On July 15, 2020 Toyota filed a Noncompliance Information Report (NCIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to conduct a voluntary Safety (Noncompliance) Recall on 2018-2020 model year Tundra vehicles.

 

Condition

In the subject vehicles, the wire harness connected to the front turn signal bulbs was assembled incorrectly, causing them not to illuminate as brightly as intended.  This can cause the subject vehicles not to comply with a certain Federal Motor Vehicle Safety Standard requirement. If oncoming traffic is unable to notice the front turn signals or front hazard warning lights, it may result in an increased risk of a crash.

 

Remedy

Toyota dealers will modify the wire harness connected to the front turn signal bulbs  FREE OF CHARGE.

 

Covered Vehicles

There are approximately 183,400 vehicles covered by this Safety (Noncompliance) Recall. Approximately 760 vehicles involved in this Safety (Noncompliance) Recall were distributed to Puerto Rico.

 

Owner Letter Mailing Date

Toyota will notify owners by mid-September 2020.

Toyota makes significant effort to obtain current customer name and address information from each state through industry resources when mailing owner letters. In the event your dealership receives a notice for a vehicle that was sold prior to the Safety (Noncompliance) Recall announcement, it is the dealership’s responsibility to forward the owner letter to the customer who purchased the vehicle.

Please note that only owners of the covered vehicles will be notified. If you are contacted by an owner who has not yet received a notification, please verify eligibility by confirming through TIS prior to performing repairs. Dealers should perform the repair as outlined in the Technical Instructions found on TIS.

 

Dealer Inventory Procedures

New Vehicles in Dealership Inventory 

There are approximately 2600 vehicles in new dealer inventory as of July 15, 2020

Under Title 49, Section 30112 of the United States Code, a dealer cannot sell, offer for sale, or introduce or deliver for introduction in interstate commerce a new motor vehicle when it is aware that the vehicle does not comply with an applicable Federal Motor Vehicle Safety Standard or contains a defect related to motor vehicle safety.  Further, 49 Code of Federal Regulations §577.13 requires us to provide the following advisory:  It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied. Toyota reimburses dealers for flooring costs associated with new vehicles held in dealership inventory until the recall remedy becomes available.  Toyota provides these flooring reimbursements at 60-day intervals.  Toyota reserves the right to withhold or charge-back any flooring reimbursement funds that may have been paid to the dealer if it determines that a new vehicle subject to a safety recall was sold without first being remedied.

Vehicle Safety Recall completion should always be verified through TIS. We request your assistance to ensure involved vehicles are identified and not delivered prior to performing the remedy.

 

 

NOTE:

• New vehicles in dealer inventory subject to a Safety Recall must be remedied before delivery into commerce under a sale or lease. Dealer-to-dealer trades as well as vehicle sales between dealers should not be made until a vehicle is remedied.
• Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle Inventory Summary available in Dealer Daily (Non SET and GST dealers: https://dealerdaily.toyota.com/). The Vehicle Inventory Summary may take up to 4 hours to populate information for newly launched campaigns.

 

Inspection Reminder Mirror Hang Tags for Covered Vehicles in New Dealer Stock

To easily recognize vehicles involved in this Safety (Noncompliance) Recall, each dealership should utilize Inspection Reminder Hang Tags. Inside the vehicle’s glove box are stickers containing the VIN. Apply one of these stickers to the hang tag and install the hang tag in the vehicle. A sample copy of the Inspection Reminder Hang Tag has been included for your reference.

Part Number	Description	Quantity
00411-140003	Inspection Mirror Hang Tag	25 Per Pack

 

NOTE: Dealerships can order hang tags from the Material Distribution Center (MDC).

Vehicle Safety Recall completion should always be verified through TIS. We request your assistance to ensure involved vehicles are identified and not delivered prior to performing the remedy.

NOTE: Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle Inventory Summary available in Dealer Daily (Non SET and GST dealers: https://dealerdaily.toyota.com/). The Vehicle Inventory Summary may take up to 4 hours to populate information for newly launched campaigns.

 

Pre-Owned Vehicles in Dealer Inventory

To ensure customer satisfaction, Toyota requests that dealers complete this Safety (Noncompliance) Recall on any used vehicles currently in dealer inventory that are covered by this Safety Recall prior to customer delivery. However, if the campaign cannot be completed (for example, due to remedy parts availability), delivery of a covered vehicle is acceptable if disclosed to the customer that the vehicle is involved in a Safety Recall.

