Had no issues with car until 1/28/22 @ 10:45 pm. Driving on interstate and all of a sudden "HEV Warning - Do not Drive", etc. Got off interstate in about 3 miles (limped). Shut off car, and it would not restart, show ready, nothing. Got towed to closest dealer (45 miles - what a problem). Dealer found SAFETY FUSE and RELAY INOP. Replaced Safety Fuse and Relay. Also performed Aux Canister Installation (21-01-036H), Engine Monitoring Logi (21-01-023H-4), Anchor Pretensioner Ins/Label (17-01-061). Picked up car and it ran fine for couple of days. Then noticed it seemed to slip/stall when it was coming out of EV mode a few times. Wasn't really bad and not real often, but it got worse/more common. Then on 9/2/22, HEV Warning again, just as I was pulling off interstate exit. Was able to get car to apartment (1/2 mile) but it didn't have much power. Car sat in garage for 10 days. I rented a tow dolly so I could take car to dealer. When I put car on dolly @ 6 PM, the check engine light was still on. After towing it 450 miles (to my local dealership), when I started it to take off tow dolly, check engine light was not on. Dealership ran diagnostics and stated there were no codes stored (seems like and issue to me). They supposedly test drove it and said everything was fine. Again, picked up car. 3 days later, was back on interstate (my job involves travel between 2 locations 450 miles apart every other weekend), and again had the slipping feeling when coming out of EV mode. Also noticed now that the READY light would flash off, then back on. Sometimes it flashed once, twice of even 3 times, again mainly when coming out of EV mode. Noticed that if I had cruise control set when this happened, it would turn cruise control completely off. I could turn it on, but not set it, and it never turned it off when ready light would flash. The ready light flashing seemed to be worst when trying to accelerate, and car seemed to slip or delay before switching to engine power. Then today (10/20/22), when getting off interstate to go to my apartment, the HEV warning comes on again. Basically it completely shut off on its own. Seemed like total loss of power/voltage. Put in park, set parking brake, got check brake message. After about 3 minutes, was able to get it back running, back to apartment, and check engine light is on. I lost most voltage (radar detector turned off) but radio stations are still in memory. When I got to apartment, I pulled the fuse in the trunk area and reseated it. Check engine light still on. Anyone have any ideas what may be causing these issues? I don't want to go back to dealer and they say there is nothing wrong again. Most of my travel time is done at night and don't want to get stranded on side of interstate between Nashville TN and Charleston SC.
Any advice would be appreciated.
