I have a 2008 Infiniti QX56. When I start it up it has a grinding noise that only lasts for maybe 30 seconds, 1 mechanic said it could be the timing chain and once the oil circulates it shuts off. It will have to be replaced eventually but isn't damaging right now. Then I was told it was related to BLSD. I have attached photos because nobody can tell me what this dash light means and no check engine light is on. My rear tires have a slight angle in but nothing major. So I'm just looking for someone that can send me in the right direction because clearly these local Mechanics don't know crap about Infiniti and the closest dealer is 3 hours away from me! Thank you!
