my 2020 Touring had this go off at the 5K mark? Might be time related but the dealer said that these newer SUVs require a "unqiue" one time replacement of oil because of the initial way it was staged post manufacturing & it's potential for sitting for months on the lot. They wanted $160 to refresh the special treatment - I'm no where close to explaining this correctly but I told them a firm no. I think this was around the same visit as when they resolved my "too-tight" Infotainment cabling issue that caused the crackling and power loss during use - anyway they techs accidently performed the special oil change out even though I declined it - got it done for free
I trust that it was a good intentioned engine treatment but to get hit with a $160 mandatory fluid change out seemed excessive.
Here is a bit of advice for all of us. As a former ASE certified mech years gone by, it was always a given to change your oil after a break in period of 2-3k miles. This allowed for metal shavings from just break in. deposited in the filter system to be removed, any lowered viscosity in the engine oil as parts settled in and to refresh the oil system with virgin oil. In todays climate we have so many sensors involved in the cooling of not only the engine oil but also the transmission temp, I wouldn't be surprised you have triggered a sensor which could be to a number of controlled areas and the car has determined "svc oil needed" sure the oil life is based on millage and use. Oher engine sensors are based on Oil pressure and oil temp. That notion, change oil at 3k was bumped by the consumers and moved back to 5k intervals. I would be going to the dealer and getting an oil change, I would be freaking out it could be a collapsed or plugged oil filter which can and will damage the engine if not changed. r
From what I've gathered it seems like the Hemi issues have more to do with the fact that the manufacturer recommends using 5w20 oil in an engine that many drive hard and often times push to the limit. The oil doesn't hold up and problems occur. I know many who have switched to something like a 5w30 or 0w40 and have logged a lot of miles without issue. But if you have your oil changed at a Chrysler-Jeep-Dodge-Ram dealership they will put 5w20 in that engine per manufacturer recommendation.
I think that recommendation is a good one to adhere to with the current widespread adoption of GDI engine usage throughout the current automotive industry. Many GDI engines, ones with turbos in particular, have a reputation for being hard on motor oil. Even if they are not hard on oil they have been engineered to allow for excessive amounts of blow by due to lowered piston ring clearances which helps to cut down on tailpipe emissions. That leads to more fuel dilution and carbon soot ending up in your crankcase, getting rid of that stuff is top priority when too much of it occurs and the only way of doing it is by changing your oil. No time is a bad time to do that.
