Anyone else having intermittent issues with heat? I had a 6 hour drive in -20c with no heat in December. The next day, heat worked fine. A few days later, no heat. Sometimes it comes back after I park and other times it's out for the day and back the next. I have yet to figure out a pattern to it.

 

Probably a failing HV coolant heater. Is this on your '19 or the '24?

 

It's on the '24

 

In that case it should have the latest one, but it should also be under warranty, sounds like it's time for a dealer visit. I have seen a few HVJB failures on the newer cars, but it's nothing common. The late ones are actually quite reliable (for a JLR product), which is why I leased one for the wife when they had the strong program late last year.
