Engine Cooling System problems of the 2006 Chevrolet Impala

The heat has never worked correctly unless you are accelerating. The vehicle can be warmed up and heating, but if its put into idle or at a stop it begins to blow cool. I have been told there is an air pocket that has to be bled out because there is a bad design where the hoses are above the block and they get clogged up. I have had it bled and it worked but now have had the same problem come back.

I have a 2006 chevy Impala lt 3. 9 with 55,000 miles just had to put water pump 2by pass hose and bottom hose bill came to around $470. This car has been babied ever since new and with top notch service performed regularly. Besides this problem the tire air sensors are also a joke replaced two of them at around $70. 00 each. Still don't work properly. While I'm on roll I should mention the remote start, unlock, system is also a joke, took it to a dealer told them it would not work anything, they came back to me two hours later and said the module in drivers door was bad, two remotes ,module, calibration and $917. 00 and they would have me on my way. Ha ha. Told them to put it back together and I was paying my 80. 00 for the time spent and leaving. As I was going to my car the service rep. Said when they put it back together it began working, everything but tire pressure info. I have read other people have remote problems just wondered how common this problem is. Also I cannot believe my water pump went bad @55,000 miles.

2006 chevy Impala seems to have hot heat near the passenger front by were your feet rest ,and I have already fixed the transmission twice and for some reason it is again making this real loud noise when I take it off of park it is really hard to move it in to park mode and when it does it jerks really hard.

I have a 2006 Impala with multiple problems. The main problem is the heater occasionally will not produce heat unless you are revving engine. Problem is that the cooling system is designed defectively such that it is prone to air pockets. If air pocket develops, chevy has issued a service bulletin detailing a complicated procedure whereby the system has to be drained and antifreeze then put back in system. If a mechanic is not familiar with this service bulletin, he may tell you about problems with head gasket, incorrect antifreeze mixture, etc. This problem may reoccur everytime the closed system is opened if not then closed as per the service bulletin instructions.

The power steering went out 2 times, could not control car. The water pump went out.
