When evaluating the long-term ownership experience of a 2017 Jeep Grand Cherokee, potential buyers look beyond the initial purchase price and glossy marketing photos. Reliability represents the intersection of engineering durability and day-to-day usability, determining whether the vehicle remains a dependable companion or becomes a financial sink. For the 2017 model year, this mid-to-full-size SUV generally presents a mixed but largely positive reliability profile, particularly when compared to segment rivals. Understanding the specific strengths and weaknesses of this year helps owners maximize their investment and ensures the vehicle lives up to its adventurous promise.
Overview of the 2017 Model Year
The 2017 Jeep Grand Cherokee marked a significant point in the generation's lifecycle, sitting comfortably in the middle of a model run that began in late 2014. By this year, the platform had been thoroughly debugged, meaning most of the early teething issues had been addressed by the factory. The lineup offered a range of powertrains, from the efficient 3.6-liter Pentastar V6 to the high-performance 6.4-liter HEMI V8 and the available 3.0-liter EcoDiesel, giving buyers flexibility in balancing power, efficiency, and reliability expectations. This variety means reliability discussions must consider the specific engine and drivetrain configuration.
Drivetrain and Powertrain Reliability
The heart of the Grand Cherokee's reliability story lies in its proven powertrain options. The 3.6-liter V6 and the 5.7-liter HEMI V8 represent Jeep's core philosophy, utilizing technology that has been refined over decades in other Chrysler products. These engines are known for their robustness when maintained properly, often exceeding 200,000 miles with basic care. The 8-speed automatic transmission paired with these units is generally considered a strong point, offering smooth shifts and proven durability. Conversely, the diesel option, while efficient and torquey, introduces more complex technology that can be a concern for some reliability-focused buyers.
3.6L Pentastar V6: Excellent parts availability and widespread mechanic familiarity.
5.7L HEMI V8: Proven technology with strong towing capacity and longevity.
3.0L EcoDiesel: Efficient but more complex, with potential for higher repair costs if issues arise.
8-Speed TorqueFlite Transmission: Generally reliable, but watch for fluid maintenance issues.
No vehicle is perfect, and the 2017 Grand Cherokee has specific trouble spots that owners should monitor. One of the more common concerns involves the rear control arm bushings and sway bar links, which can wear out prematurely, leading to clunking noises over rough terrain. Electrical gremlins, while not as prevalent as in some modern vehicles, can manifest in infotainment system glitches or sensor errors. Additionally, the air suspension systems found on higher trims, while a luxury feature, are a known potential failure point that can be expensive to repair when they eventually leak.
