I would like to nominate the VW Passat B6 and Audi A4 for the appalling drain hole blockage problem from the bulkhead scuttle.
Water drains down into the CPU which is situated under the passenger floor and unless you are quick the car is a write off
Any Make - Worst Design Feature - NARU

The water leak into the passenger footwell of MX-5 Mk3s. Fortunately very easy to fix permanently.

Remove the plastic cover under windshield wipers. Find the plastic plug that the panel screws into. Remove the sponge type gasket between plastic plug and metal body and reseal with an acrylic sealant.

Best done on a preventative basis, before the water gets into the passenger footwell. Takes about 30 minutes.

BMW's swirl flaps - especially on the 30d engine, which would break after a few years and be ingested into the engine, wrecking it.

Strangely enough, when they were putting the identical engine into the Range Rover, they didn't fit swirl flaps on it.

Another one : Mercedes, for the automatic gearbox oil cooler being situated inside the radiator. A minor failure meant that your gearbox got instantly contaminated with water-based coolant, completely trashing it.

The VW oil pump connector on the 2.0 diesel engines. The slightest amount of wear, and it wouldn't work. New engine required.

Mazda's oil sump pick-up filter. Not usually changed at a service, and, again, blocks easily and leads to engine death.

There are a lot of these cases, it seems. All of the ones listed above could have been avoided quite easily.

Oh, another one.

BMW Z4 cabrio(first type). Some genius decided to place the motor for the roof into a plastic box (no lid) without any drain point fitted, and then to put that same plastic box in the side scuttle area, by where water runs during rain.

Box fills with water, motor sits in water for years, motor eventually fails. A pig of a thing to get to and change. A couple of 10mm holes in the bottom of the box - or even an open gridded box, would entirely eliminate the problem

We've come a long way since Ralph Nader's book 'Unsafe at any Speed' , I suppose only the OAP posters will remember it. Many years ago I had a car with a steering column which was a long rod starting a few inches from the chest and ended somewhere near the front wheel! Sadly, the UK motor industry did not pioneer the introduction of safety developments, e.g. airbags, seat belts, crumple zones etc.

As for engineering bad/impractical design, there have been many....not enough crank bearings, hollow camshafts, inboard disc brakes, water pumps in the wrong place, swing axle suspension, inappropriate use of crackable plastics and other poor original equipment failures known to experienced mechanics.......' oooh, they all do that...'.

Various Mercedes of the 90's, engine wiring loom made of a plastic which biodegrades after about 10 years in the engine heat, handily shorting the coils out which in turn spike output transistors in the ECU, leaving you with a miminum bill of £500 via an indy and repaired loom, £1000 if including a complete wiring loom and ECU repair or £3000 if you used the main dealer who only fit new ECU and complete wiring loom, ask me how i know all this, mine cost the middling amount but £1200ish cos had new coils fitted at the same time and the loom repair kit hadn't been made available at that time.

Still with Mercs, coupe's especially often have/had laminated rear screens with a multi wired element similar in how fine they are to a heated windscreen, element sandwiched inside, rear windows delaminate at the edges leading to various strands failing, you don't want to know the cost, think i'm on the third or fourth screen.

Still with petrol Mercs, same years, CHG degrading will allow oil into the water at around 100k, and you'd better get the oil cooler changed at the same time cos that will do the same thing at some point.

I'm an idiot, i worked on hundreds of cars in years gone by and realised long ago that Datsuns (i really don't know if its still the case, they haven't made anything i like for many years and i've had nothing to do with them), Toyota and Subaru made and still make cars with mechanical and electrical integrity even if the bodies rusted as all cars did at one time, barring some howling mistakes of their own in recent years, ie Toyota MMT gearboxes and CHG probs on 4 pot Diesels, and Subaru dabbling in Diesel.

Why its take me so long to return to older Japanese for the home fleet (bar the one remaining Merc i still can't decide what to do with, its cost me £thousands) i can't answer maybe me bumps need to be read, at one time we had three W124 Mercs, talk about glutton for punishment, the more upmarket the model the more they go wrong, the fairly basic E300 Diesel saloon we had appeared to be hewn from granite, completely trouble free.

I had a Landcruiser for years previously, nothing ever went wrong at all, that was written off (but saved SWMBO completely considering it wouldn't have made a single NCP star), why i didn't go straight out and buy another and stick with them for the rest of me driving life is a question that will bug me till the end of me days, i finally returned to Toyota 4x4's in 2007.

