The 2016 Jeep Grand Cherokee represents a significant moment for the iconic SUV, blending classic off-road capability with modern luxury and technology. While generally regarded as a reliable and well-built vehicle, potential buyers and current owners should be aware of specific 2016 Jeep Grand Cherokee issues that emerged within the model year. Understanding these common problems, ranging from minor infotainment glitches to more significant mechanical concerns, is essential for making an informed purchasing decision or addressing existing nagging faults.
Common Electrical and Infotainment Glitches
One of the most frequently reported 2016 Jeep Grand Cherokee issues centers around the vehicle's infotainment system and overall electrical stability. Owners have experienced intermittent malfunctions with the Uconnect system, including unresponsive touchscreens, freezing, and complete system crashes. These issues can disrupt navigation, audio playback, and access to critical vehicle settings, leading to frustration and potential safety concerns while driving.
Beyond the main screen, electrical gremlins often manifest in other areas. A startling number of reports cite dead battery incidents, where the vehicle fails to start due to a drained battery. This is frequently linked to a parasitic drain caused by a faulty control module or a software issue that prevents the vehicle from entering a true sleep mode when parked. Additionally, issues with the power liftgate, where the tailgate fails to open or close automatically, point to deeper electrical or wiring harness problems inherent to this year's model.
Mechanical Concerns: Transmissions and Cooling
Transmission Hesitation and Failure
The 8-speed automatic transmission, paired with the available 3.6-liter Pentastar V6, is a core component of the Grand Cherokee's performance. However, a notable subset of 2016 models has suffered from transmission hesitation, where there is a noticeable delay or lurch when shifting between gears, particularly when pulling away from a stop. In more severe cases, this can escalate into complete transmission failure, characterized by the vehicle being stuck in a single gear or slipping between them, which requires immediate and costly repair.
Overheating and Coolant System Leaks
Maintaining optimal engine temperature is critical, and some 2016 Grand Cherokees have struggled with overheating issues. These problems are often traced to the internal plastic components of the timing cover, which can crack over time. This crack allows coolant to seep into the engine's oil passages or out into the environment, leading to a significant loss of coolant and a dramatic rise in engine temperature. Driving an engine with low coolant can cause catastrophic damage, making this a critical issue to address immediately if you notice a rising temperature gauge or visible fluid leaks beneath the vehicle.
When inspecting a used 2016 Grand Cherokee, always check the coolant reservoir for signs of oil contamination, which indicates a internal leak, and look for puddles of green or orange fluid underneath the vehicle. Ignoring these signs can lead to engine warping or failure, turning a simple repair into a total engine replacement.
Interior and Component Wear
Even in a relatively new model year, certain interior components can show signs of premature wear. The sunroof mechanism is a common culprit, with some owners reporting excessive noise, sticking, or even complete failure to open or close. This issue stems from the complex motor and track assembly, which can become clogged with debris or suffer from motor fatigue over time.
Another area of concern is the front suspension, specifically the lower control arm bushing. In some instances, the rubber bushing can wear out or tear prematurely, leading to a distinct clunking or popping sound over uneven road surfaces. This not only creates an unpleasant noise but can also negatively impact the vehicle's handling and tire wear, compromising the safe and smooth ride the Grand Cherokee is known for.
