Reliability research -- looking for P5s

One thing that bothers me about your site is that for the 2002 Protege for example, there are like 8 different engines listed (I'm guessing because people don't know exactly what it under their hood, so they guess). I think something needs to be done to cut this down so that you only have the option of the correct engines that were offered that year when you add your vehicle.

Good suggestion. This has already done, but wasn't in place initially. Also, note that these are powertrains. So the same engine with the manual and then with the automatic is two powertrains.

We'll have updated results soon. Additional participants always helpful.

Car reliability research
 
We have updated results for the Protege5 to include owner experiences through March 2009. In terms of successful repair trips per 100 cars per year:

2003: 44, better than average

2002-2002.5: 53, better than average

A big thank you to this forum and everyone who has been helping. We'll have further updates in August and November. With more participants, we could provide more precise information. This time around we were one response short of the minimum for the 2002.

259 Protege owners signed up, but we've only had enough responses recently to provide full results for the 2003. Current members have been selling their P5s. (I still have my 2003.) Any new owners who can take over where they left off?

Bad news on my personal P5: I've found rust starting around the inside edges of the wheel openings. Hopefully I can nip it in the bud. Less sure what to do about rust bubbles on one of the blacked out window frames.

I'm now learning that some of these cars could have used better rust prevention.
 
We have updated results for the Protege to include owner experiences through June 2009. In terms of successful repair trips per 100 cars per year:

2003: 43, better than average

2002-2002.5: 69, better than average

I do wonder, though, if many of these cars (like mine) have minor rust that has not yet been repaired.

A big thanks to this forum and everyone who has been helping. We'll have further updates in November and February.

Updated results again later this month.

We're going to start providing new stats for the odds of requiring no repairs and the odds of getting a lemon. These require larger sample sizes, so additional participants would be helpful.

Just noticed this thread and enrolled my car. I have an '03 Mazda Protege5 and am the original owner. I haven't filled out the repair survey yet, that'll have to wait until tomorrow but since I've got all of my receipts for any work that's been done, it shouldn't be too difficult.
 
No rust anywhere on my P-5. I live in No.Virginia.The car spent it's first years (till 2007) in St.Pete,Fl. 24,350 miles on it.It now has 35,100.
 
We have updated results for the Protege to include owner experiences through September 30, 2009. In terms of successful repair trips per 100 cars per year:

2003: 57, better than average

2002-2002.5: 79, better than average

2001 (sedan): 179, worse than average

Very small sample size for the 2001, which might explain the much higher reported repair rate. Or these cars take a turn for the worse after 100k miles.

We've also introduced two new statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.

For the 2003, the percentage with no repairs is about 57, and the percentage of lemons is about 3.

A big thank you, once again, to Antoine, this forum, and everyone who has been helping. We'll have further updates in February and May.

I still have mine. Do you still have yours?

Some fo the people who have been participating with their P5 have moved on to new cars. To keep providiing stats on the P5 we need more people who currently own one to sign up.

Own one and not yet signed up? Details here:

Michael, pleased to see True Delta in this forum. Your efforts are notably more in line with I expect to find in a reliability panel. My entries on the site have been worth the effort, and the info return has been more than that.

Couple of things you mentioned re: your '5.

1. Headlight bulbs should be readily available at any local auto supply; Autozone, Checker, etc. Bulb life in our cars is short and shorter, apparently as a result of an electrical anomaly that no one seems to be fully define, except for constant vibration from bulbs slightly loose in their wire retainers.

However, my last change six months ago to a pair of Sylvania Silver Star Ultras has lasted longer than any combination except OEM 55 watters, which were puny output and didn't last that long, anyway.

2. Rust. Have 136K and no sign anywhere, but I live in Colorado, as you know. No salt in the winter and very low average humidity helps.

I would encourage all forum members to register their vehicles on True Delta to further enhance TD's various applications, in addition to the reliability charts which are most informative, particularly the comparisons to other vehicle makes.

And a big tip of the chapeau to Antoine, as well, for making this forum THE Mazda gathering place on the 'net. :cool:
 
Funny you should bring up the bulbs. Just had the dealer replace both bulbs again yesterday. They lasted 22 months.
 
Just enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.

As always, more participants would be helpful. Updated Car Reliability Survey results in May, with a preview for participants next month.

We have updated results for the Protege to include owner experiences through March 31, 2010. In terms of repair trips per 100 cars per year:

2003: 75

2002-2002.5: 90

2001 sedan: 124

All are now about average. The repair frequency has been increasing recently for the 2002 and 2003.

Very small sample size for the 2001, which might explain the much higher reported repair rate. Or these cars take a turn for the worse after 100k miles.

We have two additional statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.

For the 2003, the percentage with no repairs is about 46, and the percentage of lemons is about 3.

We have updated results for the Protege5 to include owner experiences through June 30, 2010.

Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year.

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

2003: 90 -- about average

2002-2002.5: 80 -- about average

We have two additional statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.

For the 2003, the percentage with no repairs is about 52, and the percentage of lemons is about 9.
