Took car in for recalls no issues with that but after left put car in reverse to leave from another location my back up camera had quit working was working fine before the service but does not work now
Asked them abo it said nothing they had done would affect the camera
Also found a stray wire in the fuse box like they had made a jumper to jump power to something wire tied around the wiring harness don't know what kind of recall would require a jumper wire and tro disable backup camera.
