2020-2023 CX-30 – Check Engine Light ON with DTC P0126:00
Dear Mazda Dealer Colleagues,
Mazda Motor Corporation has decided to conduct a Special Service Program (SSP) to extend the
warranty coverage for a specific repair of the fail-safe thermostat in the coolant control valve on certain
CX-5, Mazda3, CX-3, Mazda6 and CX-30 vehicles that are equipped with the suspected coolant control
valve. The warranty coverage for a specific repair of fail-safe thermostat has been extended to 15 years
(180 months) /150,000 miles (240,000 km) whichever comes first, from the original warranty start
date.
Concern Outline:
On certain subject vehicles, the check engine light is illuminated with DTC P0126:00 (Thermostat stuck
open) stored in memory and one or more of the following symptoms may occur:
Engine takes longer to warm up.
Engine temperature gauge fluctuates.
Low coolant temperature indicator (blue) light stays on longer or turns on while driving.
Poor heater performance, especially at idle.
This is a warranty extension for the specified repair only. Inspection and replacement of non-failed parts
will not be eligible for reimbursement under this SSP to the dealer or customer. This program extends the
warranty period for actual failures due to defects in workmanship or materials in accordance with the
Mazda Warranty Policy and Procedures. If a customer arrives at your dealership with the concern
described, please repair under this Special Service Program.
Parts Ordering:
Dealers can use the Limited Parts Ordering (LPO) screen on eMDCS to order the repair parts. There is a
weekly maximum allotment, which is displayed on the LPO screen. The LPO process and weekly quantity
limit helps to ensure our supply is balanced across the U.S. dealer network and available for all

customers.
Owner Notification:
Due to the size of vehicles in this campaign, owners of subject vehicles will be notified by first class mail
over a 3 week period beginning in mid-November through early December, 2024.
Customer (Vehicle Owner) Reimbursement:

to receiving this notice, they may be eligible for reimbursement of reasonable repair expenses based on
Mazda’s repair standards. For vehicles purchased in the USA, please advise the customer to visit
www.mazdareimbursement.com on or after November 30, 2024 and follow the online screen prompts
