Thanks, I appreciate it.

Updated reliability stats next month.

As always, the more owners participate, the better the information we can provide to everyone. Especially need more 2011s.

Starting this month we have a new question to measure, as objectively as possible, the severity of a problem. Many people have been asking for reliability stats that weight problems by how severe they are, and once we have enough responses with the revised survey we'll start providing this.

Also this month: updated reliability stats.

We've updated results for the GLK to include owner experiences through September 30, 2010.

With a reported repair frequency of 50 repair trips per 100 cars per year, the 2010 GLK remains about average.

Thank you, once again, to everyone who has been helping. We'll have further updates in February and May. With more participants, we could provide more precise results.

We've updated results for the GLK to include owner experiences through December 31, 2010. Other sources of car reliability information won't cover the months since last April until the summer or even fall of this year.

With a reported repair frequency of 38 repair trips per 100 cars per year, the 2010 GLK remains about average, but now not far from "better than average."

Thank you, once again, to everyone who has been helping. We'll have further updates in May and August. With more participants, we could provide more precise results.

We've updated our car reliability stats for the GLK to include owner experiences through March 31, 2011.

With a reported repair frequency of 34 repair trips per 100 cars per year, the 2010 GLK is now better than average and is perhaps the most reliable model Mercedes offers.

We'll have further updates in August and November. With more participants, we could provide more precise results and cover all model years.

We've updated our reliability stats for the GLK (on our redesigned site) to include owner experiences through December 31, 2011.

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

2011: 44, about average, small sample size

2010: 38, better than average

Thank you, once again, everyone who has been helping. We'll have further updates in May and August. With more participants, we could provide more precise results and cover all model years.

Owner surveys are flawed because they are prone to over exaggeration, misunderstood mechanics, and most importantly... bias. I'll pass.

Our survey participants engage in only an appropriate level of exaggeration

You are correct that these are risks. Our survey design has a number of unique features others do not specifically to minimize these risks. For example, where some surveys ask participants to report only problems they "considered serious," which opens the door wide for people to honestly under-report problems, ours asks for all completed repairs. The current stats also only count successfully completed repairs, where something was done to make the problem go away. In such cases it's highly likely that the car actually had a problem and not just a more subjective "it doesn't sound/feel/run right."

2004 Volvo XC70; 2012 GLK 350 4matic
2012 GLK 350 4matic. I am attempting to enter a totally satisfactory repair under warranty by a 100% satisfactory dealer, Star Motors in Houston, TX. Star Motors was perfect. I didn't even buy the GLK from them. I can't get there from here. Your database won't allow me to enter my experience.
Standing by.
Disregard. I was able to enter my repair under warranty.

I'm sorry for the trouble. The repair history form (which supplements the main reliability survey) still has some browser-specific issues that need to be worked out since a recent redesign.

I see a repair posted. Did you get it to work, or was the problem with a second repair?

Please contact me via the contact form on the site (link at the bottom of every page) so we can identify the specific problem with the form.

I got it to work when I went back a second time. Only one repair and I got the information entered. I'm using Chrome if that helps.

ps: I followed the repair link (http://www.truedelta.com/repair_history_survey.php - your repairs so far) in your welcoming email. That worked for me. I hope this helps.

Thanks, and again sorry for the extra trouble. We're currently working on a revision to the main survey, after which we'll be going over the repair history form again (to more seamlessly integrate the two, among other things). I'll keep this in mind when we do.

It seems like the emphasis at truedelta.com is on delta rather than true. Small sample size doesn't even scratch the surface for the potential problems in this site's fundamental premise. This is practically the definition of survey bias. How many people with zero car problems are surfing around the internet looking for a place to record that information? How much more likely are people with more disposable income (proxy for nicer vehicles) to have convenient access to the internet? Is there any attempt to normalize these data for such factors? Otherwise, pretty colored wedges!

If you can't afford the Internet, you can't afford a remotely new car. In general, time is a much more limiting factor than income. There's no direct connection between time and money and car reliability, though. This isn't a political poll, where time and money have clear relationships to the variable being studied.

On the implication that only people with problems are likely to report, this is a very common misunderstanding of how our survey works, based on how other online surveys work. People can't just visit the site, report on past problems, and affect the stats. This is an ongoing survey that collects data from the time someone joins. Pre-existing problems are excluded. Each quarter we strongly encourage everyone who has signed up to respond even if they have no repairs to report.

Because this method avoids the very real risk you mention, we have some car models where not a single owner has reported a repair in the past year, and quite a few where fewer than one in ten owners have.

Not many upscale German cars in the above group, just the 2012 A4.

I have two vehicles which I report on True Delta, one 6 years old, one a 2013 GLK. Neither has had any issues other than regular maintenance.

Thanks! Many members report no repairs for a year or two. Six is outstanding.
