The open road, the wind in your hair (or what's left of it!), and the reliability of your vehicle – these are the cornerstones of a great driving experience. But what happens when that reliability falters, specifically with something as crucial as your transmission? Many 2017 Jeep Cherokee owners have voiced concerns about transmission issues, leaving them stranded and frustrated. Let's dive into the details and explore whether these concerns are justified, what the potential problems are, and what you can do about them.

So, Are 2017 Jeep Cherokees Prone to Transmission Troubles?

The short answer is: potentially, yes. While not every 2017 Jeep Cherokee suffers from transmission problems, there's enough evidence to suggest that it's a common enough issue to warrant serious consideration. The primary culprit appears to be the ZF 9HP48 9-speed automatic transmission, which was used in many 2017 Cherokee models. This transmission, while intended to improve fuel economy and performance, has been the subject of numerous complaints and even lawsuits. The problem isn't unique to the Cherokee, as other vehicles using the same transmission have also reported similar issues.

What Kind of Transmission Problems Are We Talking About?

The issues reported by 2017 Jeep Cherokee owners range from minor annoyances to major malfunctions. Here's a breakdown of some of the most frequently cited problems:

  • Rough or Jerky Shifting: This is perhaps the most common complaint. Owners often describe the transmission as feeling hesitant or "clunky" when shifting between gears. This can be particularly noticeable at lower speeds or during acceleration.

  • Hesitation or Delay in Engagement: Imagine pressing the accelerator and feeling a noticeable delay before the vehicle actually responds. This hesitation can be unnerving, especially when merging onto a highway or navigating traffic.

  • Shifting into Neutral Unexpectedly: This is a more serious issue where the transmission unexpectedly shifts into neutral while driving. Obviously, this can be extremely dangerous, as it leaves the driver with limited control over the vehicle.

  • Failure to Shift into Certain Gears: Some owners have reported that their transmission refuses to shift into certain gears, limiting their speed and performance.

  • Complete Transmission Failure: In the worst-case scenario, the transmission can completely fail, rendering the vehicle undrivable. This often requires a costly replacement or rebuild.

  • "Lurching" or "Surging": A feeling that the vehicle is unexpectedly accelerating or decelerating, even with consistent pedal pressure.

  • Error Messages and Warning Lights: The check engine light or specific transmission-related warning lights may illuminate, indicating a problem. Diagnostic codes can help pinpoint the issue.

Decoding the Culprit: What's Causing These Transmission Woes?

Pinpointing the exact cause of these transmission problems can be tricky, as there are several potential contributing factors. Here are some of the most common explanations:

  • Software Glitches: The transmission's operation is controlled by a complex computer system. Software glitches or programming errors can lead to erratic shifting and other performance issues. Updates to the transmission control module (TCM) are often released to address these software-related problems.

  • Valve Body Issues: The valve body is a critical component of the transmission that controls the flow of hydraulic fluid. Malfunctions within the valve body can disrupt the shifting process and lead to various problems.

  • Torque Converter Problems: The torque converter is responsible for transferring power from the engine to the transmission. Issues with the torque converter, such as slippage or failure, can cause significant performance problems.

  • Internal Component Wear and Tear: Over time, the internal components of the transmission can wear down, leading to reduced performance and potential failure. This is especially true if the transmission fluid isn't properly maintained.

  • Inadequate Transmission Fluid: Low or contaminated transmission fluid can cause a variety of problems, including rough shifting, overheating, and premature wear. Regularly checking and changing the transmission fluid is crucial for maintaining optimal performance.

  • Manufacturing Defects: While less common, manufacturing defects in the transmission itself can also contribute to problems.

Okay, My Cherokee is Acting Up. What Should I Do?

If you suspect your 2017 Jeep Cherokee is experiencing transmission problems, here's a step-by-step guide:

  1. Document the Symptoms: Keep a detailed record of when the problem occurs, what it feels like, and any other relevant information. This documentation will be invaluable when you take your vehicle to a mechanic.

  2. Check the Transmission Fluid: Inspect the transmission fluid level and condition. Low or dirty fluid can often be a contributing factor. Refer to your owner's manual for the proper procedure. Important: Use the correct type of transmission fluid specified for your vehicle.

  3. Get a Diagnostic Scan: Take your vehicle to a qualified mechanic and have them perform a diagnostic scan. This will reveal any trouble codes stored in the vehicle's computer, which can help pinpoint the source of the problem.

  4. Consider a Transmission Flush: If the transmission fluid is dirty, a transmission flush might help. However, be aware that some mechanics advise against flushing high-mileage transmissions, as it can sometimes dislodge debris and worsen existing problems. Discuss this option with your mechanic.

  5. Software Updates: Check with your Jeep dealer to see if there are any available software updates for your transmission control module (TCM). These updates can often address software-related glitches.

  6. Seek Professional Repair: Depending on the severity of the problem, you may need to have the transmission repaired or replaced. This is a complex task that should only be performed by a qualified mechanic.

  7. Explore Warranty Options: Check to see if your vehicle is still covered under warranty. Even if the factory warranty has expired, you may have an extended warranty or service contract that covers transmission repairs.

  8. Research Potential Recalls: Check the National Highway Traffic Safety Administration (NHTSA) website to see if there are any recalls related to the transmission in your 2017 Jeep Cherokee.

Proactive Steps: How to Keep Your Transmission Happy

Prevention is always better than cure. Here's how you can help prevent transmission problems in your 2017 Jeep Cherokee:

  • Follow the Recommended Maintenance Schedule: Adhere to the manufacturer's recommended maintenance schedule for transmission fluid changes.

  • Use the Correct Transmission Fluid: Always use the type of transmission fluid specified in your owner's manual. Using the wrong fluid can damage the transmission.

  • Avoid Aggressive Driving: Aggressive driving habits, such as rapid acceleration and hard braking, can put extra stress on the transmission.

  • Don't Overload Your Vehicle: Overloading your vehicle can also strain the transmission. Be sure to stay within the vehicle's weight limits.

  • Regular Inspections: Have your transmission inspected regularly by a qualified mechanic.

What About Lawsuits and Settlements?

Due to the widespread complaints about the ZF 9HP48 transmission, there have been multiple lawsuits filed against Jeep and its parent company, Stellantis (formerly Fiat Chrysler Automobiles). Some of these lawsuits have resulted in settlements, offering compensation to affected owners. Keep an eye on class action lawsuit websites and news outlets to stay informed about any ongoing litigation.

Are Some 2017 Cherokee Trims More Affected Than Others?

While the 9-speed transmission was used across various 2017 Jeep Cherokee trims, there doesn't seem to be concrete evidence suggesting that specific trims are significantly more prone to transmission issues than others. The problems appear to be related to the transmission itself, rather than specific configurations of the vehicle. However, factors like driving habits and maintenance history can still play a role in the likelihood of experiencing problems.

Frequently Asked Questions

  • Is the 2017 Jeep Cherokee a reliable car overall? While the transmission issues are a concern, other aspects of the 2017 Cherokee are generally considered reliable. Proper maintenance is key to its overall longevity.
