or 50,000 miles (whichever comes first), we at Lexus care about the guests’ ownership experience. Lexus is providing coverage for repairs
related to excessive corrosion to the wire harness connections at the Rear Motor Generator. Excessive corrosion can cause AM Radio static
during certain drive cycles, or the vehicle may not start.
The following information is provided to inform you and your staff of the program notification schedule and your degree of involvement.

on certain 2022 -2023 Model Year NX350 & 2022 NX450H+ vehicles. The specific condition covered by this program is excessive
corrosion at the connector of the HV Floor Under Wire Harness and Rear Traction Motor Cable. If the condition is verified per Lexus
inspection criteria, the vehicle will be repaired or have the affected wire harness/cable replaced under the terms of this Customer Support
Program.

Salvage Title Vehicles
There is no New Vehicle Limited Warranty coverage or non-emission CSP coverage for vehicles that have been branded as salvage, total
loss, true mileage unknown, or similar title under any state’s law. Nonetheless, every attempt should be made to complete an open emission
related CSP when circumstances permit, unless noted otherwise in the CSP dealer letter.
For complete details on this policy, refer to Lexus Warranty Policy 4.17, “What Is Not Covered by The Lexus New Vehicle Limited Warranty”.
Guest Marketing
Direct marketing of this Customer Support Program is strictly prohibited pursuant to the Lexus Warranty Policy 5.22, “Warranty
Solicitation.” Non-compliance with this policy may result in a claim debit.

contact only to the media.
Parts Ordering Process
Parts for this campaign may be either required to be ordered in Campaign Part Order Request (CPOR) on Service Lane or placed on Manual
Allocation Control (MAC) due to potentially limited part availability. Please check the CPOR/MAC report on Dealer Daily for the most upto-date parts ordering information. Dealers can identify which parts ordering method to use by reviewing the parts information section of
Dealer Daily and checking for a MAC code on the part numbers below. For MAC code C, order through CPOR. For MAC code D, refer to
the MAC report for further instructions.
As this is a Customer Support Program, the condition MUST be verified by inspecting the vehicle. Therefore, dealers SHOULD NOT
increase their stock of related repair parts. Dealers are requested to only order parts for vehicles experiencing this condition only. DO NOT
ORDER FOR STOCK. As always, if a guest experiences the condition described, dealers should conduct appropriate diagnosis and order
the applicable parts.

If an owner thinks they are experiencing the AM static condition described in this Customer Support Program, the owner can
perform a simple stationary test.
1. In a safe area, start the vehicle in Park.
2. Tune the radio to a known AM station in your area.
3. Listen to the radio and take note of the sound quality.
4. After confirming the sound quality, place the vehicle into Reverse or Drive with your foot on the brake for 3
seconds. Then place the vehicle back into Park.
5. Repeat step 4 for an additional 2 times.
6. If the vehicle has the concern, the static will start exactly when the vehicle is placed into Drive and/or Reverse.
The static will then go away when placed back into Park.
Note: If you are not a regular listener to AM radio, static can be considered normal depending on the reception
and as you are driving. This static is not related to this condition.
If an owner believes the vehicle is affected after performing the AM Static check, they should contact their local Lexus dealer for an
appropriate diagnosis.
