I have had my brand new 2019 Wrangler Sahara from the first day I bought it, but when I filled it with regular fuel there was heavy knocking. I contacted the dealer shop that told me this is a fuel, then for last 3 months I use premium fuel from many stations. There has been continuous knocking and predetonation.
Update from Sep 28, 2021: I put 15,000km still engine predetonate continuously with premium fuel, dealer informed me this can not be fixed as it's manufacturing fault or behavior from the engine even being reported by other wrangler owners
