Let's get some perspective: Is your Grenadier AC working as it should?

[G-Man]

Who else's AC is batsh1t crazy and randomly blows hot air one day and cold the next on the exact same setting? I don't think the AC system got the attention it deserved during the 1.2 million miles of road testing, that's for sure. I love my new truck but it's the one thing that drives me nuts on pretty much a daily basis as I fiddle away at the controls and I'm surprised Ineos haven't found a fix for it yet. I gather it's down to sticky solenoid valves or such like and is probably an expensive warranty concern for them.

It would be useful to set up a poll on this forum and get an idea of what percentage and numbers of owners here have flaky AC. This forum must represent a decent amount of the Grenadier owner population, perhaps it would help sharpen Ineos' perspective on the issue if it popped up on every Google search relating to Grenadier AC issues. I don't have the ability to raise a forum poll but maybe @Stu_Barnes would consider it a worthy exercise

Am I correct in suggesting the HVAC issues seem to be mostly in NA? Just an observation.

Mine was decent, but not fantastic in keeping up with the Florida heat. Then it stopped cooling properly right when it needed the 1st oil change. Crown is St. Pete (fantastic service, BTW) found that it didn't have the proper charge on the system and corrected it. Since then, it has been fantastic.

If I were you, I would just run to the BMW showroom and pick some up for like $30. They have it in their service area and it will make sure you get the genuine product.

I also have a 4/2024 build date. The dealer took possession of it in June but I took delivery in July because I was working on selling another vehicle. I have had issues with my HVAC, not as persistent as others, but the system is inconsistent.

I checked both coolant tanks Saturday after it sat overnight (so it was well cooled down) and both tanks are below the “MIN” levels. I’m going to order some coolant along with brake fluid power steering fluid because they are all below the “MAX” lines.

It’s at least an hour each way drive. FCP Euro has all the fluids I need.

Funny enough, I just saw that yesterday and realized that's what that was too.
But, the heating/cooling is not at all consistent as others have stated.

Well, this is a new one for the HVAC / Climate Control system. On the way to taking little one to school this morning, got in after dropping her off, started the Gren, no fans, no seat heaters, and no response from any buttons, knobs, etc. I did get the following messages. Reset the system. No errors, but persistent yellow triangle on dash. Everything seems to be working again, but no idea what the warning is for.

System worked fine on the 2 mile drive there. It decided it had enough. Lol.

My AC blows cold and the heat blows hot, except when it doesn’t.

Heat- just don’t change the vent configuration or you’ll get a frosty ambient blast!

I’ve had the AC drop out - luke-warm air from front vents and fire-hot out the rear events. No procedure works to reset it. Eventually it will come back after a restart, but stopping/restarting when you need the AC does not consistently resolve the issue. Sometimes you just have to sweat and be patient.

Yes, the AC is not fit for purpose. Ineos Fail.

I've found on my Grenadier that when this happens if I flip to auto it seems to solve the issue but then in auto it keeps the fans on full blast, very odd cause I had this happen many times on a 2600 mile road trip and just couldn't stop everytime it did this to turn the car off and on.

With all the cold temps recently, has anyone experienced anything like this... On a road trip, heat is on (not using auto) but randomly you get a burst of cold air from outside the vehicle? Like the vent door shifted without you doing anything to cause it?

It’s on full blast even without the temp dial all the way to max hot? On mine, if it’s max hot and auto, fan is always blowing max, including blowing cold air while engine is cold. It’s such stupid software.

If I have temp dial even one click away from max hot, auto fan speed appears to work more expected. When engine is cold it may only blast air for 2-3 seconds, then stop blowing until engine warms up
