Chatting to a GF driver today about most common and least common vehicles for breakdowns. Ford Focus and Nissans he sees the least. Number one for breakdowns won't come as a surprise to anyone here - L-R Discovery, followed by BMWs and Mercedes. Many electrical issues with the two Germans. Electric vehicles are a nightmare to recover, so breakdown in one of those.

There was a piece on BBC South recently covering the special requirements for recovering an EV. Can't recall if it was the AA or RAC, but they had universal freewheeling hubs and spacesavers to be fitted to the non lifted wheels to enable towing.

The piece also covered additional training being given to fire crews on the methods of chopping up EVs to release trapped passengers. Things like avoiding cutting through high voltage cables and the effects of having most of the weight between the wheels rather than over the front wheels when you cut the roof off.

IIRC an AA member designed the freewheeling hub, and for the cars that run out of juice the AA carry on board generators to charge them, not certain of charging times but would depend on generator ?

Interesting,
I was chatting to a bloke in the motorway services working for a recovery company (he tipped me off where I could get fuel without a long queue during the recent fuel shortages), he said he has more call outs for Mercedes than any other car or as he put it Mercedes cars ‘eat themselves’.

Can't say my Mercs have been unreliable, I'm on my 5th and they have been no better or worse than any other make I've had. 2 C classes, admittedly one got some rust but to be fair Mercedes fixed it without charge. Clk 320 never let me down in 6 years and an SLKd was fine except that when pooch came along we couldn't all get in so changed to present E class summer last year and it's been good as gold.

As a bus driver who frequents the local motorway network to Glasgow I see a clear pattern to broken down cars lying by the side of the road. Mini’s, BMW’s and JLR products are all by far the most frequent lay-by ornaments I spot. It’s very unusual to spot a Toyota or a Honda beyond the occasional flat tyre.

There have been some pointless threads on here lately and this is one of them!. I suppose the best vehicles are the ones that keep going?

I know a chap who up to fairly recently was a GF recovery agent. In his opinion the cars that are the least likely to break down are Hondas.

His main comment, though, was that cars break down not because they've been badly serviced but because they haven't been serviced at all!

The shift to tyre repair kits and no spare wheel must have added to the call outs. Along with the skinny tyres fitted to many cars which get easily damaged when hitting a pothole or kerb.

At one time motorists would accept changing a wheel as part of everyday life except on motorways but nowadays some cars have to be recovered to tyre depots who stock the right tyre.

in the case of my friends MB estate with 19 inch wheels and 35 profile tyres this involved a trip from Northampton to Leicester !

There are a couple of key drivers which make some cars more prone to breakdown. JLR, BMW, Merc produce more expensive cars which need to be differentiated from the "run of the mill" often by:

  • increased complexity to maintain technical advantage
  • adoption of new technology - buyers of premium motors need to feel their expensive purchase is justified

These both make their vehicles more vulnerable to failure. I get the impression that although many "equivalent" Japanese cars are not dissimilar in price, they prefer to put the money into better quality engineering than gizmos.

I notice that even the headlight connector on my toyota has a waterproof cover, and the connector also has a smear of dielectric grease on it.

By contrast one of the main engine connectors on my citroen van has no cover, and is open to the elements. It's not surprising that the vehicle has a reputation for electrics issues. I've given the connector a spray of ACF50 which will hopefully improve my chances a little.

What would be even nicer is for manufacturers to make their plastic lens covers of material that does not degrade (so much) by heat and the sun, and can be separately replaced from the entire unit at a reasonable cost when required.

Sanding down and 're-treating' the surface to make them 'good as new' often is a short-lived 'fix' and, unlike in the US where the materials required are dirt cheap, they are quite pricey in the UK.

My Mazda3 has a cracked fron fog lamp lens cover (it still works) due to an errant stone hitting it, but only some dodgy-sounding East European 'sellers' on ebay sell the 'part' (sans bulb), which you need to jack up the front of the car and take the wheel well cover off to fit. My local dealership wants £150+ to fit a whole new assembly. In the 'old' days, this would've been a 5 min job taking off two screws and refitting a (glass) new lens cover, which would not be affected by sun damage as my headlight covers have been.

At least I can change out the headlight bulbs without much fuss, not that (touch wood) I've ever needed to as yet.

Agree to a certain degree, complexity adds to the likelihood of failures but other prestige brands manage to do the job better. I don’t see many Lexus products or Volvo's sat with their necks broken in lay-by’s. Though I did have the pleasure of a shot in a colleagues Jag XF 2.0d yesterday and I see they haven’t lost the knack for building cars that are both sporty and fun to drive yet ride properly, something few firms can combine these days. I get the appeal despite the potential woe.

