The 1993 Jeep Wrangler has no open NHTSA recalls. Owners report 6 recurring issue clusters, led by “Fuel tank and sending unit leaks.” Jeep vehicles use the Oil Change Indicator system to signal when oil is due. Wrangler and Gladiator owners who actually use 4WD off-road should treat the schedule below as Schedule A (severe) — water crossings, sand, and rock crawling demand differential and transfer case service at half the published intervals. Grand Cherokee and Cherokee follow the standard Mopar schedule.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads, rotors, and parking brake every 8,000 miles. Wrangler and Gladiator pads wear faster than Grand Cherokee due to higher curb weight per axle.

Occupant deaths in fatal crashes (FARS)
174 crashes 1990–2024
How the 174 occupant deaths break down
130
driver deaths
44
passenger deaths
174
occupant deaths
Crash years covered: 1990–2024 This model year first appears in 1993 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.
FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.
Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.
Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.
IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.
Owner-reported problem signals
Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
