Engine Belts And Pulleys problems of the 2007 Porsche 911 Turbo

Purchased vehicle from Porsche dealer on Jan 2 2017 and operated it 1600 miles before it blew a coolant fitting and expelled coolant all over the road , rear tire, and rear of car. I was on a busy interstate on ramp and heard the belts squeal and saw steam in the rear view mirror. I could have very easily lost traction if there were no cars ahead of me going slow. Luckily was able to pull over immediately and turn the car off before causing engine damage. No one behind me lost traction in the slick coolant fortunately . Extremely dangerous condition that could easily cause a serious accident. Had vehicle towed to selling dealer 3 days out of warranty and received an estimate of $5200 to repair a coolant hose. Offered a 15% discount, then an additional $1000 off. I researched the common coolant fitting issue where the epoxied fitting comes loose or one of the plastic fittings break. The service manager acted like he had never heard of that and said they would replace the one hose . Declined repair and had vehicle towed to independent shop where it was discovered that it was a fitting , not a hose as the service advisor had stated. One other fitting was about to fail as well. This large well known shop performs upgrades to these fittings by welding them so they won't let go. $5000 to fix all seven fittings. Weld 5 aluminum fittings and replace the 2 plastic ones with aluminum and weld them also. Definitely a design flaw that could put a driver and others in a bad situation. Been without the car for over 3 weeks so far .
