2023 ER Lariat Heater Went Out Just as Winter Hit

[Adventureboy]

I've had to add coolant to both my Lightning and my wife's MME. Both were right at the bottom and I expect there is a safety switch that won't allow the heater to kick on if the coolant is low, so I agree with checking that first.

You'd think there would be a low coolant warning/message display ??

Just had a thought...purchase an electric space heater...maybe it will be more efficient than the native heater...

Great recommendation we used space heaters in Alaska to prevent plastic interior cracking in the winter. They work great didn't really heat anything at 40 below but it did prevent cracking

You would think. No warnings on either of mine and the Lightning tank was pretty much empty. Given @Buio and @chrisvitek1 's experience, it doesn't appear to have a low coolant warning system, unless you consider a non-functioning heater as the warning.

I have it on my weekly watch list along with topping up the washer fluid. It's easy to glance at it in the Lightning when the Frunk is open. Not so easy on the MME as I need to remove a trim panel. I haven't had to add to either since the first time.

It seems unlikely a high voltage electric heater would last long if it was dry.
