Always a fun game 🙂
So, short version: I’m driving our Ignis (all-wheel drive version) along a dual carriageway at a steady 70mph (on cruise control). There is a sudden jolt, sort of like hitting a puddle at speed. The car keeps on going though. In fact it’s driving just fine, but now there is much more pronounced “road noise”. The sort of sound you’d get with badly worn tyres, but they don’t just suddenly go like that. Any ideas?
Some supplementary information: The tyres are brand new (only a few hundred miles). The gearbox is also brand new. In fact I was driving it back from the garage (250 miles away) who had just fitted a new gearbox (under warranty) after the previous one failed. Obviously taking it back to that garage is out. I’ll take it to our local dealer later today, but just confused as to what could suddenly go and leave a car that makes a loud “humming” noise?
Wheel bearing?
Drive shaft seems the obvious…fairly confident they’d have to remove the drive shifts to fit a new gearbox. They’ve probably ballsed up the re fit.
Fuel pump glitching and now noisy?
The gangle pin has dropped out of the dosset overrider. Expect they mistakenly fitted an anti-clockwise one when they put it back together.
Now where would you come up with the name 'Gangle pin' 😆
Loose or missing or sheared wheel nuts ?
I had a similar thing a few years ago in a Mondeo. A front coil spring had snapped. In my case the sharp end tore through the tyre, which was fun alongside a truck on the M6.
Wheel bearing wouldn’t suddenly go like that would it? I’d expect the noise just to get progressively worse. But this was fine for 200 miles then “bang”.
Wheel nuts would make for funny handling I’d have though, but it drives just fine. It’s just noisy.
Drive shafts were my first though, but don’t they usually lead to a judder or something rather than just “road noise”.
I’m sure this is going to get complicated as I can’t take it all the way back to the garage that fitted the gearbox and the warranty has just expired 🙁
My suggestion would be a borked 'box install or something was already duff and the 'box replacement has disturbed it.
Or of course the gangle pin.
Do you have the facilities to get it off the ground or another way to check if the drive to the rear is still ok? Could well be the rear shaft has done something funny and lost drive. That would still make the car driveable but with some extra noise.
a noisy bearing can sound exactly like road noise. perhaps the jolt was the bearing face collapsing, or you did hit something and the extra force on the bearing was the thing that took it over the edge
Can’t think of any way to check the AWD system, but that would make sense.
A bearing collapse could make sense too and it is that type of noise.
I’ll check the gangle pin though. I think the AWD version needs a purple one.
I read the title and your username and thought I had the answer, but sadly not.
If it's related to the recent fix, and chances are it is, then you should have no issue getting remedial work done without charge. The only problem with that is the 250 mile away garage would be the ones to do it as it was their issue to solve.
Could it be something has dropped into a rotating part, like a socket or stone in behind the dust sheild on the discs?
Transfer box bearing collapsed
Mid drive shaft bearing collapse
Rear diff bearing failure
You need to isolate if its engine or mechanical, does it still rumble with the engine on, in neutral, rolling down a gradient. Probably is going to be the answer.
Was it a reputable garage who fitted it. Had the old box been jetwashed and some 100w oil wanged in and its been given back to you. Every chance they have bodged something inside the box and its let go as the thing that caused the thing to fail in the first place hasn't been fixed and the bodgerama has now also failed. Or they forgot the gearbox oil.
Yes I expect it’s going to get messy. Moral of the story is not to break down a long way from home 🙂 Recovery doesn’t seem to be a thing anymore so we were stuck with getting it fixed down there. Oh well, worse things happen at sea apparently.
I did have a Rover 214 once. Pig would have been generous 🙂
Sticking it in neutral makes no difference to the sound by the way.
almost certainly something the garage did wrong - not bolt the prop shaft on properly after changing the gearbox. get underneath and see if the bolts all looktight on the flanges and so on, and are the gearbox mounts tight etc. if the prop falls off at the front when you are driving it could be catastrophic
Gearbox was replaced by Suzuki dealer with a brand new one under warranty. To make things more fun it failed right at the end of the warranty which had just expired. I’d have no issue if I could take it back to that dealer but that’s not really practical (and it may not be safe to drive it that far)
It’s mentioned above , but have you checked your wheel nuts are tight ?
I had a similar thing in my old T5 after the tyres had been changed the week before.
Started off with a quiet rumble that I ignored for a few miles then just got very loud. Nothing was obvious and the bolts were not hanging out or anything I was a bit stumped.
I got my wheel brace out and checked the nuts and they were loose on passenger front side.
Jacked up that side and tightened nuts, could feel the wheel straighten itself back onto the axle.
Didn’t have a problem after that , and now check the bolts a day or so after having wheels off ( which apparently you should do anyway 😉)
I've had a wheel bearing collapse with a bang noise before. Was on a motorbike though.
Kia and a few others ask you to change all 4 tyres at once. Pairing new with old wrecks the 4WD system somehow. Maybe Ignis is similar? I've made the massive assumption there that you only changed frons/rears rather than all four tyres.
Diff wind up due to different diameter on new V old tyres. The feww mm means the diffs have to constantly work and this can lead to increase wear.
Dont think it will be wheel nuts, ime tjey knock when loose and work themselves free and your wheels fall off
Its something the garage has either over or under tightened and its failed or fallen off
Still could be something inside the new gearbox though, or diff plantery gear.
I wonder if something has dropped in the diff or transfer box when the driveshaft were removed to facilitate the gearbox change
All four tyres were replaced at once.
Undershield, inner arch trim not refitted properly and droped off allowing more road noise to get in?
Some supplementary information
who had just fitted a new gearbox
I think its a bit more than supplementary information! New gearbox fitted and now an issue with the drivetrain!!!!!! Park it up ring the garage to flatbed it back and sort you out with a curtesy car.
Spring is a good shout. If a spring breaks it can lower the car on one side and upset the geometry. This might then make the camber wrong, so the tyre would then be riding on its edge which would account for more tyre noise.
Springs do break, in fact bits of spring are one of the most common car parts I see on the road when cycling. I have had two fail, both on the rear of the Passat. One went, with a SPANG, I assumed I'd hit something - then the other side also spanged some time later. When walking up to the car I did notice that the wheel arches looked low, but I stupidly never put 2, 2 and 2 together. It then developed a noise that sounded like a bad wheel bearing, because the inside edge of the rear tyres became sawtoothed. It passed an MOT then failed the next one on broken springs!
In my case I didn't immediately get tyre noise but it's entirely possible that you would, and it could also break or fold up without a noise. Maybe park on flat ground and compare the gap between wheel arch and tyre on each side. See how many fingers you can get in each side.
Love a guessing game.
Possibly a mount has failed or is loose and part of the drivetrain is touching the shell. Really doesn't take much and the noise is really quite loud.

