The same model year, different builds

Every complaint carries the first 11 characters of the VIN — plant, year, body and engine. That is a production series, and complaints are spread across them very unevenly.

How we count

Every figure here comes from complaints owners filed with NHTSA — 1,100,006 of them, covering 1,982 models built between 1981 and 2026.

A complaint is an unverified report: someone wrote down what happened to their car. It is not a confirmed defect and not a recall. What makes the volume useful is the pattern — when thousands of owners of the same build describe the same failure, that is a signal no marketing brochure will give you.

Two things we do that the source does not. First, we compute the age of the car at the moment of failure from the incident date and the model year. Second, we group complaints by the first 11 characters of the VIN — the production series — so a bad plant run does not disappear into a model-wide average.

Frequently asked questions

What are the worst years for the XK8?

By complaint volume, 1998, 1997, 1999 drew the most owner reports. Bear in mind that popular years put more cars on the road, so check the crash and fire columns too.

Which XK8 years are the cleanest?

2003, 2001, 2000 have the fewest complaints on file. For recent years that can simply mean the cars are young.

Are these complaints verified?

No. They are unverified reports from owners. NHTSA publishes them as filed and investigates only a fraction. The value is in the pattern, not in any single report.

Can I check complaints for one specific car?

Yes — enter its VIN above. We match the first 11 characters, which identify the plant, year, body and engine, so you get complaints on that exact production series rather than the whole model.
