Hyundai have just today recalled 300,000 cars in the US due to dodgy seatbelts.
Now I realise it’s America… and they’re front seatbelts, not rear… and the Bayon isn’t mentioned as a model affected… but it just goes to show that these things happen. And who knows – maybe your Bayon ‘might’ be affected – it’s just that no one in the UK has reported a problem yet? For instance ; you would never have known if the MOT garage hadn’t pointed it out! And perhaps Hyundai’s seatbelts are sourced from the same manufacturer?
Just a thought. Here’s the article:
