We've updated our reliability stats for the GL-Class to include owner experiences through December 31, 2013.

Repair frequencies, in terms of repair trips per 100 cars per year:

2008 GL-Class: 147, high, small sample size
2007 GL-Class: 137, high, very small sample size

We'll have further updates in May and in August. The more owners participate, the more comprehensive and precise these will be.

Our reliability stats for the GL-Class now include owner experiences through March 31, 2014, making them nearly a year ahead of other sources.

Repair frequencies, in terms of repair trips per 100 cars per year:

2008 GL-Class: 110, high, small sample size
2007 GL-Class: 152, high, very small sample size

Thank you, once again, everyone who has been helping. Next update in August.

You really need to seperate the results of the GL320/350 from the 450/550.

True, it would be more useful that way but that makes the problem of small sample size a lot worse. [Small sample size makes the uncertainty factor on the statistics very high]

^ this, unfortunately

If we had enough owners involved, and the stats differed significantly, I'd separate them. We do this in other such cases.

We've updated our reliability stats for the GL-Class to include owner experiences through June 30, 2014 (making them about 14 months ahead of some others).

Repair frequencies, in terms of repair trips per 100 cars per year:

2008 GL-Class: 78, moderate, small sample size
2007 GL-Class: 169, high, very small sample size

Next updates in November and in February. The more owners participate, the more comprehensive and precise these will be. (I'd love to be able to drop the sample size disclaimers.)

We've updated our reliability stats for the GL-Class to include owner experiences through September 30, 2014.

Repair frequencies, in terms of repair trips per 100 cars per year:

2008 GL-Class: 93, high, small sample size
2007 GL-Class: 93, high, very small sample size

Additional participants would be very helpful. (I'd love to be able to drop the disclaimers and cover all model years.)

We've updated our reliability stats for the GL-Class to include owner experiences through the end of 2014. In terms of repair trips per 100 cars per year:

2008 GL-Class: 88, high, small sample size
2007 GL-Class: 66, moderate, very small sample size

We'll have further updates in May and in August. As suggested by the sample size notes, additional participants would be very helpful.

So, how have these cars been doing lately?

Our reliability stats for the GL-Class now include owner experiences through March 31, 2015. (Others are nearly a year behind.)

In terms of repair trips per 100 cars per year ("low" is best):

2008 GL-Class: 96, high, small sample size
2007 GL-Class: 66, moderate, very small sample size

No stat for a model year? Then we very much need more participants for it. Same for those with small sample size notes--so all of them. Next updates in August and November.

We've updated our reliability stats for the GL-Class to include owner experiences through September 30, 2015. Repair frequencies, in terms of repair trips per 100 cars per year:

2014 GL-Class: 27, low, small sample size
2008 GL-Class: 83, moderate, small sample size
2007 GL-Class: 53, low, very small sample size

Some recently suggested that we report separate results for the gas and diesel. As far as I could tell from our limited data, the overall frequency doesn't differ much between them. We really need more participants to make separate stats possible. With larger sample sizes the reported repair frequencies might also differ more.

We've updated our reliability stats for the GL to include owner experiences through the end of 2015, about eight months ahead of other sources. In terms of repair trips per 100 cars per year--lower is better:

2008 GL: 89, high, small sample size
2007 GL: 69, moderate, very small sample size

With more participants, we could provide more precise stats and cover all model years.
