Hi, disappointed in the Cherokee throwing a check engine light today and totally running like garbage. Seems to be a misfire although I have not put a scanner on it. Where is the OBD2 on these things under drivers dash like the Grand Cherokee?

What happens is the check engine light blinks goes off for a bit then back on, drives sluggishly and the auto start/stop is disabled.

The car is still under CPO, bought it 3 months ago and put on 3500 miles. Any ideas?

Recommendations?

Thanks

So it is a misfire on cylinder 6. The thing that sucked is that I had to take it to a jeep dealer to figure that out as my mechanics scanner could not get past the gateway. I know in MA there is a law that states 3rd party mechanics have access to codes and such. How do I get by this?

really not too happy right now

Take it in and make them fix it. If you haven't exceeded 36,000 total miles, I would recommend some kind of Mopar Maxcare Warranty on any Jeep. I was lucky and was probably one of the last few to get the Lifetime MaxCare. I'm not touching or paying for anything, except the normal wear parts like brakes. I plan on keeping mine till the wheels fall off, and then I'll make them fix it, and then drive it till they fall off again...😉😎

thanks @Flybynightcru i will have to look into that. But my mechanics scanner should have been able to work. Anyway since all local dealerships are booked for the next month or so Jeep said they would reimburse if I went to a 3rd party mechanic. I am doing that route. Stinks because I am finally leaving to go skiing on Friday.

My car had 49k on it when I purchased, so the maxcare option might be out. The CPO stands for certified pre-owned and that is good until 100k or 8/28/2026

on 2019+ models, it was added to the CANBUS. To allow AlfaOBD to communicate with all modules, you need to get another piece that will allow communication. Go to the AlfaOBD site for more information for 2019+/Security Bypass Module.

So I did speak with Jeep Customer care and they said the would cover the repair even with a 3rd party. I have documentation stating that. Now when I send in reimbursement they state it is not a covered repair. I believe CPO which states. Would ignition coils be covered under CPO?

The CPO also has a 3 month/3,000 mile Maximum care warranty which starts on the date of the CPOV sale. I am under 3 months and 3000 miles

Hello, I had the same issue. Code said misfire cylinder 5. Dealer said was just a loose wire, all seems ok now. 👍
