2013 Grand Cherokee leaking coolant on driveway. Go under and look, it appears to be coming from lower radiator hose at the water pump connection.
This water pump was a replacement of the original which the bearings failed. The dealer said the original water pump was a bad design and my replacement was a different part number (improved). The original was replaced at 15,000 miles. Take the car to dealer and they said the water pump was leaking, replacement water pump lasted 16,000 miles. Additionally the thermostat was sticking and needed to be replaced. There were no symptoms for a bad thermostat so I asked the service rep how they found the thermostat issue and he said they scanned it. The rep said the water pump is covered under the power train warranty but the thermostat is not. The cost to replace the thermostat is $154.00 and they also need to do a "coolant system service" at $89.00, total of $264.00 (with tax). Went to pick up the vehicle after the work was completed and asked the rep why I needed a "coolant system service" at 31,000 miles when the coolant advertises 150,000 miles (OAT). He said it may have been caused by the water pump putting particles into the system, I then asked if they flushed the system and he said no just drained and replaced the fluid. At that point I asked to talk to the MGR. I asked the MGR why an improved water pump lasted on 16,000 miles and why they did not flush the system and he said they just changed the fluid because the color may not have looked right. How can the 150,000 coolant be bad after 31,000 miles? He had no answer about the water pump failure at 16,000 miles. Once again a wonderful time at the stealership!
