How important is car reliability to you?

What’s your priority when it comes to buying a car? Good to drive, hugely practical, cheap to run? But where does reliability factor into your car buying decision?

A few years ago, reliability wasn’t particularly high on my requirements when it came to purchasing a new car. And this might explain a few things about my car history.

This includes two Alfa Romeos, with the latter being a diesel GT Coupe that I owned when I started at Which? in 2010. On my first day I was asked the most important question by the team: ‘what do you drive then?’ And even though I failed to tell them that my car had broken down on the way into the office on that very day (it went into ‘limp home’ mode on the A1 due to a faulty lambda sensor), the team still met the Alfa Romeo GT revelation with grimaces and ‘oohs’.

This is because the team had their own crystal ball for predicting the pain I had in store and the almost inevitable expenditure I was about to endure through owning an Alfa Romeo. And this crystal ball was, and still is, the Which? Car Survey.

My unreliable Alfa Romeo

For the last five years our survey has been the UK’s largest for car reliability, and Alfa Romeo has consistently propped up the table among the least dependable car brands.

Being a car nut for numerous years, I was fully aware of the stigma Alfa carried. However, I assumed it could only be horror stories of an affected minority, who’d bought bad cars that had slipped through the production line. But the depth of feedback provided through the survey meant the Which? Cars team was well informed to tell me that I had a high chance of facing a future of reliability woes.

And they weren’t wrong. In fact, when a minor service interval rang in at over £1,200 some four months into my Which? career, I decided it was time to part with the GT. In the year I’d owned it, I could have counted on two hands the number of days it ran without a warning light appearing on the dashboard.

It came as no surprise that my replacement car had a glowing reliability track record in the survey. I’d turned my head towards reliability and away from striking looks, outright performance and the colour of the leather interior. And my new car didn’t disappoint in a year and a half of ownership, costing me no more than £300 in servicing and minor repairs.

Which? Car Survey 2013

That’s the real value of having feedback from thousands of car owners. Any car journalist can tell you how good a car is to drive, how efficient it will be and how much shopping you can fit in the boot. But none can tell you how reliable a car will be like the 39,292 thousand car owners who responded to last year’s survey.

So, not only would I like you to fill out the Which? Car Survey (you’ll be entered into a draw to win a year of free fuel), I want to hear how important car reliability is to you. Does it top your car buying concerns or are you more interested in looks, price and mph?


For me I look at a few factors when choosing a car:

The most important ones are reliability, servicing costs and running costs (mpg, tax, insurance).
Finally I’d look at comfort and performance.

My current car I bought new for the first time. I spent ages with the Salesman, asking questions like does the car have a timing belt or a timing chain? Mine has a chain which is a plus point as replacement of that being needed is unlikely, whereas a belt needs regular replacement and is expensive.

Long service intervals are also important to me, due to my high mileage, and I don’t want to be servicing it 3 times a year.

What type of tyres does it have? If they are expensive tyres then that’s bad news.

My list just goes on and on. My priorities are all about running costs. The car is a tool to get me from A to B. I wish I didn’t need a car, but unfortunately I do, so I just want to get in it and drive it, and take it to the garage as rarely as possible!

I’ve been driving a long time, and there are certain makes of car that I won’t touch with a barge pole, based on either experience or from what I’ve heard from others. Those being italian or french cars!


Like rich835, reliability and running cost are important to me. Compared with most people I don’t do much driving and I don’t think I have ever driven over 10,000 miles in a year since I got my first car in 1979. I keep costs down by keeping cars for up to ten years, so I can afford to buy new ones despite the high depreciation. The last time I called out a breakdown service was in 1990, even though I have not paid much attention to car reliability ratings when buying cars.

I have done most of my own servicing and repairs, except that I have had work done by main dealers for vehicles under warranty. (I know it is not necessary to use a main dealer but it helped me get a new short engine for the cost of installation on a three year old car.) DIY has saved me a lot of money.

My main concern is about the proliferation of electronics in modern cars. Within three months of buying a new car I’ve started to see erratic behaviour of automatic headlights, automatic wipers and display dimming on the radio. Fortunately they work fine most of the time and none of the issues affects safety or use of the car. Industrial-grade electronics is incredibly reliable but I have not heard of a single major car manufacturer that produces models that are free from problems with electronic systems. As many people know, it can be difficult and very expensive to have a dashboard warning light problem fixed. The way forward is for manufacturers to give a lifetime guarantee on warning light systems, excluding sensors (some of which are prone to failure and can be replaced easily).

Servicing schedules are more for the convenience of motorists than keeping a vehicle in reliable condition. Many owners disregard regular servicing on older vehicles, but ask any mechanic and they will tell you that old cars need more servicing, not less.


If like me you have health problems, then the last thing you want is to break down. I have COPD and just diagnosed with type 2 diabetes, plus high blood pressure.
At 70 I cannot afford to be stranded for long.
Some of my past vehicles have been very reliable – Ladas (yes really),Mitsubishi, and now my wife and I both have Toyotas, which have never broken down in 9 years of ownership.
The worst were a Hillman Avenger from new (broke down driving it out of the garage), and a Ford.


Don’t forget to let DVLA and your insurance company know about notifiable medical conditions and keep them informed of any changes.

I have known quite a number of people who have continued to drive for years with diabetes. I’m no expert but understand that medication can lead to low blood glucose (hypo) and this can happen without warning for some diabetics, which could put themselves and others in danger.

It is worth mentioning that you have a disability if you have to contact a motoring organisation for help.


If the car isn’t reliable it won’t even get on my “go and see what it looks like” list.


Utility is my starting point – family size dictated a people carrier, which also has the advantages of being used as a family van, loads of luggage space for holidays, and a high driving position. Then evaluate the reliability and safety from the short list. Cost is a bit less important as I keep cars a long time and am then prepared to spend out on replacement bits when necessary. I’ve been lucky with two Renaults, beating the odds on their reputation – both 150 000m. The current one broke down just once with gear box failure at 100 000m – not happy but rescued by AA and not a horrendous cost to replace. Generally I forgive the car because it is versatile and not expensive to run. But what would I replace it with? Probably be looking for a 5-7 year warranty.

I reckon reliability is by far the most important factor in choosing a car. Fortunately I do a very small
annual mileage and so am unlikely to experience the horrors of a breakdown others seem to experience.Two Singer Chamois cars I owned in the 60s let me down badly, but otherwise I have
not had more than the occasional hiccup in recent years.My last 4 cars(Toyota Corolla, Nissan
Primera, Seat Leon and currently Seat Altea) have been exemplary. I do hear of problems with
french cars so I avoid them.Generally most other makes can be trusted not to break down.


I suffered many reliability problems for years in second hand fords and VWs.

I then changed to buy “nails”, as in, something under £1000. I went for Audi’s and for one 80 and 2 A4’s I suffered no breakdowns and no MOT failures/Service surprises.

I then treated myself to a much more expensive mini cooper s (I decided to go for driving pleasure over everything else) and regret my decision. The mini has had a full engine rebuild and new steering rack after just 45000 miles. The mini is alot of fun to drive, is really quick and has a great driving position, however it is the most uncomfortable, inpractical and downright over-priced car I have ever owned. There are many other faults with it (too much to list here) and I will be replacing it with a more comfortable/economical/reliable/practical car next year. None of this surfaced on the Which survey.

Reliability/quality may be boring, but it’s the one major factor that too many companies overlook in order to get it to the market for the date that the sales people have promised.

It is also worth noting that the internet is full of brand police ensuring that dodgy products are never bad-mouthed, Mini being a very strong case in point. Maybe that’s something that Which could look into?
