What this means if you are buying a 2012 Xj

The 2012 is one of the stronger years for this model, passing 2.8 points more often than the Jaguar Xj average. That is a point in its favour, though condition and service history still matter more than the model year.

What a 14-year-old car fails on

A 2012 car is 14 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:

  • Lights and electrical: 10.36% of all cars tested
  • Suspension: 8.65% of all cars tested
  • Tyres: 6.23% of all cars tested
  • Brakes: 6.1% of all cars tested
  • Visibility: wipers, washers, glass: 4.65% of all cars tested
  • Body, chassis and structure: 3.18% of all cars tested

That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures. On a 2012 Jaguar Xj the average at test was 94,114 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.

The strongest year for this model is 2019 at 91.1%, and the weakest in our data is 2004 at 72.4%. That 18.7 point spread across the model's life is why comparing a 2012 car against a newer one tells you very little.