Anyone thinking of buying a BMW I3 EV is advised to do a lot of research.

Launched in 2013 , the ones with a petrol engine range extender had a fuel tank in the front with a filler cap kept closed by a solenoid to reduce emissions into the atmosphere. BMW was so confident in their electronics that as a standard feature from new they added a string operated petrol flap release in case the solenoid failed and the petrol cap remained closed. (!)

Surprise : many new owners find the solenoid fails and they have to use string to open the cap on a >£30k car.! A new solenoid of course is ££££s

And engine mounts on the electric engine failed (weak bolts) etc.

My advice don't buy a BMWi3 - or if you must, only the post 2016 ones.

Remember Germans use only the best string in their cars.

Only got to look what cars are popular in the States and apart from the home grown pickups they are mostly Locally assembled Japanese.

No French or Italian stuff to be seen in any quantity as their “Lemon Laws” have seen the importers running back home !

""Agree to a certain degree, complexity adds to the likelihood of failures but other prestige brands manage to do the job better. I don’t see many Lexus products or Volvo's sat with their necks broken in lay-by’s""

Again the whole argument is about volume of sales. The two mentioned are not volume sellers so the odds of seeing them moving or broken down are very low.

Both Lexus and Volvo are volume sellers of cars

Both Lexus and Volvo are volume sellers of cars

Lexus had a record high UK market share in 2020 - 0.84%.

Volvo had 2.85%.

Both BMW & Mercedes ~7% each.

Which makes them volume sellers...they are mass produced cars in huge factories and produced in the thousands...these are not small hand made manufactuerers.

Wasn't the simple point being made that the denominator is considerably higher for BMW & Mercedes than for Volvo & Lexus?

It wouldn't signify a big difference in reliability if you saw 7 times as many conked out BMW's as Lexuses, or twice as many as Volvo's, would it?

That said I'd far rather have the Lexus. In reality you'd probably see at least 20 times as many broken down BMW and Mercedes as Lexus, but unless you're a tow truck driver it's a fairly rubbish way of measuring reliability. I can only remember seeing one broken down car in the last year or two, and that was a VW Up.

The original point from Sammy was saying that Lexus and Volvo are not volume sellers and you are unlikley to see many of them moving let alone broken down...Volvo are Lexus are hardly cars you don't see every day...especially Volvo.

No. The point was the SMALL volume of sales of Lexus and Volvo compared to the total cars manufactured. Volvo 2.85 Lexus 0.84 total 3.69% for the two 96.31% for the rest. Far fewer cars around to breakdown. I don't remember the last time I even saw a Lexus!

Other than the large makes like Ford and VW most will only have a few percent market share. If you drive a lot you do see quite a lot of breakdowns and someone that works for a break down organisation will get a feel for what cars tend to have more problems.

Keep your eyes peeled for a Lexus plenty about to see :-)

I have yet to see a broken down Toyota Prius at the roadside.

Even bearing in mind that these vehicles used as taxis often run 24 hours a day with different drivers and clock up huge mileages , often up to 500 k.

In my mind the Toyota And Lexus equivalent hybrids must be the most reliable vehicles on the planet !

You must have missed mine then, a few years ago, dash lights came on returning from Heathrow on the M40. Stuck there for a while before being escorted back home by the AA. Eventually our local dealer found a short circuit between the high and low circuits. £400 to fix it, followed later by £660 (yes!) for a wheel bearing, I did 110k miles in it, an extremely uncomfortable driving position for a tall chap like me. I very much like Toyotas, but not this one. I plan a Lexus at some time though.

..................... followed later by £660 (yes!) for a wheel bearing,

I think the last time I changed a wheel bearing on one of my cars was circa 1982 on a classic Mini. Cost about £15.

Never had one go since.

Green Flag - Best and worst vehicle for breakdowns - Steveieb

I’m shocked to hear that about the Prius.

My Indie told me he had to change a wheel bearing on a Lexus and the genuine part cost approaching £1000 so he matched the original up with one from the local bearing supplier for less than £20.

But we don’t see many abandoned Hi Luxe’s in war zones on the TV !

Maybe they were just lazy? :-) I might've said that perhaps the filling station was out of whatever fuel they needed, but I think that 'crisis' has now ended (for the moment).

TBH I'm surprised that there hasn't been more cars with punctures over the last 18 months, given how many cars have sat idle for months on end, either getting flatspots and/or severely deteriorated tyres because they've been left to go completely flat.

Or flat batteries for similar reasons (lack of use). I did come across one person in my town (other than myself [July 2020] - but then my car's battery was around its historical 'replacement age' anyway) whose car also had a flat battery that needed replacement, otherwise that's it round my way.
