2021 Jeep Wrangler: engine stalls while driving

Filed Oct 2, 2026 · Fuel system, Transmission · WA

After application of the most recent battery recall/Software update, 68C, the vehicle operates differently than it previously did. In fact, it now nearly stalls while climbing a hill to my home when the battery charge indicated is less than about 35%. Vehicle speed drops from 25 to nearly 5mph, independent of accelerator pedal position, before the engine starts abruptly. Not only am I creating a traffic hazard for those behind me, but the cold gas engine engages at full load. Secondly, the overall response to accelerator input seems to be much slower, both in time and power, than before the software update. This causes issues when pulling out into traffic and is especially alarming when the Jeep won't respond as it did for the previous 50K miles.

Ever since the 68C recall, my jeep constantly changes back and forth from electric to gas and causes an unsafe driving condition. Some of the shifts are rough, and the vehicle has stalled out as well. The acceleration and performance has also gotten worse. The vehicle feels like it is holding back / restricted. I can floor the gas and the jeep barely moves and then all of a sudden it kicks in and has caused scary and unsafe bursts of speed. I have brought this numerous times to the dealer for performance issues and they were able to replicate the issue. I am on my third hybrid battery and only have 34k miles on the vehicle. I have been stranded multiple times and have had to get towed. This vehicle is unsafe and I say a prayer every time I drive it.

Subject: Safety Complaint – 2021 Jeep Wrangler 2.0L Fuel Pump Failure (Loss of power while driving.) I am filing this complaint regarding a 2021 Jeep Wrangler equipped with the 2.0L engine due to what I believe is a significant safety issue involving the fuel pump. The fuel pump has failed, making the vehicle unsafe and/or inoperable. A sudden fuel pump failure can cause the engine to lose power or stall without warning, creating a serious safety hazard, especially when driving at highway speeds, in heavy traffic, or while crossing intersections. A loss of engine power in these situations places both the driver and surrounding motorists at risk of a crash. What is equally concerning is that the replacement fuel pump is currently on a national backorder, with my dealership estimating approximately 45 days or longer before the part will be available. This suggests that many owners may be experiencing the same problem and that replacement parts cannot keep up with demand. As a result, my vehicle is unusable while I wait for a critical safety-related component. This creates a significant financial and personal hardship, including transportation difficulties, missed work, and additional expenses. A safety-related component should not be unavailable for such an extended period if this issue is affecting numerous vehicles. I respectfully request that the federal safety agency investigate whether fuel pump failures in the 2021 Jeep Wrangler 2.0L represent a widespread safety defect. If a pattern is identified, I urge the federal safety agency to require Stellantis to issue a recall or other appropriate corrective action to protect vehicle owners and the public. Thank you for your consideration of this complaint.

I am filing this safety complaint regarding my 2021 Jeep Wrangler Unlimited Sahara Altitude. The vehicle is experiencing a fuel gauge/fuel reading malfunction. The gauge does not accurately reflect the amount of fuel in the vehicle, which creates a serious safety concern because the vehicle may run out of fuel unexpectedly while being operated on public roads. This defect places me and other drivers at risk, especially if the vehicle stalls in traffic, on a highway, or in an unsafe location. I am requesting that the federal safety agency review this issue as a potential safety defect.

I went to start my Wrangler 4XE today and had a "Service Charging System" error. The gas part of the Jeep was running, so I proceeded to drive it. I noticed when I came to a stop, the car would not accelerate, then when it did it was violent and bucking. At a stop light it sounded like it was going to stall so I turned it off and then it would not turn back on at all. I finally got it to turn back on and drove it a little further, at one point I went to accelerate and had the pedal all the way to the floor and it would not advance. I brought it to Auto Zone and had a new 12V battery put in, but it did not fix the issue. After a quick search, it seems like this is a common problem with Jeep 4XE High Voltage Battery systems. Jeep has recalled the battery at least 3 times now and I've taken it for the first two recalls already. It was extremely distressing to try to accelerate and it not move, and could have seriously been a safety issue if I continued to drive the car. I was in another state, Jeep has no 24/7 service to call other than roadside assistance, so I had it towed to Brubaker Jeep in Lancaster PA, but I live in Virginia and had to rent a car to get home.

The high-pressure fuel pump (HPFP) failed internally while I was driving at night, causing the vehicle to suddenly stall and shut off completely while my children were in the vehicle. This resulted in an immediate loss of power and created a dangerous situation in traffic. The failure caused metal debris to spread throughout the entire fuel system, and the dealership confirmed that the system requires full replacement. I was quoted approximately $15,000 for repairs. This vehicle previously had a manufacturer recall related to the fuel pump that was completed in 2022 and is now listed as closed. Despite the recall repair, the same failure occurred again. This demonstrates that the recall remedy did not correct the defect. The sudden engine shutdown without warning presents a serious safety hazard, especially at night and with passengers in the vehicle. Its been at the dealer ship for a month.

My 2021 Jeep Wrangler Rubicon (3.6L eTorque, automatic transmission) has had recurring drivetrain instability since about 2,000 miles while under factory warranty. It intermittently has high RPM flare during acceleration, delayed shifting, shuddering under load, and abrupt engagement. At low speeds (about 10–5 mph), it harshly downshifts, grabs suddenly, RPMs jump up and down, and it can feel like it will stall; it has stalled intermittently. Braking feels inconsistent, and at times it feels like the vehicle resists braking or surges before slowing. The forward collision warning/automatic emergency braking has activated with no obstacle present, and the power steering assist has been lost intermittently. There is also an engine tick and a high-pitched whining noise from the engine/drivetrain area. 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. After installation of a new Mopar remanufactured transmission and torque converter, the same symptoms returned. AAMCO has now found that the new torque converter failed, with metal shavings throughout the transmission, in the fluid, and at the bottom of the pan. I was advised that the vehicle should be sent to a Jeep dealership because no codes are currently present. I was also advised that the dealership may replace only the torque converter rather than the entire transmission, despite recurring failure and metal contamination. This presents a safety concern due to loss of acceleration, unpredictable torque engagement, stalling, unintended braking activation, power steering loss, engine/drivetrain noise, and repeated drivetrain failure. I have all the records if requested, file is too large to send in the upload area.

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.

My vehicle is experiencing EV system failures, stalling, and system shutdown warnings that make the vehicle unsafe to operate. These symptoms began after a recall repair that was performed by the dealership. The dealership initially stated the recall was repaired, but the same symptoms have continued and have now worsened. The vehicle will display EV system warnings and will stall or shut down systems while driving. The air conditioning and other systems also shut down as the vehicle attempts to protect the electrical system. I have brought the vehicle back to the dealership multiple times regarding this issue. Despite the vehicle showing the same symptoms associated with the recall, I am now being told I may have to pay for additional teardown work unrelated to the EV system. This vehicle has become unsafe to drive, and I have requested assistance and escalation from dealership management but have not received a resolution. I am filing this complaint due to the safety risk posed by the vehicle stalling and shutting down systems while in operation.

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.

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
