They definitely know about it.
I have tried to speak with someone at Stellentis but they will not take calls. They say you cannot talk with anyone related to manufacturing the vehicle about this issue. They refer you back to the Jeep dealer. They flat out sai they sell it to them, then it is their issue. Obviously, that is not the case, but easier to get you off of the phone and hope you will not file suit or talk about it enough that they have to fix the problem. Essentially, someone with Stellentis believes that it should now be acceptable to only drive your car using the electric mode (the major reason you purchased your car) in 'warm enough weather'. That is a major thing to either not disclose when selling, or to not fix after the problem is realized by a manufacturer.
Here is the known problem:
Case Number: S2208000020 REV. A
Release Date: August 2022
Symptom/Vehicle Issue: Electric Mode Temporarily Unavailable, Cluster Message Displayed Vehicle in Fuel Oil Refresh Mode (FORM)
Customer Complaint/Technician Observation: Owner complains the vehicle will not go into Electric Vehicle (EV) mode. Technician observed no Diagnostic Trouble Codes (DTC’s) and the message for FORM during the initial startup for 5 seconds and the vehicle is not entering EV Mode during drive test cycles.
Discussion:
Operator Choices that can inhibit Electric Mode - and what to do about it
Transmission in Manual Shift mode - Shift to Drive to use Electric mode.
Heavily depressed accelerator pedal position, requesting high power demand - Beyond the limits of the electric drivetrain, will cause engine to run, enabling the powertrain to produce its full combined power available in Hybrid mode.
Sustained high speed operation in Electric mode - Using the engine is more efficient for high speeds than Electric drive.
Transfer case and drive mode selection - eSave mode almost always runs the engine. Hybrid mode, in 4WD Low, will also run the engine.
Electric range is depleted - You need to recharge to enjoy Electric mode, or you can continue normally in Hybrid.
Hood open (or a hood switch fault) - This is to prevent unexpected engine starts with the hood open.
Thermal Protection that can inhibit Electric Mode - and why
Engine, transmission, or engine starting belt too cold - Some systems require warm-up to function properly if the outside temperature is below 32°F (15°F in Electric drive mode).
Electric cabin heating capacity limits (or electric cabin heater fault) - Unlike Battery Electric Vehicles (BEV's), the PHEV Wrangler can warm the cabin more efficiently with engine heat when operating below 15°F outside temperature.
HV battery, motors, or contactors over temperature - This is a temporary hardware protection feature. Vehicle performance will resume once protection is no longer required. If the vehicle performance is accompanied with a Malfunction Indicator Lamp (MIL) .
Component Protection that can inhibit Electric Mode - and what to do about it
HV battery undervoltage - Sustained EV operation at high speed, especially with aftermarket wheels and tires, can induce this.
Other electric propulsion system faults indicated by a MIL service required. Fuel And Oil Refresh Mode
FUEL AND OIL REFRESH MODE Since it is possible to operate this vehicle for extended periods without running the gas engine, the fuel within the tank can become stale and/or the engine oil’s lubricating properties can be reduced as the vehicle’s engine is not operating under its normal engine operating temperatures.
To prevent engine and/or fuel system damage due to stale fuel, or lubrication, this vehicle is equipped with a Fuel Oil Refresh Mode (FORM). The vehicle will automatically enter the Fuel Oil Refresh Mode to minimize these conditions. When operating in this mode, the gas engine must operate at its normal operating temperatures, no EV propulsion (electric only operation
is inhibited). A reminder message will be displayed within the cluster during initial start-up whenever
Fuel AND Oil Refresh Mode is active. The vehicle will automatically exit the Fuel Oil Refresh Mode when conditions have been satisfied for adequate run time of up to 2 hours.
If the vehicle enters Fuel Oil Refresh Mode, due to stale fuel, the engine will run during this mode, no EV operation until the
low fuel level warning is achieved. If desired, it is possible to exit the
Fuel Only Refresh Mode by adding a minimum of four gallons of new fuel to the vehicle.
NOTE: If the vehicle enters Fuel and Oil Refresh Mode to maintain engine lubrication, adding fuel
will not exit the mode sooner. If the vehicle enters Fuel Oil Refresh Mode for lubrication requirements, the engine must operate at maximum operating temperatures until accumulated engine run times of 20 minutes to 2 hours. This can be best achieved by engine running at highway speeds above 50 mph for extended periods. If the vehicle is shut down without the proper accumulated engine only run time, the engine will run without entering EV mode on subsequent trips.
NOTE: Frequent short trips without (max engine operating temperatures) usually triggers the lubrication-based oil refresh mode. If the engine run time is not met in-between the oil change intervals, changing the engine oil, and resetting the service reminder is the recommended option.
DO NOT RESET THE OIL INDICATOR WITHOUT CHANGING THE OIL FOR THIS CONDITION.
