Recall 19V423 covers 55 2018 Flowmark Vacuum Truck vehicles with Voyager monitors that can reverse the backup-camera image. Repair will be free.
Flowmark is recalling 55 2018 Vacuum Truck vehicles equipped with Voyager backup-camera monitors because the screen can reset to factory defaults and show a reversed camera image. That reversed view can lead the driver to steer the wrong direction around an object behind the truck, increasing crash risk; the Flowmark dealer repair will be free once available.

What's wrong?
The Voyager monitor in the 2018 Flowmark Vacuum Truck is the display for the back-up camera. It is supposed to show the camera image in the correct orientation when the truck is powered up, so the driver can use the screen as a backing aid. The monitor also stores user settings, including image mode and volume.
On affected trucks, the monitor can lose those stored settings during startup. The filing describes the problem as an interruption while the monitor is loading user settings, tied to voltage dropping during power-up. When that happens, the monitor returns to factory defaults instead of the saved setup. One of those defaults can put the camera image into mirror mode, reversing what the driver sees on the screen.
Owners can notice the screen off after startup, a louder volume setting than expected, or the camera image appearing inverted. If the picture is reversed, treat the backing camera display as unreliable until the recall repair is completed.

What's the safety risk?
An inverted rear display can make the view behind the vehicle misleading. When backing up, that reversed view can lead the driver to steer the wrong way around an object and increase the risk of a crash. Until the repair is available, use extra care and do not rely on the display alone. Repair will be free at any franchised Flowmark dealer once available.
What should I do?
- Check your VIN to confirm your 2018 Flowmark Vacuum Truck is included in this recall.
- Use the Flowmark owner notice if you received one, then follow its repair instructions for the free back-up-camera display software update.
- Call ASA Electronics at 1-800-384-4400 or Flowmark at 1-913-749-1209 with questions, and reference recall number 19V423.
- Confirm the camera image direction before backing up until the display software update is complete.
- Bring the recall notice or the recall number to the service appointment.
What happens at the repair
Because the remedy is still listed as under development, do not assume a final dealer appointment is open yet. Once the repair opens, a Flowmark technician will work with ASA Electronics to correct the Voyager display settings so the back-up camera image is shown in the proper direction. The final dealer repair will be free once available. If you've already paid out of pocket for this display repair, Flowmark's general reimbursement plan covers documented expenses. Contact Flowmark or ASA Electronics with your repair paperwork to start the claim.
