2014 6 with numerous issues
 

Good afternoon All,
I just joined the forum looking for some solutions to some weird issues that have popped up. I purchased a 2014 with 16000 miles back in Sept. 2018. The car has been a dream to drive with no issues until now. Here is what I am experiencing:

1. The BSM Off light is a constant flash on the cluster.
2. The Air Bag Light blinks once then followed by 8 more flashes.
3. The Fob light on the cluster is red.
4. On Saturday 6/8, I filled the tank up to 14.8 gallons and after driving for about 30 miles the check engine light appeared with a PO463 code on the Fuel Level Sensor High Circuit. I cleared the code with my OBII and currently have driven 94 miles total since the fill up.
5. My gas gauge shows a full tank and then shows a half a tank after all the above lights illuminate.

I am heading to Advanced to get the battery checked but I wanted to see what the forum had first.
Many Thanks., Kevin "FNG"

1) Will require a diagnostic scan
2) Will require a diagnostic scan
3) Remote battery may need replacing. Anything below 3.00v is bad
4) Will require a diagnostic scan
5) Think there was a software issue with the FBCM

Thank you Grim_Reaper, I did replace the FOB Battery with a brand new Energizer 2025 and the red light went away. I scanned the system with my Actron CP9135 and pulled the PO463 code, which was cleared and has not returned. No other codes were found after the scan was completed. Yesterday 6/11 the BSM Off light was not flashing and neither was the Air Bag Light and the Red FOB light. This morning all the lights came back to life along with the Amber Start Engine light. I did go to Advanced and conducted a battery test. The reader shows 12.7V and I was told by the employee that the alternator and starter were both working properly after various load tests (AC on Max, Radio On, etc.). I will be heading to Carmax for an evaluation.

Since my last post, I purchased the BlueDriver OBD II reader. For a couple of days, I did not see the Airbag light, BSM off Flashing light and the Check engine light. I was able to pull the following codes from the Bluedriver: PO463 (possible Fuel Gauge Sensor replacement), B00D5 (PAD seat belt sensor) and U0447 (related to the Fuel Sensor). I haven't had an opp to get to Carmax as they will most likely send it to a Mazda Stealership. I do have to go to the stealership for a Parking brake recall on my 2014 Six and I did notice within the recalls that 3 others were found for Electrical, Fuel System and Tires.
