Safety Recall: 3.5L V6 Timing Belt

Supersedes 19-026, dated April 12, 2019, to revise the information highlighted in yellow

AFFECTED VEHICLES

Year	Model	Trim	VIN Range
2018-19	MDX	ALL	Check the iN VIN status for eligibility.
2019	RLX	ALL	Check the iN VIN status for eligibility.
2019	RLX Sport Hybrid	ALL	Check the iN VIN status for eligibility.
2019	TLX	ALL V6	Check the iN VIN status for eligibility.

REVISION SUMMARY

Under INSPECTION, Step 5 was changed.

BACKGROUND

During production, a supplier produced some timing belts that do not meet specification. These timing belts may shred or slip, causing the cam shafts to fall out of timing. Camshafts that are out of timing will set DTC P0341: CMP Sensor and CKP Sensor Incorrect Phase Detected and/or DTC P0369: CMP Sensor Circuit Intermittent Interruption and the engine will run rough. Additionally, shredded timing belts may cause the vehicle to stall and not be able to restart, which increases the risk of a crash.

CLIENT 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 client 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

Inspect the timing belt and, if necessary, replace the timing belt. If the lot codes are not visible or the timing belt is damaged, a cylinder leak down test may be required and, based on those results, further repairs may be required.

NOTE

Only a small percentage of vehicles are expected to have timing belts that are out of specification. Only order replacement parts after you have identified an out-of-spec timing belt.
