My car's engine always feels like it's dragging in the front and sounds really really bad like it's about to explode or something it makes a lot of noise and ticking sound as well when I'm driving

The door blend actuators go out constantly. The car has three of them. When they go bad, there is a loud clicking or knocking sound behind the dashboard and the air conditioner and heater stop working. If it's cold, it blows cold air and if it's hot it blows hot air. I have replaced at least 20 actuators. Once they go bad, a new one last only a few months, which means there is a deeper issue. The dealer says chevy is aware of the problem and it is a well known issue; however, they have not issued a recall, dealer could not quote a price because they won't know what is wrong until they get in there. Dealer suspects chevy won't issue recall because the whole system is faulty and will cost thousands per car to fix.

Engine makes a knocking noise while accelerating. I drove another one and the noise was even worse, that one had 15000 miles on it. This seems to be a common problem with them all. I am very unhappy with this car. I don't enjoy hearing all this noise from a new car. (now has 6000 miles on it) if I can't resolve this problem it will be the last gm car I ever buy. The dealer had me drive another new 2012 impala when I mentioned the noise, it also sounded the same. Gm definitely didn't address this problem before production.

Engine makes a ticking noise or knocking noise while accelerating , I'm very concerned with this being that this noise started the next day after I had the car home from the dealership . I'm hoping this isn't a safety concern but it sure is a customer dissatisfaction. The dealer has tried to isolate the noise and could not and said I would have to wait for the manufacturer gm to figure out what is wrong. I'm very depressed about this having spent good money on a new car just to have it make more noise that a 40 year old car , and then being told I have to wait till someone complains enough to see if it can be fixed. I been told that this is a new engine in the impala and now am wondering if this engine is going to become a problem for thousands of people like myself. I have read some major concerns from people about the 06 impala and hope this isn't where my car is headed. Any help that I could get would be very appreciated, thank you.
