My RR Supercharged heating takes an age to warm up the car - miles further than any other car I have or have had - If its frosty outside, with everything set to auto and the temp set to 70, it blows lukewarm air at top fan speed for ages to little effect - v. noisy and annoying. I've moaned to the dealer who just keep saying it's performing to manufacturer specification. It's up for renewal in a few months and despite loving the car this is the one thing that could kill it for me - a long winter of having to freeze for the first 15 minutes of a journey listening to a fan will make me mad.

Has anyone else had this problem?

By running the fan on full it will take longer to get warm. Try turning the fan down and see if that helps.

I'm in the US, only the Corvette C5 Z06, Bike and wife's Multipla are in the UK for summer hols. That's why the heater is a problem - it can be -15C many mornings over here - heated wheel and seat help, but being blasted with lukewarm air does not....

Leave it on auto climate control, electric seats and steering wheel on and it will only blow out warm air when it is hot enough. You are expecting miracles if you expect a stone cold lump of steel with a few gallons of cold oil and coolant to heat up instantly, when the night time temp drops to -15c. It's basic physics!

Get the cold winter pack fitted (if it is not a factory only fit) and plug in your car at night so it will be warm in the morning.

Are you using the defrost button? (turns everything on full and the heated windows)

If not you should be! works a charm on ours.

I'm only moaning because every other car I have is warm as toast within a mile or two or five minutes whichever comes first so there really is no excuse - either poor design or faulty sensors that the service people cannot be bothered to find and fix.... The main issue with all of this is that I have to put it in the garage and leave the wife's car outside!

Remember a Range Rover is a lot of cabin air to heat. Also all that leather is very cold and will make the interior take longer to heat up.

I am not trying to defend LR here, but unless you have a faulty heater maybe you are expecting a little too much if your last car had a smaller interior. Also remember the cabin or a RR is a lot higher than even a large car so it will obviously take a lot longer for the hot air (at top) to replace the cold air (lower down, where you sit) The height of the cabin can be a major factor.

There's something wrong with your car or your settings. My heater begins giving out warm air within a few hundred yards of a cold start.
Hassle the dealer.

At last! The dealer agrees it does not work properly and APOLOGISED. I made them start my car next to another RR from cold (it's minus 10C here today) and mine blew out lukewarm air for ages while the other one got warm.... So after 24 months of a 30 month lease it's good for the dealer to accept something. Interestingly no fault codes show up and that's why they kept telling me 'operating to manufacturers specification'.

They now tell me it'll be a long labour-intensive exercise to find where the fault is, so I have a loaner LR2 to look at (no way I am driving it).
