NHTSA Complaint #11701592 — 2021 JEEP WRANGLER

I was driving on the freeway, 65mph, in Los Angeles and the '21 Jeep Wrangler 4xe started showing a bunch of error messages telling me to safely pull over, loss of propulsion, etc. I lost power and was unable to drive past 38mph. Upon getting to the end of the off-ramp and before coming to a full stop, the vehicle threw itself into parking gear. I shifted to Park, and it wouldn’t shift out of Park, while I was blocking traffic on the off-ramp, which could have been a dangerous incident. I required a tow truck. There was a Check Engine Light and a 12V battery light while I was bricked. The tow truck was unable to jump start it. The dealer provided a pre-scan report showing stored codes P0607 (ECU Internal Performance) and P1B13 (Park-By-Wire Unintended Out of Park). Refusal to Repair: The dealer just replaced the 12V battery and "cleared the codes" (per their invoice). There is a known TSB 08-054-22 (NHTSA ID 10248015) specifically relating to code P0607 software logic, but they refused to look into it further. I didn’t have confidence in their diagnosis, and when requesting them to do a safety test drive with me, they refused. When I pressed for safety verification, the Service Director told me to “leave the dealership and never come back.” I was genuinely concerned about the safety of this vehicle and their lack of investigative diagnosis, specifically their refusal to verify if the TSB was performed to ensure the Hybrid Control modules have up-to-date software. They refused to offer any help and just told me to “take the vehicle and leave.” I don’t believe it’s normal for a car to lose propulsion from a weak 12V battery while driving. There seems to be a more complicated communication issue (P0607) that is happening, and it very much concerns me as losing propulsion on the highway is very dangerous.
