About the Patriot
Jeep’s entrant into the compact crossover SUV market, the Patriot, first made its debut in 2006. Unfortunately, Jeep may have been too early in terms of the class’ popularity as the model was late discontinued in 2017.
During its time on the market, only a single generation was released. Like its corporate cousin, the Dodge Caliber, it was built on the GS platform.
As a relatively older compact crossover, it faced competition from the Subaru Forester, Hyundai Santa Fe, and Ford Escape. It was also considered to play a stylistic inspiration for the Jeep Renegade.
In its decade on the market, owners reported that P0456 was the most common code to be logged. This code indicates that there is a small leak in the EVAP system.
American vehicles are very prone to this issue and the cause is mainly a faulty or loose fuel cap. However, the Patriot is also susceptible to EVAP module failures. This can be somewhat of a more expensive fix. Other reported causes include faulty components in the system.
Another issue that Patriot owners have had to deal with is P0420, which indicates that the catalytic converter is likely failing.
This can be a result of old converters being in need of replacement, as well as exhaust leaks upstream of the converter. Some owners have also noted that their oxygen sensors were at fault. The upstream oxygen sensor in particular needs to be checked.
Fault code P0335 is a crankshaft position sensor code that is reported by owners fairly often.
This code indicates that the CKP sensor likely needs to be replaced. It is also a good idea for owners to check the sensor circuit for electrical faults.
