Vibration with AC On When I stop at light - 2020 Pilot
 

Hi all, I just bought a CPO 2020 Pilot at 16K miles. Even when I was test driving the car I noticed a vibration but the dealer told me its normal. A few weeks went by and it was bugging me so I took it to service and they said they had to replace a engine mount and they did.

But the vibration is still there. Is it normal? It only happens when the AC is on and when I am at the red light. Even at the red light it comes and goes. Feels like something is working hard. Does not vibrate when I am driving.

I am really starting to worry that I was sold a defective car. What kinds makes we less scared is that its still under warranty and there is additional warranty due to it being certified pre owned.

I'd see if other do the same. I don;t think you have anything to worry about.
