Source: NHTSA Office of Defects Investigation, public domain. Complaint counts reflect what owners reported and are not a measure of failure rate per vehicle sold.
What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.
Owners filed 3,915 complaints with NHTSA about the 1997–2006 Jeep Wrangler, and 2,446 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
Failures are spread across the mileage range, with the middle half between 25,000 and 78,000 miles. The median is 49,000 miles.
The most-reported areas are the fuel system (20.6% of complaints, typically around 42,000 miles), the transmission and driveline (9.7% of complaints, typically around 34,000 miles), the engine and its cooling system (8.5% of complaints, typically around 52,000 miles).
1 recall campaign cover this generation.
If you arrived asking “is it reliable?” — this page answers the version of that question the data can support: which problems owners reported, and at what mileage.
How many miles does a 1997–2006 Jeep Wrangler last?
Half of the failure reports on the 1997–2006 Jeep Wrangler were filed by 49,000 miles and 90% by 124,000 miles — figures drawn from 2,446 NHTSA complaints that record an odometer reading, so they time reported failures, not the cars whose owners never filed one.
29 reports (1.2%) came in past 200,000 miles — each one proof a Wrangler reached that mileage, not that it died there.
Before you buy a 1997–2006 Wrangler: the 3-minute check
Generated from 2,446 mileage-tagged complaints, 1 recall campaign, 4 documented problem areas. Print this page — the checklist survives print.

- Check engine (4.0l i6 cylinder head) on 2000–2004 cars. Cylinder head casting number 0331 is prone to cracking between the number 3 exhaust valve seat and the coolant jacket, causing coolant loss into the cylinder, misfire and overheating. The 0331 casting was used across…

- Check exhaust on 1997–2006 cars. 4.0L exhaust manifold cracking, typically at the rear runners, causing an exhaust leak and cold-start tick.
- Complaint reports are not spread evenly across model years here — see the by-model-year table below before you settle on a year.
- End with a pre-purchase inspection of this car. Aggregate data describes the population; the example in front of you has its own history.
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 25,000 and 78,000 miles, with a median of 49,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the fuel system and the transmission and driveline are where this generation's reports concentrate, so those are the areas worth a specific look. The transmission and driveline in particular shows a median failure mileage of 34,000, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

Which systems, and when
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 49,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
The fuel system accounts for 20.6% of complaints (805 reports, 624 of them with a mileage figure), with a median of 42,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 29,000 and 60,000 miles.
The transmission and driveline accounts for 9.7% of complaints (380 reports, 169 of them with a mileage figure), with a median of 34,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 7,000 and 74,000 miles.
The engine and its cooling system accounts for 8.5% of complaints (334 reports, 128 of them with a mileage figure), with a median of 52,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 30,000 and 73,000 miles.
The suspension accounts for 8.4% of complaints (328 reports, 251 of them with a mileage figure), with a median of 50,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 25,000 and 95,000 miles.
The steering accounts for 7.9% of complaints (308 reports, 229 of them with a mileage figure), with a median of 40,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 20,000 and 65,000 miles.
The electrical system accounts for 6.8% of complaints (268 reports, 155 of them with a mileage figure), with a median of 70,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 115,000 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2006 model year drew the most — 852 complaints — while 2003 drew the fewest at 130. The median year sits at 296.
That makes 2006 an outlier: roughly 2.9 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.
Recalls and what they cover
NHTSA records 1 recall campaign covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.
Reported severity
What owners reported alongside the failure itself, out of 3,915 complaints against this generation:
- Crashes
- 220 (5.6%)
- Fires
- 116
- Injury reports
- 166
- Fatality reports
- 12
These flags are self-reported by complainants and unverified by NHTSA; one report can carry several flags, so the counts overlap and do not sum to a total. They are not adjusted for how many of these vehicles are on the road. No chart is drawn here on purpose: overlapping counts spanning very different magnitudes cannot be honestly encoded as lengths.
Documented problems
Engine (4.0l I6 Cylinder Head) 2000–2004
Cylinder head casting number 0331 is prone to cracking between the number 3 exhaust valve seat and the coolant jacket, causing coolant loss into the cylinder, misfire and overheating. The 0331 casting was used across roughly the 2000-2004 build window.
Front Suspension / Steering 1997–2006
'Death wobble' - violent self-sustaining oscillation of the solid front axle triggered at speed by a road input, driven by worn track bar bushings, ball joints, tie rod ends or steering damper on the coil-sprung solid-axle front end.
Exhaust 1997–2006
4.0L exhaust manifold cracking, typically at the rear runners, causing an exhaust leak and cold-start tick.
Body / Frame 1997–2006
Corrosion of floor pans, rocker panels and frame rails in salt regions, commonly around the skid plate crossmember.

Aug 2015 · 2006 · Power TrainIf the vehicle unexpectedly moves there is an increased risk of a crash.
The defect. Chrysler (FCA US LLC) is recalling certain model year 2006 Dodge Viper and Jeep Wrangler and Liberty vehicles manufactured July 1, 2005, to July 31, 2006. In the affected vehicles, the springs within the clutch pedal position switch that prevents the vehicle from starting unless the clutch pedal is pushed down may break. As a result, the vehicle may not be started when the clutch pedal is pushed down or the engine may crank and start without the clutch pedal being pushed down causing the vehicle to unexpectedly lurch.
What can happen. If the vehicle unexpectedly moves there is an increased risk of a crash.
The free fix. Chrysler will notify owners, and dealers will replace the clutch ignition interlock switch, free of charge. The recall began on August 31, 2015. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is R13.
