2021 Mazda CX-3

The instrument cluster in my 2021 Mazda CX-3 failed at approximately 50,000 miles. While driving, the vehicle displayed multiple warning lights, including Dynamic Stability Control (DSC), Smart City Brake Support (SCBS), traction control, and front camera/safety system warnings. These safety systems became unavailable due to the instrument cluster failure. An authorized Mazda dealership inspected the vehicle and attempted to reprogram (re-image) the instrument cluster, but the repair was unsuccessful. The dealership confirmed that the instrument cluster had failed internally and must be replaced. The failed component is available for inspection. Mazda Customer Experience has confirmed that the replacement instrument cluster is on national back-order and has been unable to provide any estimated availability date. As a result, I am required to continue driving a vehicle with disabled safety systems or leave the vehicle unusable for an indefinite period. I am concerned that a failed instrument cluster can disable important safety systems, including stability control and forward collision mitigation functions, and that replacement parts are unavailable. I am submitting this complaint because this appears to be a potential safety-related defect

All of the issues listed in Mazda Technical Service Bulletin 06-001/20, however this bulletin does not cover my model. Inspected by dealer, possible solution intended to be relubrication of the worm gear/worm shaft in the steering assembly. Issue presented itself in the last year and is most present while driving at high speeds, above 45 miles an hour.

The Mazda CX-30 2021 I purchased from Mastria Mazda in Raynham, Massachusetts has a steering problem that is a significant safety concern. The steering wheel has resistance that can most notably be felt at highway speeds (around 65 mph). When making small corrections to the steering wheel to stay in the lane the steering binds and then releases with further force ultimately resulting in overcorrections. The steering binds and then releases and is not fluid as any car should be. An apt analogy would be opening a new water bottle, when you twist the cap, you get resistance along the plastic perforations and with further force the cap releases and turns quickly. This is the best way I can describe the issue. This car is dangerous at highway speeds. An environment where a crash could be catastrophic. This issue needs to result in a recall immediately.

Having the exact same issue as was outlined and allegedly repaired in the prior service bulletin 06-001/20. Obviously this bulletin only applies to vehicles up to model year 2020. I have checked the model number on the steering motor to determine that it is the "updated" design. Obviously, the issue has not been addressed properly by Mazda.

Subject: Update – Campaign Warranty Claim Response Enhancements – Modules Not Repaired for Certain Campaigns Dear Mazda Dealer Colleagues, On October 28, 2026, a change was implemented in the warranty claim response screen to provide precise information for all campaigns requiring module programming or module replacement subject to the LECS system software checks. As previously announced, some claims were automatically rejected with the Edit code JN1 – One or More Modules Are Not Updated when submitting a campaign warranty claim. This response was based on the session file received from MDARS or MDARS II at the dealership and the VIN on the claim submitted. This change provides additional Related Information which enhances the edit code information. This information allows the dealer to correct the error without contacting Warranty or Hotline. Edit code JN1 now contains the actual module name and the software version that was collected from the car and what the minimum required software needed to be for the claim. Using this information, the technician can now identify the exact error or errors and correct the concern.

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted below in Red. 09-038/24 08/08/24 NOTE: This service information is NOT applicable to 7th generation Mazda vehicles because the odometer data is stored in the BCM. DESCRIPTION In accordance with Federal regulations, follow the procedure listed below when replacing a speedometer. NOTE: Tampering with a motor vehicle odometer is strictly prohibited by Federal, and State laws. It is the dealer’s responsibility to comply with Federal, State, and local laws concerning odometer and related documentation requirements when providing a repair or replacement. Mazda vehicles are manufactured with tamper-proof speedometers.

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

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.

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.

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.

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.
