without driving them.
Over a week later I am still having the same problem and now when sitting in traffic all I smell is anti-freeze. They asked if I was sure it was my car that smelled. Seriously, again!!
So, the dealer keeps my car all day and calls to say there is nothing wrong with it, it's heating up to spec. and they didn't smell antifreeze. Funny, the mileage was the same when I picked it up as when I dropped it off. So they didn't even bother to DRIVE it to check out the smell!
Your uneven tire wear is from the spindle being bad. Husband dealt with this on his 2007 Impala. They insisted it was just the police cars that had a spindle problem. Funny, they finally changed his and his tires were fine.
As he was fighting it, they suggested he get his tires rotated more often. He was already getting them rotated every 3,000 miles with his oil change.
Check the recalls or TSB on your car, I think they added the spindle on there.
My car is at another dealer today - we'll see what they have to say.

Well, this dealership was SOOO much more helpful.
They started the car with remote started, no heat, did it again, no heat. Started it with the key - had heat.
Checked the programming to be sure it was right since there was an issue with this model blowing air when it should have been blowing heat and vice versa - with the remote start. Programming is good.
The very nice mechanic THEN explained to me that when the car thinks it's about 48 degrees out the remote starter doesn't blow out really hot air...just warm air. Well, this makes complete sense with some of the issues I have had - obviously if the remote start automatically turns on the air when it's hot and heat when it's cold there must be a cut off point as to when it switches. Hhhhmmm - magic - just an explanation on how the car thinks and I felt much better.
They didn't stop there. They pressure tested the car, they started it, drove it, heated it up, cooled it off and checked the temperature and pressure tested it several times to be sure that there was no leak in any part of they system at any engine temperature. There are no leaks. That didn't mean that the mechanic had absolutely no concern though, he couldn't reproduce the "overheating" anti-freeze smell....but also didn't have an opportunity to really drive it in heavy traffic.
It was in teh 20's this morning when the mechanic started the car with the remote starter and it did heat up and defrost the windows. He ran it about 5 minutes took the temp, drove it then took the temp and even he said it was somehow hotter today.
Will watch to be sure that the sloshing sound does not return. It was nice to have heat today!
I don't know....is it possible that when they pressure tested it (the other dealership didn't) that maybe it got a bubble out or seated the new thermostat or some kind of gasket in there better?
They were quite worried yesterday that it may be a head gasket and took the extra time to keep checking on it and testing it. I'm satisfied with "today it has heat." and the explanation of the remote start process.

Glad you are getting some heat! I had my car back in the shop yesterday. Not for the heat or alternator or smell, but for a check engine light that Onstar said was a fuel delivery issue. I bring it in, and they checked it out and called and asked me if I was running E-85 in it, because the fuel trim was WAY off! I told them " no, I have not run that since I brought it in for the sulphur smell, because you told me not to run that". They looked into it more, and decided that it must have been a glitch in the ECM, and reprogrammed my computer and charged me my 100 dollar deductible. I asked them earlier in the day to look at my car again for the sloshing noise, since it seems to have come back. He told me that they looked at that issue and my antifreeze was just a little low, so they topped me off and I should be good to go. I went in last night and picked up the car and what do I hear on start up? the sloshing in the dash! Yup, guess they got me all fixed up. not! So, I guess I will have bring it back in again at some other time if the sloshing gets worse or I lose heat at idle again like last time. Weeeee!

Been reading these posts for the last half hour. Of course my 06 Impala has the same problem of no heat at idle. I burped the system yesterday and it took a half a gallon of coolant. While I was waiting for the air to dissipate I was looking through my owners manual. Noticed 2 pictures of the cap in there and each one said 18 psi. My cap is a 15 psi. Maybe they had 10,000 leftovers from a different engine they thought they'd get rid of and put them on our engines. Just a thought. Going to the parts store tomorrow for an 18 psi cap. How bout you?

Good morning hammurrzz,
It looks as though you're already in contact with us. Do you have a Service Request number (71-**********)?

Is it freezing up when she is using the remote start or when she is driving?
Apparently there was a TSB about the remote start on these cars - since they automatically turn on the heat when it's cold and a/c when it's hot - I guess that some of the programming for this was backwards. That is one of the first things they checked when I took my car to the good dealership.
