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

Our AC is working well but I think there is a BIAS to the rear vents. For example, we have front or front and feet....The rear vents blow incredibly but the fronts, on either setting, takes a bit.....

I had this symptom + when floor vents where open I got warm air from the dash vents. Issue was low refrigerant. Once topped up my ac has been perfect. Dealer found it right away.

Agree very random.

1 week in an mine seems to be working fine

Seasonal temps are beautiful right now. Generally no AC required, with occasional heat. Which brings us back to the mindless, crazy HVAC system and blowing 30 seconds of cold air even when the engine is up to temp.

 

[euroflo]

mine has been on auto for the last 4500Ks...working ok.. then all of a sudden hot air from the rear vents...
tried it the next day and all working fine again....
must be a full stop or something in the code that's in the wrong place and accumulates over time and triggers....
I reckon it forgets what position the hot water valve is in.....
So even if you did manage to get it to a service centre and for them to see the fault... they still wouldn't know what the cause was...
Hopefully one eagle eyed programmer will pick it up and resolve the issue once and for all......

Mine can do very hot or very cold very well. So in middle of summer or middle of winter it is superb.

Anything in between full hot or full cold is a bit hit and miss. The auto function is weird and doesn’t work well at all so I use manual control. It’s slow to respond to changes in temp demand but gets there eventually.

On the plus side the heated seats are ferocious. Lovely in winter.

And in summer I usually have the windows open. Where I live rarely gets much above 25C though so it’s not that much of an issue.

The shortcomings are nowhere near a deal breaker for me but they are not befitting an £80k vehicle.

Naive question...but I read often that the problems occurs suddenly...

...is it simply possible that the heat exchanger is iced? And the next morning it is defrosted?

This could indeed be one of the causes.
(I also have issues at startup with no possible iced exchanger)

Actually it is almost impossible to exchange directly with IA.
They want you to go through the dealer who have a very limited time to test while I spent hundreds of hours in my IG.

With a direct exchange I could provide more data regarding what/when/...

This is a critical point for managing beta programs or getting feedback on prototypes: getting as many details as possible directly from users, without intermediaries.

At least, after 17 months I got this email from my dealer:

"Random aircon problem: the blower or mixer flap doesn't do what it's supposed to. The engineers are working on the problem for the moment, but unfortunately no solution has been found. IA will let you know more by e-mail."

Maybe I am just extremely lucky, but when I found this thread and just read all these posts, I was surprised to be honest because I own two Grenadiers and both have never had any A/C or heater issues. I live in Louisiana and it’s hot & humid almost thru Christmas so really only use the A/C, and I LOVE me some cold air trust me on that! The A/C’s are ran constantly when I am using either vehicle (I have also sat stationary several times from 15minutes to over an hour). Yet I can’t even run either A/C’s past the #2 fan speed (a/c on, manual, face only, recirculating are the usual settings) or I will be an iceberg. Usually it’s on fan speed #1 and it’s plenty cold. Sorry to hear of everyone else’s issues. I have only had them for 6 months and they are MY24, so maybe they fixed the issues for these? I also have a couple of friends who now own these and they also live in the south and have the same experiences as me. Hopefully none of us get the A/C

When it works it works great... Otherwise (as for all the others problems / glitch / bugs / ... ) it is hard:
- to have IA admit that something is wrong,
- even harder to have it fixed,
- especially bc it is random

Well put, when it works it works great. I’ve had my truck almost a year now and 95% of the time the AC works great but it’s that 5% that goes bad at the worst possible time. I went 3 month after purchase with no problem but since then it has gone bad maybe 30 times or more. It usually is fine if I turn it off for 10 minutes but there have been a few times where it took over 24hours before it would reset to normal. I think it’s a software issue and am hoping it gets figured for some future software update.

Wow, that’s a lot! I feel for ya. Has your dealership been any helpful? What are they saying? I’ve had mine for 6 months now and hoping I don’t have these issues down the road!!

88 degrees in Houston and Ice cold air-conditioning.

The dealer has been great but told me that even if they know what the problem is they won’t fix it unless they witness the issue happen in person. I took it in after a failure of the HVAC that lasted 24 hours. While I was driving it to the dealer the HVAC worked perfectly. I knew they would keep it a few days and hand it back saying “no problem found” and that is exactly what happened. Because it’s so intermittent the chance of them seeing the problem is slim unless they drive the vehicle daily like I do. The fortunate thing is that it’s a global issue and not just a few cars. Hopefully they can track down the problem soon. The skeptic in me says they will wait a few years when vehicles start going off warranty and then say they found a fix and then I’ll be stuck with the bill. I’m really surprised IA hasn’t said anything about it or acknowledged it since it’s so widespread.

I may be way off (anyone please correct me if i am wrong) but I thought that only the MY23/23.5 had these issues and all US models (looks like you are in California) were MY24 versions and many of the previous issues had been fixed. I own 2 Grenadiers and have a buddy in Florida and another in New York that also own one and none of us have had these issues. Do you know if you may have bought a MY23/23.5 model by chance? Just curious. We are hoping we never encounter this problem.

Since mine is almost a year old I’m guessing mine is a MY23? I personally know 5 other owners who previously were in the same Land Rover club I was in and 4 out of the 5 have the issue and one is for sure a MY24 as he just took delivery 2 months ago and he has the same problem. If you look around the forums or facebook groups you start seeing many others with the same HVAC issue. My dealer initially said it was just a leaking hose which they replaced, then said it was low on ac coolant which they topped off all to no avail. My guess is that IA knows what the issue is but because it’s so widespread it will cost them millions to address and they are dragging their heels until warranties are up.

 

[Tom109]

USA only got MY24, so we all have the same system. Your AC will be ice cold, until it isn't. It's typically short-lived, but not a pleasant Summer experience.

 

[Dual Grenny Guy]

From reading the last couple of posts seems like all USA owners will be having some type of A/C issue eventually and that Ineos is not an honorable company. Not trying to put words in anyone’s mouth, it’s just what I am reading. My buddy in Florida has had his almost a year now with well with over 20k miles, and I have been in/out of mine almost daily as well as sat running the A/C for long periods of time and again none of us any issues. I’m trying to be optimistic about my vehicles and the company who makes them, and maybe only time will tell, but I have to ask with such negative experiences why not sell it and get a vehicle with not so many issues especially if you really believe they know about an issue and are waiting for warranties to run out so they don’t have to repair it? Just me, but if I really felt this way no way I am staying with that company no matter what (even if I had to sell it at a loss). If they are doing that with the A/C, what about future issues with any other parts/systems. I obviously don’t feel this way and I hope I never do.

95% of the time it does work just fine. It’s still terribly annoying when it happens but it’s still a better vehicle than any Land Rover I have owned and I’ve owned several. It’s better than my Jeep Rubicon as far as handling and comfort go. I love driving it and look forward to long road trips with it. I’m hopeful that IA will get it together and come out with a fix soon. Maybe I should get rid of it but there is no other vehicle I would want. I use and abuse my grenadier and it just keeps going. I want a vehicle with front and rear lockers and solid axles. Aside from Ineos Jeep is the only other real option. I’ll stick with Ineos and hope they get a fix soon.
