JANUARY 2020
SUBJECT:

SAFETY RECALL
Rear Axle Brake Modulator Valves on certain
International® HV™ Series trucks built 02 May 2019
thru 18 July 2019 with 6x4 vehicle configuration, 6
channel ABS, non-air suspension and certain
wheelbases.

DEFECT DESCRIPTION
The drive axle brake modulator valves may not meet the requirements for
FMVSS 121 S5.3.4 Brake release time. Each service brake system shall meet
the requirements of S5.3.4.1 (a) and (b). This condition has no impact on normal
brake operation. However, an increase in the time required to exhaust the brake
chambers, could in rare conditions cause brake drag, which could cause a brake
or tire fire, resulting in possible property damage.

MODELS INVOLVED
This recall involves certain International® HV™ Series trucks built 02 May 2019
thru 18 July 2019 and built with 6x4 vehicle configuration, 6-channel ABS, non-air
suspension and certain wheelbases.

ELIGIBILITY
This procedure applies ONLY to vehicles marked in the International® Service
Portal℠ with Safety Recall 19519. Also complete any other open campaigns

UNITED STATES AND POSSESSIONS
The National Traffic and Motor Vehicle Safety Act, as amended, provides that
each vehicle that is subject to a vehicle recall campaign must be adequately
repaired within a reasonable time after the owner has tendered it for repair. A
failure to adequately repair within 60 days after a tender of a vehicle is prima
facie evidence of failure to repair within a reasonable time. If the condition is not
adequately repaired within 60 days, the owner may be entitled to replacement
with an identical or reasonable equivalent vehicle at no charge, or to a refund of
the purchase price less a reasonable allowance for depreciation.
Dealers must correct all vehicles subject to this campaign at no charge to the
owner, regardless of mileage, age of vehicle, or ownership, from this time
forward.
Dealers should proceed immediately to make necessary correction to units in
inventory. All inventory vehicles subject to this recall campaign must be
corrected prior to sale, transfer or delivery. If vehicles have been sold or
transferred and you are in receipt of Customer Notification Letters and
Authorization for Recall Service cards for those vehicles, the transfer location or
customer must be notified immediately from your dealer location.
Dealers must make every effort to promptly schedule an appointment with each
owner to repair his or her vehicle as soon as possible. However, consistent with
the customer notification, dealers are expected to complete the repairs on the
mutually agreed upon service date.
