2021 JEEP WRANGLER- Burbank, CA
Glendale Dodge (CA) is actively using Federal Fire Risk Recall 68C to fraudulently conceal a separate, critical High-Voltage hardware failure on my 2021 Jeep Wrangler 4xe. Upon intake, my vehicle’s internal VIP diagnostic scan showed an active P0E15 code (Electric Coolant Heater Failure). Per Stellantis Technical Service Bulletins, this code indicates a severe failure requiring a physical hardware replacement to ensure the high-voltage system operates safely. To avoid performing this costly warranty repair, the dealership deliberately falsified the diagnosis on Final Invoice #31349. Under Line C (Customer States Check Engine Light is On), the dealership officially recorded the cause and correction as: 'DUE TO RECALL MODULE UPDATES AND BAD BATTERY.' This is an affirmatively false written diagnosis. A dead 12V battery and a recall software update do not cause, nor do they resolve, a P0E15 High-Voltage Electric Coolant Heater failure. The dealership lied on the legal invoice to scrub the hardware defect from the record. They then applied the 68C software patch as a smokescreen, falsified the 'Date Out' to 12/26/2025 to prematurely close the federal recall ticket, and attempted to return a vehicle that remains mechanically compromised and unsafe. This is intentional warranty fraud masking a high-voltage system failure. Stellantis and its authorized repair facility are refusing to properly remedy the vehicle. The vehicle is currently held at the dealership pending an active fraud investigation by the California Bureau of Automotive Repair (Case #6596-WS4PV6).

2021 JEEP WRANGLER- Oceanport, NJ
Vehicle stalled out. Then would not start. Daughter was stuck for 30 minutes until it finally turned over took it into dealership. Was told it’s the fuel pump. My issue is that now. These fuel pumps are back ordered indefinitely found out because all of the fuel pumps are going bad on the jeeps. Now we have a faulty part that the dealership is aware of that you cannot get replaced due to so many of them needing to be replaced, which tells me they know this part is faulty was told they’re not even sure if or when they would be able to get the part now you have all these people driving jeeps that can stall out on the road and get into a terrible accident. My daughter is [XXX] and this is not acceptable. She has a faulty car part and Jeep has no parts to replace this faulty part.

2021 JEEP WRANGLER- San Diego, CA
I own a 2021 Jeep Wrangler Rubicon 392 with the 6.4L engine (VIN: [XXX] ). The vehicle has a dangerous condition where the engine stalls unexpectedly when the fuel level is approximately 1/4 tank or lower and the vehicle is traveling downhill. When the vehicle is positioned on a decline or downhill slope, the engine suddenly shuts off without warning. This appears to be fuel starvation on decline when the fuel level is below approximately 1/4 tank, resulting in engine stall and loss of power steering and braking assist after stall. This has occurred multiple times and creates a significant risk of crash due to the sudden loss of engine power and reduced steering and braking assistance while the vehicle is in motion. The issue is particularly concerning when descending hills or driving on angled terrain. The vehicle was taken to an authorized dealership (Carvana Jeep San Diego) where technicians determined the likely cause is a defective fuel pump module associated with the Wrangler Rubicon 392 6.4L fuel pump module. However, the dealership informed me the replacement fuel pump module is currently on national backorder from the manufacturer (Stellantis/Jeep). They stated there is no confirmed availability date and that many vehicles may be waiting for the same component. My vehicle has been awaiting repair for approximately four months due to the unavailable fuel pump module. Because the vehicle can stall unexpectedly while traveling downhill, this defect presents an ongoing safety hazard and potential risk of crash. This complaint is being submitted so the issue can be evaluated as a potential safety defect involving fuel delivery failure, fuel pump module malfunction, and engine stall under low fuel conditions in the Jeep Wrangler Rubicon 392.

