Anonymous, CA (2014 Jeep Grand Cherokee Summit 3.0-L V6 diesel)"I had a knock sensor go out. It was running a little strange, not as responsive and the engine light came on. Took it to the dealership and they replaced it. All is good now."

Anonymous, CT (2014 Jeep Grand Cherokee Limited 3.0-L V6 diesel)"This jeep received a recall for a faulty fuel pump relay three years ago. Fuel relay would fail and not fuel going to engine. After replacing relay it worked well for almost one year, then replacement began failing. Returned to dealer who said they could find no problem. Problem recurred usually when starting, but also sometimes while driving. Did research on youtube, found a replacement relay and bought two. After replacing the jeep is fine but keeping the spare in the glove compartment."
Anonymous A., VA (2014 Jeep Grand Cherokee Overland 6.4-L V8)"My OBD reader gave a check engine light, indicating fuel vapor leak. The fuel filler neck was replaced to resolve the issue."
Anonymous, DE (2014 Jeep Grand Cherokee Limited 3.6-L V6)"Engine error code P0456. Minor emissions problem. Investigated but not resolved. Reset but code has returned. It sometimes clears itself and then returns again."

"Im currently experiencing check engine code P4055: leak in the evaporative emission control system. It doesnt prevent me from driving or even make for a ruff ride. I cant, however, use my remote start (until I get it fixed). After watching various YT videos Im in the midst of seeing if I fixed it. I have to drive it for up to 75 miles to see if the message clears. Not there yet. I dont think its fixed tho, so Ill have to try another remedy or I just may take it to a shop and have the technician perform a SMOKE TEST. Following that, Ill know what to replace or I may have the shop do it."
