Hopefully somebody here can help me.....I have a 2020 Grand Cherokee SRT (6.4L not the trackhawk). I started getting "service FCW, ACC and ESC" all at the same time. It started as a sporadic issue and hard to duplicate, but now it's becoming a daily issue. When these errors come on, it feels as if the rear differential disengages...I'm assuming it's because of the stability control issue. It's damn near impossible to back into my parking spot and I really have to be on the throttle to make a tight turn. I've cleaned the front sensor for the FCW/ACC so that's not the issue. I disconnected the battery and let it reset...still hasn't fixed the issue. All the grounds appear to be tight and intact, but I feel like it has to be a bad ground somewhere. I'm not able to get any codes when I scan it, so I guess my scanner is useless. If you guys have any tips before going to the dealer, let me know please.
