After the dealer replaced my 2016 F/R battery [5 years old] to fix non-functioning Intelligent stop start, I now realize the Dynamic mode & Exhaust switches plus the remote start function are not working at all. Remote Start gives some dash lights and seems like it is going to start but fails every time. Unlock etc. all function remotely, go figure. Dealer is baffled thought Battery was weak but it is GOOD. Anyone got a suggested remedies??? Intelligent Stop/Start is working well.....

 

Fixing one problem only to create three more? My only suggestion would be to make the dealer do the right thing.

 

mate, you've fixed the hated stop start and broken the cars best feature, the dynamic mode and loud exhaust, I don't think you faired well in that trade off, all jokes aside, I wouldn't be surprised if it's still battery related or some short or electrical problem, try putting in a new battery and letting the system reset and see if it fix's itself, I've been told the battery was "good" as well when I had some weird electrical issues, ( hazards wouldn't turn off) and after 2 visits... Drum roll please... It was a battery.

 

I agree with Stormtrooper. These cars are very sensitive to minute battery voltage drops. A lot of places don't understand how to "properly" test batteries. If they only measured the voltage of the battery, then they really didn't know the condition of it. If they replaced it with a new AGM, did they fully charge the new one before putting it into service?

 

yep, it's kinda ridiculous how little some of the techs care or know, now I'm not saying I can do better then the techs, I can't... but I would check another dealer or try another battery because its insane the effect low battery voltage has on these cars.
