Hi kitchm,I wanted to throw my similar issue into the discussion as well. 2019 JLUR with just under 12,000 miles has been at the dealer basically since Tuesday 7/23/19 for CEL and even though they see the codes in the computer, they claim they need to "make it happen" and run diagnostics while the code is active. They've driven it several times without event. I even picked it up Wednesday evening because they said they couldn't diagnose anything further until they saw it "live". I drive less than 5 miles and it happened to me twice. Stopped and started the engine and the CEL and all warnings want away. I called them and they told me to bring it back. They've had it since Thursday morning with no updates.
