2022 Mazda MX-5

On two occasions the vehicle (which is silver--more about that below) has suddenly and without warning activated its emergency braking. The most recent occasion was summer of 2023. On a clear, dry afternoon the system activated while I was at speed on the Suncoast parkway approaching an automatic toll arch. Fortunately there were no other vehicles nearby. I pulled to the side of the road and turned the car off and on again to attempt to clear whatever glitch had happened. The incident was so dramatic I've actually forgotten what the prior incident was. I remember one reason that was mentioned in the manual was a dirty windshield, and that was not the case at that time. I have *never* experienced a justified engagement of the system despite driving in heavy traffic for more than half an hour twice each weekday. I was put in mind of the incident by a recent recall of Genesis G90 sedans painted silver, like my car. Apparently the paint reflected radar and set off the emergency braking system. I surmise there may have been some radar-emitting device in use temporarily on or around the toll arch.

Manual transmission synchronizers fail, causing erratic gear shift operation and the inability to change gears, which could result in an accident. The ND Mazda Miata Owners Group on Facebook has polled its owners and found a 10% failure rate of manual transmissions among owners in the group who required replacement of the transmission. On [XXX], at approximately 20,000 miles on the odometer, my 2022 Mazda MX-5 Miata experienced a grind from the transmission while downshifting to third gear at city speeds. I alerted Mazda North American Operations on May 30, 2024. On [XXX], the gearbox began grinding during downshifts into second gear. My car entered service at Mazda of Knoxville around June 3, 2024. Mazda of Knoxville confirmed that the vehicle required transmission replacement. Parts were not immediately available, and due to a work assignment in Des Moines, I had to drive the vehicle to Iowa. On [XXX], I noticed fourth gear began grinding during upshifts. On June 10, 2024, the vehicle entered Ramsey Mazda of Des Moines for service. Mazda North American Operations did not immediately approve repair, stating that their engineering department requested information from Mazda of Knoxville and is reviewing the claim. I am still awaiting an update. The vehicle is available for NHTSA inspection at Ramsey Mazda in Des Moines. Manual transmission failures are a serial problem for the ND-chassis Mazda MX-5 Miata since the 2016 model year, with significant failure rates reported among owners for 2016, 2017, 2022 and 2023 model years. Symptoms begin with difficulty upshifting to third gear that feels like a blocked shift gate. Grinding in the transmission soon leads to complete failure, which causes loss of throttle control and could result in an accident. My inability to select the correct gear impeded my ability to maintain safe speeds. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Hi Team, I bought a Mazda Miata MX5 RF 2022 and its user manual states the vehicle is to come with LATCH system to attach the child car system. However the LATCH hooks are not present in that car seat. 1) My understanding is that is a legal requirement to provide the LATCH system. Could you please clarify if that is the case? 2) If there is a discrepancy between what is specified in the user manual and what is actually in the car (for the Child Seat LATCH), will the manufacturer be required to install it for me? 3) It will be helpful if you can share the options I have to get the Child Car Restraint installed?

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.

DESCRIPTION Some vehicles may exhibit scratches (1) on the rear of the seat back bar garnish (2) from contact with the convertible top (3). Due to assembly variations, the clearance between the seat back bar garnish and the convertible top is too small on some vehicles. REPAIR PROCEDURE 6. Install the seat back crossmember assembly from the vehicle according to the instructions on MGSS online or the Workshop Manual (section 09-10 SEAT BACK CROSSMEMBER ASSEMBLY REMOVAL/INSTALLATION). 7. Reinstall the rear seat back bar garnish while twisting the garnish so that the garnish can be kept closer to the seat back bar and away from the convertible top (for both left and right sides).

This Service Alert supersedes the previously issued M-Tip(s) listed below. The changes are noted in Red text. MT-002/19 09/30/19 and 12/19/19 DESCRIPTION If an engine assembly is replaced after a catastrophic internal mechanical failure, clean the intake manifold internally before installing a replacement engine assembly. If the intake manifold is not cleaned properly, the replacement engine may fail prematurely. Metallic debris from the old engine (with catastrophic internal mechanical failure) may rest inside the intake manifold. When the new engine assembly is installed, debris in the intake manifold will be ingested into the new engine and cause internal damage. Clean the intake manifold internally to remove any debris from old engine before installing the new replacement engine assembly. If the intake manifold cannot be properly cleaned internally, replace it.
