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

When my fan is ment to be off what I seem to get is air directly from outside , I assumed that it should be closed out from outside,

Let me be the first to deflate the build date hypothesis. Yes I bought my Grenadier in September but it is a model year 2024 built in December of 2023.

That doesn’t deflate my hypothesis as I wasn’t asking for “build” dates, but “BUY” dates.

There has to be a rational reason why most of the A/C issues seem to be from the first purchased models. I own 2 myself and I have 2 friends with 1 & 2 each, so 5 in total between us, all bought after May 2024 (3 different dealers/states as well) and none of us have any A/C issues. I don’t think that’s luck. If you noticed I didn’t ask for build dates, but when purchased. That’s the secret IMO. It’s like they found the issues (whether it’s emptying out the system and recharging the ones on the lot or whatever they figured out). One of mine has a build date of 11-23, but I didn’t purchase it until May 2024. So “IMO” they figured out some of the A/C issues and fixed the ones still on the dealership lots before they were sold. So really has nothing to do with build dates at all, it’s the buy dates that’s important. Still waiting for ANYONE to post their info if purchased after May 2024 and have A/C issues.

My dealer did say they heavily tested the HVAC system as part of the PDI. Made sure it was bled fully and free of air in the system, both coolant reservoirs topped off etc. What exactly the complete testing entails I cannot say. All I know is my system works.

But for every positive there is a negative. My OEM winch would not power out from day one so that is getting replaced under warranty today. The winch was actually in stock in the US and did not have to be shipped from Europe.

I don't think any of this is rocket science. Ever since my Gren went back in a second time to have the AC vacuum filled and purged it has worked well on Auto but still gets up to its old tricks if I attempt to use a manual setting. Basically, before a certain manufacturing date it looks like a lot of the AC units that fitted were sub-par (with sticky valves or poor controls or whatever) and to compound the issue a lot of the the early production models were also badly plumbed and/or primed:

1. Bad AC unit + bad priming = Batsh1t crazy, INEOS will first instruct to have the system re-primed to eliminate this from the equation.
2. Bad AC unit + correct priming = Temperamental. You're going to have to live with it until INEOS come clean and offer a solution
3. Good AC unit + bad priming = Temperamental but should be straightforward to rectify
4. Good AC unit + good priming = Congratulations, you obviously bought a vehicle built after the date INEOS got their sh1t together
