Power steering noise

[Eric.S.]

Hello everyone I was finally able to pick up my grenadier yesterday Unfortunately, I noticed at home that my power steering makes a strange noise. I think it's not a normal noise, or? The filling level in the container was at maximum with the engine warm but switched off. The German instructions do not say exactly in which condition the oil should be checked. Does anyone have an idea? I tried to post a video but I always see the file is too big (7mb)
Thank you

An update.

I put the truck on stands and removed the cap and tried to burp air out of the lines as some have suggested. After about 100 turns back and forth, absolutely no sign of bubbles in the reservoir and zero effect on the whine.

My dealer finally got back to me this morning with the strong stance of “They all do it and yours sounds like every single one we have on our lot.” Friendly enough to suggest I come by to verify that for myself, but with a definite commitment to not being able to help me with it. There’s simply no possible way they can all be as bad as mine and their refusal to even accept that it’s clear there’s some variance built into this obvious defect is beyond frustrating.

If you’re reading this before purchasing one of these, I would absolutely NOT buy one until it’s clear that this is sorted. It has completely ruined this insanely expensive experience for me and I wish I could go back in time and not purchase the truck.

Should just go and see whether all the trucks are the whine audible from in cabin..

That really sucks. For the sake of all of us, even the fanboys that think it’s a cute quirk, I hope you video it and put it on you tube and blow it up as much as possible.

Ineos is really fing stupid with these self inflicted damage to reputation.. I mean how much can it cost to replace these egregiously bad examples?
They are not a volume brand.. what is the point of having these shtty units out there with pissed off owners evangelizing against the brand?

There should definitely not be any noise. My diesel VIN 8xx has no squeal and the two loaners I have had for servicing/recalls (petrol 15k and diesel 1k) were quiet as well.
I hope you all can get a resolution as those video examples sound horrendous.

Here is a recording from inside the cabin.

The iPhone mic doesn’t seem to capture it digitally like how it hits the center of your brain in person, but it’s definitely there, I cannot unhear it, and I’m of the opinion that an $87,570 vehicle should not make this effing noise, especially knowing that not all of them do it.

that’s with windows up? If so… waaaaayyy too loud.. you should not find too many on the dealer lot at that level

This is with windows up and with the pump covered in a layer of sound deadening material which I forgot about. Will need to remove that and reshoot.

I don’t even drive the car anymore which may sound like an over reaction if you’re reading this and haven’t experienced it, but it’s really that bad/embarrassing. My wife told me it’s the first thing she hears before knowing I’m home. Its frequency carries through anything below driving above 15-20 mph, and with windows down it’s audible essentially anytime you turn the wheel, regardless of speed. It makes the casual dismissal of this issue that much more frustrating.

Need to stop my own whining for a bit before this takes over our holiday Will report back after I make it to the dealer. Appreciate all the feedback.

Hopefully this video works and helps in your comparison to others. The first part is windows up - no sound at all. You can then hear me put the windows down - the pump sound is present but I think much quieter than yours.

Kind of late to this thread. I hate that folks are having issues with the Power Steering Pump noises!

Fortunately we do not have any Power Steering Pump (PSP) whine or noises whatsoever. Our Grenadier was purchased off the lot back in late August of this year (2024) and has a build date of 4/24.

I have heard the PSP noises on a couple of Grenadiers I have seen and wheeled with but for some reason ours has never had an issue whether on/off road or while parked and moving the steering. We have 2500 miles on it now with about half being off road with a mix of rock crawling/washboard/snow/fire roads and haven't heard a peep out of the PSP.

Not certain why mine has no issues with the noises yet others are.

 

[Dlucky]

Pretty much, yes. Like many components on these vehicles some break-in time helped.
I recall steering pump/motor noise was a big topic when the US market launched then it seemed to calm down somewhat. Unsure if folks became desensitised or if their steering also became quieter then forgotten about.

No it’s still a terrible noise. None of the dealers here can or are willing to come up with a better solution than telling us it’s in a normal range.

 

[Zimm]

This should really be a tsb. My lx470 had one on the tcase vibration, and that was a hell of a lot less unnerving and yet much more expensive fix.

