RE: 2022 Jeep Grand Cherokee 4Xe (hybrid) This complaint involves a well-known defect and malfunction endemic to the Jeep Wrangler 4Xe with the identical powertrain and software, and a well-documented recall of the Jeep Wrangler, but for some reason, does not yet extend to the Grand Cherokee 4Xe model for identical symptoms and malfunction behavior. The associated recall for the Wrangler is NHTSA campaign number: 22V865000. FCA US, LLC’s number for this recall ZB7, however the Grand Cherokee with the identical powertrain-- has yet to be recalled, however has the same defective issues. This is brand new off-the-showroom 2022 Grand Cherokee 4Xe, and the malfunctioning behavior began within the first 10 days-- at 179 miles (3/4 tank of fuel), with the vehicle going into the FORM (Fuel/Oil Refresh Mode), depriving the vehicle of electric mode or electric assist. The vehicle message stated: "Electric Mode Temporarily Unavailable - Fuel & Oil Refresh in Progress" Other dangerous symptoms and malfunctions associated with the defective/malfunctioning software have occurred: (a) A single instance of a "limp-home" mode (25 mph max on a main thoroughfare), and; (b) several instances of failure of the transmission to shift into a higher gear-- causing the engine to over-rev (over max redline RPM) to maintain a highway speed). At 331 miles, the vehicle was refueled for the first time, and the FORM warning message disappeared with the fresh refuel, however the vehicle hasn't been driven enough to determine of the transmission issues were resolved with the refuel. Nonetheless, the FORM was a malfunction that occurred at 3/4 tank with only 179 miles on the vehicle, and the other malfunctions are presumed to be associated with the primary defect.

Having less than 3K miles in the odometer, the engine started to develop valve train noise that worsens as the engine gets hotter, taken to the dealership to check on the concern plus no start, had the battery replaced after staying 3 weeks in the dealership, supposedly the noise was normal, took it to another dealership as the first one left a few things not fixed, once again i was told the noise was normal, The noise started to get louder as miles were being put on the car, people would ask if the car was a diesel powered one, even the service advisor of the dealership were the car remains asked me if the engine was diesel when she heard the noise. At idling speed the engine is not running smoothly you can hear cylinders misfiring on the exhaust, oil temp remains over 240 when driven, 245 just by pressing the gas to pass a car, oil pressure at idling speed has gone lower as time goes by reaching at times 28 psi. Noise varies when the engine switches in between 8 cyl or 4 cyl mode, in 4 cyl mode the whole car vibrates really bad and loud until you hit the gas to get the engine out of the 4 cyl mode. Service engine light came on once at idling speed when the idling speed became erratic. Engine stalled once. Car in the dealership since Jan 23 2023, was called exactly one month later to pick it up as per they report everything was ok, asked to try another one with the same engine mine has so i could hear the "normal" noise, they had none to check, the shop foreman went on a test ride with me to confirm the issue and then he acknowledged that the noise was weird, so i was asked to leave it, two months already went by and so far no word on the issue, the car has not being further diagnosed by the 'ENGINE EXPERT" will have to go through the lemon law as they just don't say a word or give me options.

This is my Personal Assessment: My vehicle didn't visit the dealer yet and there are no warning lights of any kind and the answer to all the above bullets is NO. Two main issues, 1) Intermittently, when press the gas pedal from idle stop @ traffic light, you will the engine revs but the vehicle either doesn't move or move very slow. In either case, relasing gas and pressing again remediate the situation. This occasional can produce a dangeourous situation and put lives to risk. 2) the second issue is regarding Active Driving Assist System ADAS, also occasionally when the system is all green, steering wheel and all, and ahead of me there is 1/4 of a mile to red traffic light and the road is open for me. I am driving about 50 miles, now approaching the stopped traffic, and suddenly the vehicle start to speed up when it was slowing down for the traffic a moment ago. Something very unusual, I abruptly press the brake to force manual stop. The car then doesn't show this symptom for a few days but occasionally it comes back again.
