This notice applies to your vehicle identified on the enclosed card.
Dear INTERNATIONAL 8 Customer,
This notice applies to your vehicle identified on the enclosed card. This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
Navistar has decided that a defect which relates to motor vehicle safety exists in certain 2018 thru 2020 LT® series trucks and certain 2019 and 2020 RH® series trucks built 02/10/2018 thru 06/10/2019 with International® A26 engines.
REASON FOR THIS RECALL
The connecting rod bushing over time may develop cracks or lose chunks of material, which could lead to connecting rod failure.
RISK TO MOTOR VEHICLE SAFETY
Connecting rod failure in some cases can result in engine shutdown with minimal warning; a stalled vehicle in or near the roadway can increase the risk of a vehicle crash.
DEFECT REMEDY
The repair will involve the installation of an engine calibration to warn the driver prior to engine connecting rod failure. Authorized repair locations have software and instructions to repair your vehicle. The repair will be performed free of charge and take approximately 45 minutes to complete.
ACTIONS YOU SHOULD TAKE

Navistar, Inc.
- 09/13/19 Navistar receives an initial field report describing issue with a fleet having five A26 engine connecting rod failures over the course of two months and Navistar quality started an investigation into the potential issue
- 11/01/2019 Navistar expands the investigation to include a cross functional team to search for other reports of connecting rod failures and begin analysis into root cause of the issue.
- 01/15/20 Navistar first considered the connecting rod failure as a potential safety issue and opened a defect investigation. Compliance started an industry history search and located three prior recalls to look into that could be potentially related based on similar failure modes.
- 01/22/20 Navistar obtained warranty data on connecting rod failures. There were 81 potential connecting rod failures, but no indications or reports of engine stalling in the roadway.
- 01/29/20 Navistar started contacting customers and drivers to understand what is happening before, during, and after the rod failures occur.
- 02/07/20 Navistar started reviewing driver comments received to date. Received several responses with driver comments, two reported that the engine shut down quickly and had to get to the side of the road.
- 02/13/2020 Started A26 engine in engine test cell with known bad rod for purposes of evaluated possible detection of knocking prior to failure and to obtain data after the rod fails to understand failure mode and how long the engine will continue to run.
- 02/19/2020 Navistar meets with NHTSA identifying the issue and reviewing reported connecting rod failures to date and reviewing engine test plans, and a few driver comments when the rod failure occurs. Identified two periods of time where a tooling issue at the supplier could result in some rods being produced with out of spec. straightness on the wrist pin end bore.
- 02/28/2020 Navistar reviewed engine testing to date, rod failures to date at the NHTSA quarterly ODI meeting. Discussed need to get more driver comments to understand how the failures occurs and what is happening before, during, and after rod failures.
- 03/16/2020 As part of Navistars plan to obtain driver comments, Navistar receives first report of engine rod failure where the engine shut down quickly and the vehicle could not get completely off the roadway and was in the right turn lane.
- 03/18/2020 Navistar provides update on rod failures reported to date, confirmation test developments, and driver comments obtained to NHTSA team. Also shared first Weibull predictions based on data received to date. Discussed concerns of additional reports causing vehicles stalled on side of roadway.
- 03/27/2020 Because test cell dyno was up to 394 hours with no signs of knock or failure with known bad rod, Navistar decided to expand test to include additional engines with known bad rods.
- 04/3/2020 Navistar meets with Technical Leadership to review failures to date, driver comments received to date, and engine dyno testing to date. Initiated work stream to define suspect vehicle population based on suspect rod production.
- 04/08/2020 Started to run a known knocking engine received from the field in another engine test cell to speed up data analysis.
- 04/20/2020 As part of Navistars initiative to obtain driver comments, Navistar receives second report of an engine stall where the vehicle could not get off the roadway. This incident was first report of an oil spill on the road.
- 04/23/2020 Navistar receives third report of an engine stall as a result of a connecting rod failure where the vehicle could not get off the roadway. Oil cleanup was required for this incident as well.
- 04/30/2020 Navistar finalizes the suspect population and declares a safety recall.
- 05/01/2020 Navistar continues monitoring engine connecting rod failures.
- 05/19/2020 through 07/27/2020 Navistar found four engine connecting rod failures outside the suspect population.
- 6/23/2020 Navistar initiates a review of the failure data.
- 08/05/2020 Navistar completes the investigation and determines the expanded suspect engine population.

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.
