Gearbox 3500 miles in - Gear 2, 4 and 6 got stiffer..

So I managed to re-produce the loud banging inside the car, definitely comes from front passenger side and somewhere underneath the car. Basically it only occurs under acceleration or braking when the road surface is uneven.

I have also noticed quite significant whistling noise, almost like a whine from the engine compartment. It happens in Neutral as well as while driving and mainly noticeable between 1400 and 2200 revs.

I made a video but for some reason the sound is very muted, it's much louder in person however turning up your speakers should help:



I have not reported these things back to the dealer yet, will do on Thursday/Friday however at this point I cannot be bothered taking it back, I ll wait for Hyundai Finance to get back to me in regards to the Rejection. This is definitely what I'd call a Friday Afternoon car, both from a manufacturing standpoint and from the service I have received.

Sad to hear that. You thought about a Kia Stinger? Maybe even a GT? RWD/AWD and quite a nice car for the price ;)

I want nothing to do with Korean cars after this circus mate, it will be Jap or German for me again and definitely not brand new, because it seems that new cars are just built poorly across all brands.

My neighbour down the road has a 2018 BMW X5M and is currently in talks with the dealer to get a replacement one since his panoramic roof is leaking badly, causing his very expensive individual option leather to get soaked every time it rains. Apparently they cannot find a fault with it as all drainage is clear of debris and the rubber seals themselves seem fine. So yeah, even those £90k new cars have problems, I fully understand it is not a specific brand issue.

I am thinking late 2011/2012 E92 M3 Competition, 2014-2015 Cayman S or something else of that nature. So many possibilities at around £30k these days when looking at used cars.
 
That sound is similar to what lorries make. Definitely something weird...

At first I thought it was transmission noise, because it's normal to have a tiny bit of whine from it at low revolutions, however since it does it in neutral it's not. You can actually hear the transmission noise when it starts driving slowly and then this whine comes on top of that.

While I won't bother taking the car in, I am very tempted to go into the dealership later this week and make an absolute mess of a scene in front of other potential customers lol. Probably won't help things but it would certainly make me feel better after the useless service I have received lol.

Are you certain the loud bang isn't axle tramp?

Mine will do it under hard acceleration on a damp road in cold temps with the P Zero's fitted, any small bump in the surface will make it worse, as the tyres slip and grip suddenly and causes the suspension to hit the bump stops with a bang that sounds like something has broken. The other cause can be the engine moving hard on it's mounts too which is why some change the engine mount material.

Older rear wheel drive cars axle tramp would feel and sound like your axle was hitting the floor pan so it's nothing new but needs very expensive suspension engineering to remove in a FWD car. Renault with the RS Megane 250/265/270 and Ford with the Mk2 Focus RS came up with near identical special front hubs to solve it and had a tasty legal battle over who came up with it first.

It's not done it with my winter tyres fitted though as the compound still works fully at lower temps while the P Zero struggles. My diff doesn't clunk on full lock when turning off my drive with the winters either which the P Zero's do. Talking to a buddy who works in motorsport he said the clunking is down to the LSD pushing the tyre across the surface as the tyre is out of it's working temp range.

Yeah I am fairly certain, I know the bang it makes when it axle tramps which has happened once or twice (I don't usually floor it in first gear tbh) but this is different, it actually feels like a component bounced and went back into place. It's hard to explain, perhaps i will try to capture it on video but due to the nature of it, re-producing it will take some effort.

I don't know what else it could be, since going through potholes normally is fine, no noises. All I know is, it did not do this before the gearbox work. What components are disconnected from the car for them to take the box out that could be making such noise?

Actually, that's the worst thing you could possibly do, especially if your expecting Hyundai to accept the car back. You're welcome to do what you choose but I'd advise against it. You just have to ask yourself; if I do so, will it actually service a good purpose. Honestly, it's going to cause you more difficulties.

I also got mad once, a very long time ago thinking my personal kerfuffle would alert other owners or prospective owners. Did nothing but make me the arse and the one with a chip on my shoulder. Otherwise, the intentions were crap and it didn't accomplish anything. Didn't make me feel any better either. Just reminded me of how stupid it was.

The components that must be removed for access to the transmission removal are; the entire front end, undercarriage and engine and all attached components.. If they didn't align the clutch properly on reassembly, you'll get this type of noise. The bump or bang is very possibly one of the heat shields on the exhaust.

However, when you remove the engine and transmission, there's always a possibility or clearance issue with heat shields and other engine items that were remove to gain access to the transmission. IE., fuel line attachments, hoses, emission components etc. making contact with the chassis. There are a plethora of lines and electrical connections that need to be secured properly with assorted OEM zip ties and clamps.

