Recent 2010 EX 2wd Owner
I don't want to be the downer here, and I loved this car at first sight, but life with my 24K mile CT has been tough.
It appears I am in the unfortunate few category were nothing in the driveline works quite right. You will see other posts to this effect in this forum
Two service visits in the short time I have owned it resulted in a transmission software update and a "that's the way they drive" diagnosis, though the car continues to "shutter", sometimes quite dramatically, between 20 and 27 MPH, and has now developed a tendency to shake at any speed once warm.
I attempted a trade for a 2013 CT 4 cyl EX-L on Dec 31, but because that car came with defective i-MID software, decided to return it. I like the 4 cyl drive, and the idea of 5 to 6 MPG better gas mileage, the updated features like the backup camera and right side camera, and no more VCM (worse feature of the V6 models), but can't trust Honda quality anymore.
Good luck with your cars. I still have the 2010, and I suppose I will just keep trying to get it fixed. Happy New Year.
