Safety Recall Y4K: 2018-2019 Honda Odyssey Battery Terminal Inspection and Transmission Replacement

April 12, 2019

Loose Battery Terminal Connections

A damaged parking rod can allow the vehicle to roll when parked, increasing the risk of a crash or injury.

 

NHTSA Campaign Number: 19V299

Manufacturer Honda (American Honda Motor Co.)

Components POWER TRAIN, ELECTRICAL SYSTEM

Potential Number of Units Affected 50,504

 

Summary

Honda (American Honda Motor Co.) is recalling certain 2018-2019 Odyssey vehicles. Loose battery terminal connections or a degraded battery may cause the Transmission Control Unit (TCU) to unexpectedly reboot. Upon rebooting, the TCU may shift the transmission to the “Park” position, possibly damaging the parking rod.

 

Remedy

Honda will notify owners, and dealers will ensure the battery terminal connections are secure and will update the TCU software, free of charge. Additionally, the parking rod effectiveness will be checked. The recall began May 31, 2019. Owners may contact Honda customer service at 1-888-234-2138. Honda’s numbers for this recall are Z4J, Y4K.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Safety Recall: 2018-19 Odyssey Battery Terminal Inspection and Transmission Replacement

 

AFFECTED VEHICLES

Year	Model	Trim	VIN Range
2018-19	Odyssey	Touring, Touring-Elite	Check the iN VIN status for eligibility.

 

BACKGROUND

A momentary voltage loss to the TCM, usually caused by a loose battery terminal, can cause the transmission to shift to Park while driving. When this happens, the parking mechanism could get damaged, and the vehicle may move while the shifter is in Park.

Honda has developed software to correct this issue. See S/B 19-046. This service bulletin provides information to replace the transmission of vehicles that were identified as having their transmission shift to Park while driving . The new transmissions come with the new software.

 

CUSTOMER NOTIFICATION

Owners of affected vehicles will be sent a notification of this campaign.

Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Some vehicles affected by this campaign may be in your new or used vehicle inventory.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it.

 

CORRECTIVE ACTION

• Replace the transmission (the new transmission comes with the new software).
• Inspect the battery terminals.
• Clean or replace the battery terminals and/or battery if the terminal inspection fails (an extremely small percentage of vehicles may require a new battery or battery terminals).

.

BATTERY TERMINAL INSPECTION

1. Inspect the positive and negative battery terminals.

NOTICE

• Battery terminal installation on this vehicle is critical. Failure to follow the terminal installation or inspection procedures could cause electrical problems, stalling, and/or DTCs to set. Do not over torque the terminals, and do not use an impact gun.
• Battery terminal installation must be level or below the post. See GOOD and NO GOOD example pictures.

Compare both of the battery terminals to the examples below.

Do the battery terminals look like the good example?

Yes – Go to step 2.

No – Go to TERMINAL REPAIR.

2. While holding down the terminal, torque both positive and negative clamps to 4-6 N•m (35-53 lb-in).

NOTE
