Our 2017 MDX Sport Hybrid has starting to make a strange grinding noise when making sharp left turn. It seems to be coming from the front-end, so I don't think it has anything to do with the Torque Vectoring. Any ideas what it could be? Thank goodness I purchased extended warranty back in September. Will ask SA to check on it next oil change.

 

Anything caught up in the brakes (pebble or foreign debris in against the rotor or backer plate)? Would be surprised but could it be a CV joint? CV joints tend to "complain" when making sharp turns. Just some thoughts to get you started............

 

I had a similar issue with my 2018 Hybrid. Took it into the dealership and they found nothing. Took it to my mechanic buddy and he found nothing. I rotated my tires and the noise stopped. Not sure if it was a rim issue or not but I didn't look into it once the noise stopped

 

How many miles on your vehicle?

 

Only about 32K miles

 

Well that is pretty low to get a ripped CV boot and dry joint. Let us know what your mechanic says. I would go to the dealer because there is a chance they would fix for free if it is out of warranty as your mileage is so low.

 

I would agree that 32K is low mileage for a CV joint to be showing signs or making sounds related to failure so early, but I suppose anything is possible.