Some other makes lists of engines to avoid plus gearboxes of doom, one could probably write a book on, no up to a point it doesn't matter for those who buy new and change when the warranty runs out if it packs up 4 months later, but not all of us actually like new car designs for various reasons nor do we wish to support certain makers nor do we wish to keep paying out for depreciation, so long term durability concerns us more plus we prefer our own individuality whilst its still legal.

Copper injector seals on the Toyota d4d diesel engines eg. Landcruiser to about 2008.

The injectors on these cars sit in the oil in the head. As the car ages, the copper seals work harden and allow exhaust gases past. This gradually contaminates the oil, until the pickup filter clogs and the engine seizes.

Toyota (eventually) did a customer service campaign to change the copper seals to aluminium.

I nominate with great pleasure the gloriously pointless automated parking brake as fitted to many VW's, the B6 Passat being most worthy example of such idiocy. A cure for a problem that never existed and a barrage of hassle for owners to boot.

Picking up on Marlot's post about Toyota injector copper seals.

At one time Diesel injectors were screwed or clamped into the outside of the cyl head, just like an equivalent spark plug, there is no earthly reason i can see why that still isn't the case, any leaks of fuel or blow by become obvious long before they can destroy an engine unseen from the inside.

Toyota Safety System. This ADAS is touted as a safety benefit, but is very unreliable in some models, and verging on hazardous. It is affected by low sun, and brings up a flashing bright warning sign in the dashboard, and ceases functioning until the engine is turned off and then on again. In the rain, in cold weather and sometimes for no obvious reason, the useful automatic headlamp main beam system switches off, despite the windscreen being clean. Can be switched to manual, which required the selector to be turned through "off" whereupon all lamps extinguish. Dipped beam only when you need (and can use) main beam is not a strong selling point on unlit rural roads. Warning signs flashing up time and again are distracting.

It seems to be a problem with Auris and Avensis. Later designs, Prius 4 and CHR have a better basis (millimetric radar) apparently.

It highlights the fact that it is a dinosaur as far as modern life is concerned, trying to collect all the soot, stop the vibration reaching the drivers feet, clever electronics and high precision injectors to try to smooth the combustion, and although you might not feel the vibration from a diesel, it's still there under the bonnet putting a lot of stress on the electrical components and connections, which chafe and wear out quickly.

Thanks fo all your replies.

Surprised not to find the BMW 2 Litre engine mentioned with the chain cam at the rear of the engine which apparently can catch on the bell housing.

Can someone elaborate.

Any Make - Worst Design Feature - RobJP

Chain cams aren't a problem.

The problem comes with BMWs extended service intervals, which can see the oil in there for 20k miles at a time, by which point it's utterly useless. A few years down the line, all that additional wear caused by the oil being knackered causes the chain to fail. The chain is also lubricated by fine jets of oil being sprayed onto it. So, again, degradation/contamination of the oil leads to those fine nozzles getting clogged up, and the chain snaps.

The extended service interval was brought in for the fleet market to reduce ownership costs in the first 3 years. For no other reason. Once all that engine wear becomes a problem, the fleets have long sold the car.

It's highly noticeable that makers who stayed with short service intervals, even if they have chain cams, have far fewer problems.

Of course, the problem is largely eliminated if you use cambelts, rather than chains, but you then get additional maintenance costs that way instead.

The best way of avoiding the problems is by cutting the BMW oil change interval in half. So, instead of every 18-20k miles, get it done every 10k miles, or annually, whichever comes first.

I don't think that is a valid excuse RobJp.

A cut/paste from a Navarra owner's forum 2015 here:-

Finally got a reply from Nissan GB Customer services. Their spokeswoman told me that the chassis is not considered to be an integral part of the vehicle so they would not honour the 12 year anti corrosion warranty.

So for Navara D40 owners with rusted chassis rails , your wonderful 12 year anti corrosion warranty is not worth the paper it's printed on.

My chassis is so badly rusted , the garage are unable to weld it as there is nothing left to weld too. The corrossion from the inside out has spread over most of the rear chassis rails.

Any Make - Worst Design Feature - RobJP

As usual in these things, the devil is in the detail, however.

To start with, Nissan commercial vehicles - and the Navara is classed as such - are covered by a 6 year perforation corrosion warranty. Not 12. That comes straight from the warranty handbook, which is online. It also specifically states that the corrosion warranty 'covers body sheet metal panels'.

