The air conditioner still faulty. Replaced hoses and freon. The struts still leaking fluid around tire area since purchased. I see many complaints online at different forums about this. My engine light comes on intermittently anf when I have it tested it just says O2 sensors. The light will stay on for 1-2 days and then go out and remain off for several months at a time. Everything in the car is plastic and keeps popping off. I have replaced so many door and seat pieces that this is crazy even down to replacing motor mounts. I love Chevrolet but this by far has been my most aggravating and costly purchase. . . . I used to go to my local chevy dealer for service but I noticed when I log in to my chevy/gm profile they don't load anything innthe system for chevy to see you are really maintaining your car. These dealers are ripping people off.
