Steering and Poor Stability

[bodhizaffa]

Improperly balanced tires have little to no impact on low speed steering feel.

Multiple issues going on w/ mine.

The loaner tires had the exact same PSI as my car.... cold at 38. The dealer replaced all of my wheels/tires from a loaner and guess what?!?!? - the car finally drives straight. As an aside, the problem wheels had weights slathered all over them. The new set has very minimal weighting. The continued commentary that some of these cars are handling very poorly simply because of improper tire pressure is a bit off base to those who have experienced significant pulling etc.

Many thanks for this info - have exactly the same issue with mine so will ask the dealer to swap rims and see what happens!

Well that’s a good result

Ok so I finally took in the IG for an alignment with 3k miles on the clock. Since I took delivery I felt that the vehicle pulled a little left and needed an alignment, but I just haven’t had time to get to it and a couple of the shops I called didn’t even want to attempt to do it as it was not in the “system”. I finally found a local show that was willing to do it as I had the alignment specs. The alignment needed a number of adjustments, but enough to also require the steering wheel to be re-centered. As part fo that process we noticed that the call joins, ALL OF THEM had some slop and a popping noise. Attached is a video that I took moving the steering wheel and you can see the “popping” at the wheel its rocked back and forth. This same exact thing was present on each one of the ball joints. My guess is that INEOS likely got a bad batch of ball joints and this is potentially leading to some of the VERY poor steering some of us have experienced. I am planning to send the video to the dealer and see what they have to say.

I drive bridgestones, 18.000 km now, and I feel fine with it, even up to 165 km/hs. Mine was produced in Jan.2023, delivered in June 2023. I drive the tires with 3.0 bar. Okay, I take two hands, I like that. No problems.

My shops say they cannot align my wheels because they do not have the correct computer program. What are they talking about ?

Not the correct computer program, but probably don't have the specs in their version of software. The alignment software is only updated so often, and many times shops will only do this update every time a frequent vehicle they align gets an actual chassis change.

The alignment specs are in the owners manual, you can show it to them and they can align it off of that

Old school aligner, drove the Grenadier up the road and then adjusted Castor and toe in, also centred the steering wheel.
No more 'floaty' feel and constant correcting.Also ESC/TSA not available,Uphill/Downhill assist not available,Braking may be compromised, warnings no longer appear.
Coincidence?

Good sharing @eddyoz.
Did old mate tell you what adjustments he made to the castor and toe?

Coincidence? Possibly not, but that suggests the steering wheel position sensor is a factor in those errors.
Funny you mention them. I had software xxx2940 update done at the end of July. Had all of those errors on the day I collected it from the agent then rock solid until Monday this week. Had them all day Monday and yesterday. Stop driving, shut down, cleared, resume, errors come back. Today (Thurs) all good. I mean, what the almighty....

Tell-tale panel:
Overall Warning light ON (which kills cruise control)
ABS warning light ON
ESC warning light ON

HMI (main screen) cycles through:
ESC not available
TSA not available
Reduced braking performance
Downhill assist not available
Uphill assist not available.

Plus for good measure I was getting an occasional power steering error on the HMI with a corresponding twitch in the steering while driving. That felt a lot like interruption of electrical power to the PS pump motor and loss of pressure.

I checked the steering angle via the off-road page on a straight section of road today. It's showing 0 degrees and my steering wheel spokes are level so I don't think I have a centering problem, but I can't discount it completely.

Adjustment , Toe In was from 6mm to 2mm and Castor LH 3+ RH 2.8+.Improved steering and still no errors coming up!

Cheers for that.

I hate to be a broken record, but my local St. Louis wheel and tire stores will not re-align my wheels until they officially receive a software upgrade. It is a very minor issue in light of the problems I have been reading about. But having my closest service shop either in Chicago or Atlanta is becoming annoying. However the vehicle is solid and a great purchase. Kujo

Can you find a full service independent mechanic shop specializing in 4x4 to do this service? Dealers are 2.5 hrs (yet to open) up to 5.5 hrs from me. My "local" non-warranty items mechanic is 1 hr away. Fully capable of doing an alignment.

Holman Motorcars in St. Louis quoted me a price of $ 650.00 to align my wheels. Other shops refuse because they are afraid that the software programs on the car might be affected, and they have no idea what to then do.

Have you tried any reputable off road shops in your area? $650 for an alignment is flat out highway robbery

Edit: a quick Googling shows Axleboy Offroad in O'Fallon has good reviews

Not sure what the state of play is in NA but in Australia IA have been very clear that agents (dealers) will provide extracts of the workshop manual to repairers and owners if required. I want to think a good shop (that wants your work) could contact a dealer and request the alignment procedure and specs.

What does this statement even mean? Did you ask them?

Basically, after wheel alignment. Steering angle sensor is usually required to reset to stop warning lights appearing on the dash. Steering angle, ADAS, ABS sensor are all interlinked. Most cars require diagnostic equipment to reset. Some cars are self calibrating. However, if it’s a tiny adjustment, sometimes you can get away with it.

What Skydance said. Much more precision than I was able to muster.

Thanks - I was not even aware of this!
