Heavy condensation is occurring inside the driver side headlamp. A quick google search shows this is a common problem among Mazda owners and Mazda will not cover the repair. I am unable to get a Massachusetts state inspection sticker due to this.

Was driving my grandchildren home when an alarm that I had never heard before started sounding and BRAKE! showed up on the heads up display. The car came to a stop out in the middle of the street even though there was nothing in front of or around the vehicle. It was a good thing there was not a car behind me or they would have rear-ended my vehicle and we or the people in the car that hit us could have gotten seriously hurt. I took the car to the dealer and they did a diagnostics check and said no codes came up so there was nothing wrong with the car. They actually told me that when and if it happens again to videotape it for proof.

I WAS SOLD A VEHICLE WITH "NEW" TIRES. I'VE ONLY HAD THE VEHICLE ABOUT 6 MONTHS AND FOUND OUT THE TIRES WERE MADE IN 2011 AND STARTING TO DETERIORATE SO I HAD TO BUY ACTUAL NEW TIRES. I DID NOT HAVE AN ACCIDENT BUT FEEL THERE COULD HAVE BEEN A TIRE BLOWOUT. LUCKILY I HAD RUN OVER A BOLT AND WAS TRYING TO GET A TIRE REPAIR WHEN THE TIRE PLACE TOLD ME ABOUT THE BAD CONDITION OF ALL FOUR TIRES. THE DEALERSHIP FIRST DID NOT BELIEVE ME BUT WHEN I SHOWED THEM A PICTURE THEY SAID THEY CAN SELL TIRES UP TO 8 YEARS OLD AS NEW IF THEY WERE NOT PREVIOUSLY ON A VEHICLE. I DON'T KNOW IF THAT IS TRUE BUT IF THE TIRES WERE STARTING TO DRY ROT IT SEEMS LIKE A BAD IDEA AND CERTAINLY UNETHICAL IF NOT ILLEGAL.

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.

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 01-008/23 06/05/23 Some vehicles may exhibit rattling noises from the engine compartment and oil leakage from the drive belt auto tensioner. This may be caused by insufficient sealing at the drive belt auto tensioner damper when the auto tensioner fully operates under both high ambient temperature and high load conditions. To eliminate this concern, the shape of the drive belt auto tensioner damper has been changed. REPAIR PROCEDURE If the tensioner is found to be "No Good" after completing the Drive Belt Auto Tensioner Inspection, replace it with a modified part according to the instructions on MGSS online:

DESCRIPTION Some vehicles may require the replacement of a damaged VIN plate or vehicle certification label. To obtain a replacement VIN plate (bulkhead-mounted and visible through the lower-left area of the windshield), contact DAG (Dealer Assistance Group) using VIN Plate Request Form available on One Mazda. To obtain a replacement vehicle certification label (located on the B􀀀pillar or front door), contact your assigned DSM (District Service Manager) to place the order. If DSM contact information is not available, refer to the Dealer & Field Contact Directory.

This Service Alert supersedes the previously issued SA listed below: The changes are noted in Red. SA-011/24 02/12/24, 06/06/24, 07/29/24 DESCRIPTION Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers. SCHEDULED MAINTENANCE Refer to the applicable Workshop Manual or Owner's Manual for vehicle -specific manufacturer scheduled maintenance. Workshop Manual - Refer to section 00-00 SCHEDULED MAINTENANCE. Owner's Manual - Refer to section 8 Maintenance and Care. b. Note: Please refer to the information below outlining the services not included in Mazda's Factory Scheduled Maintenance: IMPORTANT: Recommending fluid flushes when not necessary can lead to customer confusion and dissatisfaction. Fluid flushing for preventive maintenance purposes is strongly discouraged, unless otherwise specified in a published procedure (Owner’s Manual, Workshop Manual, Technical Service Bulletin, etc.).

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.

This Service Alert supersedes the previously issued M-Tip(s) listed below. The changes are noted in Red text. MT-003/22 03/02/22 DESCRIPTION Some customers may complain about a tapping or knocking noise coming from the rear seat after fuel fill. The concern will likely occur if the fuel tank is overfilled (more fuel is added after the fuel pump nozzle shuts off automatically) or filled up normally in high ambient temperatures and the fuel expands. No repair is needed. Explain to the customer not to continue filling after nozzle shut off.
