2015 Mazda CX-5

With a heavy downpour of rain the bsm flashes off, then after sitting for a few hours the car battery dies and the key fob is not recognized in the vehicle. Took it to a dealership and it stopped doing it. Code that are thrown have to do with some computer communication failing. I have had the car die on me 4 times in the last year that I’ve had it.

I was near a red light and applied the brakes, but the car accelerated and ran into the truck stopped in front of me. This happened around May of 2024. I took the car to the Elk Grove Mazda dealer. They ran diagnostic and road tests but found nothing wrong. The car had the same problem again sometime later inside my garage. The car rammed into the drywall while I tried to stop by pressing the brake pedal. I took the car to the AAA repair shop in August 2024. They spent three days, and they told me they found a problem with the "steering angle sensor." It was 22 degrees off calibration. They reset the sensor, and the car ran better. However, the car acted again after some driving. It tries to accelerate while I apply the brake pedal near a stop. I took the car back to the AAA shop, but they did not find any problems in a whole week. I still drive this(my only) car, but extra careful, keeping a longer distance between cars in front of me and braking ahead few times ahead of any stop.

While driving on the freeway the check engine light came on. I was able to drive the car home the remaining 20 minutes but there was some noticeable difficulty accelerating. When I went to turn on the car later that day the engine would not turn over and there was an audible rattling/chugging sound and the car itself shook. I was unable to get the car to start and the check engine light remained on. I had AAA check the battery the next day and confirm it was not a battery issue and a diagnostic revealed the P0192 code. AAA towed it to their shop where it was confirmed by the manager mechanic that the issue was with the high pressure fuel pump and that it was causing an issue with the low pressure fuel sensor as well. The mechanic was unable to determine what caused the pump to fail and has quoted me nearly $2000 to fix it. After some searching online it has become clear that this is an issue many other Mazda owners have faced and that is even a recall for the pump for years and makes from Mazda due to a known issue with DENSO fuel pumps causing this exact issue. Despite this being known and DENSO having admitted issue with fuel pumps in cars dating back to 2013, Mazda has not recalled the vast majority of the cars that could be affected. From information I've gathered, it is entirely possible that my vehicle could have just stopped running in the middle of the freeway due to this issue which obviously would have put me in great danger of an accident. To summarize: Low pressure fuel sensor and high pressure fuel pump with error code P0192 are cited as the issues. It's possible this issue can cause the car to stop running with no warning, which would be extremely dangerous especially on the freeway. The problem has been reproduced and confirmed by a AAA mechanic shop. The vehicle has been inspected by the AAA mechanic but no others. The check engine light came on but was not clear how extreme the circumstance was.

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-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.

This Service Alert supersedes the previously issued SAs and bulletin(s) listed below: The changes are noted below in red. SA-010/23 02/09/23 DESCRIPTION Some customers may experience one or more electrical malfunctions after a vehicle body repair. A newly painted fender stay (2) may be causing a poor front harness (1) ground connection. The front fender stay (2) newly painted surface at ground point (3), where attachment bolt (4) is seated, may create a poor front harness ground connection. NOTE: DO NOT paint ground point (3) attachment bolt (4) is seated. NEWLY INSTALLED FRONT FENDER STAY NOTE: CAUTION: If the bolt (4) contact area (3) is painted when the front fender stay (2) is newly replaced, it could cause a malfunction in the PCM. Before painting a newly replaced part, protect the bolt (4) contact area (3) with masking tape (5) as shown in the figure.
