Known Issues and Common Problems for the 2014-2023 Jeep Cherokee (KL Generation)

The 2018 Jeep Cherokee belongs to the KL generation (2014-2023), and while generally reliable, there are a few issues common to this platform that owners should be aware of:

9-Speed Automatic Transmission Issues: This is perhaps the most widely reported concern. Owners have experienced rough shifts, hesitation, lurching, and sometimes complete transmission failure. Software updates have been released to address some of these issues, but persistent problems might require transmission replacement. Pay close attention to how your transmission shifts.
Uconnect System Glitches: The infotainment system can experience freezing, unresponsiveness, or connectivity issues (Bluetooth, Apple CarPlay/Android Auto). Often, a system reset or software update can resolve these, but in some cases, hardware replacement might be necessary.
Electrical Gremlins: Some owners have reported various electrical issues, including flickering lights, sensor malfunctions, and problems with power accessories. These can be difficult to diagnose and may require professional attention.
Engine Oil Consumption (2.4L Tigershark): The 2.4L engine, particularly in earlier years of this generation, has been known to consume oil. It's crucial to regularly check your oil level between changes, even if you adhere to the recommended intervals. Low oil can cause significant engine damage.
Power Liftgate Malfunctions: The optional power liftgate can sometimes fail to open or close properly, or it may stop working altogether. This is often due to faulty sensors or motors.
Water Leaks (Sunroof/Panoramic Roof): While not widespread, some owners with the optional sunroof or panoramic roof have reported water leaks due to clogged drain tubes or faulty seals. Keep an eye out for dampness or water stains in the cabin.

Being aware of these potential issues can help you identify problems early and prevent further damage.
