How we rated the best and worst Jeep TJ years

Finally, we went a step further to cross-reference the problem reports found on those sites with renowned automotive review sites like Kelley Blue Book and Edmunds, and we’ve gathered all that information to help us rank Jeep TJ years.

Most common Jeep TJ problems

The TJ is one of the best-selling Jeep Wrangler models out there, but it still had a few common issues that required the driver’s attention. Based on our findings and reliable platforms like Car Complaints, these are the most common Jeep TJ problems and the reasons behind them:

1. Oil leaks

One of the greatest issues that Jeep TJ owners have faced based on their reports is the oil leak situation. It’s mostly caused by the leaking seals and if not treated right, this issue could lead to complete engine stalling. While it’s a big and common problem for this generation and the 2002 model year in particular, Jeep never issued an official recall regarding this.

The main culprit was a stripped bolt which led to seal leaks on certain Wrangler models, therefore causing oil leaks that could harm the engine.

2. Transmission problems

You can be relieved if you thought that Jeep TJ had problems with the transmission system in terms of losing fluid and causing rough shifting. However, although it may seem like a minor problem, this generation of Wrangler had problems with the park pawl anchor shaft.

In other words, the shaft that’s used to hold the gearbox in park mode could move out of its place, causing the shifter not to engage in park mode. The aftermath is – your vehicle may roll over while parked and cause a chaotic situation on the parking lot or even the street.

3. Fuel delivery system faults

The air and fuel ratio needs to be precisely calculated by the car’s engine control unit (ECU) for proper combustion, and the same goes for the Jeep TJ. However, this sometimes becomes impossible due to faulty fuel delivery system components and it’s not just a one-time occurrence.

There have been numerous reports about drivers complaining about how the fuel pump goes out while driving and similar situations. Also, there have been instances of increased fuel pressure that negatively reflect the engine’s timing and combustion cycles, therefore shortening the life span of the engine.

4. Electrical problems

Finally, we’ve seen a fair share of NHTSA complaints about Jeep TJ’s electrical issues. There was even an official recall in 2007 about the faulty totally integrated power module (TIPM) that is Jeep’s equivalent of ECU. Upon the first symptoms of a bad ECU, these vehicles should be checked since this problem sometimes even causes engine stalling while driving.

On top of that, there were several other electrical system faults including malfunctioning dashboard gauges and fuel level readings.

Here’s our overview on the Jeep Wrangler TJ generation years to avoid so you can go and skip those while focusing on more reliable model years:

First-generation Jeep TJ (1997-2002 model years)

Some of the worst TJ generation model years of the Wrangler include the 1997, 1998, and 2001 model years. While the 2000 model year is a bit better, it’s still safer to avoid those model years and go for a 2003 or 2004 Jeep TJ model.

The biggest problems concerning these models started in 1997 with the poor labeling for recommended tire pressure and inflation labels. However, it continued with more serious problems including the fuel delivery system and the malfunction of the ECU. Electrical issues were most prominent for the 2001 model year, while the situation with leaking seals and oil leaks was mostly around for the 2002 model year.

Among the worst-rated models, the 1997 is by far the one with the most reports due to more than 600 complaints being filed by owners. The 2001 model comes right after that one since it also received quite a lot of reports – more than 400 complaints to be exact.

What are the best Jeep TJ years to buy?

There’s a bit of good news for all those who wish to buy a used Jeep TJ generation Wrangler since not all the model years were so bad. Moreover, a few model years are excellent in terms of reliability, especially when compared to those problematic model years we’ve mentioned before.

So, are you wondering which are the best Jeep TJ years to buy used? The best Jeep TJ years are 2003 and 2004, but here’s a full list:

• 2005 Jeep Wrangler TJ

Out of all the Jeep Wrangler TJ model years, the 2003 and 2004 models received the least driver complaints. We’ll take a look at each of these individually to help you with buying advice.

2003 Jeep TJ

The 2003 Jeep TJ is one of the best-rated models with a 4.6 out of 5 score based on 2003 Jeep TJ ratings posted by former owners. The model had a few issues with the suspension and heating system, but overall it only received around 130 NHTSA complaints.

2004 Jeep TJ

It’s safe to say that 2004 is the best Jeep Wrangler TJ model year so far, and it’s the most reliable option for those on the used car market. It had far fewer electric issues than the early-generation models, and the ECU issue was sorted out with the recall.

Also, the problematic situation with an automatic gearbox falling out of the park mode is fixed for later model years, and drivers even got a long-wheelbase model for the 2006 production year. According to 2004 Jeep TJ reviews, this model received a reliability score of 4.7 out of 5 again, and it didn’t have any major engine-related issues.

2005 Jeep TJ

The 2005 and 2006 model years are also quite reliable and they don’t have as many reported issues as 1997 or 2001. So, if you are looking to invest the least servicing efforts, you should go for a 2004-2006 Jeep TJ, and the 2005 model year is right there in the golden middle.

However, you should be aware of the fuel system problems reported by drivers, since although it’s the only major issue found with this model, it’s still something you should address before buying one.

Is the Jeep TJ worth buying?

As the time comes for the final verdict – yes, Jeep TJ is a model worth buying for its exceptional off-road capability and more than decent reliability. Even though there are some model years that drivers should avoid, it’s still a solid SUV. The most important thing is that complete engine and transmission faults are extremely rare, and the only thing worth examining in that sense are the seals and TIPM.
