Well today I found I have my 2nd overflow tank failure. Both have broken at the top nipple that the hose clamps to, right where it enters the tank, just below the cap. What's with this? Is it because the tank is part of the pressurised system and it can't withstand the heat and pressure on top of having the leverage of the hose hanging onto it? Whatever it is it is a bad design. I have 157,000 miles on my 2013 and I've replaced the clutch at 140,000 miles. Replaced the A/C compressor at 145,000 miles, and now two overflow tanks. Calgon take me away...
