Known Problems

There have been numerous complaints of early transmission failure, even with with normal servicing. Issues start with a whining noise, overheat warnings, and an inability to accelerate. The most common solution is replacement of the transmission. Late 2014 model year Patriots changed to a non-CVT transmission.

Water leaks may be noted from the front and/or rear roof area. Our technicians recommend to inspect the roof ditch and sunroof - Check all grommets and plugs, reseal roof seams, and replace the sunroof drain tubes if necessary.

Vehicles equipped with manual transmissions may become difficult to shift. The repair may involve replacing the 3rd/4th/5ht & reverse gear synchronizer rings as a set.

A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.

An engine overheating condition may develop due to a coolant flow issue. Our technicians tell us that debris may block the cylinder head coolant port at the primary thermostat housing. Removing the debris should correct this concern.

Our technicians tell us the "MyGig" radio may become damaged when disconnecting and reconnecting the battery due to electrical spikes. Removal of the 30amp radio fuse is recommended before disconnecting the battery on these vehicles.

On vehicles with a Boston Acoustics Audio System, the display may not return to the equalizer settings after using the hands free/voice recognition mode. Our technicians tell us an amplifier software upgrade is available to correct this concern.
