Car passed Mot today, and did last year too. I'm thankful.
Is this normal?

Mine hasnt but when taking my dm car once it failed due to one tyre. Guy told me just to go and get it sorted and then come back. Which I did and it then passed. In NI so we have Mot centres. Due to a decision by the Minister who deals with MOT I got an exemption from my Mot for 1 year. It is an absolute nightmare trying to book your car for the MOT. If you wait for the letter to advise you it is too late.

We have a 12 year old Mazda 3 (almost 13 I guess, it’s a 62 plate) and it’s only ever failed once, 3 years ago. It was an easy fix though so passed the next day after the work was done. We know the brake pads will need to be done before the next MOT though so we’re getting that sorted soon.

The Corsa we had before the Mazda was a nightmare in comparison. Every single MOT it needed work done and it cost us a small fortune every year. The woman who crashed into it and wrote it off while it was parked did us a massive favour to be honest.

Mine's passed most years. Until this year. Big bill. 15 year old car. Had advisories and a few minor issues before but nothing major.

@Beepbeepoutoftheway so in 12 years your car was not serviced and passed every mot, so it never had tyres? Brakes? Other general wear and tear? Tyres over 8 years old need changing regardless of wear.

Unless it never went further than the end of the road you're talking nonsense! The oil filter alone will have rusted to dust in that time without a change.

The tyres were replaced when they needed changing. The oil was never changed. I'm not sure why you think it's nonsense when it was my car not yours. Quite bizarre you're getting so annoyed by it tbh.

My three year old Hyundai i10 failed its first one! Fortunately it's still under warranty. It took 2 months to get a new part!

Toddlerteaplease · 13/03/2025 07:06

It's serviced annually.

Because you have to. Your car manual specifies how often your car should be serviced. If you have a new car and don't get it serviced, it completely invalidates your warranty. Even if you don't drive your car a lot (mine does fewer than 4k miles a year) you should still do full service annually or at the very least top up fluids, change oil, power steering fluid intermittently.

You don't 'have to' at all! It's not a legal requirement. I would never buy a new car so the warranty is no concern of mine.

Yes a garage i use has said that SE Asian cars have have really issues getting parts, they recently had to wait 3 months for suspension parts for a Hyundai Santa Fe, required to pass an MOT.... there also isn't the after market OEM parts that are readily available for say a VW group car.

lily219 · 13/03/2025 07:25

It depends entirely on the age and condition of the car! If you maintain it well (check tyres, lights, replace broken wiper blades etc) and have it serviced, you stand a better chance of it passing but it's not guaranteed.

Dustmylemonlies · 13/03/2025 07:51

It's failed once. But it's an 12 year old car so I don't think that's too bad.

Shade17 · 13/03/2025 07:55

You quite simply do not "have to" at all. I've never had a new car, so never had a warranty to invalidate (a total scam anyway!) as they don't transfer to new owners.

This comment tells us you don’t have a clue what you’re talking about.

User19876536484 · 13/03/2025 07:59

Mine is old but never has. My husband makes sure there is nothing obvious it will fail on before he takes it in. One year he had to make a new exhaust pipe because there were none available in the UK.

Middleagedstriker · 13/03/2025 07:59

Our old Toyota did for 21 years. Never serviced it.

OK then.

Toddlerteaplease · 13/03/2025 09:18

@jasflowers it was ridiculous! It's a common car. However they got me a lovely hire car that I would never be able to afford to buy, and I did enjoy driving it. It was brand new!

angelspike · 13/03/2025 09:32

You don’t have to transfer a warranty to a new owner, it’s a manufacturer one with a new car. Usually 3 years

FrangipaniBlue · 13/03/2025 13:16

I've been driving since 2000 and never had a car fail its MOT......... I assumed this would be the norm but judging by this thread there are a lot of poorly maintained and potentially unsafe cars on the road Confused

Dreamskies · 13/03/2025 13:23

A service won’t stop you failing an MOT. Service looks at changing your oil, oil filter, fuel filter, air filter etc to keep the engine running well.

MOT checks for road worthiness - is it going to fall apart? Are any load bearing parts rusting through, do your lights work, do your doors open etc. They’re not the same thing and not really linked whatsoever.

Both should be done for different reasons. If you maintain your car and keep on top of any advisories then no reason for it to fail.

And critically - an MOT doesn’t mean there’s nothing wrong with your car! It does specific roadworthiness checks only.

Nodddy · 13/03/2025 13:25

22 years of Toyotas.

1 fail for a bulb.

I expect my Toyota to never fail. It is 5 years old. I expect it to last until it is 12 before it fails even a small thing.

Shade17 · 13/03/2025 13:40

They’re not, but a service will pick up a lot of things which could be MOT fails, there’s a lot of crossover.

It may well pick up some, but certainly not guaranteed to cover all of it or prevent a failure.

Obviously. But to say they’re not linked is just wrong. A service should include a lot of checks as well as the replacement of the service items. I wouldn’t expect a car that’s just been serviced to fail on bulbs, tyre tread depth of brake pad thickness for example.

Although, as I said previously, the best option is to MOT first then pick up any fails during the service.

Riverswims · 13/03/2025 14:59

what a redundant question? every year “your car” gets older and has done more miles so it’s likely to have more faults unless you’ve changed your car whereby it doesn’t need an MOT; brand new up to 3 years or other therefore it’s a different car so there’s no “normally” applicable 🤔

DinoLil · 13/03/2025 15:02

My car is 16yrs old and I only do about £1k miles a year 😆 so it usually passes.
