When it comes to rugged off-road vehicles, the Jeep Wrangler is an iconic choice. However, like any vehicle, the Wrangler is not without its faults. Over the years, different generations of Jeep Wranglers have experienced various issues that can be frustrating and costly for owners. In this article, we will explore the 10 most common problems with Jeep Wranglers, ranging from engine issues to electrical failures.
A Brief History of the Jeep Wrangler
Before diving into the problems, let’s take a brief look at the history of the Jeep Wrangler. The Wrangler we know today traces its roots back to the Jeep CJ, which was first introduced in 1945 as a military vehicle. In 1986, the Wrangler as we know it was born, with the YJ model becoming the first true Wrangler. Since then, the Wrangler has gone through several generations, including the YJ, TJ, JK, and the most recent JL.
While the Wrangler is known for its rugged capabilities, each generation has had its own set of problems. Let’s explore the most common issues faced by Jeep Wrangler owners throughout the various generations.
Common Issues with 2007-2018 Jeep Wranglers
The third generation of Jeep Wranglers, spanning from 2007 to 2018, has been considered the least reliable. This generation has received the most complaints and lowest-rated reliability among consumers. Let’s take a closer look at some of the most common problems faced by owners of 2007-2018 Jeep Wranglers.
1. Jeep Wrangler TIPM Failure
One of the most notorious issues with Jeep Wranglers from this generation is the failure of the Totally Integrated Power Module (TIPM). The TIPM is responsible for controlling various electrical functions in the vehicle, including the fuel pump, headlights, power windows, and more. When the TIPM fails, it can result in a range of issues such as fuel pump burnout, random airbag deployment, engine stalling, and malfunctioning power windows.
Unfortunately, TIPM failures are quite expensive to repair, with an average cost of around $1,200. Many owners have reported experiencing TIPM issues even while their vehicles were still under 40,000 miles. It’s important for Jeep Wrangler owners to be aware of this potential problem and take necessary precautions.
2. Jeep Wrangler The “Death Wobble”
The infamous “Death Wobble” is a terrifying experience that many Jeep Wrangler owners have encountered. It refers to a violent shaking of the steering wheel that occurs after hitting a pothole or braking hard. The cause of the Death Wobble is often attributed to loose or damaged steering components, such as ball joints, tie rod ends, and control arms.
Fixing the Death Wobble can be a challenging task, as there is no definitive solution that works for every Jeep Wrangler. Many owners have struggled to find a permanent fix, with some spending nearly $900 on attempted repairs. It’s crucial to address the issue promptly to ensure the safety and stability of the vehicle.
3. Jeep Wrangler TPS Failure
The Throttle Position Sensor (TPS) is a crucial component that measures the position of the throttle and provides information to the engine control module. When the TPS fails, it can result in various issues such as engine stalling, reduced power and fuel economy, hesitation during acceleration, and difficulty changing gears.
Replacing a faulty TPS is relatively affordable, with the part typically costing around $60. However, it’s important to address TPS failure promptly to avoid further complications and ensure optimal engine performance.
4. Jeep Wrangler Transmission Issues
Many owners of 2007-2018 Jeep Wranglers have reported problems with the automatic transmission. These issues range from the vehicle getting stuck in one gear to transmission slipping. While Jeep has acknowledged these problems and issued recalls, the repair process can be time-consuming.
In addition to transmission issues, the transfer case, which allows for 4-wheel drive, is also prone to leaks in the second-generation Wranglers. While a simple seal replacement costs around $30, a more extensive repair can cost up to $150.
Common Issues with 1997-2006 Jeep Wranglers
The second generation of Jeep Wranglers, spanning from 1997 to 2006, has somewhat fewer registered complaints compared to the third generation. However, there are still a few common problems that owners of 1997-2006 Wranglers should be aware of.
1. Jeep Wrangler Engine Popping
Engine popping, also known as backfiring, is a common issue in the second-generation Jeep Wranglers. This phenomenon refers to a burbling or loud gunshot-like sound coming from the exhaust. It is caused by the combustion of fuel outside the combustion chamber, often due to a faulty spark plug, incorrect engine timing, or an imbalance in the air-fuel ratio.
While engine popping may not cause significant damage, it can lead to power loss and decreased fuel efficiency. The repair costs for engine popping vary depending on the cause and damage, so it’s essential to have it checked by a professional as soon as possible.
2. Jeep Wrangler Body Damage
Jeep Wranglers are known for their off-road capabilities, and as a result, they are more prone to body damage compared to other vehicles. The first generation of Wranglers, produced between 1987 and 1995, is particularly susceptible to panel damage. While this is a natural consequence of off-roading, it can be costly to repair, especially if the entire door shell needs replacement.
Luckily, there are aftermarket body parts and panels available for Wrangler owners who want to restore their vehicles. Websites like RayBuck offer a wide selection of replacement parts specifically designed for 1987-1995 Wranglers.
3. Jeep Wrangler Oil Leaks
Oil leaks are not uncommon in older vehicles like the first-generation Jeep Wranglers. These leaks can occur from various components, such as the engine, transmission, or power steering system. Detecting the source of the leak can be challenging, as different fluids have different colors and characteristics.
Fixing an oil leak can cost around $100, depending on the extent of the damage and the specific component causing the issue. Regular maintenance, including oil changes, can help prevent or detect oil leaks early on.
Common Issues with 1987-1995 Jeep Wranglers
The oldest generation of Jeep Wranglers, produced between 1987 and 1995, is generally considered the most reliable. However, there are still a few common issues that owners of these Wranglers may encounter.
1. Jeep Wrangler Exhaust Manifold Bolt Failure
Exhaust manifold bolt failure is a significant problem in older Jeep Wranglers. Over time, the repeated heating and cooling of the exhaust manifold can cause the bolts to become loose or the manifold itself to crack. This issue can result in a constant knocking noise and may require the replacement of the entire manifold, costing around $1,000.
It’s worth noting that engine popping, as mentioned earlier, can contribute to the degradation of the exhaust manifold. Preventative maintenance and timely repairs can help prolong the life of the manifold.
2. Jeep Wrangler The Death Wobble
While the Death Wobble is more commonly associated with the third-generation Wranglers, it can also occur in older models. The same loose or damaged steering components that cause the Death Wobble in newer Wranglers can contribute to this issue in older models as well.
As mentioned earlier, addressing the Death Wobble promptly is crucial for the safety and stability of the vehicle. Consulting with a professional and conducting the necessary repairs is essential to ensure a smooth and safe driving experience.
3. Jeep Wrangler Ignition Switch Issues
Faulty ignition switches are another common problem that can affect Jeep Wranglers across multiple generations, including the older models. The ignition switch is responsible for various functions, such as starting the ignition, activating the fuel pump, and turning on electrical accessories.
When the ignition switch fails, it can result in various issues, including the inability to start the vehicle, engine cutoff while driving, or battery drainage. Replacing a faulty ignition switch is relatively affordable, costing around $130, and can often be done as a DIY job.
Conclusion
While the Jeep Wrangler is a beloved and iconic vehicle, it’s important for potential owners and current owners to be aware of the common problems associated with different generations. From TIPM failures to the infamous Death Wobble, each generation of Wranglers has had its share of issues.
Regular maintenance, timely repairs, and addressing potential problems promptly are essential for ensuring the longevity and reliability of your Jeep Wrangler. Whether you own a 2007-2018 Wrangler or an older model, staying informed about common issues and seeking professional assistance when needed will help you enjoy your Wrangler to the fullest.
