2017~2021 Maintenance Reminder/Oil Change due - last Oil Change @ 3,179 mi

:
2018 Mazda CX-5 GT
My first oil change per the thread title was 9/28/2019. I set the maintenance reminder to Flexible as suggested instead of by mileage. In June 2020, I had the PCM update for the CD Recall. The maintenance reminder started displaying the wrench within the last month or so and while driving for vacation, it said service was required. I wasn't sure which service since it could've been tire rotation or oil change. Once about 7,500 mi came around, it said oil change due.

By the end of our trip, the ending mileage was 8,716. So we probably drove about 1,500 miles.

I tried to reset the maintenance reminder in the parking lot during a rest stop and it didn't work. Due to Covid, I've only been driving the car once a week for the most part to charge the battery and run the car - all trips were about 15 miles each to prevent oil dilution.

Current oil is Mobile 1 Advanced Fuel Economy with a M-108A filter. I don't believe an oil change is due given the type of driving I've been doing (no short trips) and having to clear the maintenance wrench twice is irritating. Any suggestions?

Thanks in advance!

There’re 3 maintenance schedules, Maintenance、Tire Rotation、Oil Change, in Maintenance Monitor on your infotainment screen. You can tell the difference among the 3 by notification message. Or you can go to Maintenance Monitor on infotainment screen to see which one triggered the maintenance reminder message. Have you done the reset to all three? You have to do the reset with ignition on, but the engine is NOT running.

The Flexible OCI is UP to 7,500 miles or 12 months based on your driving habit and condition for gen-2 CX-5. If your first oil change was made at 3,179 miles on 9/28/2019 and reset the Oil Change schedule to Flexible. And your current mileage is 8,716 miles plus some since October. Your wrench indicator should be on around 9/28/2020 no matter how few the miles you’ve been driving. There’s nothing wrong with it when you saw the wrench indicator during your trip.

Based on the TSB there’re 2 separate Flexible OCI remainders. But you only need to do the reset in entertainment screen which will reset both. If yours can’t, you need CMU software update.

Once you reset the Flexible oil change schedule, it should display 7,500 miles for gen-2 CX-5, or 100% for gen-1 2016(.5) CX-5. Your reset procedure may have been out of sync between using the trip meter switch to reset the powertrain control module (PCM) and using the infotainment to reset the connectivity master unit (CMU). Check 2 related TSBs for further details and you may need perform at least the TSB 09-037/18 if necessary.

TSB 09-037/18 - OIL MAINTENANCE MONITOR RESET CONCERNS

IMO I wouldn’t use one-size-fit-all Mobile 1 M-108A filter listed for both SkyActiv-G 2.5L and 2.5T, whereas Mazda uses 2 different OEM oil filters for these 2 engines.

Thanks YRWEL52. I booked an appointment with a reputable independent shop to do this oil change since due to the pandemic, I don't have access to my parents' garage. I have a WIX 57002 filter so I'll try using it instead of my extra Mobile 1 108A filter.
