In the affected 227,335 U.S. vehicles, the rearview camera image may not display properly, according to a July 14 recall report from NHTSA.
On certain vehicles, the rearview camera wiring harness may become damaged from vibrations during normal vehicle use or closing the liftgate due to improper design of the harness fastener. Connector pins may wear out, causing high electrical resistance. Due to these defects, the rearview camera may display a distorted or flickering image. Distorted or flickering camera images while reversing could affect driver judgment and increase the risk of a crash, the report said.
For all recalled vehicles, Mazda dealers will inspect and replace the rearview camera as necessary. In addition, dealers will install a wiring harness fastening seal. All repairs will be performed free of charge.
Mazda submitted nine field reports related to the defective cameras, which were supplied by Panasonic Automotive Systems Co. of Japan, NHTSA documents said.
"There have been no reports of any accidents or injuries due to the defect," Mazda said in a statement.
Mazda will notify all affected owners of the issue via letters expected to be mailed Sept. 12.