Toyota expects dealers to use the attached Customer Contact and Vehicle Disclosure Form to obtain vehicle buyer information. Dealers are expected to provide a copy of the completed form, along with the most current FAQ, to the vehicle buyer. Toyota and the dealer may use this information to contact the customer when the remedy becomes available.

Keep the completed form on file at the dealership and send a copy to quality_compliance@toyota.com. In the subject line of the email state “Disclosure Form 20TA12” and include the VIN.

NOTE: Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle Inventory Summary available in Dealer Daily (Non SET and GST dealers: https://dealerdaily.toyota.com/). The Vehicle Inventory Summary may take up to 4 hours to populate information for newly launched campaigns.

 

Toyota Certified Used Vehicle (TCUV)

The TCUV policy prohibits the certification of any vehicle with an outstanding Safety Recall, Special Service Campaign, or Limited Service Campaign. Thus, no affected units are to be designated, sold, or delivered as a TCUV until all applicable Safety Recalls, Special Service Campaigns, and Limited Service Campaigns have been completed on that vehicle.

 

Toyota Rent-A-Car (TRAC) & Service Loaners

Toyota requests that dealers remove all TRAC and Service Loaner vehicles from service that are covered by a Safety Recall unless the defect has been remedied.

Make/Car Line	Model Year	Manufacturer	Production Period
Toyota / Tundra	2018-2020	TMMTX	February 22, 2017 through May 29, 2020

 

Applicability	Part Number	Part Name	Component Description
Toyota / Tundra	82111-0CD40 82111-0CD50 82111-0CD60 82111-0CL20 82111-0CL21 82111-0CL22 82111-0CM10 82111-0CM11 82111-0CM60 82111-0CM61 82111-0CM80 82111-0CM81 82111-0CN00 82111-0CN01 82111-0CQ90 82111-0CR00 82111-0CR10	Wire, Engine Room Main	Wire Harness

 

Note: (1) Although the involved vehicles are within the above production period range, not all vehicles in this range were sold in the U.S.

• Only vehicles in the above production range which were equipped with the wire harness that was assembled incorrectly due to a specific error in the design drawing are involved in this recall. Other Toyota/Lexus vehicles are not equipped with this wire harness.

 

3. Total Number of Vehicles Involved:

Total        : 183,397

 

4. Percentage of Vehicles Estimated to Actually Contain the Noncompliance:

100%

 

5. Description of Noncompliance:

The subject vehicles are equipped with LED head light assemblies which contain front turn signal bulbs with dual filaments.  Due to an error in the design drawing, the wire harness connected to the front turn signal bulbs was assembled incorrectly.  As a result, the incorrect filament in the dual filament bulb is used when the front turn signal or front hazard warning light functions are activated.  This results in decreased brightness of the front turn signal bulbs, causing the subject vehicles to not meet certain requirements in FMVSS No. 108, paragraphs S6.4.3(b) and S7.1.1.13.  If oncoming traffic is unable to notice the front turn signals or front hazard warning lights, it may result in an increased risk of a crash.

 

6. Test Results and Other Information:

After a Toyota employee observed that the turn signals on an involved Tundra vehicle were less bright than other Toyota vehicles, Toyota began an investigation into this issue.  Toyota identified an error in the design drawing of the wire harness connected to the front turn signal bulbs that would result in the brightness of the front turn signal bulbs being less than intended.  Toyota conducted testing to assess whether this condition may affect compliance with the requirements of FMVSS No. 108.

Testing of the subject headlamps equipped with front turn signal bulbs indicated that the brightness of the turn signal bulbs did not meet certain requirements in FMVSS No. 108, paragraphs S6.4.3(b) and S7.1.1.13 and on July 9, 2020 Toyota decided that the front turn signals did not comply with those portions of FMVSS No. 108.

 

7. Description of Corrective Repair Action:

All known owners of the subject vehicles will be notified by first class mail to return their vehicles to a Toyota dealer.  For all involved vehicles, the dealers will modify the wire harness connected to the front turn signal bulbs free of charge.

 

Reimbursement Plan for pre-notification remedies

As the owner notification letters will be mailed out well within the active period of the Toyota New Vehicle Limited Warranty (“Warranty”), all involved vehicle owners for this recall would have been provided a repair at no cost under Toyota’s Warranty.

 

8. Recall Schedule:

Notifications to owners of the affected vehicles will occur by September 13, 2020.  A copy of the draft owner notification letter(s) will be submitted as soon as available.

 

9. Distributor/Dealer Notification Schedule:

Notification to distributors/dealers will be sent by July 15, 2020.  Copies of the dealer communications will be submitted as they are issued.
