I hadn't used my car for a week until yesterday.
Drove to a meeting (20 miles) and it started making an odd screeching noise intermittently.
Called up the garage who said bring it in after the meeting.
On the way back to the garage (10 miles) the noise stopped and a dash light started to flash - the orange "A" in a circular arrow (stop start system).
So I thought it was something like the water pump belt (not over-heating) or alternator being being a problem.
I called the garage today to see when I could expect my car back. I was passed to the service manager - never a good sign.
Apparently a crankshaft pin has broken and the crankshaft needs to be replaced with a number of pulleys?
The car didn't lose power.
Hyundai will be providing a courtesy car as the repair is expected to take a week! The car is 3.5 years old and luckily still under warranty!
Is there anything that I should be concerned about? (Timing is terrible - I will post about in another post over the next few days).

A quick Google suggests previous recalls by Hyundai for crankshaft issues albeit these were in the US so models/engines may be different.

Just amazed they are saying they can turn it round in a week. Both the last main dealers (not Hyundai) I used over the summer need four weeks notice or more even to look at an issue. I hope it all goes well.

Love ClasicPete's .sig in that link. Not a jot of embarrassment. I'm not sure that the Allegro is all that rare though. I thought that all Allegros semi-worked?

Kia have the same issue with presumably the same engine.

Well they wont be changing the crankshaft, wont be available as a part, and the dealer wont have the required skills. If it needs a crankshaft, its a replacement engine. Hope your service history is faultless so they cant wriggle out of it.

Garage says it is.

To clarify - garage says it is covered as service history is complete. Always a worry though Zero as service histories are now electronic and I can't see mine and have a service plan, so can't easily prove that I paid for a service at a particular time.
Get your point re the replacement engine - probably much easier to do than stripping down an engine.
I have been to a professional engine re-furbishers. They were sent dead engines by car manufacturers and re-built them to the manufacturers standards.
I suspect it will be a re-furbished engine. I am not sure how I feel about that.

If it's rebuilt to manufacturers standards I'd be quiet happy with it.

Given it will only last 3 years, it doesn't appear to matter :-)
I assume that there is some sort of drive pin for the aux belt pulley that has sheared off, possibly damaging the end of the crankshaft.

Traditionally, a Woodruff key was used for the purpose. I wonder if Hyundai have found another (seemingly unsuccessful) method?
I believe other manufacturers have just used a taper fit pulley on the crankshaft end with resulting failures.

>>Woodruff key...
Thanks BT - learnt something new today! :-D

It would appear so....

Get it repaired, then chop it in for something else!

As RoR says as long as it's properly rebuilt and you've still got the balance of the warranty I'm not sure I'd be bothered. Better than having somebody who lacks the skills try and fettle the original and make a hash of it!!

Rest easy if you have a service plan. The dealership will want to make sure that everything that should be done, is done - but nothing more. They will charge the service invoice value to the service plan company, who will then vet it to make sure that the manufacturer's requirements have been met. It's the easiest way to cover your backside in the event of something like this happening.
I would be sceptical of suggestions that a replacement engine would be fitted; at the MG dealer I work for we only replace the parts that have failed. Our common warranty jobs are MG3 and ZS clutch arm bushes (gearbox out job), older MG3 cam chain stretch (new chain/pulleys/guides plus 8 hours labour), ZS headlamps for LED DRL failure, and HS infotainment screens. I would expect the Hyundai workshop techs to know exactly what needs doing and to restore the engine to perfect 3-year-old health.

Thanks!
I spoke to the dealership yesterday re time scales (I miss my car - I am too worried about scratching the loan car).
They said that they are still waiting on Hyundai to authorise the repair but that they were being slow. They don't expect any problems - just a slow process apparently?
They also said the problem is no where near as serious as they previously diagnosed - but I couldn't get any detail out of them. - the service manager was tied up and as I was out for the day - call backs weren't going to be practical so I didn't ask for one.
I may pop over on Monday to see what's going on.

If they are waiting for approval, and its taking a while, it means its every bit as serious as they previously diagnosed.

Yep.
I went to the garage earlier and saw the car up on the ramp, engine out.
The engine was in pieces and the new crankshaft was about to go in. It does look slightly different to the old one with a thicker pin at the end.
Mechanic said he hasn't experienced any problems with the new design.

Saw (glimpsed) the bill meant for the owner (me).

Give or take a few Pounds, £4,500! Plus VAT!
Dealer confirmed that Hyundai will be paying it. I suspect that there will be heavy discounts to the manufacturer, reducing that.
Ouch!
