Engine dies suddenly while driving.
2008 Jeep Grand Cherokee diesel 4x4. Power loss, hesitation, mostly happens at low speeds and gets progressively worse. The vehicle idles fine, then when you step on the accelerator to move out into traffic it sputters and doesn't proceed as expected. Very serious safety issue especially since the computer sees no codes so the dealer doesn't know where to start looking. It doesn't do it all the time and it's impossible to determine when it will do it.
