CT200h Remote and Starting Problems

Interesting. I own a CT200h as well. Are you experiencing any radio signal degradation? I had similar symptoms a while back, and it turned out to be a faulty connection with the car antenna system. Did you check the plugs and cabling by any chance?

Radio signal issues? I hadn't really noticed, to be honest. But I haven't specifically checked the cable or plug connections. Where exactly should I be looking for the antenna connection?

Given your symptoms and the error memory, I'd wager it’s the same issue I had. The antenna connection is often near the bumper, as you suspected. But honestly, without the right tools and knowledge, you might do more harm than good. I would take it to a workshop to have it diagnosed before you cause additional damage. In my case the defective cable cost me around 95€.

Thank you so much for the insights! It sounds like a trip to the workshop is definitely in order. I really appreciate you sharing your experience; it's helped me understand what I'm potentially dealing with. I will let you know if this fixed the issue!
