NHTSA recall 20V346000
Service Brakes, Hydraulic · Mazda Motor Corp.
Details
What's wrong: The front brake caliper mounting bolts may not have been tightened properly during assembly, possibly allowing the calipers to loosen.
Why it matters: Loose brake calipers can reduce braking performance or interfere with wheel rotation, affecting vehicle handling. Either of these scenarios can increase the risk of a crash.
The fix: Mazda will notify owners, and dealers will inspect the front brake caliper bolts, tightening them as necessary. If bolts are missing, the affected brake caliper will be replaced. Repairs will be performed free of charge. The recall began July 24, 2020.
