New Home issues. Advice requested.

About 3 years ago my wife and I decided to build a new home and move closer to our kids and grandchildren. We had a custom builder build it we have now been in our new home for 25 months. It has been nothing but one issue after another. Roofer left roof jacks off vent pipes. Water leaked into hot water heater and fried the control panel. Had to replace water heater. Trim around the front column rotted and I replaced all of that. Paint is cracking all over the exterior and now having to repaint entire house. Painter came to prep house and find three spot where fascia is rotting already. Latest is mold in wall near master shower. Haven’t figured out the cause of that yet. I have spoken to builder and basically they aren’t taking any responsibility and blames subs but says subs aren’t going to help because it’s been over a year. Do I have any recourse? Are there any paths that I can take to get them to take responsibility for poor quality or am I SOL? To sum it up to date I have spent $5k on water heater, $1k on column trim, & $500 on mold analysis. Quote for for painting and fascia trim work is $11k. Not sure how much it is going to cost for mold remediation and walk-in shower demolition and rebuild.
