2015 mdx was making a whining noise, acura service reps said it's a transmission issue and requires a full replacement. 45k miles and already needs a new transmission?! If it was not covered by warranty he said it would be a $6k-$7k repair. What?! I have lost all faith in this vehicle and frankly the entire acura brand. This car has been quirky since I got it. Strange rattles, weird shifts, electronics acting up. Getting rid of it as soon as its fixed. It's too bad. I was excited to get it last year.
