Japanese brands come out on top

UK-based Warranty Direct has gone over their data and released a report that details which companies build the most reliable engines.

According to their warranty claims, Honda builds some of the most durable engines as their failure rate is just 0.29%. Toyota and Mercedes weren't far behind as their failure rates were just 0.58% and 0.84%, respectively. Rounding out the top five were Volvo with 0.90% and Jaguar with 0.98%.

At the other end of the spectrum with the worst manaufacturers, MG Rover took the crown for building lackluster engines with an astounding failure rate of 7.88 percent. Audi and MINI fared slightly better as failure rates were clocked at 3.71% and 2.51%, respectively. Booby prizes were also awarded to Saab (2.49%) and Vauxhall (2.46%) for a less than stellar showing.

While all engines aren't created equal, neither is the cost to repair them. Warranty Direct says an engine failure in a Range Rover Vogue recently set them back £13,000 ($20,640 / €15,515).

Talk about hot topic! If you are a self-respecting worldcarfan, then you must know something called JD Power Satisfaction Survey! If the car brand you drive isn't at least in the Top 10, chances are you may have ended up with a liability! That's why a year ago, I advised my wife to buy a Honda Civic; she hasn't regretted it ever since! Hence it comes as no surprise why Honda STILL rule the roost! Great surprises from Fiat and Land Rover making Top 10! However, something isn't quite right about the positions of VW and Audi engines on the list. Since this is a British company, an element of bias in the statistics could be at play here! My MKIV Golf has hardly ever let me down except once in 7 years of ownwership! That engine starts first time and it's protecting my family in the current snowy weather conditions.

Lol Audi is second worst! Another reason I would ever buy one. 1.5 percent worse than BMW and 3 percent worse than mercedes.

A British report in which Jaguar & Land Rover are in the top 10!!! Sounds like a joke!

MINI has nothing to fear, BMW is making a new 3 cilinder Engines for them so they stop getting Peugeot Engines for their cars, ones BMW passes the first 24 months of test with the new Engine most of the problem will be sold.

it's interesting that only 1 honda in 344 had engine failure, but how you can compare this to 1 MG in 13 or 1 bmw in 45?. From a scientific and statistic point of view this study has almost two big bias: samples are not homogeneous and results are not standardized. so those numbers PROVES NOTHING

Bang on, the only way a study like this could be completed would be using the same sample size for each brand. This means you would have to monitor at least 1000 cars, each from the point they left the assembly line. You cannot select them after that because your selection process might skew your data. Again though 1000 is not a large enough sample, it would be more than 10,000 to get an accurate result. Then you run into a problem where Honda has a very limited engine range in comparison to something like BMW/Merc/VW, so which engines do you choose to monitor? You'd have to put a 2.0L I4 from honda vs a 2.0L I4 naturally aspirated from the competition. The one thing this study leaves out is the most important part of any statistical study, their sigma....

I own a Honda Civic and I could've never thought that Honda could top these brands by any means. Also I'm a Mercedes fan, so this is good news for me hahah! BMW is a disappointment though.

Ok every one here must have a car in the list which has 150k miles but that doesn't mean the whole brand is reliable. You have an 8 years old Aude A6 which done 250k miles yes it did not break down but Audi doesn't only build an A6.

I know a work colleague who destroyed an engine because he did not put oil in it. Is that the manufacturers fault?

Perhaps this percentage is also affected by the treatment a car gets from its owner. In my country mercedes, volvo and jaguars are far more expensive than opel (vauxhall) and so their drivers are more careful not to "hurt" their car. Besides all three brands are almost exclusively driven by older people ;-) Audis and BMWs on the other hand are expensive but they tend to end up in "heavy footed" drivers.

:D only brits can make report like this, lets keep in mind that 80% Hondas in britain are owned by old people who drives only once a week and not more then 5 miles... and also we now how brits look after they cars, some of them even does not now that engine needs oil... P.S. @MachinaeSupremacy absolutly right...

warranty direct provides cover after the original manufactures warranty has run out... just how old are the cars they cover? coz if my toyota warranty is 3 years and my volvo warranty is 5 years by the time i go to these guys in my volvo its older than the toyota... this data is unreliable, so many variables

My .94 Audi has done 415 000 km without any major issues. Test is stupid, as it shows which car owners service their cars properly.

And what was the most common claim for each make or overall? Cars are not simple these days, a lot of s**t can go wrong.

Curious to know how they came up with the percentages and the population stats of their clients. if it's number of engine failures divided by total number of claims per make doesnt it figure that if their clients drive more of a certain type of make then the engine failure rates are likely to be lower. coz i'm thinking how many toyotas vs saabs do they cover and one bad saab can ruin the percentages since they are likely to be lower numbers of saabs than toyotas. just saying %s may not be the best way for this sort of data.
