TLDR: Until Jeep addresses FORM, CHOC, P0E15, B9A issues permanently, I DO NOT recommend buying ANY 4XE model. Especially in any location that sees cold weather. Lease one if you absolutely must have one.
And my experience? Pretty damn common. Here’s some insight from dealer techs, emphasis mine:
Issue 1: auto-park at every stop.
ASSUMED RESOLVED
Full text warning (Service Hybrid Electric Vehicle System) as well as the corresponding dash light (Red wrench with power symbol). Intermittent, very hard to replicate. Hasn’t reoccurred since software update performed 1/14/22.
Pedal response is off and feels stiffer than usual, the vehicle will kick itself into park at a stop automatically - requiring driver to shift back into drive. It auto parks at Every. Single. Stop. You’ll notice at the start of the video the drive indicator is blinking. It is also blinking on the physical shift lever, and will not go into (proper) drive without first resetting to park.
here’s a short driving clip. Skip to 2:10 for the auto park issue.
Just did some more research and read through the following link. Yikes!
Issue 2: “Service Charging System”
NOT RESOLVED, MANAGEABLE
Error prevents any charging; both L1 and L2 chargers. (Software update performed 1/14, new “charging module” ordered 1/26, installed 1/28, reoccurred 3/21, reoccurred 8/17)
Seems to be an issue between Jeep's vehicle charging port and certain Level 2 charger brands/models. Once triggered, error will prevent recharging at all Level 2 and Level 1 chargers, and must be reset at a dealership. No known solution as of early 2023.
Current workaround - if this error fires off, immediately note the station the vehicle is plugged into, and try to remember the one previous before that. Once of those stations likely tripped the error. Avoid those stations and note the model/manufacturer. Until further notice, avoid any stations that match that model/manufacturer.
Issue 3: “Battery Cooling System Failure , Pump B Over Speed”
RESOLVED
New set of problems.
A battery coolant system failure, and an out of tolerance secondary pump. (P1DBA-00, P2E46-00)
Issue due to low hybrid coolant in hybrid cooling system. Additional coolant added to reservoir. System was tested for leaks, none found, and codes were cleared.
Issue 4: “Check Engine Light, EVAP Leak”
RESOLVED
New Issue. Check engine light came on again. Vehicle had been undergoing several tests to confirm a leak in the EVAP system. One week in the repair shop, and a star case ticket later… the tech determined it was caused by a loose fuel cap. (What?)
Issue 5: “Electric Mode Unavailable Cabin Cooling or Heating”, P0E15 LOCKED PERMANENT, LOCKED FORM
PROBABLY NOT RESOLVED. (FORM cleared after 80F weather)
New Issue. “Electric Mode Unavailable, Cabin Cooling or Heating” error immediately after an oil change. Appears to kick in within first half mile of all electric driving. Does not go away when A/C and heat set to OFF.
Further evaluation of Cabin Cooling or Heating (CHOC) issue is not possible, as the vehicle has entered into the “normal” Fuel and Oil Refresh Mode (FORM) for the wintertime. Will revisit issue in spring time.
Using an off the shelf OBDII scanner, was able to confirm "Locked Permanent" status of HV Coolant Heater. This can be confirmed by the lack of any kw usage by the climate system. Will need to have the dealership look at this again at next vehicle drop-off.
Dealership confirmed the hybrid coolant heater is indeed bad (P0E-15), and will require replacement. After 22 days, dealership informs me that the replacement hybrid hv coolant heater is not pairing with the vehicle. STAR case was opened, and any additional hv coolant heaters would need to be ordered by the STAR team.
Customer Retention Team is now involved. (Way too late. Second time vehicle has been out of service for multiple weeks, for clearly a warranty issue.) Attempting to expedite part delivery and install.
There are two separate hybrid battery heaters on the same 4XE system. In my situation, both required replacement. (Part 68400740AD and 68443445AC). One of these two parts had an initial ETA of 3/10.
I’m fed up. Stuck in fuel or oil refresh mode (FORM) again. Weather has been consistently around 50F. Oil life has an indicated 98% remaining. Obviously been refueling as I’m driving. Just get a gas Jeep or buy something else.
FORM finally cleared. Weather above 80F for next five days.
Getting stuck in Fuel or Oil Refresh Mode (commonly abbreviated as FORM) is a common issue. Jeep views it as normal operating behavior. Officially, their guidance is as follows:
Other plug-in hybrids may see decrease in usable EV range in winter, but as of 2023, I’m not aware of any other manufacturer with a class action lawsuit regarding it’s winter behavior:

Issue 6: Death Wobble
RESOLVED
Weak steering damper. Vehicle has developed the fabled “death wobble”, which somehow eluded my super reliable JK. When driving at speeds over 60mph, any bump or change in road condition causes a notable vibration throughout cabin, lasting anywhere from five to fifteen seconds.
Steering damper was replaced. This has resolved the death wobble issue, but will continue to keep an eye on it.
Issue 7: Rear LED moisture
MINOR, PART ARRIVED - AWAITING INSTALLATION
Update 7/23/23: New defect, minor. Sealant of LED housing on rear left has failed. Obvious moisture intrusion and retention. Will ask nearest trusted dealership to evaluate on next oil change.
