The 2014 model has good gas mileage, but some owners have experienced issues
The 2014 Jeep Grand Cherokee has been praised by some owners for its good gas mileage, but others have experienced issues. One owner reported that their 2014 Jeep Grand Cherokee diesel had excellent gas mileage and they were able to drive it for 160,000 miles. However, they also mentioned that they had to perform some common repairs, including replacing the catalytic converter and addressing a catastrophic coolant leak.
Another owner of the 2014 model with the 3.0-L V6 diesel engine reported an issue with the knock sensor, which caused the engine to run strangely and triggered the check engine light. Although the dealership replaced the sensor, the issue recurred after a year. This problem was also experienced by another owner, who had to replace the fuel pump relay.
Other issues reported by owners of the 2014 Jeep Grand Cherokee include problems with the anti-lock brakes, parking brake, sensors, emission-control devices, fuel-injection system, fuel gauge/sender, and fuel pump. Some owners have also mentioned paint issues, such as fading, chalking, peeling, or cracking. In addition, the 2014 model has been recalled multiple times by the NHTSA, with one owner specifically mentioning a recall for a faulty fuel pump relay.
It is worth noting that some owners have expressed concerns about the stability of the 2014 Jeep Grand Cherokee during sudden steering movements. The "moose test" video between the Grand Cherokee and the VW Touareg caused some prospective buyers to choose the latter due to the Grand Cherokee's unstable performance. Additionally, the 2012-2014 V6 models had a unique shifter design that made it unclear which gear was selected, potentially leading to unsafe situations.

The 2016-2019 models have been criticised for their high maintenance and repair costs
The Jeep Grand Cherokee is a powerful vehicle with a range of engine options, including diesel variants. While it is a popular choice for its off-roading capabilities and durability, the 2016-2019 models have received criticism for their high maintenance and repair costs.
Maintenance and repair expenses are a significant aspect of owning any vehicle, and it is essential to consider these costs when purchasing a car. The Jeep Grand Cherokee, particularly the 2016-2019 models, has been associated with higher-than-average maintenance and repair expenses. This reputation has been a point of concern for prospective buyers.
The annual cost to maintain a Jeep Grand Cherokee is estimated to be approximately $1,190, but this can vary depending on the service provider and the specific model year. The estimated cost to maintain and repair these vehicles ranges from $105 to $8,816, with an average of $334. Oil changes are a frequent service requirement, but other common repairs for the Grand Cherokee include issues with the intake manifold, catalytic converter, and fuel tank.
For example, a 2014 Jeep Grand Cherokee owner reported a catastrophic coolant leak around 80,000 to 90,000 miles, requiring repairs. Additionally, the diesel engine in the 2007 model was described as a "beast of a drivetrain," but it was paired with problematic Chrysler electronics, resulting in additional maintenance challenges. These issues contribute to the higher maintenance and repair costs associated with the 2016-2019 models.
To mitigate these expenses, extended warranties are recommended. It is also beneficial to be aware of common issues and perform regular maintenance, such as cleaning the EGR with every oil change and using Liqui Moly through the intake.

The 3.0 CRD diesel model has a metal tank that is prone to rusting
The 3.0 CRD diesel model of the Jeep Grand Cherokee has a metal tank that is prone to rusting. This is due to a design flaw that leaves the tank vulnerable to corrosion from sand, mud, and water splashes from the rear wheels. As a result, owners of this model may eventually experience leaking fuel tanks.
The issue is exacerbated in countries where road salt is used during winter, as the salt can accelerate the rusting process. In such environments, the fuel tank can rust through in just a couple of years. Even changing the tank may not solve the problem, as the new one may also succumb to rust.
One possible solution is to switch to a plastic fuel tank, such as the one used in the 5.7 HEMI model. However, this requires ensuring that all gas is cleaned out to avoid accidentally running gas into the diesel engine. Another option is to repair the rusty metal tank. This involves cleaning the larger rust on the outside with a sandblaster, applying liquid polyester resin, and then pouring a few litres of plastic into the tank to coat the inner layer. However, it is unclear if the plastic used in this method is certified for diesel fuel.
Some owners have also suggested temporarily enlarging the drain holes in the puck of the tank skid to allow for better drainage and potentially slow down the rusting process. Additionally, removing the tank and taking it to a machinist shop to weld on a new section might be an option, but the effectiveness of this solution is uncertain.
Overall, the rusting issue with the 3.0 CRD diesel model's metal tank is a significant problem that has affected many owners, and finding a permanent solution can be challenging.
