2017 Maserati Levante Brakes Problems

While driving my 2017 maserati levante going less than 20mph I notice the road was bumpy and tried to slow down and the brakes didn't respond. It felt like I was losing control of the car I continue to pump the brakes and it made this loud sound and then car skid to a stop. Thank god no car or person was in front of me. I have experienced this twice the first time it wasn't this bad just seem like the brakes weren't responding when I press the pedal. I just purchased vehicle feb 15 2022 and its now march 25 2022 from a certified dealer that car pass all inspections. There were no warning lights on during this scary incident or after.

When driving and approaching a stop at under 20 miles per hour, the brakes will fail and reverberate making a recoiling sound if I hit a bump or small pothole in the road. At that time, I loose control of the car because all braking systems fail. The car will continue to roll out of my control. There are no warning lights and the emergency brake also fails at this time. It is through the grace of God that I do not run into a person, auto or property. Again, this is a, "Certified" vehicle which I paid an extra $2,500/year to assure the vehicle would be safe and all additional issues would have been resolved. I have scheduled an appointment and will have the car repaired. Please follow up. Please note this is the 2nd major life threatening incident with this vehicle in the past 6 months and during the first 1,000 miles on a car that I paid an additional $2500.00 to assure that it was certified and had gone through the necessary inspections so that these issues would have been resolved prior to the release of the car from the dealership for my new purchase.
