My 2017 Jeep Cherokee went nuts when I came out of the grocery store. Every light on the dash came on and odometer was blinking. I talked to a buddy of mine who is a mechanic and he said it was most likely due to a low battery/bad. I removed the battery and took it to the parts store to have it checked out. It came back good and they fully charged it. I reinstalled it and all the lights went out except the Airbag and the Odometer was flashing. I tried the Proxi realignment with the AlfaOBD but it would never run through it completely. I made an appointment at the dealer and they fixed it for free under warranty, that was last Monday when my wife made a deal on a 2020 Challenger G/T. My sneaky salesman (I bought 5 cars from the same salesman and about 10 cars from the same dealer).
