New here...created account just for this discussion...hope the necro is not too great... So my 2018 just hit 6,200 miles and the engine light came on. Oil "gauge" said I have 26% oil life remaining, code refers to a problem with the emissions system, so I take it in. Dealer said "no oil visible on dipstick". (!!!!!!!!!!!!) So they filled it and said all clear...hmmmm. EDIT: My truck was built on the last week of 2018 production, thought it would have all the "hot fix" TSBs on it by then.
