TrueDelta Vehicle Reliability Survey results - Mazda CX-7

[P5w3kids]

The latest TrueDelta Vehicle Reliability Survey results have been posted. These are for the year ending September 30, 2007.

For the 2007 Mazda CX-7, I have an average of 4.5 months of data on 31 cars. The stat of 153 successful repair trips per 100 vehicles per year (1.5 per vehicle) is much worse than average for a 2007 model.

Most of the reported issues involved sensors and valves in the intake manifold. Not major problems, but they do affect driveability.

It is possible that Mazda will sort these issues out, and repair rates will start to decline. Results will be updated in three months.

Everyone who has been helping out with this research, thanks, these results wouldn't have been possible without you. Those who aren't yet helping out, I hope you'll consider doing so.

When looking at the TSB's and the vast differences in which cars apply is it fair to lump in all of them into this survey? What I mean is do later built cars show as much problem with the TSB's applied?

I have a 2/07 build which after looking many if not all TSB's are applied. So was just wondering.. Maybe I don't understand what I'm looking at or talking about (eek2)

recalls make it look worse then it is

I am a member of the survey and the only problem I had was the 2 recalls but that was the only problem I have had no gas cap no tpms problems . but when I got the survey I still had to put I had a trip to the dealer but I stilll love my cx7 .... have lots more room to go snowboarding this year and lots of room for my paintball stuff.

so it appears as though Consumer reports is correct.

The problem with sites like true delta is that people with a negative experience are FAR more likely to search out a means to express that dissatisfaction.

I mean compare the number of threads on this forum where someone starts a post about their car being great and nothing's wrong, to the number of thread where something is wrong. 100 to 1? 1000 to 1?

To be fair the survey would have to poll the dealers on how many repairs they made versus sales.

I have had 0 problems with my car, but I don't have time to fill things out on true delta. I looked at the site and put up a tank or 2 of MPG results... but I just have better ways to spend my time.

Thats better than "uncle", and rolling over to play dead!

I'm not sure I agree with this one though... maybe if you subtract every MPG, CEL, & gas cap thread(deadhorse

This is exactly correct. Generally only people with something to complain about use these surveys. This is why they are never accurate and usually worthless.

Recalls are not included in the analysis. So if you reported your repairs as a response to a recall notice, they did not affect the reported repair rate.

If you've had no repairs, then you certainly had time to report your experience. You could participate for an entire year in less time than it took you to write this post. Seriously. We're talking about four approximate odometer readings.

You click the link in the email to load the form, you enter a two-digit number, you view a couple of earlier responses to ensure they're still accurate, you click submit. Done.

Time isn't the issue.

As for only complainers responded, if this were the case then the reported repair rates would be high for every model in the survey. And this is far from the case. In any given month, only about one in ten people reports a repair. The majority of participants have never reported a repair.

One thing to keep in mind is that TrueDelta only collects data going forward. So even if people join because they've had a bad experience so far, this experience cannot skew the results. With the exception of the very first month, all that matters is what happens with the vehicle after they join.

Other surveys lack this design, and so are susceptible to the distortion you describe. But not this one.

Sorry I didn't respond sooner, but didn't have automatic notifications turned on

Recalls are not included in the analysis, but TSBs are.

With a recall, a repair is made even if nothing has broken yet, because there is a safety issue. I do not include recalls because I wouldn't want to give manufacturers further reason to not issue them.

TSBs are different. They merely specify how to fix a common problem once this problem has occurred. If the problem has not occurred, the dealer isn't supposed to do anything. And if it has occurred, then clearly there's a problem with the car that should be reported. Unlike recalls, TSBs are not proactive. They're reactive. And no notice is sent to owners alerting them of the potential problem.

Finally, note that I'm measuring the number of repair trips, not the number of repairs. So if someone reports a large number of problems in a single repair trip and/or has a number of TSBs performed at the same time, it still counts as just one repair trip.

Well I called my dealer to have some TSB's done and they said unless its a problem they don't do anything. He looked up my Vin and said there was a recall. Said to bring it in and they would apply the TSB's on the ECU so I got some TSBs done but they were not really a problem (wiggle)
