My personal P5 required a new alternator last month. Looking forward to seeing how others are holding up with next month's update of our reliability stats.

To help provide the best possible information on your year:

Car reliability research

They tend to only provide it if they know the survey exists. I'm very thankful that many have been helping out.

We have updated results for the Protege 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.

In terms of repair trips per 100 cars per year:

2003: 90 -- about average

2002-2002.5: 80 -- about average

2001: 93 -- about average

1999: 92 -- better than average

Very small sample size for the 1999 and 2001, so these results are much less precise.

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.

Thank you, once again, to this forum and everyone who has been helping. We'll have further updates in November and February.

Looking forward to when we'll be able to fully cover all model years. 327 owners signed up so far, a very good start, but more remain needed.

To help provide better information on your year:

Car reliability research

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, updated reliability stats this month.

As always, the more owners participate, the better the information we can provide to everyone.

Updated results recently posted for the 2002 and 2003. They continue to require few repairs. Need more participants to include older model years.
