It sounds like its coming from the engine but I could be wrong since the sound is very deep and difficult to pinpoint. I can feel the rumbling / vibrations inside the cabin itself. It only happens when accelerating.
Funny enough, after about 10 minutes of driving the rumbling noise goes away.
Has anyone experienced this before? Car is a 2014 civic lx automatic with close to 100k miles.
I’ve done most of the general maintenance items which include:
Battery replaced this year
Unsure if this is related as it occurred around the same time, but the right side of my headlights (low beam) will not fire on immediately. I will have to wait about 5 minutes and it mysteriously starts working again. This happens everytime I start my car. Might be related but could also just be a failing relay harness for the bulb.
