NHTSA Complaint #11436997 — 2019 JEEP COMPASS

On at least three separate occasions, without warning, the coolant sensor suddenly goes in to a false coolant temperature alarm as if the temperature has climbed to maximum heat. While the alarm is active, you are unable to accelerate and have no power steering. After a second, the alarm vanishes and coolant temperature gauge shows temperature back at normal operational level. This has happened while driving 65 MPH on a highway. This also happened while trying to make a left-hand turn at a busy intersection. This is quite frightening and if this were to occur at the wrong moment could easily result in an accident. Other owners of the same model vehicle have reported this exact same issue in online forums such as MyJeepCompass.com. In all reported cases, dealers and mechanics are unable to determine the problem after replacing the coolant sensor and trying every possible solution. I believe this is a software or firmware issue causing a false coolant temperature alarm to trigger. I reported this to Jeep and they only recommended bringing the vehicle to a local dealer.