If the part was replaced under warranty and now fails, or there was an issue with the workmanship, just because the warranty has now failed doesn't mean you don't have any recourse. If it's a manufacturer warranty (i.e. a Suzuki one) it's with Suzuki, not the dealer.
The fitting dealer was still obliged to repair properly, and if they didn't, it's the original warranty claim, rather than anything new (subject to what the actual warranty says).
You also have your statutory rights which would be unaffected by the warranty. Take it to your nearest competent dealer, get them to inspect - if it relates to the warranty work, get on to the other garage and Suzuki.
Yes, if something's gone wrong immediately as a result of the work they did, then they'll have to fix it. Many garages warranty their work for longer, but it should be rectified if it happened on the way home!
OK, just got back from my local friendly Suzuki dealer and apparently somebody forgot to replace the oil in the transfer box, which is now toast 🙁
Now to phone the people who fitted the gearbox to see what they say.

See what they say? If they say anything other than 'OMG we're so sorry a truck is going to pick up your car in the next few hours, Enterprise will be calling you in the next few minutes to arrange your choice of hire car, please accept our most sincere apologies' I'd be hitting the roof.
PS I think my diagnostic post was the longest and wrongest, do I win something?
Now to phone the people who fitted the gearbox to see what they say.
Assuming they're a franchised dealer, if they say anything other than "yes, of course we will pay for the repairs at your local dealer, as well as the cost of a courtesy car while you wait" then get straight on to Suzuki and make a fuss.
Indeed, having said that I would ask your dealer to call them and explain - less likely to be given the run around then.
And by them I mean the garage that fitted it.
Sorry for multiple posts!
Damn! beaten by 17 mins. Was just on my way to posting that it might be lack of oil in the transfer box 😉
I'd go with dealer it's with now sorting out something with dealer who made the mistake. Takes you out the conversation and they can argue out with Suzuki between them if they need to.
That's a rather big cock up !
Nice try Jordon 🙂
Just had a call from my local dealer. Although they did originally recommend that I phone the dealer who fitted the gearbox they actually called them after I left and have sorted it all out. So, apparently it will be fixed under warranty. Not sure how long that will take but I'm pretty happy with the service so far.
Excellent news!
That's as good a result as could be hoped for in the circumstances

someone has a meeting without biscuits on monday morning....
I'm kinda surprised that they'd need to drain the transfer box in the first place.
Off of the early 90's I was round a mate's house playing Megadrive when his Mum came home in a bit of a huff. She'd been driving her Ford Escort back from the local dealer after a service when it broke down. Turns out they hadn't put any oil back in the engine after draining it.
Or they forgot the gearbox oil.
Close , but no prize. I wouldnt have thought they would have to drain the transfer case. Must be a Suzuki thing .
I know a chap who had a Rover 414 , whihc rather than no oil , got 2 lots as the apprentice, then the lead mechanic both both added 4 1/2 ltrs. blew the core plugs out the block on the way home.
