In November 2023, our SUV started to over heat and engine shut off. We noticed the coolant reservoir was bone dry. We added coolant. It was bone dry again within a couple days. We had a mechanic friend diagnose and he told us it is the water pump. We took it to the Ford dealership and we were quoted $3000 to repair it. We could not afford this, so thankfully we met a mechanic that works at dealerships but also repairs on the side. He fixed it for $1000. Flash forward to November 2025 and we notice the heat in our car is not working. Couple weeks later, overheat warning and I'm forced to pull over with my 3 children in the car on a busy highway. Once car cooled down, we went straight home and forfeited our plans. Notice the reservoir is empty again. Refill it. It's empty within a few days. Come to find out, it's the water pump again and Ford dealership wants $4400 this time to fix it and our friend who fixed it last time wants $2000 to fix it. He had another Ford Explorer currently in his shop with the same problem. He said it will continue to fail. We are at a loss. Car overheats almost immediately and loses coolant almost immediately. Ford should have a recall on the water pump. Why does the engine have to be pulled out to replace the water pump that is just going to fail every 2 years. I have bought Ford since 2008 and swore I always would buy Ford. I have had 3 Ford vehicles. This experience with this vehicle and the Ford dealerships has changed my opinion. I will never buy Ford again. We are only at 125,000 miles and bought vehicle brand new in 2018-- so 7 years. . . Just 7 years!.
