rough start, the glow plug symbol appears for about a second and the the diesel pre heat message doesn't appear at all. two strange things happen in 20-28 degree mornings after a warm up. About a mile down the road the engine cut out for a split second and then the diesel pre heat message came...
I have a 2018 Jeep grand cherokee. It can be in the mid 20'sF the diesel preheat (glow plugs) will not activate since I deleted it. Anyone have this issue ?
