Did anyone go through problems with oil consumption, have their engine replaced under warranty, and now going through oil consumption issues again and a service 4WD problem? The code came up as C14A7 PTU Motor. I saw there are recalls for the PTU on older models. I have 79,700 miles and have had the Jeep for 4 years, bought it brand new. I got into near car crashes from the engine shutting down and now this? How is this safe to drive anymore? Anyone going through this and tell me your experience?
