About the Commander
The Commander first made its debut in 2005. The first generation continued until 2010 when the model was put on an eight-year hiatus. The release of a second generation came in 2018 but was later discontinued in 2022.
Like with many other Jeep models, the Commander is usually compared to other models in the lineup. In this case, the Grand Cherokee is the most similar competition.
Competition from outside of the Jeep family typically came from the Toyota Highlander, Toyota FJ Cruiser, and Ford Edge.
One of the most common issues that the Commander has suffered from is P0507, which indicates that the engine is idling at a higher RPM than expected.
This code is commonly caused by an intake leak in the engine, causing the engine to cycle faster than intended. Of course, if the engine is not actually idling any faster than usual there could be a control module issue at play.
Fault code P0700 is another fairly commonly reported problem for the model according to owners. This code indicates that there is a malfunction in the transmission control system.
In most cases, this code requires a more advanced code scanner to pick up additional issues from the transmission. Fixing it usually requires addressing any other transmission codes that have been logged.
Another problem that has been reported commonly is P0300, which is logged when multiple random misfires have been detected.
Similar to the previous code, fixing this issue typically requires owners to first address any other codes that could influence the combustion process. However, installing new ignition coil packs is one of the best things to try first.