Good Morning Gents!

New Ineos owner here. Power steering squeal, although tolerable, is quite annoying when you're trying to show the car to your buddies and there's a loud, obnoxious whine on your ultra-reliable car constantly going on and trying to brush it off as a quirk. Every single Grenadier had the noise at my dealership and from what I can tell from sitting in the front for a few hours while they processed paperwork, the noise seems consistent across the 12ish different cars that were being test driven.

If it's not a component issue, and it's working "as intended", I was thinking there may be a way to dampen the sound to reduce the sound signature from the engine bay as a temporary solution. Has anyone tried this? I did add some sound deadening material to the hood under the cover and that has completely eliminated and sound entering the cabin but since the squeal seems to be a high frequency range noise, whenever you're in an area that's enclosed like a parking garage the sound is very distracting.

Since I'm new here, I was thinking that we should/could create a pinned thread with all Grenadier owners with the problem and a recording to maybe get Ineos to address the issue. Seems like it would be in their best interest to address it as it's not a good look for your "apocalypse" vehicle to be screaming at idle.

What sound deadening material did you use under the hood?

 

[DFW Guy]

I'm slowly applying Dynamat Xtreme sound deadening material. Although the whole DB reduction debate rages on in the sound deadening communities, I think it's due to people fundamentally misunderstanding what the material does at each level. Hopefully when I'm finished with the engine bay, a lot of those reverbing squeaks and whines will be reduced. I also noticed that my steering pump fluid was on the low side after letting the vehicle cool so running to grab that fluid right now.

The stuff I'm applying is really only for flat metal surfaces where vibrations can make sound. So all it does is turn your high frequency whine into a low frequency hum. It may still be as "loud" but the frequency is what really annoys people. Difference between the sexy V8 growl and a 4-cylinder ecotech whine. I've also applied it sparingly under the front floor mats and rear passenger floor mats. I still need to do the area under the seats but I've been too busy at the office to get around to it.

I’m in. Mine squeals like a dentist drill hooked up to an amplifier. It’s definitely ridiculous in indoor parking lots..

I would think most of the noise from the electric steering pump is being directed forward toward the front grill area and down at the pavement making it more noticeable from the front of the vehicle. I had the same noise for a couple of days after I first brought the vehicle home and was standing in front of it. For sure, there is still a very slight hydraulic pump whining noise but nothing I can detect from inside the vehicle and nowhere near like the sounds others are describing. It’s amazing the variability in noise this issue is causing across the different build dates.

In fact, the loudest thing in the engine compartment is the high pressure fuel pump clicking/tapping away on the back end of the cylinder head near the firewall. You can hear it just walking up to the vehicle especially on the right hand side when at cold idle. It clatters enough to make you think the engine only has minutes to live but some high pressure direct injection systems are just noisy. Also some brands do a better job of isolating the sounds better than others.

 

[DFW Guy]

I'm thinking this may be a DIY solution. I know they make treated heat-resistant fire proof sound dampening material with some metal adjustable clamps. If I can isolate the sound well enough to at least be quieter than the engine idle when the bay is shut, I will be happy. I've seen the proof of concept with the Rolls-Royce engine bay where basically everything is covered with hard plastic with a carpet underlay to basically remove all noise.

I just picked mine up on the 30th, but on the 28th when I was waiting on the wife to help decide the final color (I was torn between a Mushroom and Grey) pretty much every Grenadier that was being test driven (12+) all made the whining noise. So it may be a batch issue/calibration setting done at the factory. It's definitely coming from the actual pump itself and not an attached component. I just hand covered it with some interior deadening material and it reduced the sound signature significantly.

Hopefully it's not a genuinely faulty pump and it's just a tractor part they sourced from wherever where pump noise would be a concern.

I found my personal cars whine is much more pronounced than the loaner I had for a month. Although obnoxious, and always fun to explain to people what it is, I never found it a deal breaker. I do think that they could of sourced a quieter pump. I feel like its part of the rushed engineering portions of this car. Overall, I have gotten used to it and barely notice it unless I am driving with windows down in an enclosed and tight car park.
