I just bought a 2019 CR-V in June (3rd one). When I would use the auto start, the car would automatically turn on the heat or a/c on full blast to get the car to 70 degrees. Now, when I use the auto start, it just turns the car on and that's it. I don't know if I changed something or if something is wrong with the car.

Could be it's already in a moderate temperature inside:

While the engine is running, the vehicle will
automatically precondition inside the vehicle.
When it is warm outside:
• The air conditioning is activated in recirculation
mode.
When it is cold outside:
• The defroster is activated at a moderately warm
temperature.
• The rear defogger and door mirror heaters* are
activated.
• The seat and heated steering wheel are activated*

That's what I thought too, but the one day I got into my car it was like 40 degrees outside. There's no way the temp was even close to 72 degrees.

On that 40* day, was the motor cold when remote started? After remote starting, how long until you got in? Approximately.

It should still do the same, it just won't crank up the fan if it needs heat until the coolant hits a set temperature. It might have a higher set temperature on the 19s (and 17 and 18s with the updated climate control module). The biggest problem I see is a 1.5L engine is basically useless for generating heat without any load when it's cold.

As long as it's trying to heat, that might be all you can ask for.

These vehicles aren't known for having very good heaters. Or more specifically, these 1.5L engines aren't known for being able to crank out enough heat to warm up the inside of the car by idling when it is cold out.

That's not to say that you might not have some other issue going on, but lack of enough heat has been a common complaint on this message board.

Anybody with weak heater ever ask the dealership to “plug-in” from a cold start and ask the dealership for a copy of the diagnostics?

I have 2018 touring its my first car with remote start was real excited about. Tried it out last winter after running for 10 mins. got in no heat at all. had to start driving before any heat started. In my opinion its worthless on this vehicle.

Have you advised your service department?.......and what did they say?

I have the same problem - poor design. It was 45 degrees out side and I was driving fo over an hour but no heat. At best to was just slightly warm. Wonder what the defrost will do when it is cold outside. The 2019 is one issue after another. It now started to brake fo no reason.

Because of the oil dilution recall, um,update, Honda reprogrammed the ECU so that all of the heat stays in the engine to burn off the fuel that was getting in to the oil at idle and in cooler temps, instead of heating the cabin. You can leave the car in idle for 8 hours and it still won't heat up or defrost your windows. On my 2018 ex-l, the temp guage will not even register until I've driven for 5-10 mins. I'll be taking it in, again for this very problem. 12th and last Honda. .

Wow! 45* ambient, driving for an hour and no heat?.....Really?

Same here, I am going for the lemon law if they do not resolve my long list of issues with my 2019 - my last Honda.

goodluck.....they are still having issues with engine temp in cold weather

Last year, mine used to do that too but this year, I noticed that when I used the remote start it didn't immediately turn on the fan. I am not sure if this was due to a software update or if I just never used auto start when it was 40 out. I live in TX so don't have to worry about the heating side of it too much. I mainly use this now to get the oil moving and then I start driving almost immediately. I do have the oil dilution issue which the dealership says isn't bad enough to give me the repair so this is my workaround. In any event, when I found out about how long it takes to heat and my short drives, I basically don't use the Auto temp setting at all in the winter until after the car is completely warmed up.

To speed up warming up of the engine, I drive in S for a few miles w/o the heater. That has helped a lot. Once the needle moves a little, I do set the fan speed at 1 or 2 and that starts giving me a little heat but doesn't take so much off the engine that it causes an issue. I do live in TX so it's not frigid yet so fortunately, don't have to deal with that much. Once the car is at operating temperature, I can usually turn Auto on and it then works as it should.

If I set it on Auto from the start, it takes too much of the heat away and never warms up. I do not know why Honda doesn't reprogram to not set the fan speed on high until the car is at operating temperature. I've known since I was like 10 that the car takes longer to heat up if the fan is removing all the heat from the engine to try to warm the inside. Certainly, the programmers can figure out that 'if car not at operating temperature don't turn the fan on high'.

What part of the US do you live in? I've only tried the auto start a couple of times during the summer months, but 10 minutes on a 98 degree day was not enough to cool the interior to 72 degrees. It was cooler than not using the auto start. As for those who complained about the heaters not warming up quickly, I do not understand. My '18 Touring heats the cabin in a short period of time. I got in this morning (SoCal), 42 degrees outside, I never warm up my cars, just start it up and drive. Within 2 miles it was already blowing very warm air (set at 73 degrees). I lowered it to 70 degrees after mile 4.

My observance earlier this morning......18F ambient, 41F in the garage

^^^This^^^ 18F this morning. Started the V, hvac in manual mode, temp set to HI, fan at #3, let rpms drop to 1200 (maybe 30 seconds and oil has easily reached top of motor), and started driving. Drove 1.4 miles to the Post Office at <35 mph (residential), coolant temp at 137F and thermometer in the left vent reading 89F when arriving at the Post Office. Same route back home, 2.8 miles round trip, maybe <15 minutes total (?‍♂). Arriving back at the house coolant temp 163F, vent thermometer 121F, temp still set to HI.
