Good afternoon all,

This is Kevin and my first post. My wife's 2016 350 started up fine today but every warning light in the instrument cluster came on and stayed on. Nothing I have tried to rectify this has solved the issue. I thought it may be a battery issue but after not finding a word about where that is located I checked at the jumper posts and that seems to be fine. Does anybody have any suggestions?

Thanks for your time and assistance,

Kevin

Here is what I found out today if anybody else has this issue. The battery had a dead cell which is what tripped the lights to all come on. Our local dealer did not have an OEM battery in stock and stated they were on back order for 3 weeks and they had no idea on when they would get them in. I replaced it with a new battery from Autozone. They only showed one battery for that vehicle and after getting it home I found it was 1.5 inches longer than the OEM. That made a huge difference as if I could have gotten it into the compartment it would have been sitting on the hold down bolts for the retainer clamp. The new battery didn't clear the idiot lights so it had to go into the shop. The mechanic told me that if you replace the battery with other than an OEM battery you have to use a code reader to tell the computer you are changing batteries before you disconnect it. I hope this helps anybody doing a DIY batt swap.

There is (2) battery one under the passenger front seat that's the main battery. There is a second battery for Auxiliary battery. If it's not in the rear hatch inside the rear panel I think it was the right side. Then the other location would be under the rear seat driver side.
