2018 Porsche Macan Powertrain & Transmission Problems

The Macan engine cooling system is defective and dangerous. It is made with a plastic cooling lines that are poorly placed (and concealed) where they are subject to high heat and pressure and therefore break suddenly. The danger is that it happens suddenly and you have to pull over right away even in dangerous road situations to avoid complete engine damage/failure. My husband and I drove the Macan to Mammoth Lakes for instance for the holidays and had to pull over in a dangerous side of a windy cliff, which posed great risk to our safety. Not to mention the difficulty and danger for a tow truck to access us. It was further pitch dark and snowing. We waited hours for the tow truck which thankfully came but we easily could have had to spend the night in a dangerous spot. Porsche should have let its customers know about this vulnerability so we could have changed these plastic lines even at our cost to avoid such a possible situation. They were sued for this same defect on the Cayenne. It's something I would have paid for and changed but they are not wanting to publicize this dangerous issue. They are putting customers' lives at risk. When we were (luckily) towed to Mammoth, Mammoth does not have the Porsche parts nor many mechanics so the mechanic (who was booked out for weeks) there did a temp fix and we risked our lives on the way back as well. We paid around $700 for the temporary repair and maybe another $1341 for the permanent change of the lines when we returned. This is a serious problem. We need to be able to trust otherwise reputable manufacturers like Porsche and our government entities. Happy to provide receipts. This vehicle needs to be recalled. At very least, the customers need to know about the issue because the plastic cooling tubes are concealed and not obvious. Further the lines cannot be replaced where the vehicle stalled and have to be towed to a mechanic.
