Recall 16V666 affects 3,329 2016-2017 Freightliner Business Class M2 and S2 vehicles for incorrect brake-warning display. Repair is free at any franchised Freightliner dealer.
Freightliner is recalling 3,329 2016-2017 Business Class M2 trucks and S2 chassis because certain instrument clusters show "PARK" instead of "BRAKE" during a brake malfunction. That wrong warning leaves the driver without a clear brake-malfunction alert and raises the crash risk; Freightliner dealers will complete the recall repair free of charge.

What's wrong?
The instrument cluster in the 2016-2017 Freightliner Business Class M2 and S2 is the dash display that shows warning lights, gauges, and required brake alerts. On these hydraulic-brake trucks and non-school buses, the cluster is supposed to help the driver recognize a brake system malfunction quickly and clearly.
The problem is in the brake warning wording, not in the hydraulic brake hardware itself. When a brake malfunction is detected, the ICU3s instrument cluster lights the Brake System Malfunction indicator with the word "PARK" instead of the required word "BRAKE". That incorrect label makes the warning less clear and puts the display out of compliance with the required brake and control-display standards.
Drivers still get warning signs when the brake system detects a malfunction. The filing says there are adequate alarms, including an audible alert, but the visual telltale uses the wrong word.

A matching year, make, and model does not confirm inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
If the instrument cluster shows "PARK" instead of "BRAKE," the driver can miss the required brake malfunction message even when other alarms sound. That confusion increases crash risk because a braking problem is not shown in the required words. Schedule the cluster replacement soon. Repair is free at any franchised Freightliner dealer.
What should I do?
- Check your VIN to confirm your 2016-2017 Freightliner Business Class M2 or S2 is included in this recall.
- Contact a franchised Freightliner dealer to schedule the free ICU3s instrument-cluster replacement that fixes the PARK warning shown instead of BRAKE during a brake malfunction.
- Reference recall number 16V666 and Freightliner recall FL-724 when you call.
- Bring the recall notice if Freightliner mailed one to you.
- Treat a PARK lamp during a brake problem as a brake warning until the cluster is replaced.
What happens at the repair
At the dealer, a Freightliner technician replaces the affected ICU3s instrument cluster with a new cluster. The repair addresses the brake warning display issue, where a brake malfunction indicator can show the word PARK instead of BRAKE. The recall repair is available now, and the replacement parts and labor are free of charge. Ask the service desk to confirm that the new cluster is installed under Freightliner recall FL 724.