Udate 8/16/23: Tech confirmed issue, and has ordered a replacement. No ETA due to current strike situation.
Update 12/2/23: Part arrived. Awaiting FCA approved Enterprise loaner.
Issue 8: Front Axle Noise, Replacement
MINOR, PART ARRIVED - AWAITING INSTALLATION
New issue. Jeep developed a notable clicking noise when turning at low speeds. Previously believed to be a ball joint or tie rod issue, tech now believe it’s related to the front axle assembly. New part ordered, no ETA due to current strike situation.
Update 12/2/23: Part arrived. Awaiting FCA approved Enterprise loaner.
Issue 9: Recall B9A (NHTSA 23V-787)
NOT RESOLVED, TBD
Are you freaking kidding me?
Per latest update on Mopar.com, my VIN is on the list of affected models for recall B9A. The guidance remains unchanged:
Customers are advised to refrain from recharging these vehicles and not to park them inside of buildings or structures, or near other vehicles until the vehicle has the final repair completed.
Issue 10: Recall 04B (NHTSA 27V-111)
NOT RESOLVED, TBD
The Jeep has been effectively mothballed for last few months. Maybe a good thing, since “Suspect vehicles may not have a functional defrosting and defogging system under certain conditions.” We had a few small snowstorms recently. Would have hated not having a working defroster. The GX is doing well. Logged 1200 miles on it so far, no complaints.
Updates:
2021
Update 9/7: RRTs 21-122, 21-123, 21-124, 21-126, and 21-127 applied. Recall Y-46 performed on 9/8. Part was inspected, replacement was deemed not necessary.
Update 9/15: Issue is still ongoing, recent RRTs 21-122, 21-123, 21-124, 21-126, and 21-127 did not resolve the issue. Intermittent and infrequent.
Update 9/19: First bit of night driving since the last repair. Dome light programming is not behaving as expected. Double checked to make sure rolling switches were in correct position (max setting on left, near max on right), noticed dome lights no longer illuminate when doors are open. Dealership suspects driver’s door wiring, but needs more time to complete diagnostics. Still have the auto park issue.
Update 11/22: Issue still not resolved. Haven’t been able to secure a loaner to allow vehicle to sit long term at dealership. Dealership doesn’t have loaners. Part of issue is local market, Jeep has authorized $55 for a loaner, but that is not enough in this area (DC/Baltimore). Holiday travel season - I’m effectively out of town until New Years. Will revisit after that.
Update 12/21: New issue. “Service Charging System” prevents charging at any charging station. Will display two lights at end of dash mounted light bar, red light at charger port, and charger symbol in driver’s cluster. Tested and confirmed issue with both level 1 and level 2 chargers.
2022
Update 1/14: Software update from dealership has allowed vehicle to use chargers again. There does not appear to be numeric code for this update. “Fuel and Oil refresh” engaged, and may be stuck. Intermittent “auto-park” issue has not reoccurred. Software update and verification required less than a half day of work.
Update 1/16: Nope. Charging problem has returned after two days. Frustrating. Vehicle is just not reliable. Back to the dealership we go…
Update 1/26: Got a status update from nearest trusted dealer. Their EV specialist confirmed the same error codes showed a fault with the charging system. Since software was previously upgraded, next step is to replace the onboard “charging module”. Module is expected to arrive on Friday at the earliest, and they will give me another update once it arrives.
Update 1/28: Dealership has completed installation of new charging module. Charging issue still persists. Dealership is now opening a case with FCA/Stellantis.
Update 2/9: Got vehicle back from dealership. Charging issue appears to be resolved. Two items related to charging addressed: (1) IDCM “charging module” replaced. (2) Pin 42 on connector 2 replaced. Vehicle is still in fuel and oil refresh mode - will need to see if this clears on next fill up.
Update 3/21: Charging issue is back again. One off - hasn’t reoccurred since
Update 6/21: New set of problems.
A battery coolant system failure, and an out of tolerance secondary pump. (P1DBA-00, P2E46-00)
Update 6/28: Issue due to low hybrid coolant in hybrid cooling system. Additional coolant added to reservoir. System was tested for leaks, none found, and codes were cleared.
Update 8/16: New Issue. Check engine light came on again. Vehicle had been undergoing several tests to confirm a leak in the EVAP system. One week in the repair shop, and a star case ticket later… the tech determined it was caused by a loose fuel cap. (What?)
Update 8/17: “Service Charging System” error has returned.
Update 11/7: New Issue. “Electric Mode Unavailable, Cabin Cooling or Heating” error immediately after an oil change. Appears to kick in within first half mile of all electric driving. Does not go away when A/C and heat set to OFF. Attached a copy of S2208000027. Highly recommend sharing this with your dealership / service tech.
Update 11/16: Further evaluation of Cabin Cooling or Heating (CHOC) issue is not possible, as the vehicle has entered into the “normal” Fuel and Oil Refresh Mode (FORM) for the wintertime. Because vehicle is now stuck in winter FORM (with a recent oil change two weeks ago), there is no record in vehicle computer of the CHOC issue, and thus, cannot be further evaluated. Will revisit in the springtime. New Issue: Weak steering damper. Vehicle has developed the fabled “death wobble”, which somehow eluded my super reliable JK. When driving at speeds over 60mph, any bump or change in road condition causes a notable vibration throughout cabin, lasting anywhere from five to fifteen seconds.
