I have a 2010 honda fit sport. I had a recent break-in. They bashed the driver side window with a concrete slab/rock. I had the window replaced. however, the regulator is cracked. The mechanic bolted the pieces together, so its holding for now.

 

Im on the same boat few months ago and tried to ask the dealership about it but they hadn’t replied. But the best thing I recommend is to remove the ECU and open it. Try checking the cracks and replace the things that needed to be replaced. There are a lot of parts store online that offer replacement parts and you could seek them easily using the internet.
