Manufacturer Honda
(American Honda Motor Co.)
Components ELECTRICAL SYSTEM, EXTERIOR LIGHTING
Potential Number of Units Affected 793
Loss of Brake Lights/FMVSS 108
Brake lights that do not work increase the risk of a crash.
Summary
Honda (American Honda Motor Co.) is recalling certain 2017 Acura NSX vehicles. Road vibrations may cause the metal screws that secure the printed circuit board for the high mounted center brake light to loosen and contact the circuitry, possibly resulting in the brake light fuse blowing and the brake lights not functioning. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, “Lamps, Reflective Devices, and Associated Equipment.”
Remedy
Honda will notify owners, and dealers will replace the center high mount brake light, free of charge. The recall is expected to begin November 6, 2018. Owners may contact Acura Client Relations at 1-844-682-2872. Honda’s number for this recall is B2B.
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.

AFFECTED VEHICLES
| Year | Model | Trim | VIN Range |
| 2017 | NSX | ALL | Check the iN VIN status for eligibility. |
BACKGROUND
There is an internal issue with the circuit board in the high mount brake light (center high mount brake light). This may cause all the brake lights to stop working, turn on several indicators, and the vehicle may not start. If the brake lights stop working, this may reduce the braking visibility from behind, increasing the potential risk of a collision.
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
Replace the high mount brake light.

High Mount Brake Light Drilling and Removal Procedure
NOTE
Use this drilling procedure only on the nuts that you could not remove.
- Place another fender cover over the roof, and secure it with masking tape. Apply masking tape to the C pillars surrounding the perimeter of the high mount brake light.
NOTE
Make sure the windows are closed and the fender cover fully covers the engine compartment area. The drilling process creates debris that may fall into the interior or the engine compartment.
- Close the hatch, and tape a protective cover to protect the hatch glass.
- Using the template provided in the kit (P/N 06100-T6N-A00), line up the template with the high mount brake light.
- Make sure the edge marked FR faces the front of the vehicle.
- Line up the LOCATING DATUM with the front left corner of the high mount brake light.
- Insert the four cardboard guides (included in the kit) between the high mount brake light and the template where the mounting bolts are located (as indicated by the shaded parts of the template).
- Make sure the front edge of the template contacts the cardboard guides, then secure the template with masking tape.
- Drill the pilot hole(s) in the high mount brake light.
6.1 Place a drill collar(drill stop) on a 3 mm drill bit. Secure the collar 11 mm from the cutting tip.
6.2 Carefully drill a hole in the center of the applicable holes marked on the template.
NOTES
- Only drill the holes where you could not remove the nut.
- The high mount brake light is made of thin, soft plastic. Do not use a lot of force as the drill bit will cut through the material easily.
- Do not drill deeper than 11 mm as you may damage the body.
6.3 Remove the template.
6.4 If you are drilling either of the outer nuts on the high mount brake light (holes closest to the C-pillar) follow these steps:
6.4.1 Install the two stop washers in the Rotabroach kit. Measure and confirm that the distance between the cutting edge of the Rotabroach bit and washers is 23 mm.
6.4.2 Create a soft depth gauge on the 14 mm Rotabroach bit by wrapping it with tape. Wrap the tape 11 mm from the cutting edge of the Rotabroach bit.
6.4.3 Carefully drill the hole to a depth of 11 mm.
NOTE
Drilling the outer holes deeper than 11 mm may cause damage to the body.
6.5 If you are drilling either of the inner nuts on the high mount brake light follow these steps:
5.6.1 Remove any tape from the 14 mm Rotabroach bit.
NOTES
- The distance from the cutting edge of the Rotabroach bit to the large washer surface should measure 23 mm.
- Drilling the inner holes deeper than 23 mm may cause damage to the body.
6.5.2 Carefully drill the hole to a depth of 23 mm (the large washer will meet the high mount brake light surface).
- Open the hatch.
- Remove the applicable nut(s) by placing a flat head (flat tip) screwdriver against the edge of the bolt head to hold it in place while removing the nut.
- Remove the high mount brake light.
NOTE
Do not pry up on the high mount brake light face. Carefully insert the appropriate trim tool under the high mount brake light.
9.1 Close the hatch.
9.2 Remove the high mount brake light.
9.3 Disconnect the connector.
- Vacuum any debris present from the drilling, and carefully remove the covers on the roof, the hatch glass, and the engine to prevent any material from falling into the engine area.
- Replace the two clips indicated below.
- Install the new high mount brake light.
12.1 Connect the connector.
12.2 Install the high mount brake light.
12.3 Install, and torque the new mounting nuts to 9 N·m (3.6 lb-ft).
