My Vibe makes a sound when I start it sometimes. I've noticed it usually only happens when I cold start. If I start it again after it made the sound, it won't make the sound again. I'm starting to suspect it may be a camshaft gear problem? To be honest, idk jack (removed) about cars but I guess I'm trying to prepare for a $1000 fix lol. this video sounds a lot like it https://www.youtube.com/watch?v=lSafiPtq_OI though with mine it's much less loud.
Anybody have any similar problems? If so what did it end up being? I know I'm going to have to take it to a mechanic at some point. But I figured it wouldn't hurt to ask the forum
