## NHTSA's summary

SSPD8 \- Check Engine Light ON with DTC P0126:00 \- WARRANTY EXTENSION For certain 2018\-2025MY CX\-5, 2019\-2023MY Mazda3, 2019\-2022MY CX\-3, 2018\-2021MY Mazda6, 2020\-2023MY CX\-30 that are equipped with the suspected coolant control valve, the warranty coverage for specific repair of the fail\-safe thermostat is extended to: 15 years \(180 months\) or 150,000 miles \(240,000 km\) whichever comes first, from the original warranty start date. CONDITION OF CONCERN: 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. Mazda Motor Corporation has made a significant repair change to TSB 01\-003/25 which also impacts Warranty Extension Special Service Program \(SSPD8\). Repair Procedure Update: Effective December 8th all repairs applicable to TSB 01\-003/25 or SSPD8 must follow the new repair procedure. The repair now replaces the thermostat with a dummy plug for the coolant control valve \(CCV\) along with a required software update for the PCM. Prior Repairs: Any repairs previously completed with the replacement of the thermostat or coolant control valve assembly does not require a re\-repair unless there is a verified failure following the diagnosis in the TSB. It is expected that there will be no further repairs made for this concern once the plug and software update has been completed. Therefore, a return visit for symptoms related to the TSB or SSP must contact the Technical Hotline for assistance. VITALLY IMPORTANT\!: There must be a “Software Update” record for the PCM when using MDARS or IDS. • MDARS \- If there is no Software Update entry in MDARS or the Collect Diagnostic Information \(ODR Update\) is not completed \(or both\), the vehicle will not be considered repaired and the warranty claim will be rejected. • IDS – Vehicles programed with IDS must Collect Diagnostic Data, and that data must be attached to the warranty claim. If the data is not attached to the claim, the vehicle will not be considered repaired and the warranty claim will be rejected, denied or debited. Failure to complete the above will require the vehicle to return to the dealership and be re\-repaired at the dealer’s expense with great inconvenience to the Mazda customer. Failure to perform the software update could also potentially damage the engine which would not be covered by warranty and would expose your dealership to the cost of repairs.

- [SA\-048\-26](/bulletins/11037006.md), 2026-09-04, Service bulletin: ENGINE. Some vehicle may exhibit the CHECK ENGINE light on with DTC P0524 \(Engine oil pressure control system: Oil pressure decrease\) and no abnormal engine noise. This may be caused by a malfunction of the oil pressure control valve \(located at the rear of the engine block near the oil filter\) due to machining contamination inside the electromagnet sleeve and the solenoid plunger remaining during manufacturing. This contamination is affecting the OCV operation when oil pressure control is requested by the PCM. REPAIR PROCEDURE Perform the WSM inspection for P0524.
- [01\-010\-26](/bulletins/11036688.md), 2026-09-02, Service bulletin: ENGINE. This bulletin supersedes the previously issued bulletin\(s\) listed below. The changes are noted in Red text. 01\-012/22 10/06/22 DESCRIPTION Some vehicles may exhibit accumulation of dried coolant \(1\) around the water pipe \(2\). This is caused by a gap between the housing and pipe due to a press fitting during the manufacturing process. The accumulated coolant is solidified and plugs the gap in high temperature environment and the seepage is stopped and does not progress. This is normal and does not require a part replacement, clean off the dried coolant from around the pipe with a wire brush. REPAIR PROCEDURE 1. Verify the customer concern. 2. If the above condition is experienced, remove the accumulated coolant around the pipe \(1\) with a wire brush etc. NOTE: Perform the procedure on the vehicle. No need to remove the water pipe and hoses.

- [SA\-041\-26](/bulletins/11034447.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM; ENGINE. This SA supersedes the previously issued SA\(s\) listed below. The changes are noted in Red. SA\-061/25 12/17/25 DESCRIPTION If you encounter any type of electrical concern \(e.g, dead battery, engine no start, DTC\(s\) stored...\), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC\-2 \(battery discharge/DTC stored\) 2. Devices plugged into the 12V outlet 3. GPS tracking device \(engine no start/battery discharge\) 4. Dash cam \(DTC stored\) 5. Non\-certified USB cable \(Apple Carplay™/ Android Auto™ will not connect\) 6. Over\-sized wheels/tires \(incorrect GPS location\) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC\-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC\-2 connection. The aftermarket device may cause DLC\-2 female terminals to spread open.
- [09\-019\-26](/bulletins/11034436.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM; UNKNOWN OR OTHER; ENGINE. This bulletin supersedes the previously issued bulletin\(s\) listed below. The changes are noted in Red. 09\-012/21 12/13/21, 06/10/21 and 04/27/21 DESCRIPTION Some customers may experience all of following symptoms: The door lock/unlock operation will not work using the remote transmitter button. 1. The door lock/unlock operation will not work using the door lock/release touch sensor. 2. The engine will not start using the ignition switch. 3. The transmitter operates by itself. 4. The key battery drains faster than usual. 5. Symptoms 1\-3: This may be caused when excess load is applied to the remote transmitter, deforming the electrical terminals and creating poor contact with the battery. To eliminate this concern, the structure in the remote transmitter has been modified to reduce the deformation of the electrical terminals. Symptom 4\-5: This may be caused when excessive load is applied to the remote transmitter, creating a gap around the gasket where moisture enters and corrodes the circuit board which in turn drains the key battery faster than usual. To eliminate this concern, the thickness of the case wall on the gasket mounting surface has been increased and the bonding strength of the components has been improved to prevent deformation. REPAIR PROCEDURE • If the battery is bad or installed incorrectly, replace the battery and/or install it correctly. • If the remote power saving function is off and the battery is good and installed correctly, replace the defective remote transmitter with a modified one according to the instructions on MGSS \(IMMOBILIZER SYSTEM\-RELATED PARTS PROGRAMMING\). NOTE: DO NOT replace other remote transmitter\(s\) for the vehicle if they not experiencing an issue.
