Jeep Cj5
1979–1979
Data Availability
Milemark has only 1 classified NHTSA complaint for the 1979 Jeep CJ5. This is not a reliability endorsement—it reflects the vehicle's age, low production numbers still on the road, and minimal owner reporting to federal databases. We cannot draw meaningful conclusions about failure patterns from a single data point.
What We Know From Recalls
No recalls are on record for the 1979 CJ5 in our database. This may reflect the vehicle's age and limited federal oversight in that era, rather than absence of defects.
Technical Service Bulletins
We have 26 Technical Service Bulletins on file. These manufacturer-issued documents address known issues and service procedures, though specifics require individual TSB review. They represent the strongest available signal for common problems on this model year.
How to Research Further
For a 45-year-old vehicle, prioritize: a thorough pre-purchase inspection by a mechanic experienced with vintage Jeeps, consultation with CJ-specific owner forums, and a detailed maintenance history review. Rust, frame integrity, and outdated safety equipment are typical concerns for any vehicle of this era.
Trends
Complaint trends by era
← All yearsClick a window below to see complaint data scoped to just those years.
5-year windows, not manufacturer generations — this database doesn't have reliable platform/redesign data to draw real generation boundaries from. Recent model years show fewer complaints mainly because they have been on the road less time, not necessarily because they're more reliable — read this as complaint volume and mix by era, not a reliability trend.
What breaks, and when
Median onset: 50,000 miles.
Typically $200–$6,500 to fix a transmission repair, nationally.
From owner-filed complaints to NHTSA, not independently verified. Federal mileage reporting on recent complaints is sparse — see methodology. Cost ranges are national estimates from book labor hours and parts pricing, not this vehicle's actual repair history — they don't account for your location or shop type.
