Took my new 2021 Mazda 3 Hatchback in for rear bumper repair in August following a minor collision when someone backed into my parked car. The rear bumper needed replacing and San Antonio Collision Center did an amazing job on the repair. By looking at the car on the outside, you wouldn't know the car had ever been damaged and that the bumper had been replaced. There was only one problem, the blind spot monitoring system was not working properly. Conrad suggested I take it to the dealership or I could take it to someone they worked with for calibration, but there were no guarantees it could be repaired by his guy. No brainer, I decided to take it to the dealership. Life got in the way and three months later, I was finally able to take it to the dealership. Turns out the blind spot monitoring sensors were placed upside down. The bumper had to be removed to properly reposition the sensors before they could be recalibrate. The added expense to me could have been avoided if the sensors would have been placed appropriately, or if I would have taken it to a repair center that was Mazda authorized and knew how they were doing. I was hesitant taking it to San Antonio Collision Center (since they are not a Mazda Authorized Collision Repair Center), but I took a chance since everyone, including Conrad, was so darn nice. The electronics in cars are extremely technical and complicated. Lesson learned! No matter how nice people are, take your vehicle to an Authorized vendor who specializes on repairing your make and model vehicle. If you don't, you might end up like me...with an added but avoidable expense just before the holidays!