Personally, I believe your dealership service is near incompetent and lacking. When the tech drove the car, the tech didn't want to analyze the whine or the bump. Just like with the transmission gear engagement and clutch cables issues you experienced. They're not doing the diligence required. Get it in, get it out as fast as possible, don't worry about the QC'ing of the worked performed.

I'll also, second the axle tramp or wheel hop that's already been suggested; if an underbody suspension components were not installed correctly and properly torqued.

Turbo whine is most likely a piece of foreign debris that has dislodged in side the turbo housing or a bent blade. Most times service departments don't take the time to cap off or block vital parts like the Turbo inlets, oil & transmission line etc. They just let them dangle and stay open to debris contamination. Yes it's BS and causes additional problems later on during reassembly and for the owner. They generally don't take the do care necessary to protect the subsystem components.

If it were mine, I'd take it back to another dealership, other than the one it came from or is now being utilized. Such bad service and mechanical incompetence, is truly alarming.

I ran into this with a Nissan Dealership once and it was a nightmare of mistakes, damage, and inconvenience.

Sorry about all the issues and I wish you all the best in whatever you decide.

MERRY CHRISTMAS!

Nah I won't be doing it, I know it won't do the situation any good no matter how tempting it is.

As for the gearbox, I don't think the engine has to come out does it? At least it didn't for my Type R when I had gearbox upgrades installed.

Regardless, your suggestion about another dealer is sadly not applicable here. All the work that's ever been done to this car is from this dealer and since they are the supplier of the vehicle, I have to stick with them if I want a good case for my Rejection. The more they fail, the easier it is for me to get all my money back, which is ultimately the outcome I am after :)

I am going to call them on Friday morning to report the issues, however I am not sure if I should take the car in again or just mention the issues but refuse to let them "fix it" anymore, since they just break it further and I am left without a car for a longer period.


Merry Christmas to you too!

Hello, in the end about my problem 1,2,3 and R there will be no news at the end until Thursday, he told me that I had to try it and then give the incidence, so we will see where the thing will go, I noticed a change was put harder those marches and sometimes it costs to enter you have to treat it aggressively and it is not comfortable. Another question the car I bought in April and I saw many from here that you returned the car but can only the first month not? And without modifications I suppose since mine you have other escape tails .. Merry Christmas!
 
Hello, today I take the car to the hyundai, the head of the workshop taller the car to test it and indeed he told me exactly the problem, marches traveled hard even noticing gears while the car was running, while standing still is perfect. What to expect to be called for the news.
 
If you get an E9X M3 make sure the rod bearings have been replaced, a mate of mine had one written off because his engine went pop and a replacement is £20k. I’d go Cayman, my plan has always been to keep the Hyundai until I’ve done what I want to my house and pick up a low mileage GT4. I’ll probably end up moving again and it’ll screw my plans.

Yeah late comp pack have revised bearings but still can go, rod bearings and actuators would be things I'd look to be changed or budget for if they have not.
 
I've been trying to narrow down that whining/whistle noise and I am almost fairly certain it is not the turbo but perhaps a pulley of some sort. The sound is too distinctive to be a turbo and only audible between 1200 and 3000 RPM, after that all sorts of other sounds muffle it (engine, exhaust, turbo).

On another note, went for a blast down Surrey Hills yesterday morning with a few other hot hatches. On the way back I ran out of washer fluid so popped the bonnet to put some in and guess what I saw:

Yep, my undertray is missing.. Looks like the Hyundai Master technician was doing this job on a Friday as well :)

Going to the dealership to make a mess out of management this morning, will let you know how that goes :)

It's now official - Hyundai hate you:eek: one human being cannot be plagued with this amount of fuck ups and downfalls on a car!

Should i be writing the script for your next episode? I think Netflix would be glad to have your show streamed
 
Just came back from the Stealers. Convo went something like this:

Service Manager: Hello sir, hope you had a good Christmas. How may I help you?

Me: My vehicle was here for some work just before Christmas. It would appear that the undertray was not fitted *shows picture on phone*. Where is it?

Service Manager: Ah I see, not to worry this is most likely how it's meant to be. Some high performance vehicles do not have undertrays as they require more cooling

Me: ... What?

Service Manager: Let me just double check that with the tech department

5 mins later


Service Manager: Well this was embarrassing, yes it is meant to have one and it is currently sat next to the Master Mechanic's toolbox. Would you like this fitted now?

Me: yes...

FML...
 
@iiNNEX :| that’s so shoddy. I guess at least they still have it. How can you forget to put it back on???

Your hopes for Hyundai have been shattered XD. These people know nothing about the cars, much like the guy that told me "the car starts up in sport mode".... never talked to him again.
