Hi all, recently purchased a second had Hyundai Tuscon n line 2019 (had it 10 days). Today went out to the car and it would unlock. Wing mirrors were opening but the car would not unlock. I proceeded to try with the key with no success. All the doors would make the sound of unlocking but would not open. Anyone know if this could be the key battery or the common fault with the latch? I will call dealers tomorrow to report it and see what they say. The car would still be under warranty with Hyundai so hoping it would be covered if something needs replacing. Thanks in advance

Welcome to the forum, ‘Kirstiew’.

Before contacting the selling dealer, I’d like to be able to rule out the fact of the possibility that the car doors might be frozen and stuck shut. It’s rather odd if you can hear the sound of the door locks actuating that none of the doors can open.

The other thing in my mind is that the sound you hear is that of the lock mechanisms trying to open but not actually managing it. Perhaps in this cold weather, the battery has run down sufficiently to be the source of the problem you describe but still has some power, enough to create the lock movement you hear and the door mirror action you have noted.

Have you attempted entry again since reporting the matter here? If you still cannot gain entry, then you may achieve it by removing the end section from the driver’s door handle and utilising the key contained in the fob.....(I’m presuming that your car has that facility but I’m happy to be proved mistaken.)

If you can gain entry, you will obviously be able to try and start the engine. If that happens, all good. If the battery is depleted, then you can access the bonnet cable and open it, allowing access in order to jump-start the engine or place the battery on charge if necessary.

Please keep us posted on progress.

Hi, I've got 2016 tucson premium with 45000 miles and both my drivers doors have the same problem, started with the front door and several months later now the back door. I found the technical bulletin from the US with the extended info and part numbers. It shouldn't matter what country your in but US like taking thing to court and getting things done whereas the UK nobody could care about the safety issues until something happens.

I have a 2023 tucson premium hybrid, and when I get out of the car and try to let the kids out of the rear, the rear doors won't open unless I press open on the key fob, even though both front doors are still open (as we have just got out of the car).
Is this a feature of the child locks, as I thought activation of them would only prevent children opening their doors from the inside?

It's possibly a feature of the automatic door locking once you reach a certain speed , if you want you can disable this via the settings on the car . Personally given the way things are I'd stick with the automatic door locking as pressing the unlock button on the keyfob , or, using the external door lock buttons on the driver / front passenger doors ( press twice, once locks the open doors the second unlocks them and the rear doors ) seems a small price to pay for the added security of not having some random person jump in to your car when you're stopped at traffic lights or similar , but that's just me :roll:

Did anyone get this problem sorted? My rear passenger side wont open at all, and two of the other have the problem intermittently, and the garage are trying to charge me £2,000 to fix it... despite it being a manufacturers fault, and affects all these cars! my car is from 2015 but the intermittent fault started whilst still under warranty... please help! It feels like what the garage is doing is fraudulent really, if not extremely poor service

What, if anything did the dealer do to alleviate the problem whilst the car was under warranty ?

I do wish people would cease chuntering about cars in the USA. Hyundai USA and Hyundai Uk are two separate companies and are run as such, even though the parent company in South Korea has overall control.
Also, whilst the cars destined for the USA will have some common parts with UK cars, many will be different, especially parts that cannot be seen.

Being blunt, these door problems are occuring on older cars which are well out of warranty, so unless you can contact Hyundai UK and get some goodwill help from them, you're on your own.
Taking this problem to a Hyundai dealer is always going to be the most expensive way to get a fix and so I'd recommend finding a standalone Hyundai specialist or a good auto electrician.

I should add here, that in manufacture, bad batches of a particular component do occur, whether through poor design or an actual manufacturing fault and poor QC.
It happened some years ago in the VAG where ignition coils were breaking down. If you went to a dealer whilst the car was in warranty, the faulty coil would be replaced, but if another one or more failed once out of warranty, you were on your own, unless VAG felt benevolent eonough to make a goodwill gesture.
Car manufacturers are not renown for their benevolence.

If there was a serious safety issue here, then a recall would have been issued - car manufacturers don't like being sued, it gets expensive.
