Heater problem

Has anyone ever had a heating problem? I live in a cold area (-10C to-20C) and the thermostat rises only very VERY slowly. The engine reaches its optimum temperature (90C) after 15-20 kilometers. An explanation or a solution?

Hi, no problems with my 2013, heats up cabin fairly quickly, and seat warmer helps

possibly your thermostat in engine?

I think this is about normal. The engine really does take a long time to heat up compared to my other car (Hyundai Santa Fe 2.4). I think it's because it's a smallish engine with turbo, so it doesn't need to rev much to reach intended speed. Have you tried revving higher in the first few minutes (e.g. put it in sport mode)?

And I just noticed you also have the base model like mine. We don't have automatic climate so the car doesn't get to decide the optimal fan speed to heat up the car. I wonder if the others with auto climate don't have the same problem.

I notice the same thing in my B250. I recall reading somewhere that if you turn climate control off at first, it gives the engine coolant a better chance at getting warmer in less time. I gave that a try and it does work, but it only shaves a couple minutes off the time it takes to warm up. What others have said about the low revs is true. I find that normal city driving takes forever to warm up the engine because of the low revs in Eco mode. But as soon as I get on the highway, it finally gets to do the kind of work needed to warm things up quicker. One trick I have tried is to switch to manual mode and keep the revs a bit higher using lower gears until warm-up. But then you'll use more gas.
