Background
• Toyota
has received reports that certain 2008 model year Sequoia
vehicles operated in specific cold climate areas (Cold Climate
States) with high road salt usage may exhibit more-than-normal
corrosion to the vehicle’s frame.
• Toyota
investigated these reports and determined that the frames in
some vehicles may not have corrosion-resistant protection sufficient
Tacoma shown in example.
for use in these areas.
• This combined with prolonged exposure to road salts and other
environmental factors, may contribute to the development of more-than-normal rust in the frame of some vehicles.
• This condition is unrelated to and separate from normal surface rust which is commonly found on metallic surfaces
after some years of usage and/or exposure to the environment.
The following information is provided to inform you and your staff of the program notification schedule and your
anticipated degree of involvement.

Warranty Enhancement Program (WEP) Details
This Warranty Enhancement Program provides enhanced coverage to the vehicle’s “New Vehicle Limited Warranty”
as it applies to frame corrosion. The specific condition covered by this program is rust that satisfies the Rust
Perforation Standard as per the Settlement Agreement. If the condition is verified, the vehicle will be repaired with
a new frame under the terms of this Warranty Enhancement Program.
•
The coverage offers the latter of 12 years from the Date of First Use (DOFU) or 1 year from the date of final
approval (5/21/2017).
This coverage is for warranty work performed at an authorized Toyota
dealer only. It is subject to the terms of the Settlement
Agreement and conditions set forth in the New Vehicle Limited Warranty Section of the Owner’s Warranty Information booklet, except
where conflicting with the Settlement Agreement, in which case, the Settlement Agreement controls. For example, damage from
abuse, an accident, theft and/or vandalism is not covered by the New Vehicle Limited Warranty or this warranty enhancement.
Warranty Enhancement Coverage:
If a customer believes their vehicle has been operated in cold climate regions of the United States where high road
salt is frequently used and/or a customer is concerned that their vehicle’s frame has more-than-normal corrosion,
Toyota
dealerships are requested to inspect the vehicle’s frame for corrosion using the Court-ordered Frame
Inspection and Replacement Protocol. Based upon the results of the inspection, dealerships are requested to do one
of the following at no charge to the vehicle owner:
•
•
•
For warm climate states, if the vehicle’s frame passes Toyota
’s inspection, no further action is required.
For Cold Climate States (District of Columbia (DC), CT, DE, IL, IN, KY, MA, MD, ME, MI, MN, NH, NJ, NY,
OH, PA, RI, VA, VT, WI, and WV), if the vehicle’s frame passes Toyota
’s inspection, the vehicle may be eligible
to have Corrosion Resistant Compound (CRC) protection applied. This will be applied under a separate
Limited Service Campaign (LSC).
For all states and territories, if the vehicle’s frame meets or exceeds the standard for frame replacement, the
frame will be replaced at no charge to the customer.
