[QUOTE="Fitz5440, post: 441859, member: 22301"] Hello All... I'm new to the Jeep community having been a truck guy for many years. Over the summer myself and my daughter both bought Jeeps. Mine is a 2011 JKU w/ a 6 speed, as seen in my profile pic ,which just turned 111k miles. It came as you see in the pic along with a hard top. I've been getting engine pinging lately. I checked the oil, which was down 2 qt's. I added the 2 qt's and still getting the pinging. The pinging comes at all different intervals, all gears and RPM ranges. Also with and without the hardtop. I put it on a code reader and no codes showed up. Should I change the knock sensor or is there somewhere else I should be focusing? My second question is about my daughters jeep. Hers is an 08 JK, 2 door, stripped down model with an automatic tranny. It was purchased from a small used car dealer and came with a 30 day/1K mile warranty. A week ago she was driving home in a steady rain. As she exited the highway, it stalled. Couldn't get it started again and it was towed to a jeep dealer.

I'm asking alot of engine questions because if the failure was caused by a pre-existing condition that could/should have been noticed by the selling dealer, I'm going to push to have them pay for the new motor.
