Uneven idle. No codes. Tapping on the passangers side engine inside the engine at idle. The tapping will slowly get louder over time at idle just sitting. The tapping increases with engine speed.. i have a 2019. Its been doing that sense it it 10k miles. Everytime i go to the dealer they say oh i drives fine. After the engine is warmed up to temp the tapping stops. I was told they will not give me a new engine or fix the issue because there is no code.. they need a code to do engine maintance..
