NHTSA Complaint #11644361 — 2021 JEEP WRANGLER

Sudden loss of power. Vehicle completely lost response to accelerator pedal while driving: Had a very strange experience last night. I have been barely charging my 4xe after 95b recall trying to maybe slow down battery degradation and drive it like during the recall period. Last night I was going down a rural road. I rolled up to a 4 way stop slowing down from about 55mph to stop. Vehicle was in hybrid mode, and cluster was at <1%. I had barely stopped, I don’t think the ICE shut down. I tried to accelerate to clear the intersection and I had 0 power. Car would barely move and slowly rolled in the intersection. Engine was running but not responding to the accelerator with RPM increase, just like when you try to rev at idle. No response to half or full throttle. I just slowly rolled in the intersection (scary situation, luckily no heavy traffic) I turned my hazard lights on and tried again to accelerate, 0 response, no MIL light, still gas in car. I tried to change drive mode to electric, message “unavailable, battery depleted” (no surprise there), tried e-save no response to throttle either. Last resort I put tranny in park and re-cycled start/stop. HV battery had enough power to start engine and responded to throttle and I was back driving. Did another 10-15 miles yesterday, no wild issues (sometimes it feels a little jerky, but that could be just me now). I did some heavy accelerations. Power meter went to 100, re-charged on coasting and did that for 4 or 5 repetitions. No warning lights ever. Checked my SOH last night and it had dropped to 80.8%. I decided to charge on L1 outside. Didnt have full SOC this morning, just 75% on dash. Drove normal this moaning, stayed in electric mist of the time. My 75% was completely depleted after maybe 10 miles driving. All seems typical for a poor SOH HV battery, except the loss of power and 0 response to throttle. Very scary and potentially dangerous.
