After hearing of some of the horror stories over many years of buying cars with some having electrical faults brakes overheating, engines seizing and many many other things, the CHR has been a pretty good new launch car tbh.
Seeing as it has been out just a few months it seems to have very few issues that are not easily rectified.
As other users have posted the biggest thing for most are unexpected things or items that just need getting used to.
My two issues were not the CHR's faults directly. 1st were scratches the dealer managed to put on the car. Super annoying.
The second was my mobile phones bluetooth stack wasn't compatible. Software update on my phone cured that one.
Both now resolved
If you are that worried about things, wait another 6 months at which point most "common" issues will have been found and ironed out with new builds.
