I traded in my wife's 2001 Sedona for the 2020 Telluride. We never had any issues with the Sedona. A month and a half after purchasing the brand new Telluride, we took a trip to Boston from D.C.. The Smart Cruise was amazing. It kept us in our lane, slowed down and sped up as needed for traffic. I could literally fall asleep with my hands on the wheel and feel confident that the system would keep me safe... although that is a terrible idea and I wouldn't do it, I could. The leather seats are super soft and comfortable. The problem occurred on the way back. There was traffic which came to a stand-still in New York. It was 82 degrees outside, we had the A/C running at 2. We were sitting for about 5 minutes when my wife noticed that the A/C was not blowing cold air anymore. I looked down at the temperature gauge to see that it was almost on the H. So I put the windows down, shut off the A/C, turned on my hazard lights, and proceeded to the break-down lane. As I was pulling over, the instrument panel started yelling at me. It said "Engine Overheated, Stop Engine Immediately". I shut off the engine and opened the hood. All of the liquids were still where they should be. I waited about 5 minutes with the hood open. I then closed the hood, turned on the engine, and with my hazard lights on, drove about 35MPH in the breakdown lane. The temperature dropped back down to normal temperatures. Later, we stopped at a drive-through. After about 3 minutes, the vehicle almost overheated again, so I shut the engine off until we could move forward in the line. This shouldn't happen in a BRAND NEW VEHICLE!!! This isn't some 1980s hoopdee. We scheduled an appointment at the dealership. On the way to the dealership, my wife took the video of the Telluride overheating again. The dealership gave her a loaner car while they fixed the problem. The next evening, they told my wife that the cooling fan was disconnected... and was probably never connected during assembly, which is why the engine overheated while standing still, but not while we were moving. While this was an annoyance to us, it could have been worse. If it had been someone who didn't know what to do, they could have allowed the vehicle to continue to overheat, which could have melted hoses and wires, causing major damage to the vehicle, or even caught fire. I understand that these Tellurides are the new craze for Kia owners, and they are selling them faster than they can get them to the dealerships, but Kia needs to do a better job of quality checking their vehicles as they roll off the line so that this doesn't become a major problem.
