Purchased acura mdx in january of 2018 so it is now 3 months. I believe there is something significantly wrong with its automatic braking system.

We both we traveling at the speed limit of 40 miles per hour when all of a sudden my car's brakes went on, causing me to swerve into the guardrail. From there, I was thrown into oncoming traffic causing a collison.
