Hi all, I have a 2013 GS 350 F Sport with about 55K miles. I don't drive the car often, and have lately noticed several minor issues, and am wondering if an old battery might be responsible.
The battery was replaced in 2018, and starts fine and seems in every way fine. But, all these things have cropped up:
1. TPMS is wacky...shows a flashing tire despite no issues with the tire inflation. No longer shows any values, so I have to check the old fashioned way. I've reset the thing, but to only temporary effect.
2. The clock stopped keeping correct time.
3. The audio system sometimes refuses to show IPod setting, and sometimes turns itself off for no reason. Also, when I turn the car off and restart it goes to some other selection...like FM or Satellite, not what I was listening to.
Anyone had these symptoms...I'm thinking that the battery might be at fault?
Thanks, Joe

 

I think battery is definitely responsible for some of those issues.... assume you know how old the current battery is.
If it's 4-5 years old might be worth a change.

As far as the TPMS issue, I would think it's possible one (or more) of the batteries in the stems might be at the end of their lives(10 yrs now).and causing that glitch

 

Thanks, I'll go ahead and change it.
The TPMS are only a couple years old. I didn't like the wheels on the 2013 F Sport so I replaced with some new F Sport take-off wheels/tires from a 2020 car a couple years ago. So, they should still be OK. Hopefully, the battery will fix these issues. Thanks.

 

Tpms is flashing because the ECU can’t read at least one sensor. The battery either died or they weren’t properly relearned when you swapped the wheels. As far as the clock lots of us had issues with the time being wrong. There is an easy fix if you search clock.

 

Thanks. TPMS worked fine for two years. Only after I hadn't driven the car for two or three months did it start acting weird. Battery was always fine, although it is five years old. Its always started without hesitation and shown no symptoms of needing replacement. But, I suppose it should be replaced just for age.
As for the clock, I searched but was only able to find fixes that required removing the clock and fiddling with a magnet or something. Not an easy fix for me...LOL. Is this what you meant? Thanks.
