The 2017 Jeep Grand Cherokee represents a peak in the model's history, blending refined luxury with serious off-road capability. Despite its generally solid reputation, owners and potential buyers often encounter specific issues that define the ownership experience for this particular year. Understanding these common problems with Jeep Grand Cherokee 2017 models is essential for making an informed purchase decision or addressing existing concerns proactively.
Electrical System Quirks and Software Glitches
One of the most frequently reported issues centers around the sophisticated electronics packed into the 2017 Grand Cherokee. The Uconnect infotainment system, while feature-rich, can be prone to glitches, slow response times, and occasional crashes. Owners often complain about the radio resetting itself, Bluetooth connectivity dropping unexpectedly, or the navigation system freezing. Furthermore, the complex network of sensors and cameras can sometimes trigger false warning lights, such as the stability control or 4WD indicator, due to software errors rather than mechanical faults.
Key Fob and Remote Start Challenges
The keyless entry system presents another electrical pain point. The key fob battery can die unexpectedly, and more significantly, some units suffer from signal interference that prevents the doors from unlocking reliably. Remote start functionality, a popular feature in the colder months, is also susceptible to failure, often requiring the physical key to be inserted into the ignition as a workaround. These minor annoyances disrupt the seamless convenience the vehicle aims to provide.
Mechanical Concerns Under the Hood
While the 3.6-liter Pentastar V6 engine is generally reliable, it is not without its specific quirks. Some owners have reported a ticking noise emanating from the engine bay, often attributed to the hydraulic lifters or the timing chain tensioner. Although typically not catastrophic, this sound can be concerning and persistent. Transmission issues also surface in this model year, particularly with the 8-speed automatic, including harsh shifting into first gear and, in rarer cases, premature wear requiring reprogramming or replacement.
Suspension, Steering, and the Air Suspension Flaw
The Grand Cherokee’s ride quality is largely dictated by its suspension setup, and the 2017 model is no exception. Owners frequently report a choppy ride over uneven pavement, with the vehicle feeling loose or unsettled during aggressive cornering. This is often linked to worn ball joints, control arm bushings, or struts. For models equipped with the optional air suspension, a critical design flaw emerges: the air springs are prone to developing leaks. A failing air spring causes the vehicle to sit severely uneven, compressing one corner and putting immense stress on the compressor and air lines.
