Recently, Mazda released a statement on how to perform a bumper repair on their CX3 vehicles. Because of the advanced driver assist systems in today’s modern vehicles, repairing a bumper is nowhere near as simple as what it used to be. We at Telesis Collision Center feel that it’s our job to let car owners like you know about specific repair procedures that a car’s manufacturer releases. That way, you have a better understanding of the importance of a shop following OEM repair procedures when repairing your car.

Car repair is extremely complex nowadays. It requires extensive training from the technicians to be up-to-date on how to work on today’s vehicles. Also, they need to always to be checking the car’s manufacturer to see what the latest repair procedures are for each vehicle. It’s incredibly complex and can cause severe, lasting damage to the vehicle if incorrectly repaired. Almost every state in the country doesn’t require technicians to have a license to work on your vehicle. So, how do you know they are correctly repairing your vehicle? It’s anyone’s guess, but it comes down to where you take your car to be repaired. 

ADAS Technologies in the Bumper 

Advanced Driver Assistance Systems, or ADAS for short, refers to the new technologies in your car designed for safety. Some of the ADAS systems that use sensors behind bumper covers include adaptive cruise control and blind-spot monitoring. These advanced technologies are now commonly seen in today’s vehicles. However, they require specific repair procedures released by your car’s manufacturer to maintain the advanced safety features your vehicle is built with. These are known as OEM repairs, which are the best for your vehicle. They are straight from the manufacturer instructing technicians on how to repair your specific vehicle. 

Mazda’s CX3 Bumper Cover Repair Procedures

Although we are specifically discussing bumper repair on the CX3, the diagram below demonstrates the ways Mazda instructs technicians to repair bumpers on the 2019 CX-5 in three possible scenarios: 

When it comes to repairing a 2019 CX3 bumper cover, there are several OEMs with various levels of warnings. The blind-spot monitoring couldn’t be calibrated if there are obstructions on the bumper. The entire rear bumper would have to be replaced if the area around this specific ADAS system is damaged.

Here’s what Mazda has to say in the 2019 CX-3 repair manual: 

“Radar aiming cannot be performed correctly if obstructions which interfere with radar emission are stuck on the blind spot monitoring (BSM) control modules or the rear bumper. Perform the following procedure before performing the radar aiming. 

—Verify that there is no water, mud, soiling, sticker adhesion, or repairs done using putty application on the surface of the rear bumper and that there is no mud, soiling, or scratches on the blind spot monitoring (BSM) control modules…If the rear bumper around the BSM control module is damaged, replace the rear bumper.” 

The Importance of Following OEM Repair Procedures 

As you can see in the diagram above, three common bumper repairs require specific OEM repair procedures. Despite the importance of these repairs, most technicians will repair a vehicle their way based on “experience.” However, each repair is unique and comes with its own set of repair procedures. Due to the critical role BSM plays in vehicular safety, this is why repair technicians might need to replace the bumper if there’s any damage. 

You want to take your Mazda to an auto repair shop that knows to check the OEM repair procedures before they begin any repair for any vehicle. These are the best technicians out there because they know the importance of following OEM repairs. Any auto repair technician that performs a repair solely based on “experience” can severely damage the ADAS systems your car is built with. Not to mention, the overall structural integrity of the vehicle can also be damaged in the repair process.
