1/2 second grinding sound at start.....Starter, Solenoid , VTC actuator?
Recently my 06 tsx (85,000 miles, automatic) starting making a 1/2 second grinding noise when I start it. It's scheduled to go in for a B1 service next weekend- was going to have them try to diagnose but....I'm not sure they'll be able to definitively say which issue it is?
It's normally on the first start of the day. But it doesn't do it every time.
My first thought was starter or it's solenoid sticking
Then on further research I ran across the VTC actuator issue
I don't want to end up spending $1000+ replacing both if the shop goes for one fix and it ends up being the other.
What's the best way to tell which of these issues is most likely making the noise? I can try to get a video of it to post tomorrow if that will help.
Any help/feedback would be greatly appreciated! Thanks!
