NHTSA Complaint #11549563 — 2018 DODGE GRAND CARAVAN

My 2018 Dodge Grand Caravan will not turn the starter when I turn the key intermittently, especially when the temperature is hot. The key has to be turned on and off many times before the starter engages and the engine starts. The engine will turn off while driving the van on the highway which causes the power steering to go away. The van must then be shifted to neutral and cruise to a stop so it can be re-started after many tries as explained above. This is very dangerous because if you are on interstate in fast lane with cars behind you, it causes vehicle to slow down because engine stops without brake lights being engaged that could cause rear end collision and makes steering very difficult. This usually happens at least three times in succession before going away for this individual trip. There is no warning when the engine cuts off while driving. I have taken the vehicle to Dodge for inspection and they told me it was the TIPM, but would not replace it without charge. My research on the internet seems to imply it could also be an ignition control module problem.
