Worst Cars/Engines

Firblog

Thought it might be useful for people to list what cars they've found to be very unreliable

My pick is the Mazda CX-5

OH has a 2.2 Diesel 141 model for 6 years now - Turbo replaced after @ 3 or 4 years old, and engine rebuilt last year (4K in parts alone, thankfully all paid for by Mazda) - have met 3 others who've had much the same problem with theirs - surely one of the worst cars going and anyone thinking of getting one should be told to AVOID.

Mazda made diesels were bad, but older 1.6 diesels were made / shared by Volvo, Peugeot, ford etc. These were reliable. Often reliability is based on specific engines rather than car brand or model.

Rover, range rover often win worst reliability contests.

BMW's N47 engine's timing chain wear resulting in catastrophic engine failures

N16 almera 1.5

An abortion of a car.

Mk6 Golf must be in with a shout. Probably an unpopular opinion but couple the dieselgate engines, especially 1.6 TDI and all the issues they had - with the chain driven TSI engines and if it was any other car it would be called a crock.

2.0 Pömpe Düse TDI

Yeah came to say the VW 1.2 TSI but its already been said.

Ford Ecotec of various sizes, disastrous fuel consumption.

Subaru Boxer diesel. Crap and why?

And all Jaguar Land Rover products from 1960 to date.

The 1.2TSI chain wasn't a bad engine, if the chain was done feck all else went wrong with them. The odd coil pack or HT lead.

The 1.2 chain driven polo was another story, although the 12 valve was a massive improvement on the 6 valve.

Actually I'd add the 9N polo to the list of crap cars.

Ford Ecotec? Never heard of one.

The twin charged 1.4 TSI was also awfully unreliable

Landrover freelander 1.8 petrol engine is certainly a contender, but the 300 TDI, 200 TDI and the td5 were good engines.

ah the ecoboost fuel consumption is a wider issue? thought it was just me :(

MacronvFrugals

VAG 1.4 TSI, the 170BHP one with the supercharger and turbo, absolute junk!

The Mazda diesels and insignia flavour 2.0 diesel are probably the worst commonly found out in the wild

For Forks Sake

That Mazda 2.2 diesel is an absolute dog.

I suppose we should mention the IS220d

Nowt wrong with the modern ones. Multi award winning unit.

I've driven one (155bhp) for a few thousand motorway miles.

Loads of performance and 50+mpg.

They were sketchy at best until 2017 ish and in fairness the stupid ignition key to open the bonnet idea was also award winning 😬

My shout is the Qashqai, sold by the boat load but non stop issues with corrosion and failed suspension and steering parts. Chassis made from chocolate.

The first of the dusters that were failing their first nct s due to rust issues , should get an honourable mention too

There were injector issues as well, plus the way it was mapped was ridiculous, no low down torque, plus crazy gearing that made 6th gear almost unusable.

The later 200d version of the same engine was a lot more usable and not nearly as troublesome

Nissan pulsar diesel. No power whatsoever. Woeful driving experience to boot.

Old diesel

The Isuzu 3.0 litre common rail diesel in its earliest incarnation in the Trooper was noted for giving issues.....

Also a Laguna II and 1.9 DCI engines could individually break your heart. Combine the 2 and its sad times.

bladespin

Early naughties Ford TDCi, literally ate their injectors.

They’re supposed to be like that though!

What an abomination!

Landrover ingenium engines are self detonating all over the world at the moment. Timing chains or balance shaft issues or both.

I'm a independent Land rover specialist, but I will only service a ingenium equipped car after informing customers that its likely to fail soon. Perfect oil and genuine filters make no difference. Detonating with full dealer service history anyway.