The warranty also states that the vehicle must be "inspected, and repaired if necessary, by an authorised Nissan dealer. Inspection and repair is required 3 years after the warranty start date and annually thereafter."

Finally, the warranty handbook quite clearly states that they belong to ADR (alternative dispute resolution), and that "If we are not able to resolve a dispute, we will refer you to Motor codes, a Chartered Trading Standards Institute ADR provider".

So all those people bleating on about Nissan not covering them for their chassis rails failing, I'll lay a pound to a penny that the annual inspections have never been carried out AND that the vehicles are well over 6 years old, or had been grossly overloaded. Because if they had done the inspections, then they owners be quite willing to go to Motor Codes, and Nissan would be told to carry out the work.

Regards the parasitic website ... erm, I mean solicitors website ... it's very notable what they do and do not say, and the very weasel words they use. It's also very noticeable that all their 'work' is on a no-win, no-fee basis, and they are 'investigating' whether people would have claims or not. Hell, if it was that obvious then they'd just be going for the throat.

I suspect that they're just trying to drum up noise - hey, it's free publicity.

They're also probably the most (in)-famous of the particular parasite ambluancus-chaserus-spivus. They have links up on their website for VW claims, the Emissions Scandal (their word, not mine, and a different one from the VW claims), Aerotoxic Syndrome claims (I'd never even heard of that one before I read their website), and lots of others.

If there was a real issue with vehicle safety, then VOSA would have done a recall. There have been 15 recalls over the years involving the Navara (both generations) however none of those include rust.

Here's one of the cases of an 'indignant' owner. 2005 Navara, owned from new. In September 2015 it failed. It had covered 22,000 miles a year in the intervening 10 years. The owner had to find his nearest Nissan dealership, as he had no idea where it was, due to the original one having closed down in the intervening decade. That tells you a lot ...

On the website where he ranted about it, others did the same .

Said child may also be car-sick in the back as the rear windows don't open at all. One wonders how an idiot like that stylist ever got a job at Citroen, let alone getting the design signed off.

Seat height adjustment. If you are going to design a mechanism to raise the seat squab, please design it so that the seat rises, not tip you forward like being tipped out of a wheel barrow. What's the point of just raising the back? Put a mechanism on both front and back!

And if it costs too much, get rid of something else like heated steering wheels, touch sensitive climate control, satnav (always ends up obsolete), electric parking brake e.t.c and spend it on something that really matters.

All the osteopaths and chiropracters should be thanking car manufacturers for keeping them in business.

Why do they change the seats in the next model when the old ones might have been perfectly good? The car might be new, but the basic human anatomy doesn't change.

It happens with running shoes. One year, you'll get a beautiful soft cushioning layer, then they change it for rock hard the following year, then it goes back to soft the next year. You could create a trend graph for this stuff! People get wise now and buy them by the pallet load in a good year.

Off-set pedals - so instead of sitting with your legs in line with your body your legs are shifted to one side - doesn't feel right and not good for one's low back..

That gets my vote - its just sheer laziness on the part of the engineers designing the car - if many other manufacturers can manage to put the pedals in the correct place for a similar sized car (or smaller/narrower), then so should they.

Number two on my list was the aforementioned cars that you need to go through the front wheel well (spending an hour doing so) to replace a headlight bulb, when it should be a 5 minute job accessible via the back of the light cluster by opening the bonnet only, as it was in my old K12 series Micra.

One additional one I found was on a neighbour's 99 plate Passat (I think a 'feature' on many VAG cars) whereby the battery is tucked right under the middle of the front windscreen, making it almost inaccessible to clamp jump leads to.

Not helped by the UK being a minority RHD country, especially in cars with relatively narrow footwells - still better than American brands who can't manage RHD at all!

While we are on the subject of offset pedals we mustn't forget offset steering wheels.

Thank you Avant a most helpful reply.

None taken btw.

FYI and phone/ipod users, this feature "button" does not exist.

And extremely difficult to lift the battery out and back again without putting your back out ! Not to mention a pesky plastic grill that gets in the way.

Perhaps that is why nobody cleans the drain holes beneath the battery causing the footwell and the electronic comfort control module to fill up with water

Pretty sure there was an old Citroen.....GS I think that you had to drop the engine to fit a new exhaust....only the French could think of that one.

We used to cut the front valance off and reweld it back on after, the exahust could be fitted ok but you couldn't get to the exhaust manifold bolts and they would leak at the manfold/head joint, and the bolts would snap off in the head for no apparent reason.