2021 JEEP WRANGLER- Landrum, SC
While driving higher speeds (45 mph+) I have had my vehicle start shaking very violently which results in me having to slam on my breaks to gain control of my vehicle. When this happens I have been traveling on the highway or interstate which puts other drivers at risk due to me unexpectedly having to come to a halt to gain control of my vehicle. I have taken my vehicle to the mechanic multiple times (dealership twice and local mechanic twice) and I have had everything replaced on the front end that could cause this and it is still happening. Steering dampener has been replaced twice in a year. Mechanic seems to believe that there is a design flaw in the vehicle that is causing it at this point. There is no warning message or anything that gives me any warning. I am scared to drive my vehicle on the highway or interstate.

2021 JEEP WRANGLER- Williamstown, NJ
My 2021 Jeep Wrangler Rubicon (3.6L eTorque, automatic transmission) has experienced recurring drivetrain instability beginning at approximately 2,000 miles while under factory warranty. The vehicle intermittently exhibits a high-RPM flare during acceleration, where the engine speed increases without a commensurate increase in vehicle acceleration. The transmission then abruptly engages, causing sudden jerking. At low speeds (approximately 10–5 mph), the vehicle shudders and harshly downshifts, creating a sudden grabbing sensation. Engine RPMs fluctuate during deceleration as if the transmission cannot smoothly match engine speed. Braking feels inconsistent, and at times it feels as though the vehicle is accelerating or resisting braking input before abruptly slowing. The vehicle has felt as though it would stall at low speeds and has stalled intermittently. Additionally, the forward collision warning / automatic emergency braking system has activated without an obstacle present. There have also been intermittent instances of loss of power steering assist. The engine has developed a ticking noise and a high-pitched ringing/whining sound from the engine area during operation. In January 2026, the transmission catastrophically failed and required replacement of the transmission, torque converter, cooler, and control module. The vehicle was out of service for over 24 days. Following installation of a Mopar remanufactured transmission and torque converter, the same symptoms have recurred, including RPM flare, delayed shifting, shuddering, harsh downshifts, unstable deceleration, and abnormal engine noises. These conditions present a safety concern due to loss of expected acceleration, unpredictable torque engagement, unintended braking activation, intermittent power steering loss, stalling behavior, and drivetrain instability. The vehicle is currently under further diagnostic evaluation. I have multiple documents, but the file is too large to upload

2021 JEEP WRANGLER- Rochester, NY
At any speed above 50 mph the steering violently shakes if I hit bridge seams, cracks, or potholes. At speeds about 60 it's significantly worse and around 40 it still wobbles for ~3/4 of a second

2021 JEEP WRANGLER- New York, NY
Car partially charged and when driving feels like it’s going to stall out. Seems like whatever update Stellantis did to hide the 4xe issues is impacting my ability to safely get around

2021 JEEP WRANGLER- Lancaster, WI
This is a plug in hybrid vehicle. The (ECH) electric coolant heater is prone to failure. This failure can lead to loss of power and might cause the hybrid battery pack to not regulate its temperature leading to a fire. This is a high failure rate with some saying it has failed more than once. Jeep 4xe Fans on Facebook has been doing some tracking of numbers and shows a 50% failure rate with some failing after being replaced. This failure is not being addressed by Jeep.

2021 JEEP WRANGLER- Chicago, IL
The vehicle manufacturer is aware of the problem with my Jeep, yet they have not taken meaningful action to resolve it. At this point, the local dealer continues to charge diagnostic and repair fees only, focusing on steering and wheel inspections, while the death wobble persists. During the warranty period, I submitted video evidence showing the vehicle shaking severely. After reviewing the video, the dealer immediately installed a steering damper at no cost. However, that solution was only temporary. The same dangerous shaking returned and has continued to repeat. Now it appears that the manufacturer is declining to take action because my warranty may have expired. However, I have documented proof that they acknowledged the defect during the warranty period and performed repairs related to it. I have records of those warranty repairs. This is not a minor vibration. This is a severe and potentially fatal instability that occurs at highway speeds. While driving, the vehicle will suddenly begin violent front to back shaking with loud noises, forcing me to rapidly slow down or nearly stop to regain control. These dangerous events happen far too often. For example, last month I drove a round trip between Chicago and North Carolina and experienced more than forty instances of shaking, ranging from moderate to severe. The vibrations are intense enough that other vehicles on the road can clearly see and witness what is happening.
