1984 JAGUAR XJ
This model year
What the record shows
The 1984 Jaguar Xj is a subcompact car, and the 16th model year of a nameplate NHTSA records from 1969 to 2023.
The EPA rated two configurations: a single 4.2-litre six-cylinder engine, a single transmission, Automatic 3-spd and running on regular gasoline.
Combined fuel economy is 15 mpg.
The federal record holds 1 owner complaint and 37 service bulletins for it.
Counts are reports, not rates. A complaint is something an owner chose to file; it is unverified and unadjusted for how many of these cars were sold, so the useful comparison is against other model years of the same car. Recalls and investigations carry more weight because a manufacturer or regulator acted on them.
Reading this report
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
