NHTSA Complaint #11589686 — 2023 JEEP GRAND CHEROKEE 4XE

While driving home yesterday, the High Engine Temp alarm came on. This was just north of Virginia City, NV. I pulled the vehicle over and immediately smelled hot coolant when I exited the vehicle. I lifted the hood, and there was no coolant in the reservoir. I left the hood open and latched with the safety catch while I returned to Virginia City to the local market. The trip was mostly down hill so little excess strain was put on the engine. I bought some coolant and tried to refill the system. While I was doing this with the engine running, my son looked underneath and saw coolant streaming to the ground underneath the vehicle. We called AAA for a tow to get the Jeep to the dealership where I bought it yesterday eveing. I called and spoke to the Service Tech explaining my Jeep was at the dealership and why. I subsequently received a phone call from the Tech. He explained the water pump had "exploded." He informed me they did not have the part but could get one tomorrow morning and have my Jeep ready for tomorrow afternoon. He also stated he nor the mechanic had ever seen anything like this. This is the second incident report I have made on this vehicle for parts failing that no one had ever seen fail before. The first was for a rear brake caliper taht broke at the mount. I bought this vehicle last September new. I am concerned this is only the beginning of significant issues this make and model will experience.