Update 12/29: Using an off the shelf OBDII scanner, was able to confirm "Locked Permanent" status of HV Coolant Heater. This can be confirmed by the lack of any kw usage by the climate system. Will need to have the dealership look at this again at next vehicle drop-off. Still waiting on the steering damper. original ETA was 11/30, still have not gotten part.
2023
Update 1/11: Steering damper was replaced. This has resolved the death wobble issue, but will continue to keep an eye on it.
Update 1/26: Got a call from trusted dealership. They have confirmed the hybrid coolant heater is indeed bad, and will require replacement. Part ETA is early February.
Update 2/17: Day 22 of rental. Trusted dealership informs me that the replacement hybrid hv coolant heater is not pairing with the vehicle. STAR case is opened, and any additional hv coolant heaters would need to be ordered by the STAR team.
Update 2/28: Day 33 of rental.
Customer Retention Team is now involved. (Way too late. Second time vehicle has been out of service for multiple weeks, for clearly a warranty issue) Attempting to expedite part delivery and install.

Update 4/5: FORM finally cleared. Weather will be above 80F for next five days.
Update 7/23: New defect, minor. Sealant of LED housing on rear left has failed. Obvious moisture intrusion and retention.
Update 8/16: New defect, minor. Jeep developed a notable clicking noise when turning at low speeds. Previously believed to be a ball joint or tie rod issue, tech now believe it’s related to the front axle assembly. New part ordered, no ETA due to current strike situation.
Update 12/2: Are you freaking kidding me? Per latest update on Mopar.com, my VIN is on the list of affected models for recall B9A. Replacement axle, rear taillight have both arrived at nearest trusted dealership, and are awaiting availability of a FCA loaner via Enterprise. Once that’s arranged, I’ll have the Jeep flashed to see if I’m one of the bad batteries.
Update 12/19: Purchased replacement for the Jeep. Jeep is on a pitch count and effectively mothballed for the rest of the season. (The replacement is a Lexus GX 460. 2023 is the last model year.)
2024
Update 2/23: The Jeep has been effectively mothballed for last few months. Maybe a good thing, since “Suspect vehicles may not have a functional defrosting and defogging system under certain conditions.” We had a few small snowstorms recently. Would have hated not having a working defroster. The GX is doing well. Logged 1200 miles on it so far, no complaints.
Update 2/27: B9A recall is now available. Check your nearest trusted dealership for details. Process is extensive - here is a sample of the documentation.
Update 4/3: Said Goodbye. Jeep was surrendered under lemon law.
And my experience? Pretty damn common. Here’s some insight from dealer techs, emphasis mine:
As a dealer tech the 4XE is by far the most unreliable wrangler we have on the market, disregarding the new fire recall completely. Frequent visits for recalls/CELs/parts taking 45+ days to come in are very common.
Unless you *have* to have a 4XE, I'd strongly recommend just getting a normal 2.0/3.6/392. The 4XE is super fun when it works, but a lot of the kinks still haven't been worked out.
They're still using this same part in the 4xe and grand cherokee 4xe and it's still failing. I've replaced enough in the pacifica alone to stack them to the roof twice over. One of our 4xe techs had to replace one in a new grand cherokee 4xe this week with only 4k miles on it. They're using known defective parts on the production line as we speak. Watching labor times continuouesly drop on a frankly shitty job is a lovely experience.
Blame stellantis for dropping labor times over and over again for your lack of technician willingness to work on them. These things have a 10 year/150k mile EV warranty so it's a lot of warranty work.

Getting stuck in Fuel or Oil Refresh Mode (commonly abbreviated as FORM) is a common issue. Jeep views it as normal operating behavior. Officially, their guidance is as follows:
For the last three years, I have not been able to clear FORM in the winter months. This is consistent with the final paragraph of their guidance. We have relatively mild winters in my region, but YMMV.How can I get Electric mode back?
The use case which leads to this level of dilution can vary, but the path to resolution is always the same:
- Start the engine and allow engine oil to reach normal operating temperature. 169°F (76°C) is the minimum, but normal operating temperature is above 194°F (90°C). Elevated speed and load will warm the engine oil most quickly.
- Continue running the engine until FORM is no longer shown in the Message Center of the instrument cluster. Depending on the dilution level, oil temperature and outside temp, this can take from 20 minutes to 2.5 hours.
- In case the above steps are not possible, change the engine oil and reset the oil life indicator.
- Never reset the oil life indicator without changing the engine oil.
It's possible that some use cases lead to a lot of dilution and not enough evaporation to compensate. In this case FORM will return as long as the weather remains cold. We have high confidence that these frustrations will be resolved when the weather becomes warmer.
Other plug-in hybrids may see decrease in usable EV range in winter, but as of 2023, I’m not aware of any other manufacturer with a class action lawsuit regarding it’s winter behavior:
