Recall 17V402 covers 1,550 2015-2017 Freightliner 114SD, Business Class M2, and 108SD trucks for a missing brake check valve. Free dealer repair.

Freightliner is recalling 1,550 2015-2017 114SD, Business Class M2, and 108SD trucks because a required check valve was left out of the spring brake modulation valve. Without that valve, rapid air-pressure loss can spread between brake air systems, apply the parking brakes suddenly, and increase crash risk; Freightliner dealers will install the valve free of charge.

What's wrong?

The recall involves the air brake system on 2015-2017 Freightliner 114SD, Business Class M2, and 108SD trucks. A spring brake modulation valve helps manage air pressure for the spring brakes, and a check valve inside that plumbing is supposed to keep air from flowing the wrong way between the primary and secondary air systems. That separation is part of how the brake system preserves control of air pressure.

On affected trucks, the required check valve was not installed in one of the spring brake modulation valve ports. Without that valve, the primary air system is not isolated from the secondary air system. The problem is not normal wear; it traces to certain trucks built with spring brake modulation valves missing that required internal part.

The warning sign listed for this recall is inadequate warning to the driver or to following vehicles. Do not rely on a clear dashboard warning or an obvious outside signal before the brake air system is affected.

Who's affected?

Spans the 108SD, 114SD, and Business Class M2 across the 2015-2017 model years, all tied to the same air-brake component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

Rapid air pressure loss in the secondary brake system can spread to the primary system and trigger sudden parking brake application, increasing crash risk. There is inadequate warning to the driver or following traffic, so treat air pressure changes or unusual brake behavior as a reason to pull over safely and call a Freightliner dealer. Repair is free at any franchised Freightliner dealer.

What should I do?

  1. Check your VIN to confirm your 2015-2017 Freightliner 114SD, Business Class M2, or 108SD is included in this recall.
  2. Contact a franchised Freightliner dealer to schedule the free air-brake inspection and check-valve installation that keeps the primary and secondary air systems isolated.
  3. Bring the recall notice if you have it. If not, reference recall number 17V402 when you call.
  4. Call Freightliner customer service at 1-800-745-8000 with questions before the appointment.
  5. Avoid nonessential driving until the repair is complete.

What happens at the repair

At the dealer, a Freightliner technician inspects the spring brake modulation valve area and checks whether the required check valve is installed in the affected port. If the valve is missing, the technician installs the check valve so the primary and secondary air systems are isolated as designed. Parts and labor are free under the recall. Ask the service desk to reference Freightliner recall FL-740 when scheduling the inspection.

Frequently asked questions

What is recall 17V402?

Recall 17V402 covers 1,550 2015-2017 Freightliner 114SD, Business Class M2, and 108SD vehicles with a missing check valve in the spring brake modulation valve. Freightliner dealers will inspect the brake air system and install the check valve as needed for free.

What should I do if my 2015-2017 Freightliner 114SD, Business Class M2, or 108SD is on this recall?

Check your VIN to confirm your specific truck is included in recall 17V402. If it is, contact a franchised Freightliner dealer to schedule the brake air system inspection. Reference recall number 17V402 or Freightliner recall FL-740 when you call.

Is the recall repair free?

Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the remedy for this recall says Freightliner dealers will inspect the vehicle and install the missing check valve as needed free of charge.

What is the safety risk?

The risk is a rapid loss of air pressure in the secondary brake system, followed by a similar loss in the primary system. That pressure loss can cause the parking brakes to apply suddenly, increasing the risk of a crash.

What if I bought this Freightliner truck used?

The free recall repair still applies. Recall eligibility follows the VIN, not the original owner. Check your VIN to confirm whether your truck is included, then call a franchised Freightliner dealer and reference recall 17V402 or FL-740.
